Possible Causes
Seized or worn fan motor bearings, Obstruction in fan wheel, Faulty fan speed sensor, PCB fan driver failure
How to Fix / Troubleshooting
Safety first: Turn OFF power and gas. Wait until all moving parts have stopped.
Steps to check and correct:
- Check for obstructions: Remove the front cover and inspect the combustion fan wheel for debris or foreign objects. Remove any blockage.
- Spin test: Gently spin the fan by hand. If it does not rotate freely or feels rough, the motor is likely failing and should be replaced.
- Inspect wiring: Verify that the fan motor connector and speed feedback wires are secure and undamaged.
- Reset and test: Restore power and run the unit. If error 61 persists, the fan motor or PCB must be replaced by a qualified technician.
