TCA37032031 Genuine LG Fridge Compressor Set Assembly, Refrigeration Compressor for LG Fridges

TCA37032031 is a genuine LG compressor set assembly, the pump at the heart of a fridge's sealed cooling system. We couldn't find a published model list for this number, so match it to the part number on your old compressor or to the quote from your refrigeration technician. Swapping a compressor means opening the sealed refrigerant system, so it's strictly a job for a licensed technician.

Fridge not cooling? When the compressor is the problem

The compressor pumps refrigerant around the sealed system, squeezing it so it can shed heat at the back of the fridge and then absorb heat inside the cabinet. When it fails, both the fridge and freezer warm up even though the lights and fans may still run. Other signs are a compressor that clicks on and off without starting, a loud hum or knock, or a compressor that's hot but not pumping. Before condemning it, a technician will usually check the start components, the control board and the refrigerant charge, since those faults can look much the same.

Who can fit a fridge compressor

In Australia, anyone opening a refrigerant system must hold a refrigerant handling licence, so this part has to be fitted by a licensed refrigeration technician. The job involves recovering the old gas, brazing in the new compressor, replacing the filter drier, pulling a vacuum and recharging. Switch the fridge off at the wall and move food to another fridge before the tech arrives.

Questions about this part

Can I fit this compressor myself?

No. Fitting a compressor means opening the sealed refrigerant system, and Australian rules require a licensed refrigeration technician for that work. They also have the equipment to recover and recharge the gas correctly.
