Sauter AL01

Sauter error code AL01 indicates: High temperature alarm in freezer compartment..

The primary root cause for Sauter code AL01 is: The temperature inside the freezer is too high. This could be due to the door being left open, a recent large addition of unfrozen food, or a fault in the cooling system..

To resolve error code AL01: Ensure the door is closed properly. Wait 24 hours to see if the temperature stabilizes. If the alarm persists, check for excessive frost buildup and inspect door seals. May require professional service.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Sauter code AL01 persists, the physical component causing The temperature inside the freezer is too high. This could be due to the door being left open, a recent large addition of unfrozen food, or a fault in the cooling system. 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.
