What to do if my Pro-Fab Industries Furnace damper does not open?
- JJohn MartinAug 17, 2025
If the damper on your Pro-Fab Industries Furnace isn't opening, there could be several reasons. First, the high limit switches might be off because the water temperature is too high; in this case, wait for the water to cool down. Second, the circuit breaker may have disengaged because of creosote buildup, so clean the damper area and push the reset button on the breaker. Also, check your power supply. Finally, the damper solenoid might be defective and need replacement.
