Luxaire Blower or Inducer Bearing Failure

Furnace produces a high-pitched whine or screech during operation.

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 blower motor bearings, Worn inducer motor bearings, Debris in blower wheel, Misaligned blower wheel

Safety: Turn off power before inspecting moving parts.

Steps to check:

Identify source: Remove the blower door and briefly run the furnace to determine if the noise comes from the indoor blower or inducer (do not bypass safety switches).
Inspect blower wheel: With power off, check for debris or rubbing against the housing. Adjust position if rubbing.

Motor bearing issues require motor or inducer replacement by a technician using Luxaire-approved assemblies.
