Hello,
I have a 3 yr old vented Propane wall heater that is not working properly. The problem started with an occasional weak pilot causing the unit to shut off. Now the pilot is weak all the time and will not stay lit. If I bypass the pilot circuit and light the burner manually, it operates normally. Other things I have checked are the thermocouple. It works and will hold the pilot circuit open if heated with a small flame on a torch. Also, checked the pilot tube and orfice. The tube is clean, and I can put a .02 mm calibration wire through the orifice. I'm pretty good at engineering type issues, but this one has me stumped. Housewarmer (heater brand) tells me a new controller is around $200. Really don't want to go there if possible, especially since I'm not sure that is the problem. Anyone have an idea?
Thank you so much for your time.
Chris
