Hi everyone,
Both furnaces not working on my coach. The bedroom furnace keeps tripping the breaker at the furnace itself.
The second needs the motor replaced. I can't seem to break it free from the wheel, however!
Is it possible that the breaker from the bedroom furnace is tripping due to the frozen motor on the other furnace? Is the wiring all connected?
Ideas on breaking the shaft free from the fan?
Any help is appreciated, thanks!
Disconnect, electrically, the non-functioning motor, and see what happens.
Still popped the breaker. 😔
The motor has a 1/8 hex set screw holding it on. You can access it with an extra long allen in between the fins at the rear bearing. Rotate the motor to find it. It's there.
Turn both heating thermostats off and see what happens.....
The furnace that pops the breaker can you turn the fan by hand? Maybe a mud dauber built a nest that is keeping it from turning.
I removed it and it still refuses to budge!
Spray it with PB Blaster and let it soak for a few hours ....... or better yet...... overnight.
All electricity flows through the thermal relay. Two contacts for the thermostat. Two for power, one in that is always hot and one out for the furnace.
