120 Volt Electric In RV Keeps Cutting Off When Running Generator

by Eldon Offutt

Hi everyone.

I just bought a 2005 Coachmen Freedom 27ft class C. We love it, but we're running into a problem. When running on shore power everything works fine, but when running on the generator, My 115v. system will just quit after awhile. A/C and receptacles just shut down. Oddly though, the generator keeps right on going, and no breakers that I can find are tripped.

After awhile (after it cools I assume) it will work again, but only for awhile and then it shuts down again. It's over 100 deg. here and very hight humidity so I'm wondering, is there some sort of thermo-couple that is causing an open and then reconnecting when it cools? If so, where is it and where can I get a stronger one?

I've read some posts about the power converter and the "Automatic Transfer Switches" could these be the problem? Help! We're in an RV park right now so no problem, but we leave Sunday for a 7000 mile trip!

ANSWER: Hi Eldon thanks for submitting your question on our Ask An RV Question Page.

Based on your description I would say the problem is not with your RV's Power Converter. The problem could be with the Power Transfer Switch, but I am more inclined to think that the Voltage Regulator is the culprit.

I am assuming that you have checked for any loose or corroded connections and tightened or cleaned them. The Voltage Regulator should be located in the control box of your generator. I believe that your RV is equipped with an Onan Generator. Sorry I cannot give you the exact location of the control box as the location varies by model you have.
