• Verify the refrigerator is plugged into a working 120V outlet and check that the outlet has power using another appliance• Inspect your home's circuit breaker panel to ensure the refrigerator's circuit breaker is in the ON position; reset it by switching OFF then ON if tripped• Ensure the refrigerator's ventilation openings (rear coils and side vents) are not blocked by dust, debris, or objects; gently vacuum accessible areas• Check that both the refrigerator and freezer doors close completely and seal properly without gaps; inspect door gaskets for damage or debris• Verify temperature control settings are appropriate (typically 37-40°F for fridge, 0°F for freezer) and adjust if needed• Perform a complete power reset by switching off the circuit breaker for 60 seconds, then switch back ON to allow the control system to reinitialize• Look for any visible loose wires or disconnected connectors near the temperature control panel if safely accessible• Clean the condenser coils located at the bottom rear of the refrigerator using a soft brush or vacuum if you can access them safely• Check for excessive frost or ice buildup in the freezer compartment and allow the refrigerator to defrost if necessary
