GE Er01

GE error code ER01 indicates: GE Profile / Cafe / Monogram True Convection & Advantium Oven: Cavity temperature sensor open circuit Er01; electronic controller reads infinite resistance from the PT500 / PT1000 oven probe..

The primary root cause for GE code ER01 is: On GE ovens utilizing Cafe / Monogram True European Convection with Direct Air, Advantium speedcook technology, and digital oven controller: Broken platinum resistor probe inside cavity, heat-damaged silicone wiring behind rear insulation, or loose PCB terminal..

To resolve error code ER01: Isolate power at breaker. Disconnect sensor plug at rear. Measure probe resistance (~538 Ω for PT500 or ~1078 Ω for PT1000 at 20°C). Replace if infinite. Press Cancel/Off key, turn off branch circuit breaker for 60 seconds, restore power and set the electronic clock time.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if GE code ER01 persists, the physical component causing On GE ovens utilizing Cafe / Monogram True European Convection with Direct Air, Advantium speedcook technology, and digital oven controller: Broken platinum resistor probe inside cavity, heat-damaged silicone wiring behind rear insulation, or loose PCB terminal. 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.
