Refrigerator display shows E0 and interior light may flash; unit may not cool correctly.

Safety first: Unplug the refrigerator from the mains before removing any panels or touching wiring. If you are not confident working with electrics, contact a qualified technician.

Step-by-step checks:

• Power reset: Unplug the fridge for 5–10 minutes, then plug back in. Sometimes E0 is a temporary communication glitch after a power surge.
• Inspect main PCB area: On most Finlux refrigerators, the main control PCB is located at the rear behind a metal or plastic cover near the compressor. Remove the cover and visually inspect the board for burn marks, swollen capacitors, or a burnt smell.
• Check wiring harnesses: Gently tug each plug going into the PCB (especially those labeled for sensors or with multi-core cables). Ensure they are fully seated and not corroded. Reseat each connector once.
• Check for moisture: Look for signs of condensation or water ingress around the PCB and connectors. Dry carefully with a cloth and allow to air dry before reassembly.
• Re-test: Refit the cover, plug the unit back in, and monitor if E0 returns. If the error persists, the PCB or a connected sensor circuit is likely faulty.

When to call a professional: If you find burnt components on the PCB or the error returns immediately after reset, replacement of the main control board and/or sensor harness is recommended and should be done by a technician.
