LG Compressor Repairs
The compressor is the heart of any LG refrigerator or freezer. When it stalls, short-cycles or stops entirely, the sealed system must be diagnosed carefully before the compressor is condemned. Our independent technicians replace LG linear and reciprocating compressors and recharge the sealed system to specification. We provide independent lg compressor repairs to households and businesses across Pretoria and surrounding suburbs, including Centurion, Pretoria East, Pretoria North and the Moot. Our technicians carry the diagnostic equipment needed to fix LG LG refrigerators and freezers correctly the first time.
Symptoms
- Compressor not starting (only a click or hum)
- Compressor running hot with no cooling
- Fridge and freezer both warming
- Tripping the house breaker on start-up
- Compressor-related error code on the display
Likely causes
Linear compressor failure
Internal piston or coil wear stops the compressor from pumping refrigerant, while the fan may still run.
Inverter board failure
A failed inverter board no longer drives the linear compressor, mimicking a compressor failure.
Start relay / PTC failure
On non-inverter models, a failed start relay prevents the compressor from starting.
Sealed-system overcharge or restriction
A capillary restriction or overcharge overloads the compressor and trips thermal protection.
Diagnostic overview
We test the compressor electricals, the inverter or start-relay drive signal, and the sealed-system pressure. We confirm whether the compressor, the drive board, or a system restriction is the true cause before recommending replacement. We complete this diagnostic on-site across Pretoria, so you receive an accurate fault confirmation and a written quote before any parts are fitted.
Repair information
Where the compressor is confirmed failed, we recover the refrigerant, replace the compressor with a matched unit, replace the filter drier, evacuate the system, and weigh in the correct refrigerant charge to LG specification. All work is covered by our workmanship guarantee, and we only replace parts once the underlying fault has been confirmed.
