Freezer trips the household circuit breaker or GFCI outlet when it starts or runs.

Safety: Repeated breaker tripping indicates a potential shock or fire hazard. Unplug the freezer and do not continue resetting the breaker.

• Inspect power cord: Check the entire length of the cord and plug for cuts, burns, or crushed areas. Replace the power cord if damaged.
• Check for moisture: Look for signs of water around the compressor compartment, control board, and interior light/controls. Dry any moisture and identify the source (e.g., defrost drain leak).
• Defrost heater check: A shorted defrost heater can trip breakers. With the unit unplugged, test the defrost heater for continuity to ground using a multimeter. Replace if shorted.
• Compressor test: Testing compressor windings and insulation resistance is best done by a technician. A shorted compressor usually requires replacement of the compressor or the entire freezer.
• Use proper outlet: Large freezers should be on a dedicated, properly grounded circuit. Avoid using extension cords or power strips.
• Call a technician: If you cannot identify a simple external cause, contact a qualified appliance technician for further diagnosis.
