After having the sensor cleaned/replaced twice, and having another failure, I had the coolant flushed and replaced in April 2010(after another failure). The failure occured again a week ago, showing up as a failure after a weekly autorun. I reset the autorun, and it did run with an all green panel after the run. On the next run, it again faulted. I reset the run, and it shutdown with a red led. I tried two manual starts, and got the same shutdown and fault led. I contacted the dealer, and they are coming out again to check it out. Unfortunately, the big storm and a full snowy driveway kept them away today, but the electric service continued through the storm, so no problem.

The unit was installed in Oct 07, and the problems started in 09.

Any thoughts on my continued problems?

Did you have the sensor replaced when you had the coolant flushed there has been another sensor update in late 2010. I would also check all the pins that plug into the control board to make sure they are seated in the plugs. Sometimes in the female side of the plugs the pins get expanded and you may have to take a small dental pick and squeeze them together little bit to make the make the connection.

I not sure this will help and I don't know your model # but I had a problem getting low coolant/high temp failure message on a unit I was working on. The replacement probe part# was 0E2507. I had the same problem again and found there was a new part to replace 0E2507. It is 0H1827 coolant leve probe and 0H1851 interface module. I believe the kit containg both parts is 0H50540SRV. I installed it and have not had a problem up to today.
I found the PIB on it, will try to attach it. Hope this helps.

The tech is coming tomorrow. Will ask him about the fix. If he can dig out the generator from the snow. Will let you know whether it fixes the problem or not. Thanks for the help.
