LG Compressor Diagnostics & Replacement in Edenvale
The compressor is the heart of your LG refrigerator. In Edenvale, power surges and load-shedding cycles stress LG inverter compressors and their drive boards, causing no-cooling, continuous running or clicking symptoms. Reyds performs a full electrical and mechanical diagnostic before recommending repair or replacement — we will never replace a healthy compressor to inflate a quote.

Common Symptoms in Edenvale
- Compressor hot but not running
- Clicking sound every 1–2 minutes from the rear
- Fridge completely warm, freezer and fridge both above safe range
- Inverter board flashing a fault LED
- Burning smell from the compressor compartment
What Causes This Fault
- Inverter board failed (no drive voltage to compressor)
- Compressor start device / PTC failed
- Compressor winding open or shorted
- Compressor mechanical seizure (valve failure)
- Damage from repeated power surges / load-shedding
Our Repair Process
- 01Measure compressor winding resistance (C-R, C-S, R-S)
- 02Test inverter output and fault LED state
- 03Check start device / PTC and run capacitor
- 04Confirm compressor failure vs inverter failure
- 05Replace with an LG-compatible compressor and re-charge to spec
- 06Leak-test and verify full temperature recovery
When to Call a Technician
A clicking, hot or silent compressor usually means the inverter or the compressor itself has failed. Switch the fridge off to prevent further damage and book a diagnostic.
Frequently Asked Questions
Is it the compressor or the inverter board?
They share symptoms. We measure the inverter's output voltage and the compressor's winding resistance — that tells us exactly which part has failed before any replacement is quoted.
Should I repair or replace an older LG fridge with a failed compressor?
If your LG fridge is under ~7 years old and otherwise sound, a compressor replacement is usually economical. On much older units we'll give you an honest comparison against replacement.
Do Johannesburg power surges cause compressor failure?
Yes. Repeated load-shedding and surges stress the inverter board and compressor windings. We recommend a surge protector once the repair is complete.
