Favorit ER07

Favorit error code ER07 indicates: Favorit SwissBake / CombiSteam Built-in Pyrolytic Convection Oven: Diagnostic fault code ER07 registered by the microcomputer controller. Built-in oven circular fan forced-convection heating element open circuit (2400W, nominal 22-25 Ω) (code ER07).

The primary root cause for Favorit code ER07 is: On Favorit SwissLine and European precision appliances built for high durability engineered with PT1000 platinum RTD probe (1080 Ω at 20°C), 2400W convection circular element (22-25 Ω), radial exhaust cooling turbine (160-220 Ω), and motorized door interlock latch: nickel-chromium alloy coil burned open under thermal load, dry fatigue fracture, or burned terminal spade. Metrological tolerance verification: circular element resistance 22 Ω to 25 Ω at 20°C (2400W); insulation resistance to earth sheath >50 MΩ at 500V DC..

To resolve error code ER07: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: remove rear baffle plate inside cavity, disconnect power spades and measure resistance with digital ohmmeter. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Turn temperature knob to Off. Press and hold Clock and Stop buttons for 5 seconds until confirmation tone sounds, wiping error state from EEPROM.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code ER07 persists, the physical component causing On Favorit SwissLine and European precision appliances built for high durability engineered with PT1000 platinum RTD probe (1080 Ω at 20°C), 2400W convection circular element (22-25 Ω), radial exhaust cooling turbine (160-220 Ω), and motorized door interlock latch: nickel-chromium alloy coil burned open under thermal load, dry fatigue fracture, or burned terminal spade. Metrological tolerance verification: circular element resistance 22 Ω to 25 Ω at 20°C (2400W); insulation resistance to earth sheath >50 MΩ at 500V DC. 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.
