TCA37071520 Genuine LG Fridge Compressor, LG Refrigeration Compressor Replacement for Sealed System Repairs

TCA37071520 is a genuine LG compressor, the motor-driven pump at the heart of the refrigeration system. LG has many close variants under its TCA numbers, such as TCA37071511, so the number must match exactly. This is a sealed system part, and in Australia it can only be fitted by a technician who holds a refrigerant handling licence.

LG fridge not cooling? When the compressor is the culprit

The compressor pumps refrigerant around the sealed system, squeezing it into a hot, high-pressure gas that sheds heat through the condenser before it expands and draws heat out of the cabinet. When it fails, the fridge warms up even though the light and fans work, the compressor may click on and off without starting, hum loudly, or run constantly while the cabinet stays warm. A cooling fault isn't always the compressor itself. Start relays, inverter boards, a blocked system or a gas leak can all look similar, so a proper diagnosis comes first.

Installation by a licensed technician

Replacing a compressor means recovering the refrigerant, brazing the new compressor in, fitting a new filter drier, pulling a vacuum and recharging to the maker's specification. It must be done by a technician with an ARC refrigerant handling licence, and the electrical side by someone qualified for mains work. Always isolate the fridge at the power point before any work starts.

Questions about this part

Can I fit this compressor myself?

No. In Australia, any work that opens a refrigeration system must be done by a technician holding a refrigerant handling licence from the Australian Refrigeration Council. They will recover the old gas, fit the compressor and recharge the system correctly.
