Always disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Faure error code A1 indicates: High temperature alarm in freezer..
The primary root cause for Faure code A1 is: The freezer temperature has risen to an unsafe level. This could be due to the door being left open, a power outage, or a fault in the cooling system..
To resolve error code A1: Ensure the door is closed properly. If the alarm persists after several hours, check for frost buildup, and verify the condenser fan and compressor are running.
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Faure code A1 persists, the physical component causing The freezer temperature has risen to an unsafe level. This could be due to the door being left open, a power outage, 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.
