Customer Question

My furnace fan comes in for a few seconds, and shuts off. No heat. It was working fine 3 weeks ago. I just put a full tank in and the water heater and stove work fine. It's 27 here and any help would be appreciated

Hi my name is Robert....

After the fan comes on can you hear the furnace comes on can you hear it sparking at all? You should hear a click from the gas valve and at the same time the electrode should spark... Very important to know if it is sparking or not... Robert
