Arthur Martin F110

Arthur Martin error code F110 indicates: Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven: Door lock position mismatch F110; microswitch sensing signals conflict with commanded lock motor position..

The primary root cause for Arthur Martin code F110 is: On Arthur Martin (Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven) models: Bent microswitch operating arm on lock assembly, cracked cam profile, or loose harness wires swapping position 1 and position 2 feedback lines..

To resolve error code F110: Inspect door lock assembly on top frame. Manually actuate lock cam to verify microswitch contacts toggle cleanly between 0 Ω and ∞ Ω. 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 F110 persists, the physical component causing On Arthur Martin (Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven) models: Bent microswitch operating arm on lock assembly, cracked cam profile, or loose harness wires swapping position 1 and position 2 feedback lines. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
