Specialist Defrost System restoration for LG refrigeration in Big Bay. The defrost system commonly fails through heater open-circuit, bimetal disc, or defrost sensor drift. We carry matched OEM-spec defrost system modules and the diagnostic rig to validate the repair on-site — 55-minute average arrival.
Our Big Bay callout begins with a full Linear Compressor handshake diagnostic — reading the inverter drive signal, validating PCB relay states, and mapping every temperature sensor against OEM specification. Because Big Bay sits on the Table Bay coastline, we additionally profile the unit for salt-air PCB corrosion and accelerated defrost-heater fatigue.
