Possible Causes
Blower wheel heavily clogged with dust, Blower motor bearings failing and drawing high current, Incorrect blower speed tap selected, Restricted ductwork causing high static pressure
How to Fix / Troubleshooting
Safety first: Turn OFF power before removing the blower assembly. The blower is heavy; support it properly.
- Inspect blower wheel: Remove the blower compartment door. If possible, slide out the blower assembly. Check the wheel blades for thick dust buildup. Clean with a soft brush and vacuum.
- Check motor spin: Rotate the blower wheel by hand. It should spin smoothly without grinding or wobbling. Stiff movement indicates failing bearings.
- Verify filter and ducts: Replace the furnace filter and ensure return and supply ducts are not crushed or blocked.
- Speed tap (advanced): Some Kelvinator furnaces allow blower speed selection via colored motor leads on the control board. If the blower is set to a very low speed for heating, it may overheat. Adjustments should be made by a technician following Kelvinator airflow tables.
- Replace motor if needed: If the motor overheats and trips frequently, replacement with the correct Kelvinator blower motor is recommended.
