When looking at the control board, it indicated "high oil temperature." After three days at the dealer, it still isn't known what is the problem. We are now considering changing out the generator to an Onan 5500, even at a substantial cost. Has anyone else had this problem with a Generac?

I first have a few questions and if you feel your answers fit you can try the solution.
1. Do you have many hours of run time on the generator?
2. When you run it do you load up the generator or just have it run just lights and battery charger, etc?
3. Has the oil. filter been changed recently?
4. Open up the air filter and check filter if it is clogged or not. Clean
If you don't run generator often under full load the gas may have formed varnish in the carb. This may make it run lean which might make it run hotter than normal
Anyway I suggest to buy a spay can of carb cleaner
Open up the air filter and while the unit is running spray directly into the intake of the carb. You want to spray a lot and it may even stall out. That's OK. I would continue to spray for a few more seconds and then let the unit sit not running. If you have any varnish in the ventura or around the needle valve opening it will help to remove that old gas varnish buildup.
You can try this a few times and see what happens. It is a cheap idea to save you a lot more money in a new unit.
After awhile start and run it and turn everything you have on that you can that is 120 volts inside. I mean load that baby up and see if it overheats again and shuts down.
Let us know if you will try it an see.
