How to Fix / Troubleshooting

Safety: Turn OFF power before touching internal components.

  • Step 1 – Clean vents: Remove dust and debris from external vents with a dry cloth or vacuum.
  • Step 2 – Internal cleaning: With power OFF, open the unit and gently clean the fan blades and surrounding area.
  • Step 3 – Sensor check: Ensure the temperature sensor is properly attached to the heat sink and not hanging loose.
  • Step 4 – Firmware update: Update firmware to ensure correct fan control logic.
  • Resolution: Replace a noisy or worn internal cooling fan. If the fan still runs unnecessarily, the temperature sensor or main control board may be misreading temperature.
