I have an older trailor that has a miller furnace with a wayne burner.My problem is that the furnace will run fine but I cant adjust the thermostat I've replaced the thermostat but it still runs nonstop.Does anyone know what else it could be If you can help Id appreciate it. Thanks

Disconnect the thermostat, turn the power on to the furnace. if the heat still comes on, you have a short or bad control.

If it doesn't come on. You may have a short in the wires when you mount the stat, make sure wires are insulated and not touching..
