22 KW Air Cooled - Evolution - Model 6551 with 200 amp transfer switch - Propane

Generator is NEW-- less than 2 hours.
has had 2 exercise cycles.

We were away when this last snow storm hit us. and today I realized I did not hear the exercise run.

So when I checked it has a 2399 error Stepper motor overcurrent.
opened the case and manually exercised the stepper arm.
( [url]https://www.generator-parts.com/manuals/home-standby/0H9172.pdf[/url] )
Then set it to off.. and manually started it.. it seemed fine.. Then I left in running and stepped inside..
Temperature is in the 30s.
Still have 4-6 inches of snow on the ground.

Walked and checked all gas lines (about 75 feet) no ice forming, no ice on the regulators (have 2 stages).

It cutoff again and this time it said error 1200. overun? anyway..

I started it and it cutover again with overrppm... reset it... pulled the 7.5 amp fuse. put it back then started a third time.. this time I hear the RPM seems high and I move the stator low and release it... It now runs for 15 minutes without error...

Now we don't get snow often but when we do, it can be gone in a day or hang for a week...

Should I have a cold weather kit?
Is that the root of the problems I have?
Thoughts?

thanks,
J

Call a service dealer.

Never saw "over run?" Did you mean over speed?

Would be still under warranty. Call a service dealer as others have mentioned.

Almost sounds like the stepper motor is unplugged or damaged, but yes, call a service provider.

Temps in the 30s are considered cool summer days up here! I don't think a Cold Weather Kit is even a consideration. In any event, it would not have any bearing on the errors you are getting. Call a dealer, and Good luck.

You said "I removed the stator low and then release it", I don't know what that means? Is the unit working properly now? Peddler

After shutting it down I manually manipulated the stator arm.. and then let it go back to the spring loaded position.

after that it seemed to run fine..
But I will wait till the exercise cycle this week and then make a determination.

Strange thing is it ran fine without any hiccups over 3 test cycles (killing the power company input), and a weekly exercise .. THEN it snowed hard-- (surveillance camera showed 3-5 inches on top and then 4-6 inches around the base.....) This is when it failed...

Now warranty question...
I did a self install- is my warranty still valid?

thanks,J

Are you possibly referring to the governor arm ?

Just for the heck of it, remove the front cover and take a look under the controller for the black cable that goes to the stepper motor. I had a problem a few weeks ago with erratic performance, and I found the plug was half out of the controller, making intermittent contact. I pushed it back in and the problem went away. The stepper motor must have been getting an intermittent signal and the generator would not run for more than a few seconds before shutting down in a huff. While you are in there, make sure the rest of the plugs are seated properly.
