Refrigerator exterior side walls or door edges feel very hot to the touch

Safety first: Unplug the refrigerator before cleaning coils or accessing the rear compartment.

Steps:

• Clean condenser: Use a brush and vacuum to remove dust from coils at the back or underneath.
• Check fan operation: Ensure the condenser fan runs when the compressor is on. Replace the fan motor if it does not run and wiring is intact.
• Improve airflow: Move the refrigerator slightly away from the wall and ensure top and sides have the recommended clearance.
• Monitor: After cleaning and improving ventilation, the exterior should still be warm but not excessively hot. If it remains very hot, have a technician check for sealed system issues.

Note: Some warmth on door edges is normal; they often contain anti-condensation heaters or condenser loops.
