Bompani F03

Bompani error code F03 indicates: Bompani Serie Divina / Linea Built-in Multifunction Pyrolytic & Convection Oven: Operational diagnostic fault code F03 signaled by internal electronics. Cavity over-temperature condition (>320°C in baking or >520°C during pyrolytic clean).

The primary root cause for Bompani code F03 is: On Bompani kitchen suites engineered with PT1000 cavity RTD sensor (1080 Ω at 20°C), bi-directional tangential cooling fan, motorized pyrolytic door lock, and 2300W convection circular element: Heating element control relay welded shut on power PCB, triac shorted, or thermal runaway Multimeter diagnostic parameter: de-energized relay contacts must read open circuit (>10 MΩ); closed contacts with coil unpowered indicate failure..

To resolve error code F03: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: test continuity across relay output contacts with power removed to verify whether contacts are welded shut. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Turn oven selector knob to OFF position. Press and hold Temp and Timer buttons simultaneously for 5 seconds until 'rSt' flashes, then press Start to confirm memory wipe.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bompani code F03 persists, the physical component causing On Bompani kitchen suites engineered with PT1000 cavity RTD sensor (1080 Ω at 20°C), bi-directional tangential cooling fan, motorized pyrolytic door lock, and 2300W convection circular element: Heating element control relay welded shut on power PCB, triac shorted, or thermal runaway Multimeter diagnostic parameter: de-energized relay contacts must read open circuit (>10 MΩ); closed contacts with coil unpowered indicate failure. 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.
