Ignis AL01

Ignis error code AL01 indicates: Ignis Combi Double Door Total NoFrost Refrigerator: Fresh food compartment evaporator NTC thermistor sensor fault AL01; circuit reading out of calibrated limits..

The primary root cause for Ignis code AL01 is: On Ignis refrigerators (Ignis heavy-duty electromechanical chassis and Arcadia / L1373 hybrid control architecture): Water ingress into thermal sensor epoxy potting, fractured copper leads behind liner, or corrosion on terminal pin J1..

To resolve error code AL01: Unplug unit. Access sensor behind rear baffle. Measure NTC resistance: nominal ~2.7 kΩ at 25°C, ~7.8 kΩ at 4°C, ~16 kΩ at 0°C. Replace sensor probe. 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 AL01 persists, the physical component causing On Ignis refrigerators (Ignis heavy-duty electromechanical chassis and Arcadia / L1373 hybrid control architecture): Water ingress into thermal sensor epoxy potting, fractured copper leads behind liner, or corrosion on terminal pin J1. 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.
