Heater Stuck On - 1996 Road Ranger 5th Wheel
The motor to the heater in our 5th wheel will not turn off with the thermostat all the way down and off. I pushed the thermostat up to engage blower and make sure the heater will still produce warm air and it did.
Then turned the thermostat back down- the blower turned off but there is still a hum coming from the heater below the refrigerator.
I then went through my breaker box, nothing a miss there.
Any ideas, suggestions??
