Furnace Help please! Going to 11 degrees tonight!

Looking for help on our furnace. Suddenly it only blows cold air. It worked perfect a few hours ago. It is an Atwood furnace. We have plenty of propane 3/4 of a tank. I checked the manual, no trouble shooting ideas. Of course it is going down to 11 degrees tonight!!! We at least gave a space heater.

    If the cooktop is working the problem usually is the control board, igniter or the sail switch. The air stream from the blower swings the sail switch and allows propane to enter.

    Similar experience last winter with us. Controller board fried. Had to drive to Walmart and bought two electric heaters. The electric heaters turned out to be pretty handy and much quiter.

    11 degrees? Buy some extra blankets and set your comfort expectations to low.

    Good luck!

    Maybe the PP regulator has frozen. Does the stove still work fine?
    If it has frozen then try putting a light bulb under it to keep it warm.
