The LG Compressor: a technical dossier
The compressor is the heart of your LG fridge — it pumps refrigerant through the cooling loop. LG uses Linear Inverter Compressors in modern models, which run quieter and more efficiently but require specialist inverter-board diagnostics before replacement.
- Compressor won't start — clicks then stops
- Fridge runs continuously but doesn't cool
- Loud knocking or humming from the back
- Inverter board error code displayed
- Overheating and tripping the power
- Test the inverter PCB output to the compressor
- Measure compressor winding resistance and start current
- Check refrigerant charge and system pressures
- Replace with a genuine LG Linear or inverter compressor
- Vacuum, regas and leak-test the system
