Symptom / Description

FAULT

Faure FCI / FOP Series / Pyrolyse Confort Oven: Cavity temperature sensor fault F109; electronic board detects open circuit or shorted PT500 / PT1000 temperature sensor.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Faure (Faure FCI / FOP Series / Pyrolyse Confort Oven) models: Open platinum thermal sensor element in oven back wall (nominal ~540 Ω for PT500 or ~1080 Ω for PT1000 at 20°C), broken wiring lead, or pinched heat-resistant cable.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Disconnect oven mains. Access rear panel cavity sensor harness. Measure resistance with multimeter (PT500 reads ~540 Ω at 20°C; PT1000 reads ~1080 Ω at 20°C). Press and hold Départ/Pause and Annulation buttons for 6 seconds until all status indicators flash synchronously and clear fault memory.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Disconnect 230V electrical mains power before removing appliance side or rear panels.
!Ensure tub water or heating chamber has cooled below 30°C before unclipping thermistor probe.
!Use CAT III 600V/1000V insulated test probes when tng at PCB edge connectors.

3. Preliminary Mechanical & Visual Checks

Inspect sensor immersion sleeve for calcification, limescale scale, or thermal paste degradation.
Check wiring harness for pinch points, chafing against chassis metal, and terminal pin oxidation.
Verify probe is firmly seated in its rubber grommet or bracket inside the water/air circuit.

Frequently Asked Questions: Faure F109

FAQ TREE

What does error code F109 mean on a Faure appliance?

Faure error code F109 indicates: Faure FCI / FOP Series / Pyrolyse Confort Oven: Cavity temperature sensor fault F109; electronic board detects open circuit or shorted PT500 / PT1000 temperature sensor..

What is the root cause of Faure error code F109?

The primary root cause for Faure code F109 is: On Faure (Faure FCI / FOP Series / Pyrolyse Confort Oven) models: Open platinum thermal sensor element in oven back wall (nominal ~540 Ω for PT500 or ~1080 Ω for PT1000 at 20°C), broken wiring lead, or pinched heat-resistant cable..

How do I fix or resolve Faure error code F109?

To resolve error code F109: Disconnect oven mains. Access rear panel cavity sensor harness. Measure resistance with multimeter (PT500 reads ~540 Ω at 20°C; PT1000 reads ~1080 Ω at 20°C). Press and hold Départ/Pause and Annulation buttons for 6 seconds until all status indicators flash synchronously and clear fault memory.

Is it safe to clear Faure error code F109 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Faure code F109 persists, the physical component causing On Faure (Faure FCI / FOP Series / Pyrolyse Confort Oven) models: Open platinum thermal sensor element in oven back wall (nominal ~540 Ω for PT500 or ~1080 Ω for PT1000 at 20°C), broken wiring lead, or pinched heat-resistant cable. must be inspected or replaced.

How do I test electrical resistance for Faure code F109 using a multimeter?

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..

What safety protocol must be followed before servicing Faure code F109?

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.
