Possible Causes

How to Fix / Troubleshooting

Safety first: Unplug the unit before inspection.

  • Check ventilation: Ensure all vents are clear and the unit is not enclosed in a tight cabinet.
  • Inspect power cord: Look for damage and ensure the plug fits snugly in the outlet. Try a different outlet to rule out a loose receptacle.
  • Clean internal dust: Remove the rear/bottom panel and gently vacuum dust from the control board and fan area to improve cooling.
  • Observe behavior: After reassembly, run the unit and note if it shuts off when the compressor gets hot. This may indicate a failing thermal protector or power supply on the board.
  • Next step: If the unit continues to shut off without codes, replacement of the main control board is often required.
