    1995ish York Gas Furnace Running, pilot on, no heat
    I tried to start my furnace this morning and all seemed to come on except for the main burners. The pilot was out so I started that, the blower came on as before, but still no main burners. I had the thermostat replaced at the end of March. I believe this York is from 1995 and the model # is P1SPD20N10001A.

    Any thoughts as to why the gas is not flowing through the main burners? It seems odd given the pilot gas appears to come through the same line.

    I also reset the furnace circuit breaker for grins, no change. I also turned the gas on and off for grins, the pilot went out, so I relit it.

    Any feedback would be appreciated. Thanks, Rona

    Did you remember to turn the knob on the gas control valve to "on" after liteing the pilot?

    You bet. I moved the pilot switch back to "ON". I wish it was that easy, still baffled.

    Do you have a thermocouple on the pilot?
    You probably have a bad thermocouple. A five dollar part.

    Yes, I have a Honewell thermocouple (I had to look up a picture to be sure). Nice to know it is an inexpensive part. I have the HVAC people coming out next week. I was hoping it was something I could do at home, thanks so much for your feedback, much appreciated.
