Troubleshooting Notes
If your motor runs hot to the touch or vibrates, typically this means that the motor needs to be replaced. There are instances where a controller may be sending a modified signal to the motor. Before replacing the motor, bench test the motor with 120 volts directly from a test cord, see if the blower still operates the same way. If the performance improves, such as less hot and no vibrations, replace your controller, otherwise replace the motor.
The exhaust blower is responsible for removing smoke from the unit and pulling combustion air into the stove. If you notice a lazy flame when your stove is burning or smell smoke, you should shut down the stove. Carefully inspect all gaskets, clean the stove/venting, and inspect the area around the combustion blower. If all gaskets are sealing properly and the stove/venting is clean, the combustion blower may need to be replaced.
