GE AL01

GE error code AL01 indicates: GE Profile / Cafe TwinChill French Door & Side-by-Side Refrigerator: Critical freezer high temperature alarm AL01; freezer compartment temperature has risen above safe threshold of -9°C..

The primary root cause for GE code AL01 is: On GE refrigeration units featuring dual-evaporator TwinChill refrigeration system, multi-flow air tower, and electronic sealed system inverter compressor: Prolonged domestic power outage, freezer door left open, heavy loading of unfrozen food, or refrigerant leak..

To resolve error code AL01: Mute acoustic alarm with Alarm Reset button. Activate Super Freeze mode for 12 hours. Verify compressor runs and evaporator chills down to -18°C. Reset: Press and hold Door Alarm and Express Chill/Quick Ice buttons simultaneously for 5 seconds until control board beeps twice.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if GE code AL01 persists, the physical component causing On GE refrigeration units featuring dual-evaporator TwinChill refrigeration system, multi-flow air tower, and electronic sealed system inverter compressor: Prolonged domestic power outage, freezer door left open, heavy loading of unfrozen food, or refrigerant leak. 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.
