Ignis dE

Ignis error code DE indicates: Ignis Combi Double Door Total NoFrost Refrigerator: Defrost circuit failure dE; electric heating element failed to warm evaporator coil sufficiently during scheduled defrost cycle..

The primary root cause for Ignis code DE is: On Ignis refrigerators (Ignis heavy-duty electromechanical chassis and Arcadia / L1373 hybrid control architecture): Open-circuit calrod heating element (~160 Ω to 260 Ω), blown in-line thermal fuse (72°C), or stuck defrost relay contacts on PCB..

To resolve error code DE: Disconnect mains. Remove freezer evaporator cover. Measure defrost heater resistance (~160–260 Ω) and thermal fuse continuity (<1 Ω). Replace defective component. Press thermostat reset or super button for 3 seconds to cancel temperature alarm and re-arm cooling.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ignis code DE persists, the physical component causing On Ignis refrigerators (Ignis heavy-duty electromechanical chassis and Arcadia / L1373 hybrid control architecture): Open-circuit calrod heating element (~160 Ω to 260 Ω), blown in-line thermal fuse (72°C), or stuck defrost relay contacts on PCB. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
