Arthur Martin F105

Arthur Martin error code F105 indicates: Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven: Food meat probe circuit error F105; internal temperature sensing probe jack shorted, open, or reading abnormal resistance..

The primary root cause for Arthur Martin code F105 is: On Arthur Martin (Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven) models: Grease or moisture penetration inside probe cavity jack, damaged silicone cable on meat probe needle, or open PT1000 sensor inside probe tip (~1079 Ω at 20°C)..

To resolve error code F105: Unplug meat probe from cavity socket. Clean socket contacts with isopropyl alcohol. Measure probe resistance across plug pins with multimeter (~1079 Ω at 20°C). 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 F105 persists, the physical component causing On Arthur Martin (Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven) models: Grease or moisture penetration inside probe cavity jack, damaged silicone cable on meat probe needle, or open PT1000 sensor inside probe tip (~1079 Ω at 20°C). 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.
