Safety Checks You Can Do

Steps you can try at home safely

• Check your home's circuit breaker panel and ensure the refrigerator's dedicated circuit breaker is in the ON position; flip it OFF then back ON if tripped • Verify all refrigerator door seals are clean and doors close completely with a firm click • Confirm temperature settings are appropriate (refrigerator 35-38°F, freezer 0°F or below) • Remove any items blocking air vents inside both compartments to ensure proper airflow • Inspect the condenser coils at the back or bottom of the refrigerator for dust and debris; gently vacuum them with a soft brush attachment if accessible • Ensure adequate clearance around the refrigerator (at least 1 inch on sides, 1 inch on top, 4-6 inches at back) for proper ventilation • Unplug the refrigerator from the wall outlet for 60 seconds, then plug it back in to perform a soft reset; alternatively, turn off the circuit breaker for 60 seconds then turn back on • Check that the refrigerator is level by using a spirit level; adjust the front leveling feet if needed as improper leveling can affect cooling performance • Verify that your home's electrical outlet is functioning by plugging in another appliance to confirm power delivery
