Setup and Installation

This section outlines the general steps for replacing the motor assembly in compatible NuTone QT100 and QT110 series ventilation fans. Specific fan models may have slight variations.

Tools Required:

• Screwdriver (Phillips and/or flathead, as needed)
• Small ratcheting wrench (e.g., 5/16 inch, for tight spaces)
• Safety glasses
• Gloves

Installation Steps:

1. Disconnect Power: Locate the circuit breaker for your bathroom fan and turn off the power. Verify that the power is off by attempting to turn on the fan.
2. Remove Light Cover: Carefully pull down the light cover (if applicable) and disengage any spring clips or fasteners holding it in place. Set it aside.
3. Remove Light Bulb Housing: If your fan has a light, remove the light bulb. Then, unfasten the screws (typically 4) holding the light bulb housing and unplug it from the main fan housing.
4. Remove Existing Motor Assembly: The motor assembly is usually held by 3 screws to the fan housing. Two of these screws can often be loosened, allowing the base to slide out. Unplug the motor from the housing.
5. Detach Old Motor from Base: The motor assembly itself is attached to a metal mounting plate. There are typically 3 screws holding the motor to this plate, one of which may also secure a grounding wire. Carefully remove these screws to separate the old motor from the mounting plate. Note the orientation of the motor and wiring for reassembly.
6. Attach New Motor Assembly to Base: Position the new NuTone 0696B000 Motor Assembly onto the existing metal mounting plate. Secure it with the screws removed in the previous step, ensuring the grounding wire (if present) is reattached correctly. A small ratcheting wrench may be helpful for screws located behind the blower wheel.

7. Reinstall Motor Assembly: Plug the new motor assembly into the fan housing. Slide the mounting plate back into position and secure it with the screws.
8. Reinstall Light Bulb Housing: Reconnect the light bulb housing (if applicable) and secure it with its screws. Reinstall the light bulb.
9. Reinstall Light Cover: Reattach the light cover, ensuring it is securely fastened.
10. Restore Power: Return to the circuit breaker and restore power to the fan unit. Test the fan and light (if applicable) for proper operation.

Operation

The NuTone 0696B000 Motor Assembly is designed for continuous and reliable operation within your NuTone QT100 or QT110 series ventilation fan. Once properly installed, the fan will activate via its standard wall switch, effectively removing moisture, odors, and stale air from the room. The motor operates at 1400 RPM, providing consistent airflow.

Maintenance

Regular maintenance, primarily cleaning, is essential to ensure the longevity and optimal performance of your NuTone ventilation fan motor assembly. Dust and debris can accumulate on the blower wheel, leading to reduced efficiency and increased noise.

Cleaning the Blower Wheel:

1. Disconnect Power: Always turn off power to the fan at the circuit breaker before cleaning.
2. Remove Motor Assembly: Follow steps 1-4 from the "Setup and Installation" section to remove the motor assembly from the fan housing.
3. Detach Blower Wheel (Optional, for deep cleaning): The blower wheel is typically held by a small washer or clip on the motor shaft. Carefully remove this fastener to detach the blower wheel.
4. Clean Blower Wheel: Use a soft brush, vacuum cleaner, or a damp cloth to remove dust and debris from the blower wheel blades. For stubborn grime, the blower wheel can be soaked in warm, soapy water, then scrubbed clean and thoroughly dried before reassembly.
5. Reassemble: If detached, reattach the blower wheel to the motor shaft, ensuring the washer or clip is pushed all the way up the shaft to secure the wheel firmly against the motor assembly.
6. Reinstall Motor Assembly: Follow steps 7-10 from the "Setup and Installation" section to reinstall the motor assembly and restore power.

Troubleshooting

If you encounter issues with your NuTone 0696B000 Motor Assembly, refer to the following common problems and solutions:

• Fan is noisy or vibrating:
  • Cause: Dust accumulation on the blower wheel, loose mounting screws, or an improperly seated blower wheel.
  • Solution: Disconnect power and inspect the blower wheel for debris. Clean as described in the Maintenance section. Ensure all mounting screws for the motor assembly and the blower wheel are tightened.
• Fan is not turning on:
  • Cause: No power to the unit, faulty wall switch, or loose electrical connections.
  • Solution: Check the circuit breaker to ensure power is supplied. Test the wall switch for functionality. Disconnect power and verify all electrical connections to the motor assembly are secure.
• Reduced airflow:
  • Cause: Clogged blower wheel or obstructed ductwork.
  • Solution: Clean the blower wheel as described in the Maintenance section. Inspect the fan's ductwork for any blockages.
