SOURCE: Generac 4456 does not start on power loss

I install and work on these everyday. If you hooked up the transfer switch you probable have a control wire wrong. check the utility power sense wire. That lets it no when to start in auto. it could be a relay or fuses. or a control board.

SOURCE: Generator Transfer Problem

There isn't much you can do with servicing the generator set or transfer switch unless you've got lots of experience in diagnoising semi-conductors and electronic components.

Depending on the age of the system, it would be benificial to have a qualified service tech take a look at it.

As an electrician, I've installed several back up generator sets in homes for customers and have had a few of these automatic transfer switches with intermittent operation issues. Sometimes it's the switch and other times it's the Generator that is causing the problems.

Hope this helps, and best regards!

sounds more like a fuel problem not oil being spilled on it but check the oil level some have a low oil shut off see if you can keep it running spraying carb cleaner in the air filter that will tell you if it is a fuel problem more so a fuel problem if you left fuel in it for more than 30 days

Generac Guardian 12 KW Model 04456-2 shuts down on overspeed in cold weather


Leigh,
See my 5/22/12 comments on my "overspeed fault" problem resolution [Generac 43903 standby Generator overspeed indicator on starting] . If it only runs for a few seconds and then quits, you may have a similar condition to the one my unit had. A good technician should be able to diagnose the problem and determine if you have a similar failure to the one I had, or one of the other causes suggested by RSG000.

Generac 15000 portable generator: during use the motor revs extremely high and then shut off occasionally.


The reason its shutting down, is probably because its going in to overspeed and the safties are shutting it down to protect the engine. is it doing it under a load or no load.

You have a fuel delivery issue that can be dealt with by cleaning carb or replacing it. If you do replace carb has to be adjusted to the motor.(idle, mixture)

My 18RESL Kohler Propane Generator ran for 8.5 hours and shut down for overspeed. later it started up again and shut down for under frequency. Now it won't even turn over. Where do I start. I checked...


You have to reset it because it locked out on on under frequency. Just pullout the fuse on the control panel and then reinstall it a couple of seconds later. Now it will reset the fault codes. Hope that helps.
