Refrigerator shows E9; alarm may sound and unit may stop cooling or run erratically.

Safety first: Unplug the refrigerator before accessing the rear control compartment.

Inspect the main PCB:

• Remove the rear service cover to access the main control board.
• Look for burnt tracks, swollen capacitors, or discolored components.
• Smell for any burnt odor indicating component failure.

Check connected loads:

• Disconnect non-essential loads one at a time (e.g., defrost heater, fan motor) and inspect their wiring for shorts to ground.
• If a component is visibly shorted or its wiring is melted, replace that component before fitting a new PCB.

PCB replacement:

• Photograph all wiring connections to the PCB.
• Transfer each connector from the old board to the new Finlux main control PCB one by one.
• Ensure the board is mounted securely and protected by its cover.

Re-test: Restore power and monitor operation. The E9 code should clear if the underlying fault has been corrected.

Warning: PCB-level component repair is not recommended for untrained users. Always replace the complete board with the correct Finlux part number.
