Help Furnace Will not shut off

[Bruceh]

Just got back to our 2006 Classic 30'. The problem is i had set the heat on 45 and when i returned i changed to 69. The problem then started the temp kept going up. Not sure how hot it got before i turned the gas off. That was the only way that i could shut the furnace off. The controlls on the thermastate would not work for the furnace. At that point i turnrd the heat pump on and everything works fine. The problem is only with the furnace. Has anyone else had this same problem or an idea as to what the problem is?
Thanks

Sounds like a circuit board let go. If your trailer is still under warranty, take it back for repairs.

Bruce,

Sounds like your thermostat is defective.....and should be replaced. If you need heat, I would remove the t/stat from the wall and disconnect the 2 blue wires coming from it. These are the control wires that lead to the furnace. They can be joined together to operate the furnace, and then seperated to turn it off. Please note that this is applicable for an analog t/stat ONLY!

If you have a Dometic digital Comfort Control Center (which also operates your air conditioner), the process is more involved. PM me if this is the case!
