Question

I just bought an multi family home that has been vacant for two years. All the units have the rheem powervent with the power glo. I am having trouble with one of them. It is hooked up properly, but when I try to "turn it on", the glow plug glows. When I put on the gas, the burner ignites but then it shuts off immediately. I have not had this problem with the others. Have any idea?

Accepted Answer

Yes I do have a good idea of whatyou describe.

In the burner assembly, you have the hot surface ignitor and a flame sense rod. Once the main valve is engaged the flame sense rod has 3 seconds to verify. This rod can get coated with a film that insulates it 's sensing. Clean the rod with sand paper or sand cloth and this should take care of the problem.

There was another type that actually used the ignitor itself to recognize flame. These were not as dependable as they aged and the ignitor would light but loses sense. These I just replaced insted of trying to clean.

I am available for followup.
