Furnace Problems? Part 2
Than I will say I have to feel for you tonight. You need to replace the gas valve. I would reccomend a Robertshaw gas valve if they are available in your area. I believe the one you would need is a 720-402 if your burner manifold is 1/2" or if it is 3/4" you will need a 720-502. Either way, I wish I had better news for you. I now myself have about 1 1/2' of snow in my town. Let me know if I can help you any further, one question before I go. When they sold you the fan limit switch did they tell you to break out the tab in the bottom center of the new switch. If they didn't or you fogot to, you just ran 120 volt through a 24 volt gas valve and thermostat. If this happened you may end up replacing the thermostat also.
