Rheem criterion ii troubleshooting
Asked Dec 30, 2009, 02:41 PM
I have a Rheem Criterion II gas furnace, that quit working. I checked it out, and found that the ignighter would come on, the gas would start, and then it would shut off. Figured it was the flame sensor. Before I could sand or replace it, it quit even doing that.
I didn't get voltage off the transformer, so I replaced that, and the flame sensor. Now, all I get is the right most green light on the controller board. The middle green light and the amber light don't light.
Does this mean a new controller board?
