Bompani F20

Bompani error code F20 indicates: Bompani Serie Divina / Linea Built-in Multifunction Pyrolytic & Convection Oven: Operational diagnostic fault code F20 signaled by internal electronics. High-temperature safety limit thermostat tripped open circuit (manual reset bimetal 350°C).

The primary root cause for Bompani code F20 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: Cavity cooling blower failure caused heat build-up on upper roof, or cavity thermostat failed to cycle Multimeter diagnostic parameter: safety thermostat continuity <0.1 Ω when reset; open circuit (>10 MΩ) indicates tripped or damaged bimetal..

To resolve error code F20: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: locate safety thermostat on oven top casing, press red manual reset button, and test contact continuity (<0.1 Ω). 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 F20 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: Cavity cooling blower failure caused heat build-up on upper roof, or cavity thermostat failed to cycle Multimeter diagnostic parameter: safety thermostat continuity <0.1 Ω when reset; open circuit (>10 MΩ) indicates tripped or damaged bimetal. 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.
