Rug Doctor carpet cleaner makes a high-pitched whine or screech from the motor area, especially under load.

Safety: Unplug the unit before accessing the motor compartment.

• 1. Check for clogs: Before assuming motor failure, ensure all filters, hoses, and intake ports are clear to reduce load on the motor.
• 2. Inspect motor fan area: Remove the motor cover and check for debris in the motor fan housing. Carefully remove any foreign objects.
• 3. Assess bearing noise: Spin the motor shaft by hand (if accessible). Roughness or grinding indicates worn bearings. The vacuum motor assembly should be replaced; bearing replacement alone is typically not cost-effective.
• 4. Check mounting: Ensure the motor mounting screws and rubber isolators are intact and tight.

Note: Operating with failing bearings can lead to motor seizure and potential electrical damage.
