    Gravity Floor Furnace won't fire
    I have an old gravity floor furnace and the pilot light lights & stays on but, the furnace won't fire up. I replaced the thermostat and it still won't fire. I used a jumper wire on the thermostat connectors and it fires. So, does this mean the new thermostat is bad too or is there something else?

    If you jumped the two wires to the thermostat and it worked then something must be wrong with the new thermostat or you wired it wrong.

    Thanks so much for the quick answer.
    Yeah, I already checked the wiring -- heck, there are only two wires so, if one way doesn't worh the other should (far from rocket science). So, I took the $30 Honeywell back and got the $10 Hunter model and yep, she fired right up via a theromstat setting again all is well and we can now survive another California winter! :) THANKS FOR YOUR HELP!
