Electrolux Range Error Code Convection Bake + Clean (LEDs 2,5)

The Convection Bake + Clean LED combination (LEDs 2 and 5) on an Electrolux range signals that the electronic control board has detected an open circuit in the oven temperature probe circuit. The oven temperature probe, also called an RTD (resistance temperature detector), is a sensor inserted into the oven cavity that continuously reports oven temperature to the control board by varying its electrical resistance. Under normal operating conditions at room temperature, this probe should measure between 1050 and 1100 ohms. An open circuit means the control board is receiving no usable signal from the probe, which prevents it from regulating oven temperature safely during bake or self-clean cycles.

The most common cause of this fault is a failure within the probe itself, where the sensing element or its internal wiring has broken, creating an open in the circuit. However, the wiring harness connecting the probe to the control board is also a frequent culprit. Connectors can corrode, pins can back out of their housings, and wires can chafe or burn through, particularly near the oven cavity where heat exposure is significant. A broken connection anywhere along that circuit path will produce the same open-circuit fault code.

Diagnosis begins with measuring the probe resistance directly at the probe connector using a multimeter. A reading within the 1050 to 1100 ohm range confirms the probe is functional, which then points responsibility toward the wiring harness or the electronic control board itself. If the probe reads significantly higher, lower, or shows an open (OL) reading, the probe requires replacement. If the probe tests good and the wiring shows continuity throughout, the electronic control board is the likely failed component and should be replaced.
