Scholtès Refrigerator / Freezer LC

Scholtès error code LC indicates: Scholtès Pure Cold Built-in Total NoFrost Refrigerator: Diagnostic code LC indicates low temperature condition in fresh food compartment; fresh vegetables freezing on bottom crisper shelves..

The primary root cause for Scholtès code LC is: On Scholtès refrigerators (Scholtès Haute Horlogerie Culinaire sensors and micro-electronic platform architecture): Motorized air damper baffle stuck wide open, drifting RC thermistor (falsely reading high Ω), or shorted damper triac on PCB..

To resolve error code LC: Disconnect power. Remove air duct cover and inspect damper baffle. Measure stepper motor coils (200–400 Ω). Measure fresh food NTC resistance (7.9 kΩ at 0°C). Replace stuck damper. Press and hold Alarm Reset pad for 5 seconds, verify compartment display stops blinking, and allow 12h for complete stabilization.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Scholtès code LC persists, the physical component causing On Scholtès refrigerators (Scholtès Haute Horlogerie Culinaire sensors and micro-electronic platform architecture): Motorized air damper baffle stuck wide open, drifting RC thermistor (falsely reading high Ω), or shorted damper triac on PCB. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
