Electrolux Range Error Code Convection Roast + Clean (LEDs 3,5)

This LED combination indicates that the electronic control board has detected a shorted temperature probe circuit in the oven. The oven temperature probe is responsible for measuring the internal oven temperature and reporting it back to the control board. When the probe circuit resistance falls outside the expected 1050 to 1100 ohm range, the board flags this fault to prevent unsafe or inaccurate oven operation.

It is not recommended to continue using the oven while this fault is active. A shorted temperature probe means the control board cannot accurately monitor oven temperature, which could result in the oven overheating or failing to regulate heat properly. The range's surface burners may still function, but the oven should remain out of service until the fault is diagnosed and repaired.

Repair costs vary depending on which component is faulty. Replacing the oven temperature probe is typically the less expensive fix, with parts generally ranging from $20 to $60 and professional labor adding $75 to $150 depending on your area. If the electronic control board requires replacement, parts alone can range from $150 to $350 or more, with total professional repair costs potentially reaching $250 to $500. Diagnosing the probe first with a multimeter can help avoid purchasing an unnecessary control board.

A knowledgeable DIYer can diagnose this fault by testing the oven temperature probe resistance with a multimeter. Disconnect the probe and measure resistance at its terminals; a reading between 1050 and 1100 ohms means the probe is good and the control board likely needs replacement. If the reading is significantly below 1050 ohms or near zero, the probe or its wiring harness needs to be replaced. Both the probe and the control board are serviceable components, though board replacement requires careful handling of wiring connectors.

Resetting the range by cutting power at the breaker or unplugging it may temporarily clear the fault display, but the error will return as soon as the control board re-evaluates the probe circuit and detects the short again. A reset does not address the underlying hardware problem. Permanent resolution requires testing the probe resistance and replacing the faulty component, either the probe or the control board.
