Kohler Generators FAQs

If your Kohler home generator has been operating during an extended power outage, here are a few tips from our service team to keep handy. Please note that these are merely suggestions and maintenance guidelines. Please refer to your owner’s manuals for exact specifications and maintenance schedules. It’s very important to service your generator correctly and in a timely manner.

Q: How do I open the unit?

A: When you purchased your generator, you get a literature packet that contains the key. Insert the key into the lock and turn it 45° to unlock. Lift the hood.

Q: How do I turn off my generator?

A: Open the hood. Move the circuit breaker to the OFF position to stop powering the house. The circuit breaker is located below the black controller. Once switched OFF, let the generator run for 2‐5 minutes then press the blue OFF button located on the controller.

Q: How long can it run before I need to check the oil?

A: Be sure to check the oil every 8 hours and change the oil after every 100 hours of use. If this is not possible, at the very least, check the oil every 24 hours. It’s very important that the oil is checked and changed correctly in a timely manner to avoid damaging your generator. It’s important not to rely on the low oil pressure switch (which is very different from a low oil level switch) to shut the machine down. The damage will most likely already be done by the time this occurs.

Q: How much oil will my generator consume?

A: Since variables such as engine hours, load, model, and other factors influence fuel consumption, there is no standard amount of oil being consumed. As long as you check the oil level and change the oil as instructed then your generator should be in good condition.

Q: What type of oil do I put in the generator?

A: We recommend 5W30 Full Synthetic Oil. If that’s not available, then you may also use conventional mineral base oil. If the engine has been serviced before and filled with conventional oil, then refill it with conventional. It’s important not to mix the synthetic and conventional oil. It can damage your engine.

Q: Where is the dipstick?

A: The dipstick is located on the back of the engine and has a yellow ring or handle on the end of it.

Q: How do I check the oil?

A: After you turn off the generator, allow the engine to sit for 2 minutes to let the oil settle. To check the oil level, pull the dipstick from the back of the engine, wipe it with a clean rag and place it back into the dipstick tube. Pull the dipstick back out and examine the end of the dipstick. The end of the dipstick has crosshatching between an ‘F’ (full) and an ‘L’(low). The oil level should fall between these two markings. If it is towards the low end, add oil.

To add oil, find the yellow cap (that’s engraved with a picture of an oil can) on the front of the engine. Add a few ounces of oil then check the oil level again by inserting and removing the dipstick. Repeat these steps and continue adding oil until the level is at or near the ‘F’. Do not overfill the engine. If the engine has been serviced before and filled with conventional oil, then refill it with conventional oil and NOT synthetic oil. It’s important not to mix the two oils. Once oil is at a desirable level, start the generator by pressing the AUTO button. After the generator is started, flip the circuit breaker to the ON position and the generator should be supplying power to the house.

Q: What do I do when the water rises above the generator?

A: If it’s safe to go outside, turn your generator OFF. If you can’t get to your generator and it continues to run while submerged in water, there will most likely be internal damage. There is not much else you can do. Remember, water and electricity can be very dangerous and if the generator is submerged, you will have both conditions.

      Don’t purchase Kohler it will not start in the winter below 15 degrees and Kohler will not replace the unit even though it’s done this from day one. I purchased the carb heater and it did nothing. The fix from the tech…I have an electric heater running inside the Kohler box at the cost of $ 48.00 per month. I’ve complained over and over, the tech has been here several times and they still won’t replace this lemon.

    Informations should be spread regarding the safety usage of generators. It is very vital that you know that generators might expel carbon monoxide that are very poisonous aside from that generators can also cause fire. This Kohler power supply looks very nice and I hope this is safer from other generators

    Do you still have promotion to give free OnCue software for the people that will buy your 48RCL generator now? I travel a lot and need to check on the house from time to time.
    I have freezer with a lot of food in it and big aquarium with small scarlet sharks in it.
    My electricity has to be ON all the time.

    I downloaded the demo version of OnCue and I love it!!

    How do I reset the time & date for it’s weekly test run? I’ve got the OnCue Program but don’t have any areas I can enter or change the day or time. Look in the OnCue Manual but not sure if it’s the ATS Exercise or what

    • Cindy Lee
      March 19, 2013 at 4:32 pm #

      Hey Ron, the OnCue Home Generator Management System doesn’t set the test time, but it can make your generator run another exercise.

      To change the exercise time, you’ll need to set it manually on the generator or with the ATS controller. Each generator and ATS is different, so please email your generator’s spec and serial numbers and your ATS model to GPGsocialmedia@kohler.com so we can better assist you.

      Please let me know if you’re having trouble identifying that information and I’ll be more than happy to help. – Cindy

    I had a 20 RESAL installed in December 2012. On 04/08/13 it did not run it’s exercise cylce. I contacted the Kohler installer about this issue. There is a red blinking light on the generator and the display says main power overload. Still waiting for the installer to schedule an appointment to come to my house. What could cause this? Right now I have a generator that is useless.

    Is there limitations on the warranty if any licensed electrician installs the generator?

    • Cindy Lee
      April 24, 2013 at 9:47 am #

      Hey Bill, the Warranty Startup procedure that Kohler recommends ensures that you receive the full five-year warranty that is available when you purchase your generator.

      Technically, the warranty starts on the day the unit ships from the factory. If the unit sits in a warehouse or on a dealers floor prior to being installed at a customer’s home, this could mean a loss of warranty coverage (from a time standpoint) because the only date on file Kohler has is the date it left the factory.

      However, when a Warranty Startup is performed by a Kohler dealer or distributor, the warranty start date gets bumped up to that day and the paperwork with the Warranty Startup date is filed at Kohler. The best way to avoid paying extra for this option is usually to have the local Kohler dealer perform the installation so the Warranty Startup is part of the installation package.

      If you have your own contractor installing the generator and transfer switch, your local Kohler dealer or distributor for a nominal fee (depending on distance traveled) can come out and perform the Warranty Startup as a way of updating your warranty start date and ensuring that the unit was installed properly.

      Although these units are not complicated to install, even licensed contractors can make mistakes during the installation process because they are not familiar with the technology.

      If you need a list of authorized Kohler dealers in your area or have price questions, your dealers can help you out. You can enter your zip code here to find the dealers in your area: http://khlr.co/b9Uy.

      I hope that answers your question. Let us know if you need anything else.

    If I self install a 14RESAL, will Kohler honor the warranty on the unit?

    • Cindy Lee
      June 6, 2013 at 8:59 am #

      Hey John, thanks for reaching out to us. If you read some of the comments above, you’ll see that Bill asked the same question. Please refer to those comments for more detail.

      In a nut shell, in order to get the full warranty for your generator a Warranty Startup procedure must be performed by a Kohler Generators dealer or distributor when you purchase your generator.

      If you or your own contractor installs the generator and transfer switch, your local Kohler Generators dealer or distributor (depending on distance traveled) can come out and perform the Warranty Startup as a way of issuing your warranty and ensuring that the unit was installed properly for a nominal fee.

    I have a 20kw Kohler and one of the Kohler transfer switches. I have it set to exercise weekly in the unloaded mode. The transfer switch has forgotten to exercise after many weeks of doing it on schedule. This occurred immediately after running for 3 days. There are no error codes. I reset the exercise cycle and it ran successfully, but I am not confident that it will run again on schedule next week. Any thoughts why the transfer switch forgot to exercise?

    Two questions regarding the Load Control Module —

    1 ) Are the relays in the Load Control Module NO or NC? (ie, is power applied to them to command the load to shed, or is power constantly applied to keep the load online?)

    2) The manual calls out wire sizes to be used on the control bus wiring for different distances between the generator and the LCM. Is there a distance limit between the CT installed in the ATS and the LCM?

    Hello Ms. Cindy Lee:

    I recently purchased the 20 KW generator and am very pleased with this unit. I have 6 hours run time and decided to change the oil. Upon changing the oil, the oil flow through the drain tube was very slow taking about 1 hour to fully drain. I had the drain valve in the fully open condition. The oil drained was 5W30 synthetic and at hot engine temperature. I also had removed the oil fill cap and dipstick so as not to create a “vacuum.” Is this drain time normal? Your thoughts/comments would be most appreciated. Thank you.

    Regards,

    Ken Fries

    • Cindy Lee
      August 5, 2013 at 11:44 am #

      Hey Ken, according to your message, it looks like you changed the oil correctly. The only other thing that wasn’t mentioned, but I’m sure you did, is opening the oil drain valve. A partially opened valve could be what’s causing the oil to drain slow. For location of the valve, please refer to the Service Manual, TP-6805 pg. 15. If you need further assistance, please don’t hesitate to send me an email at GPGsocialmedia@kohler.com.

    I have a 30RES that I have had for years. I recently switched this unit from LP to Nat Gas. I used the installation manual to make this switch and did everything to the letter, i.e. pressures, regulators, lead from 65Ato 70. Upon completing the project, We went to test run the unit and it will only run for a few seconds then shut down on Undervoltage. I did verify this and I have 115VAC from one line to the other, and my engine speed is low (45hz) any advise?

    Which is better for the weekly test run? Loaded or unloaded test.

    Thanks

    • Cindy Lee
      October 3, 2013 at 9:00 am #

      Hey Jim, I’m sorry for the late reply. I did see your comment and have been trying to find an answer for you.

      We don’t know for sure which test is best for your home because every situation is different, but we often recommend a loaded test. However, some homeowners choose to run an unloaded test because their generator may not be set to power their entire home.

      It’s always best to refer to your owner’s manual and seek help from an authorized Kohler Generators dealer, but here are some general recommendations from the Field Service team:
      Best: Full speed loaded because that is how the unit will be used in the event of a power outage.
      Better: Full speed loaded
      OK: Variable speed

      If you have any more questions, please feel free to let me know or email the Customer Service team at generator.feedback@kohler.com.

    I bought a new 14 kw resal working great . I read oil should be changed ever year or at 100 hrs. Is there a recommendation for the first oil changed at a earlier time frame. Thanks Tom

    • Cindy Lee
      October 3, 2013 at 9:01 am #

      Hey Tom, congratulations on your purchase! There is no “first oil change” other than what’s listed in your owner’s manual (once a year or after 100 hours). As long as you follow manual, you should be fine.

      We do recommend that you check the oil level before running your generator for the first time. We test all of our generators before they leave the factory, so they come shipped with some oil still inside of them. Directions for checking the oil is also outlined in the owner’s manual.

      Please let me know if you need some more help and I’ll be more than happy to connect you with our Customer Service team.

      Thanks, Cindy

    Tom:

    Refer to my August 5, 2013 oil change question. I changed the oil and filter at 6 hours run time. There was some metallic flakes in the oil but not excessive. My oil did drain slow. I removed the front cover (not that difficult) and the oil drained out much faster. This was due to my yard slope (and gravity).

    I just purchased a 20 Resal model generator. I have read that you should not mix synthetic oil with standard oil. So what type of oil was the unit serviced with at the factory?

    • Cindy Lee
      January 2, 2014 at 11:23 am #

      Hey Mark,

      We recommend and service our generators with (Mobile 1) 5W30 full synthetic oil.

      If that’s not available, then you may also use a conventional mineral base oil. If the engine has been serviced before and was refilled with conventional oil, then refill it with conventional. It’s important NOT to mix the synthetic and conventional oil. It can damage your engine.

    I have unrelated problem with OnCue Ver 3.5.77 (and the same with 3.2 and up) with PIM field description.

    PIM description likes to erase itself and revert back to defaults from time to time.
    Especialy after running the generator test.

    Could you pass it to the software team.

    It happens on Windows Vista 32 and 64 bit and on Windows 8 and Windows 8.1

    In the current version of oncue that is with the rdc2 firmware 5.4.2 zip, the writeable parameters will not apply if changed over the network. The response is “Unable to set parameters” .. Example parameters trying to be changed: exercise mode from variable to full speed unloaded cycle… exercise interval from weekly to every other week. The error listed in the window is “The parameter cannot be set to the specified value” for each attempt.

      Hey Tom, thanks for reaching out to us.

      The instructions to reset the maintenance message can be found in section 5.2.5 in your Operation Manual titled “Resetting the Maintenance Timer.”

      Please let me know if you need any additional help.

      Thanks,

      Cindy

    I have customs that have just installed the resa 20kw. They want to know how long the generator takes to kick in after power failure. How long does it ruin after the power goes back on, when to check and change oil.. etc. Is there any kind of flow chart or cut sheets that list this info? Thanks

      Hi Todd,

      I’m sorry for the delayed response. During a power outage, our KOHLER home generators can detect when there’s a power outage and will automatically restore power to the home in about 10 seconds or less. All of the maintenance information (e.g., checking oil) can be found in the generator’s operation manual.

      Please have your customer follow those instructions closely. Also, please reference them to this FAQ: http://blog.kohlergenerators.com/faq/.

      If they need immediate assistance they should contact their local KOHLER Generator dealer here: http://www.kohlergenerators.com/sales-service/find-a-dealer.

    Just an FYI for the cold weather folks….I decided to check my generator, 20 RESA, today ahead of the impending nor’easter and noticed the fault light was on and an error message of low oil pressure. I had just had my unit serviced my a Kohler tech and an oil change was preformed. After reseting the unit, checking the oil and running the unit for 20 minutes, all was well.

    I called the my tech and he explained to me that during this extreme cold weather he had a few units display the same fault message. He said it has to do with the outside temperature almost at 0 degrees and the oil being to thick due to the cold.

    The instruction manual calls for 5W/30 synthetic oil, which I use. Can you use 0W/30 synthetic oil as well?

    I can’t see this being problem being normal. What do people in North Dakota or Canada do? These people deal with extreme cold all the time.

    Thanx for your time.

      Hey Steve,

      Thanks for your comment. We recommend 5W30 Full Synthetic Oil. If that’s not available, then you may also use conventional mineral base oil. If the engine has been serviced before and filled with conventional oil, then refill it with conventional. It’s important not to mix the synthetic and conventional oil. It can damage your engine.

      Please see this FAQ for more helpful maintenance tips: http://blog.kohlergenerators.com/faq/.

      Steve,
      Sorry to hear about your trouble with the cold weather starts. We don’t get it near as bad as you do, but a several weeks ago, we were -10F here and mine started right up. As a fellow owner, I would offer the following ideas:
      1) Is the battery the right size and required cold cranking amps? I measured the holder and put in the biggest battery that would fit and had the highest CCA.
      2) Are you positive that the engine has synthetic in it? If you didn’t do it yourself, I would certainly suspect that. You obviously know what thick oil does in winter from your note above!
      3) When it is up and running, does it run well indicating the carburetor is adjusted properly or is it constanting laboring or surging? Mis-adjustment greatly affects the starting capabilities of small engines.

      Hope some of this helps!!

        In response to your questions on my generator.
        #1 Yes it has the correct battery and the tech measured the cranking amps.
        #2 Yes it has Amsoil 100% Syn. 5-30.
        #3 No on running smooth it sounds like a hit & miss engine. Tech states there is no adjustment on that it’s set to run lean but miss will stop under load…..wrong.
        #4 Below 15 degrees it has never started even with a carb heater.
        #5 Gas company was here with the tech and gas preasure is fine.
        #6 Found bolts laying in the case x2 and carb was ready to fall off.
        #7 Tech said valve was freezing up…replaced valves no change.
        #8 Tech put electric blower type heater in the generator case and it will now start but cost me over 40 dollars a month to run the heater.
        #9 Have ask from the begining to replace the unit since it’s been like this from day 1 and it now has over 140 hours on it and was told ” we don’t do that”
        #10 The list goes on but I’ll stop here…. My tech now tells me everytime I call for the status of replacing this unit “we’re working with Kohler on it”

          Argh! Not a good situation at all. Being a small and large motor mechanic, and with your note that the carb had installation issues, I would immediately guess that the generator is running lean due to there being an air leak in the intake system. Too much air causes it to lean out the fuel mixture as well as HARD TO START IN COLD without pre-heat. It is impossible to adjust the carb to overcome this issue. Your statements above and elsewhere fully support this. I can immediately see that the issue is definitely engine intake related. My guess is that a gasket is missing or misaligned. If you can check that I am betting you are going to find the culprit. I wish I was closer…..! Not sure I am loving your tech person.

          Hello Mr. Steve and Mr. Phil:

          I wanted to comment on Phil’s comments regarding Steve’s carburetor gasket issues. I totally agree with Phil’s comments. A while back I had some hard starting issues with a lawn mower. I proceeded to take the carburetor off the engine to clean it. In this process, when re-assembling everything, I missed aligned the carburetor intake gasket. The engine would not start and I ended up taking the mower to a repair shop. I learned quickly that I was the culprit in this engine problem. As Phil mentioned be sure that a correct intake gasket is installed and the carburetor is bolted tight to the engine block.

          Let us know, Steve, how everything works out.

          Regards,

          Ken Fries

    Realized my 20RES was not exercising at the normal time. Installed in April 2011. Battery good, receiving proper line voltage, receiving 13.2 DC at both spade fuses. RDC control panel is completely dark and the unit will do NOTHING and will show no lights or LEDs. Is this a bad RDC at less than two years?!!! The unit has performed flawlessly on numerous occasions during the two years but I hate to think it is bad now. What could have caused this? Where do I get a new control board from? HELP!

        I dropped a note today. I called Kohler corporate and they agreed it seemed to be a bad board. They had me contact CK Power out of St. Louis and talk to the tech. Again confirmed a bad board. They had a new board to me the next day! I installed it, programmed it and the genset is working perfectly now. I sent the bad board back because they said they would do it under the warranty free of charge. Great service! I am still VERY concerned as to why the board went bad. The cost of the new one is over $800! Thank goodness I am still under warranty. What happens if it craps out again…. Sell the generator? I have well over $4K in it already. Scared of the reliability right now.

          Thank you so much for sharing your experience with all of us. I received your email and generator information and passed it on to Customer Service and our product developers.

          You don’t need to be scared. We stand behind our products and value our customers. I think your story can speak for that.

          If you ever encounter any more issues, you know how to reach us :)

            Must me nice, I’m still running my electric heater inside my unit so it will start. 150 hours and it’s been like this from day one and Kohler has yet to replace the unit.

            I will definitely follow up with you regarding the warranty, if necessary. I am sure things will go OK, but right now I had to pay up front for the part ($800+) . Kinda surprised me, being it is warranty and all. I just hope I get credited back right away. Thanks for your helpful thoughts and comments.

            I need your help. I have gotten no response from CK Power regarding refunding my money I paid for the warranty part. At present, I am out of pocket $872.11 for a part that is covered under my warranty.
            Can you check to see if there is a problem on your end at Kohler? I know you have all of my generator specifics, but let me know if you need more info. This is ridiculous for me to have to wait for a refund from your distributor. CK Power received the bad control board from me on 2/21/14, I have the tracking to prove it.

            Hey Steve,

            My job here is to connect you with the right people. I know that Customer Service was able to help you get in touch with the distributor in your area. Your distributor installed a new heater so the generator now starts and is fully functional.

            We’re staying in touch with them and are being updated on the status of your case.

    Had a 14kw RES installed by a local electrical contractor that is listed as a Kohler generator dealer (sales & service). I also have a service contract with them…
    Two questions:
    1) The unit only runs a weekly no load variable speed test. Should the installer have set up a loaded test once per month or at some other interval in addition to the unloaded test?
    2) The unit was installed on a stone base. is that sufficient as it appears to be leaning (not level)? Does the unit have to be completely level to run, and is the installer responsible for the condition of the base?

    Hello! Cindy.
    Just tried OnCue Plus on my iPad and over the MS web browser Ver 9 on Vista.

    I created account and all looks good.
    However when I am trying to add Generator it tells me that it is wrong Serial Number.

    I did try it on my iPad and on my Visata laptop, the same error.
    Looks like not all Serial Numbers are added to OnCue Plus yet.

    Could you check if all generators including 48RCL were added to the OnCue Plus data base, please.

    I do not have any problem adding generator under standard OnCue under Vista or Windows 8.1

      Hey Andrew,

      Thanks for reaching out to us. We are experiencing some technical issues. I’ve passed your email on to Customer Service so they can inform you when the issue has been resolved. I’m really sorry about the inconvenience and thank you for your patience.

        Cindy, we are making progress!

        OnCue Plus let me enter serial number of generator and now it is accepted and listed as an existing registered generator.
        However now it is asking me to activate generator and in order to do it OnCue Plus is asking for generator activation code.

        Do you know what I should do to get generator activation code?

        My generator is already active under OnCue standard version but it looks like it has to be activated separately under OnCue Plus again.

        Andrew

      • Andrew
        February 21, 2014 at 10:25 am #

        We are progressing even further with OnCue Plus.

        Since OnCue and OnCue Plus servers are two different servers I had to find the Software activation code from my original OnCue and re enter it in the “generator activation” screen.

        Didn’t know at the beginning what kind of generator activation code to use since it was not the same name that OnCue was using for it in the original OnCue. So remember the Generator Activation Code is the Software Activation Code you got when you purchased the original OnCue.

        Few bugs that I have noticed:

        1) can’t control anything.
        a) I have PIM module and I can’t change the status from “off” to “on” of the outputs.
        b) I cant start any test.

        2) Labels change on the PIM output lines (Yes famous labels that like to revert every few weeks to default names on original OnCue)
        a) don’t know if labels will revert to default here since it is intermittent problem on the original OnCue but I can’t change labels for output 1 and 2 (only output 3 to 6)
        b) no support for changing the labels for Input lines and no input line status are displayed

        3) Event status “Always On” from Original OnCue is displayed as a “Not Connected Non”
        Always On is already confusing on Original OnCue should be Standby On instead.

        Possible the Alwayes On status is missing and we have something new here that is not showing on the original OnCue?

        4) Exercise status in Maintenance screen, shows some random exercise default date when not configured
        (no year just day and month) Should show “Exercise Not Configured”

        5) The same thing in Control screen in exercise field, should show “Exercise Not Configured”

        6) main screen do not show PIM module.

        General remark about colors. I think it should be kept in the same color theme as original OnCue.
        It is heavy hardware we are connecting to and using all these pastel colors is bit out off bitten trucks.
