Ours was the same way. it had the light, but saw some units without the light on the switch.

After running for awhile, shut down, and restart 30-60 minutes later from inside...it starts right up.
Some of the 4000's do this and some don't. Luck of the draw.

x2 Tried that and works well. Saves a lot of wear and tear on starter.

I forgot to mention that you have to physically hold the linkage open with one hand while you hit the start button. Even if it's cold, after you prime it, hold the linkage open and it should start right up within a second or two.
It's a known problem that I think has been brought up on this forum, and several others I visit. Even Onan is aware, but there is no fix other than holding linkage open.

I have had my choke stick open many times.... Take the cover off and see if you can close the choke manually. When I do that it always fires right up, if not it takes a lot of cranking. I keep meaning to lubricate it, but I don't use it very often.

I live in Ottawa, Ontario, Canada and I have a 2013 Sunseeker MH with an Onan 4000 generator.
I put gas stabilizer in my fuel and run the MH engine and the generator periodically throughout the winter.
I can start my generator, after priming from the switch w/the red light as mentioned herein, even though the temperatures have been as low as -25, when my cabin batteries are right up.
I sometimes have trouble with the cabin batteries lacking the charge necessary to start the generator, but I get around that by starting the truck engine first and letting it run and warm up a bit before I try cranking the generator.

Sawdust In Unit

On a prior unit, I had the same starting problems. As it turned out there was sawdust, from the factory, in the gas bowl. After a through cleaning all was well. You can easily check the bowl and spray some gumout around and maybe save yourself some headaches.

I am pretty sure I do not have a light, I've never seen it at least. I am not even sure the switch does anything? Can someone tell me the correct procedure for starting the cold generator? How long to depress the switch if there is no light? How to tell if it is even doing anything? Thank you in advance.
if you have no light on your Prime switch inside something may be wrong ???
Try your outside Prim switch,,, hold for 20 seconds they try to start Genny !!!

This is the same problem I have had with mine for 2 1/2 years and moving the rod solved it. The rod with the bend in it needs to be moved to the left. It goes behind the metal plate on the right. I did the monthly exercise yesterday when it was in the upper 40's outside and it started right up after a 10 second prime. It used to take 2-3 tries at cranking after priming for 20 to 30 seconds.

Hope the pictures help.

Thanks guys! I also have had issues starting my Onan 4000. I usually had to press the prime for 5 second , release for 5 seconds and do this 3 or 4 times and then try starting. It would take about 15 seconds to start. I just ran out and moved the choke rod to the left, and it seemed stuck. I primed it for 5 seconds and it started right up first time. GREAT, thanks again for the tip!
Any suggestions on were to lubricate to correct stickiness?

Not all gen sets have a light. If you're does not have a light then hold down the stop switch till the hour meter lights up to see the hours then count to 10..then hit start..never crank gen set more then 19 seconds at a time.you are over heating the starter and you will smoke the start.

I use a quick squirt of Valvoline Starting fluid/spray with upper cylinder lubricant. Remove the air filter and give it a quick 2 second squirt hit the start button and off you go! Reinstall the air filter and let it warm a couple of minutes before turning the breakers on. NOTE: most diesels do not like starting fluid and I know nothing about propane systems so check before using on anything other then a gas powered generator set.

I just sprayed some WD 40 in the hole where the rod goes today. We’ll see if that helps

That’s not the way mine works. Once it is unstuck ( moved to the left) it should stay there and the choke is “ON”. Once it warms up, the rod goes to the right and is in the “OFF” position, which is where it gets stuck at.

Thanks, let us know if it helps. I went out this morning and gavea look at the generator choke rod. It's still loose and so I primed for 5 seconds and it started right up. When I say 5 seconds, I mean from once I heard the fuel pump start. Pressing the prime/stop button takes 3-4 seconds before the pump starts. Inside, I can see the red light come on and the hour meter appear.

Thanks to members of this forum for teaching me how the generator should be started. We have owned our Lexington for two years now and have spent lots and lots of time priming and cranking!! After reading this thread I went to the camper and cranked the genset for a count of three. No start. Counted to 5 and cranked again. Started right up.
I checked the action of the choke and it is fine. Double checked that I reset the altitude adjustment to sea level again and checked the adjustment on the choke. Mine has both. When we get to the mountains this summer I will have to adjust both.
Always learning new things on this forum and others I have read. Thank goodness there are knowledgeable people willing to share.

Yes, it is working. I unstuck the rod and sprayed WD 40 in the hole. Genny started right up. Shut it down. Next day went out and choke was in the proper position (unstuck position to the left). Maybe that is the easy fix.

Hmmm, I'll see how the WD40 hold up before I go spraying anything else in there. I'm not sure what mechanism is even in the choke rod column. I would suspect some type of heat coil/spring thing. White lithium grease can turn into a clumpy wad of unmoving material that does more damage. Maybe someone else wants to try white lithium and see how long it lasts.

Never had White Lithium clog anything up !!!
WD is a good cleaner & temporary lube !!!
If you are worried about white lithium,,, maybe try a dry lube ???
