Heating, Air Conditioning, Fridge, HVAC/Heating not working / central air does


Hello, my center air is working however my heat does not. I have replaced the thermal cupler & gas valve. Pilot light is on. (And the theronstat works since my air works fine) any suggestions?


Your pilot may not be strong enough to engulf the top part of the thermocouple. The pilot flame needs to be strong and engulfing the top part of the thermocouple. Double check all your safety control to make sure they did not trip. Some safeties are manual resettable , some are automatic. Bypass the thermostat and jumper the R to W terminal at the furnace low voltage terminal, that will call it on for heat. Is this a standing pilot or a spark ignition pilot
