If the venter motor on your Reznor Gas Heater won't start, here are a few things to check: 1. Make sure the unit has power and check the supply fuses or circuit breaker. 2. Ensure the thermostat is turned up to provide 24V power to the integrated circuit board. 3. Check the control transformer output. 4. Replace the integrated circuit board fuse (3A, type ATC or ATO, 32VDC) after fixing the cause of the blown fuse. 5. Tighten connections at the circuit board and/or motor terminals to ensure power is reaching the venter motor. 6. If the integrated circuit board is defective, replace it. 7. If the venter motor is defective, replace it, referring to the Venter Motor and Wheel Assembly Maintenance section.
