Setup and Installation
Installation of this motor should only be performed by a certified HVAC professional.
- Power Disconnection: Locate the main electrical disconnect for the furnace and turn it OFF. Verify power is off using a voltage tester.
- Access Blower Compartment: Remove the furnace access panels to expose the blower assembly.
- Disconnect Wiring: Carefully label and disconnect all electrical wiring from the old blower motor. Take photos for reference if necessary.
- Remove Old Motor: Unbolt or unclamp the old motor from its mounting bracket. Carefully slide the motor out of the blower housing. Note the orientation of the motor and blower wheel.
- Transfer Blower Wheel: If the new motor does not come with a blower wheel, carefully remove the blower wheel from the shaft of the old motor. Clean the blower wheel thoroughly. Install the blower wheel onto the shaft of the new motor, ensuring it is properly aligned and secured.
- Install New Motor: Insert the new Lennox 10064911 motor into the blower housing, ensuring proper alignment with the blower wheel. Secure the motor to its mounting bracket.
- Reconnect Wiring: Reconnect all electrical wiring to the new motor, matching the labels or referring to your reference photos and the furnace wiring diagram.
- Secure Panels: Replace all furnace access panels.
- Restore Power: Turn the main electrical disconnect for the furnace back ON.
- Test Operation: Initiate a heating or cooling cycle to ensure the new blower motor operates correctly, quietly, and moves air effectively.
Operating Instructions
As a replacement component, the Lennox 10064911 blower motor's operation is controlled by the furnace's thermostat and control board. Once properly installed, the motor will engage automatically when the furnace calls for heating or cooling, or when the fan is set to continuous operation via the thermostat.
- Ensure your thermostat is set to the desired mode (Heat, Cool, or Fan ON).
- Listen for smooth operation and proper airflow from your vents.
Maintenance
Regular maintenance of your furnace system, including the blower motor, is crucial for longevity and efficiency. While the motor itself is generally maintenance-free, consider the following:
- Air Filter Replacement: Regularly replace or clean your furnace's air filter according to the manufacturer's recommendations. A dirty filter restricts airflow, causing the blower motor to work harder and potentially overheat.
- Blower Wheel Cleaning: Periodically inspect the blower wheel for dirt and debris buildup. A dirty blower wheel can become unbalanced, leading to noise and reduced airflow. Cleaning should be performed by a qualified technician.
- Professional Inspection: Schedule annual professional HVAC inspections to ensure all components, including the blower motor, are functioning optimally.
Troubleshooting
If you experience issues after installing the new blower motor, consider the following common problems and potential solutions. Always disconnect power before inspecting any internal components.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power, incorrect wiring, faulty capacitor (if applicable), motor overload. | Check circuit breaker. Verify wiring connections. Consult a technician to test capacitor or motor. |
| Motor runs but no airflow | Blower wheel loose on shaft, obstructed ducts, dirty air filter. | Ensure blower wheel is securely fastened. Check and replace air filter. Inspect ducts for blockages. |
| Unusual noise from motor | Loose mounting, unbalanced blower wheel, worn bearings (unlikely for new motor), debris in blower housing. | Check motor mounting. Inspect blower wheel for dirt or damage. Contact a technician for further diagnosis. |
If troubleshooting steps do not resolve the issue, contact a qualified HVAC technician for professional assistance.
