1. Pre-Intervention Electrical Safety Protocols

!High-Voltage Safety Protocol: Disconnect 230V power before unplugging edge connectors or removing PCB.
!High Voltage DC Warning: Wait at least 5 minutes for SMPS and inverter filter capacitors (up to 380V DC) to discharge safely.
!Electrostatic Discharge (ESD): Ground yourself to the metal chassis or wear an antistatic wrist strap before touching circuit tracks.

3. Preliminary Mechanical & Visual Checks

Inspect PCB tracks with a magnifying glass for blown triacs, darkened copper tracks, or cold solder joints on power relays.
Check electrolytic capacitors for bulging tops or leaked electrolyte residue around pins.
Verify edge connector locking clips are intact and pins are free of vibration fretting corrosion.

Frequently Asked Questions: Arthur Martin F104

FAQ TREE

What does error code F104 mean on a Arthur Martin appliance?

Arthur Martin error code F104 indicates: Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven: Electronic control board over-temperature F104; thermal sensor on main PCB measures excessive temperature (> 85°C)..

What is the root cause of Arthur Martin error code F104?

The primary root cause for Arthur Martin code F104 is: On Arthur Martin (Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven) models: Cooling fan failure during extended high-temperature bake or pyrolytic cycle, blocked top ventilation slits in cabinet, or deteriorated cavity insulation..

How do I fix or resolve Arthur Martin error code F104?

To resolve error code F104: Check kitchen installation clearances (minimum 50mm rear air gap). Ensure cabinet vents are clear of obstructions. Verify cooling blower operation. Hold Départ/Pause and Option buttons firmly for 5 seconds until the red indicator extinguishes and service memory resets.

Is it safe to clear Arthur Martin error code F104 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Arthur Martin code F104 persists, the physical component causing On Arthur Martin (Arthur Martin AOB Series / Pyrolyse Chaleur Tournante Oven) models: Cooling fan failure during extended high-temperature bake or pyrolytic cycle, blocked top ventilation slits in cabinet, or deteriorated cavity insulation. must be inspected or replaced.

How do I test electrical resistance for Arthur Martin code F104 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test PCB Power Supply Rails & DC Bus Filter Capacitors across Across SMPS output electrolytic capacitors on low-voltage side (test bench verification). Expected nominal reading is Low-voltage rails: +5.0V DC (Logic), +12.0V DC (Relays), +3.3V DC (MCU). Relay coils: 200Ω–450Ω.. Tolerance: DC rail ripple must remain <50mV. Direct continuity (0Ω) across DC bus rails indicates dead short..
