Rosieres Er02

Rosieres error code ER02 indicates: Rosières Sublime / Origine / Paul Bocuse Pyrolytic Oven: Cavity temperature sensor short circuit Er02; measured resistance across probe terminals drops below 100 Ω threshold..

The primary root cause for Rosieres code ER02 is: On Rosières ovens powered by French culinary precision thermal regulation, Paul Bocuse pyrolytic cavity, and GIAS Cuore microcomputer controller: Pinching of probe lead wires by rear metal backplate screws, crushed fiberglass sleeving, or internal short in sensing bulb..

To resolve error code ER02: Inspect wiring harness from probe to PCB for pinched insulation. Verify probe resistance disconnected from PCB (nominal ~538 Ω / ~1078 Ω at 20°C). Return oven selectors to 0, switch off the kitchen circuit breaker for 60 seconds, re-engage and reset the rotary clock timer.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code ER02 persists, the physical component causing On Rosières ovens powered by French culinary precision thermal regulation, Paul Bocuse pyrolytic cavity, and GIAS Cuore microcomputer controller: Pinching of probe lead wires by rear metal backplate screws, crushed fiberglass sleeving, or internal short in sensing bulb. 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.
