2010 Atwood Furnace

[2flyfish]

Hoping someone here can help. At about 4:30 this morning we noticed that our furnace was blowing cold air. It's windy and raining out. Decided to just turn it off and try to deal with it in the daylight. We slid the switch to the off position on the Duo-Therm wall thermostat but the fan is still running. It's been an hour and it hasn't shut off. We have been searching manuals and the MOC forum looking for any info.
If anyone can help we would sure appreciate it. Thanks!!!!

Go to the search function on the right above and use reset thermostat as the search title and you'll get a lot of answers to all the things that could be wrong. First I'd check the tanks to make sure the gas is on from both tanks and not empty. Second I'd reset the thermostat which on your model, I believe, involves turning it off, holding the mode and zone buttons at the same time while turning it back on. It should then display FF, after two seconds release the buttons and it should be reset. After that it gets more complicated.
