You need to check frequency as the unit may simply be running fast which would also cause an over voltage. Make sure the governor is maintaining 60Hz. Peddler

In any case, resetting it and putting back in 'auto' is not a good idea if something is really wrong and for some reason you lose power. You don't want there to be a chance that the generator would be connected to the loads in the house like that.

Thanks for the replies. I will set the unit to "off" until I can figure out what's going on.

Could it be the stepper motor is either unplugged or just not functioning?

What region are you in? Are there signs of bugs and ants having gotten into the control board? I see a lot of problems with ants this time of year, they are attracted by warmth of electronics. They get in there and confuse the computer, voltage regulator, or both.

Uh-oh! When I was looking at the display to check out what was wrong, lots of tiny ants crawling around in behind the display screen. I'll have to take care of those guys......

They may have already taken care of you... :(

Thanks guys for the new "what to prepare for". Spring: add an insecticide around the base. Winter: Put a guard at the rear to keep generator cooling open. Fall: Put a small mesh fence around air intake end to keep leaves off the intake. Looking forward to something to do for summer. This is great forum and I have learned s lot. Thanks for taking time out of your busy days to share.

Damn, was hoping my hunch was wrong. Sorry.

I keep a toothbrush in my bag and am often lucky enough to brush them away and restore function. It all depends on whether or not they damaged one of the controller components, or are just confusing it. Keep in mind though, and I always tell my customers, that reliability is NEVER guaranteed once they have gotten in there.

Check the above mentioned engine speed issues before you go replacing the controller (it's not cheap). But if you truly were having speed issues you would most likely see an "overspeed" instead.

Wow our generators are susceptible to ants.

"The average ant can actually carry up to 50 times it's body weight, and some ants can lift an incredible 100 times their body weight !"


We will all be long dead and there will still be insects on this planet.

Yep, seen that quite a few times.

Usually pull it and open it up to vacuum them all out and then reverse and blow out all the rest. Little diatomaceous earth and hope for the best.
Sometimes it's a lost cause because the damage was already done.

Hi...i am a new user here. As per my knowledge resetting it and putting back in auto is not a good idea if something is really wrong and for some reason you lose power. You don't want there to be a chance that the generator would be connected to the loads in the house like that.
