Unit trips the household circuit breaker when plugged in or when compressor starts.

Safety warning: Repeated breaker tripping indicates a potentially dangerous fault. Do not repeatedly reset the breaker without inspection.

• Inspect power cord: Unplug the unit and check the cord for cuts, burns, or crushed sections. Replace the power cord assembly if damaged.
• Check for moisture: Look for signs of water around the rear panel, compressor area, and control board. Dry thoroughly and correct any leaks before reapplying power.
• Isolate components: With the unit unplugged, disconnect the compressor harness from the main board. Plug the unit in; if the breaker no longer trips, the compressor or its wiring is suspect and requires professional service.
• Main board inspection: If the breaker trips even with the compressor disconnected, the main control board or internal wiring may be shorted. Replace the main control board or damaged harness as needed.
• Professional help: If you are not experienced with electrical diagnostics, contact a qualified technician.
