I have a natural gas furnace that won't stay on. The pilot is lit and the burners come on, a few seconds later the fan starts and runs for no more than a minute and then it stops. The burners sometimes go out before the fan stops or the fan never comes on at all. I can turn the fan on at the control and have it run with out a problem, but that is just circulating the air and not heating it. I think the fan is controlled by it's own thermostat. Once the thermostat in the house starts the burners a thermostat in the furnace turns on the fan when it reaches a certain temp to blow the warm air through the ducts. Does this sound right? Could this be where my problem lies? Could it be as simple as a loose wire to that particular thermostat? We had a service guy come and look at it and tell it us it's just old & inefficient and it'll be about a grand to replace. I had the Gas Company out last week to replace my meter with a higher flow model due to a recent swimming pool installation. He checked all our gas appliances after the replacement and everything including the furnace worked fine. The furnace started having trouble over a week later, I doubt the problem was caused or triggered by anything he did since the furnace worked fine for over a week. Help a cold Californian please, yes it gets cold in CA. I'm in SoCal, high desert area, last weekend we had single digit temps (rare). Thank God it worked then.
