Safety Checks You Can Do

Steps you can try at home safely

• Check your home's circuit breaker and ensure the refrigerator's breaker switch is in the ON position • Verify both the refrigerator and freezer doors are fully closed and sealing properly with no gaps • Confirm temperature settings are adjusted to recommended levels (typically 37-40°F for refrigerator, 0°F for freezer) • Inspect visible air vents inside the refrigerator and freezer for any blockages from food items or debris • Unplug the refrigerator from the wall outlet or turn off its dedicated circuit breaker for 60 seconds, then restore power to attempt a reset • Check that the refrigerator has adequate clearance on all sides (at least 1 inch) and ensure air can circulate freely around the unit • If accessible without disassembly, gently clean the condenser coils located at the back or bottom of the refrigerator using a soft brush to remove dust and debris • Ensure the refrigerator is not placed directly against a wall or in an enclosed space that restricts air circulation
