Safety Checks You Can Do

Steps you can try at home safely

• Check your home's circuit breaker panel and verify the breaker serving the refrigerator is in the ON position; if tripped, switch it OFF then back ON • Inspect the power cord at the back of the refrigerator for visible damage, cuts, or wear • Ensure the power plug is fully inserted into the wall outlet with no gaps • Try plugging a different appliance (like a lamp) into the same outlet to verify the outlet is providing power • Verify the refrigerator is plugged directly into a wall outlet and not using an extension cord or power strip • Confirm the outlet is a dedicated, grounded 115V outlet suitable for major appliances • Close all refrigerator and freezer doors completely and listen for the compressor attempting to run • Check that nothing is blocking airflow around the refrigerator; maintain 2 inches clearance on sides and back • Perform a hard reset by unplugging the refrigerator from the outlet for 60 seconds, then plugging it back in • Alternatively, turn OFF the circuit breaker serving the refrigerator for 60 seconds, then turn it back ON • Wait 5 minutes after power restoration for the control board to fully initialize • Verify interior temperature settings are appropriate (typically 37°F for refrigerator, 0°F for freezer)
