This section outlines the general steps for replacing an existing motor assembly. Specific procedures may vary slightly depending on your exact NuTone model. Refer to your original unit's manual for detailed housing removal instructions if necessary.

5.1. Tools Required

• Screwdriver (Phillips and/or Flathead)
• Pliers (optional, for wire connections)
• Wire strippers (if new wire connections are needed)
• Safety glasses and gloves

5.2. Installation Steps

1. Disconnect Power: Locate the circuit breaker or fuse box that controls power to the fan/heater unit. Turn off the power completely and verify it is off before proceeding.
2. Access the Unit: Remove the grille cover from your NuTone unit. This usually involves pulling down on the cover and squeezing spring clips, or unscrewing retaining screws.
3. Remove Old Motor Assembly:
   • Locate the screws or clips holding the old motor assembly in place.
   • Carefully disconnect any electrical wires connected to the motor. Note their positions for re-connection.
   • Remove the old motor assembly from the housing.
4. Inspect and Prepare New Assembly:
   • Examine the new S89222000 motor assembly for any shipping damage.
   • Important Note: Some users have reported that the fan blade (squirrel cage) on new assemblies may be slightly warped or misaligned, potentially causing rubbing or noise. If this occurs, you may need to carefully adjust the fan blade's position on the motor shaft or consider reusing the original fan blade if it is in good condition and compatible. The fan blade is typically pressure-fit onto the shaft.
   • Bracket Fit: The mounting bracket may sometimes require minor adjustments or reuse of the original bracket for optimal fit within older housings.
5. Install New Motor Assembly:
   • Position the new motor assembly into the unit's housing, ensuring the mounting bracket aligns with the existing screw holes or clips.
   • Secure the motor assembly with the appropriate screws or clips. Ensure it is firmly seated and does not wobble.
   • Connect the electrical wires to the new motor assembly, matching the connections noted during removal. Ensure all connections are tight and secure.
6. Test Operation: Before reattaching the grille, temporarily restore power at the service panel. Turn on the fan/heater unit to ensure the motor operates smoothly and quietly. Check for any unusual noises or vibrations. If issues arise, refer to the Troubleshooting section.
7. Restore Unit: Once satisfied with the operation, disconnect power again at the service panel. Reattach the grille cover securely. Restore power permanently.

6. Operating Instructions

Ensure the unit's power is on and the controls are set correctly for desired operation (e.g., fan on, heater on).
