Arthur Martin E05

Arthur Martin error code E05 indicates: Arthur Martin ARA / ARB Series / Silentic Froid Refrigerator: Door open sensor switch fault E05; interior LED lighting or open door chime stays on continuously..

The primary root cause for Arthur Martin code E05 is: On Arthur Martin (Arthur Martin ARA / ARB Series / Silentic Froid Refrigerator) models: Stuck magnetic reed switch inside control frame, dislodged door magnet on inner door profile, or worn push-button microswitch..

To resolve error code E05: Test door switch continuity with door closed (< 1 Ω). Test reed switch by passing a handheld neodymium magnet over the sensor location. Hold Départ/Pause and Option buttons firmly for 5 seconds until the red indicator extinguishes and service memory resets.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Arthur Martin code E05 persists, the physical component causing On Arthur Martin (Arthur Martin ARA / ARB Series / Silentic Froid Refrigerator) models: Stuck magnetic reed switch inside control frame, dislodged door magnet on inner door profile, or worn push-button microswitch. 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.
