Tappan Failing Inducer Motor Bearings

Furnace inducer motor is very loud or grinding.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn bearings in Tappan inducer assembly, debris in inducer wheel, misaligned inducer housing

Safety: Turn off power and gas before servicing the inducer.

Steps:

Remove the inducer housing cover if accessible and inspect for debris in the wheel. Remove any obstructions.
Spin the inducer wheel by hand. If it feels rough or wobbly, the motor bearings are likely failing.
Replace the inducer motor assembly with an OEM Tappan-compatible unit, transferring gaskets and ensuring a proper seal to the heat exchanger.
After replacement, verify quiet operation and proper pressure switch function.
