Buyer's checklist
What to check before buying a used blower motor
- Distinguish between automatic climate control motors (often equipped with integrated control modules) and standard manual HVAC blower motors.
- Spin the squirrel cage fan by hand to check for worn bearings, ticking noises, or off-center wobble that causes excessive noise and premature failure.
- Check the condition of the electrical pigtail and terminal pins for heat discoloration, melting, or corrosion caused by high amperage draw.
- Verify mounting hole orientation and cage depth, as trim levels or different HVAC box suppliers within the same model line can use non-interchangeable designs.
