Unit is excessively hot on the sides or top exterior surfaces.

Safety: Surfaces may be hot; avoid prolonged contact. Unplug before cleaning or opening panels.

Steps:

• Check installation: Ensure the cooler has the recommended clearance on all sides and is not built into a tight cabinet unless designed for built-in use.
• Clean condenser: Remove rear panel and clean dust from the condenser coil and fan.
• Verify fan operation: Confirm the condenser fan runs whenever the compressor is on.
• Monitor temperature: After cleaning and improving ventilation, monitor exterior temperature. Warm sides can be normal, but surfaces should not be dangerously hot.
• Professional evaluation: If overheating persists with proper airflow, a sealed system issue may be present and should be checked by a technician.
