My furnace pilot light keeps going out. The furnace will come on and heat up to the degree set on my thermostat, then the pilot goes out and the furnace will not come back on. Could the thermostat be bad and cause the pilot light to go out? Is there anyway for me to check the problem myself?

The thermocouple that verifies that the pilot light is burning (as opposed to releasing unburned gas) could be going bad. And you could also have either a blockage in your flue or a high temperature limit switch that detects or triggers a false positive that there's too much heat building up in your flue and shuts off the gas for safety. And finally, there could be a blockage in your pilot light itself that prevents it from properly working. The first thing I would try replacing is the thermocouple. |
