3. Installation Guide
This section outlines the general steps for replacing the heat motor assembly. Specific procedures may vary slightly depending on your exact Nutone heater model. Refer to your original heater unit's manual for detailed disassembly and reassembly instructions.
3.1 Tools Required
- Screwdriver (Phillips and/or flathead, as needed)
- Wire strippers/cutters
- Wire nuts or electrical connectors
- Voltage tester
- Work gloves
- Safety glasses
3.2 Replacement Steps
- Disconnect Power: Locate the circuit breaker or fuse that supplies power to the heater unit and turn it OFF. Use a voltage tester to confirm that power is completely disconnected at the unit.
- Access the Heater Unit: Carefully remove the grille or cover of your Nutone heater unit to expose the internal components. This may involve unscrewing fasteners or releasing clips.
- Remove Old Motor Assembly: Disconnect the electrical wires from the old motor assembly. Note the wiring configuration for correct reinstallation. Unscrew or unclip the old motor assembly from its mounting bracket or housing. Carefully remove the old unit.
- Prepare New Motor Assembly: The new Nutone 69355000 assembly comes with the motor, mount, and blower wheel pre-assembled. Ensure the blower wheel is securely attached to the motor shaft.
- Install New Motor Assembly: Position the new motor assembly into the heater unit's housing, aligning it with the mounting points. Secure it with the appropriate screws or clips, ensuring it is firmly in place and does not wobble.
- Connect Wiring: Connect the electrical wires from the heater unit to the new motor assembly. Use wire nuts or appropriate electrical connectors to ensure secure and insulated connections. Match the wiring configuration noted during removal of the old unit.
- Reassemble Unit: Carefully replace the grille or cover of the heater unit, ensuring all fasteners are tightened and the cover is securely in place.
- Restore Power and Test: Turn the power back ON at the circuit breaker or fuse box. Test the heater unit to ensure the new motor assembly operates correctly, providing heat and proper airflow. Listen for any unusual noises.
4. Operation
The Nutone 69355000 Replacement Heat Motor Assembly functions as the core component for circulating heated air within your compatible Nutone heater unit. Once properly installed, its operation is controlled by the existing switches and thermostat of your heater unit. When the heater is activated, the motor drives the blower wheel, drawing in cool air, passing it over the heating element (if applicable to your unit), and expelling warm air into the room.
5. Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your heater unit and its motor assembly.
- Power Disconnection: Always disconnect power to the unit before performing any maintenance.
- Cleaning: Periodically remove the heater grille and gently clean the blower wheel and motor housing with a soft brush or vacuum cleaner to remove dust and debris. Accumulation of dust can reduce efficiency and cause overheating.
- Inspection: Annually inspect the motor assembly for any signs of wear, loose connections, or unusual vibrations. Ensure the blower wheel spins freely without obstruction.
- Lubrication: This motor assembly is typically sealed and does not require lubrication. Do not attempt to lubricate the motor unless specifically instructed by the manufacturer of your heater unit.
6. Troubleshooting
If your heater unit is not functioning correctly after installing the replacement motor assembly, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater unit does not turn on. | No power to the unit. Loose or incorrect wiring connections. Faulty wall switch or thermostat. | Check circuit breaker/fuse. Ensure power is restored. Verify all wiring connections are secure and correct (power OFF). Test wall switch/thermostat for functionality. |
| Motor runs but no air or weak airflow. | Blower wheel obstructed or loose. Excessive dust/debris on blower wheel. | Disconnect power. Inspect blower wheel for obstructions and ensure it is securely attached to the motor shaft. Disconnect power. Clean blower wheel and housing thoroughly. |
| Unusual noise (e.g., grinding, squealing). | Blower wheel rubbing against housing. Motor bearing issue. Loose mounting screws. | Disconnect power. Inspect blower wheel for proper clearance. Adjust if possible. If noise persists after checking for obstructions, the motor may be faulty. Contact support. Disconnect power. Ensure all mounting screws are tight. |
| Heater unit overheats and shuts off. | Restricted airflow due to dust/debris. Overload protector tripped. | Disconnect power. Clean blower wheel and air passages. Ensure proper ventilation. Allow unit to cool down. If it trips frequently, investigate airflow issues or consult a professional. |
If troubleshooting steps do not resolve the issue, it is recommended to consult a qualified electrician or HVAC technician.
