Sauter F03

Sauter error code F03 indicates: Sauter Saveurs / Confort / Amphora / SFP Pyrolytic Oven: Tangential cooling fan speed error F03; fan operates at insufficient RPM or tachometer signal is missing..

The primary root cause for Sauter code F03 is: On Sauter ovens featuring Saveurs gentle convection airflow, Conseil Température cooking guide, and Amphora enamel heat reflection: Degraded blower motor run winding, dusty fan bearings, or failed Hall sensor IC..

To resolve error code F03: Clean fan roller of lint and dust. Measure motor coil resistance (~240–320 Ω). Verify tachometer signal line voltage (pulses 0–5V DC). Turn selector to Off, drop power at the branch breaker for 60 seconds, restore supply and touch the clock icon to recalibrate.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Sauter code F03 persists, the physical component causing On Sauter ovens featuring Saveurs gentle convection airflow, Conseil Température cooking guide, and Amphora enamel heat reflection: Degraded blower motor run winding, dusty fan bearings, or failed Hall sensor IC. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
