Display shows E5; refrigerator may not defrost properly or may over-defrost, causing temperature swings.

Safety: Unplug the refrigerator. Be cautious of sharp metal edges and residual ice.

E5 indicates the control board detects a problem in the defrost heater circuit.

• Access the evaporator area: Remove freezer drawers and the rear inner panel to expose the evaporator and defrost heater.
• Visual inspection: Look for burnt spots on the heater, melted insulation, or a tripped thermal fuse attached to the evaporator tubing.
• Test heater resistance: Disconnect heater connectors and measure resistance with a multimeter. Typical Candy defrost heaters read between 50–300 Ω. Infinite resistance means the heater is open and must be replaced.
• Check thermal fuse/thermostat: Test continuity across the defrost thermal fuse or bimetal thermostat. If open at room temperature, replace with the correct Candy-rated part.
• Inspect wiring: Check for broken or burnt wires from heater to PCB.
• PCB evaluation: If heater and safety devices are good, the defrost relay or triac on the main PCB may be defective. Replacement of the board is recommended by a professional.
