So I have had furnace man come out 4 times, plus the Gas company. Here is what has been done: - New thermocoupler - Two new gas valves - New Orface and line blown out - Gas company changed gas valve on outside of building.
Everytime I hear the "click" like the furnace is going to go on I listen for the burners to come on which is 99.9% of the time, never. It seems the thermostat is sending its signal to the furnace to start but with that "click" the pilot light goes out. Talked to two other furnace people and they have no clue either, other to say bad thermocoupler. WTH is wrong with this thing. Been good for years and just started this crap last November 2017.
