Burner not starting
My wall heater is not functioning. I had a similar post last year, and this year the problem evolved.
Attached is the kind of wall furnace that I have.
The pilot fire does stay lit. Turing the thermostat on does not kick in the burner. Thus, for the past winter, I have been shorting the two Th to start the burner, and then it works perfectly. However, this method does not seem to always work for me anymore this winter, and shorting the Th even puts off the pilot fire.
I have done some basic testing (the numbers are same as of last winter).
With burner off,
Pg to Pg: 360mv
With burner on,
Pg to Pg: 250mv.
Pg to Th: 225mv.
Wondering if this sounds like a faulty thermopile? I actually did put in a new one last winter, wondering if trying another newer one would help.
Thanks in advance!
