LG PCB / Control Board Repair — Isando

When the pcb / control board on your LG appliance in Isando fails, the whole cooling chain stops. The main PCB (control board) governs the defrost cycle, compressor drive, fan outputs and sensor logic. PCB faults can mimic almost any other failure — which is why we always test the sensors and actuators the board drives before condemning the board itself.

PCB / Control Board Diagnostics

The main PCB (control board) governs the defrost cycle, compressor drive, fan outputs and sensor logic. PCB faults can mimic almost any other failure — which is why we always test the sensors and actuators the board drives before condemning the board itself.

Diagnostic Steps

  • Read any fault code from the display
  • Test all sensors the board reads (cabinet, freezer, defrost)
  • Verify board outputs to compressor, fans and defrost heater
  • Inspect the board for burnt tracks or swollen capacitors
  • Confirm supply voltage to the board

Common Failures

  • Burnt PCB tracks
  • Failed relay on the board
  • Swollen capacitors
  • Corrupted defrost logic
  • Board not driving outputs

Frequently Asked Questions

Can the pcb / control board on my LG appliance be repaired, or does it need replacing?

Most can be repaired or replaced at component level. We test before quoting so you only pay for the part that's actually failed.

How long does a pcb repair take?

Most component repairs are completed in a single visit once the part is confirmed. We carry common LG components to minimise call-backs.
