Possible Causes
Failed fan motor, Seized fan bearings, Loose or damaged fan wiring, Faulty fan driver circuit on control board
How to Fix / Troubleshooting
Safety first: Turn OFF power and gas. Fan and combustion components can be sharp—wear gloves.
- Check fan movement: Remove the front cover and gently spin the combustion fan wheel by hand. If it is stiff or seized, the blower assembly must be replaced.
- Inspect wiring: Verify that the fan motor connector is fully seated and that wires are not pinched or burnt.
- Power check (advanced): With power ON and a hot water tap open (only if qualified), measure voltage at the fan connector. If no voltage is present, the control board may be faulty.
- Replace blower: If the fan is seized or noisy, replace the combustion blower assembly with a Richmond-approved part. Ensure gaskets are properly seated to prevent flue gas leaks.
- Control board replacement: If the fan is good but not receiving power, have a technician replace the main control board.
