I have the 4000 and will never waste my money on another Cummins Onan gen. If you have ever taken one out of your rv you will find that these were engineered to be not user friendly. Cummins has done themselves a disservice by making junk like this. It’s like being in a bad marriage.

Good job

Glory be!!! It was a serendipity that I found your video. My Mantra is "little to no effort with little to no cost". It was fulfilled in this easy fix!

Hi, can you please let me know How tall is it from the bottom to the level of the metal plate of the buttons?

Thank you!!!!

thank you, it is helpful as I am looking for my very first camping at this site in the coming week

Thank you! First rv with gen. It was scheduled to come at a certain time but we are at a full hook up spot. It came breaker on the generator reacted and flipped off. Not thinking used your way and came on and the GFI was reset in kitchen and we had air and power. Thanks you.

I wanted to give you a shout out. This resolved my 15-20 min run time issue.

I'm very happy with the my Cub Cadet ( 4 Years old) the oil change access not so much. Added a 3/8" x 3 1/2" long pipe nipple and cap. Drains into my basket much easier. Other then that for my yard it's a good machine. Spend the extra $ to get the hydraulic shift. Makes reverse or forward movements very smooth

i got the trailblazer awd 2024 whit the same engine and i like mine i like to know do you like yours so far

I lowered my oil level some but it still won't stay running. Bypassed my oil pressure gage too.

Solved my problem with the shoot switch!

God bless you brother. From a 67 year old fleet mechanic that has been in the business beginning in 1977 .Sometimes you discover something like this and it can save a ton of heart acke and money. I am working on basically the same gen with this issue but had oil leaking and worn out belt ,tensioner cracked belt drive coupler ect .I scince youtube has so much valuable information research most repair jobs that I have not done numerous times for just such information that in so valuable. Thank you for this information as the intermittent cut offs was the straw that broke the camels back with the customer wanting a 1000 hour service done. I feel I would have had a comeback without this video..even if just because I filled it up to the perceived proper level.

Do you check it with the dipstick screwed all the way in?

This is the worst video and the stupidest information I've ever seen

Thanks so much!!! After cleaning out some mouse made messes, I must have tripped this switch, you saved me a trip to the dealer and some $$. Thanks a big bunch!!

Dayummm! cool video

One slip of the wrist and you have the Exxon Valdez all over your garage floor....what kind of moron or derelict designed this oil plug? What a stupid set up....

Thanks so much. My husband has his Club Cadet for a month or 2 and it was working. He stopped it and it wouldn't restart. He couldn't figure anything out from the manual and I found your video. It was either the side button or the sparkplug, because he did them both before getting back on and now it works. THANKS!

Keep forgetting that circuit breaker by the genny! Thanks for reminding me and $aving me $$$ and sanity!

Mine ran for 40 min. Plugged it in and it bogged down and died. Will not start again. Has gas, new plugs. Also was not outting out 110

So we flipped the switch and have tried all other suggestions and still have no power coming in. Onan works great. Transfer switch box has power when plugged to shore. Any other suggestions?

Thank you so much! You saved me. Much appreciated.

I rented the RV from El Monte in Vegas. They tried to repair, but failed. They sent us to our journey without a working generator for ac and heating. Later they made all these wrong suggestions from the web. With your tip I could easily fix the issue by myself. THANK YOU for saving our holidays!

Onan generator has so many problems. The design is not even ergonomically for repairs. I wish Honda would make one so people don't have to go through the hassles.

Thank You Sir. May you be blessed for sharing. I have ONAN 4.0 KY-FA/26100H. (Specs call for 1.6 quarts 5w-40 oil. I drained all the oil. (not sure how much was in to begin with, looked full by dipstick)added exactly 1 quart of 15w-40(had on hand and fine for summer time) She started right up. I let if run for 10 mins then switched to circuit breaker on mode, then powered up new 13.5K btu AC with no soft start and she is still puttering perfectly along powering everything with a 2psi fuel pressure at the carb. I'm using an after market fuel pump and auxiliary tank from 20' aft. If that 1-quart wonder trick doesn't fix it for good she's getting her ass thrown out on the street and getting full time space replaced with her two Honda 2200 back up sisters.

Nice

Thanks for sharing

Awesome tips!

Would it be better to pump it out where you fill it,hand pumps at harbor freight

Thanks! Had a KN on for a year now, just had to clean and recharge it. Nice Jeep btw, 2016 JK here. 😊

Well, apparently Cummins Onan and this dealers are still completely unaware some 5 years later! We have a brand new generator (2023) that has the same dipstick and thrown fault code 36. I just checked the oil level and sure enough it's showing full. Thanks for the video!

Thank you!

The problem here is that Onan states in their manual for the 4KW gennies to screw the cap in and then check the oil level AND THIS IS WRONG! To properly check for oil level YOU DO NOT SCREW IT IN! If you don't beleive me, go ahead and fill to the level indicated in this video (just above the add mark) with the cap screwed in, and then check it again with the cap NOT screwed in. It will show the level at the full mark. Onan simply needs to change these instructions and tell everyone with one of these units in any and all ways possible that they did not provide the correct info in their manuals. Another falsehood here is that you need to wait any more than a half hour or so for the oil to drain from the head to the crankcase before checking oil level. Here's another way to prove that I am right about this: drain the oil after a 15 minute or so run period to heat the oil up, and fully drain it. Then add the reccomended amount of oil which I think is 1.6 quarts (The 2.8KW requires only a quart, and in the 2.8 manual DOES say to NOT screw in the cap to check level). Then check the oil level on the dipstick without screwing it in and you will see that it WILL be perfectly at the full mark. The fact that Onan has misrepresented this issue in this case in my opinion qualifies for a class action lawsuit!

Thank you for this. My husband was in a motor vehicle accident and can not change the oil in our tractor. I am the wife and know that this job needs to be done but was unsure of the steps to take. I am going to attempt this today. Wish me luck ; -)

Walmart has a green one like this.

Definitely less messy if you pump the oil out through the filler tube. There's still going to be a bit left if you want to pull the drain plug, but it won't be nearly as messy.

Thank you. You saved my wife having to listen to me complain for another hour. I would have never figured this out on my own. Thank you again so much!

Is full oil level at cross hatch mark or at top solid line?

Thank you !

Thanks so much,just got mine and looking ahead to when it's time to change the oil.👍

I was packing the camper everything was working great for about an hour. All of the sudden the generator stops running. We started it back up and now it runs fine but doesn’t put out power…. Please help!!!!!

Hi. My fan stopped working. Is it wired to the battery? Thanks.

Thank You so Much for your Video We bought this Mower it would Start But wouldn't/t go so watching your video Was A Blessing got my lawn cut

I noticed that the transmission fan is not spinning on my Cub Cadet CC30 riding mower. Should it be spinning all the time or at certain times. If it should be spinning all the time when mower is running what could be the reason it stop?

Thanks. I bought one a few weeks ago with no operator manual. I wondered what the yellow key position was all about.

Ok 2014 coachman freelander. Onan won't even crank unless I have the v10 engine running. Is there anything that prevents the Onan from firing if it knows the v10 is already running? Assuming since they run off the same tank. (Yes, I need to take better care of my coach battery under my steps.)

Great video. No success but helped me a lot

OMG, IT WORKED!!! Since 2016 I've had this problem with my 5500 genset and could never find the fix. Siphoned out enough oil til it was down to the "ADD" mark and it started right up and runs like a champ... THANK YOU SO MUCH FOR POSTING THIS FIX!!! Still wondering though if the dipstick is the wrong length, or there should've been a baffle in front of the high oil sensor that the engineers never designed in the blueprints??? Or maybe the oil sensor is mounted too low in the engine... I had an Onan microlite 4000 in my last camper which was a 1998 model. It had the same dipstick and that ran like a champ with the oil at the full mark... Just didn't have as many sensors as the newer Gensets!
