Furnace model #7710-856 Presidential II
Well recently fixed two problems thanks to this site (that I wrote about before...the booster motor and the crossover duct repair) so now furnace is blowing heat, but now we've come across another problem.
The pilot seems to stay lit the entire day, then the furnace will kick on, and stay on until the thermostat temp is reached (ie it never shuts off prematurely), but once the burner/ blower goes off, the pilot also goes out!
I lit the pilot, and just turned on the blower to make sure the blower isn't doing it, which it is not. (if it did I guess it would probably mean a major gap/hole in the exchanger???? YiKeS! I have 3 carbon monoxide detectors in the home, and all is well, according to them).
I have yet to check the roof vents/etc for blockages, but I'm puzzled as to why the pilot only goes out right after the burners/blower shut down??? Anything else I should check? If it was a bad thermocouple, then why is the pilot staying on the entire day when the furnace is not in use?
It's becoming a real pain in the u know what to keep relighting the pilot when we need the furnace on.
Any input is appreciated. Thanks!
