How to Fix / Troubleshooting

Safety: Unplug the unit before opening any panels.

  • 1. Check for overheating: Ensure all filters and air paths are clear. Allow the unit to cool for 30 minutes and see if operation improves.
  • 2. Inspect power cord and plug: Wiggle the cord and plug gently while the unit is running (if safe). If power cuts out, replace the cord.
  • 3. Test power switch: Access and test the main power switch for intermittent operation. Replace if it fails continuity tests.
  • 4. Reseat connectors: Check all internal wiring connectors, especially to the motor and control board. Reseat firmly.

Note: Frequent thermal trips indicate underlying airflow or motor issues that should be addressed promptly.
