Alarm beeps and E10 appears; refrigerator may not cool correctly; door switches and lights may behave erratically.

Safety: Disconnect power before removing control panels or working near wiring.

E10 is related to the door open/closed detection circuit.

• Identify door sensor type: Candy refrigerators may use a mechanical plunger switch in the frame or a magnetic reed sensor behind the liner.
• Check operation: Press the mechanical switch or place a magnet near the sensor area and see if the interior light turns on/off (when briefly powered for testing).
• Inspect wiring: Look around the top hinge and control panel for pinched or broken wires.
• Replace faulty switch: If the switch does not change state or shows no continuity when pressed, replace it with the correct Candy door switch or reed sensor.
• PCB input check: If the switch and wiring are good, the main PCB input circuit may be defective and require board replacement.
