Safety Checks You Can Do

Steps you can try at home safely

• Check that the circuit breaker supplying the refrigerator is in the ON position; if tripped, reset it and monitor for recurrence • Ensure both refrigerator doors are closing completely and sealing properly with no obstructions • Verify temperature settings are appropriate (typically 35-38°F for fresh food section) • Inspect visible air vents inside the fresh food compartment to confirm they are not blocked by food items • Unplug the refrigerator from the wall outlet or turn off its dedicated circuit breaker for 60 seconds, then restore power to perform a complete system reset • Check that the refrigerator has adequate clearance on all sides (minimum 1 inch on sides and back) to ensure proper airflow and cooling • If accessible without disassembly, gently vacuum the condenser coils located at the bottom or back of the unit to remove dust and debris • Listen for normal compressor operation and fan sounds indicating the cooling system is attempting to function
