Electrolux Oven Error Code F3

F3 on an Electrolux oven indicates a problem with the oven probe circuit, which includes the RTD temperature sensor, its wiring, the safety thermostat, and the cooling fan. The control board detected a reading outside acceptable parameters, which could mean an open circuit, a short, overheating from heavy use, or a stalled cooling fan. Sub-code F31 points specifically to an open RTD probe or wiring condition.

You should not continue using the oven while F3 is active. The error means the control board cannot reliably read oven temperature, which prevents it from regulating heat accurately or safely. Operating the oven without a functioning temperature sensor could result in overheating or uncontrolled temperature conditions.

Repair costs vary depending on the root cause. An RTD sensor probe is generally an affordable part, with DIY replacement typically costing somewhere in the range of $20 to $60 for the part alone. If a technician is needed for diagnosis and labor, total costs can range from $100 to $250 or more depending on your location and whether additional components such as the cooling fan motor or control board also need attention.

Pressing the CLEAR key is the recommended first step and may resolve the code if it was triggered by temporary overheating, such as after a self-clean cycle. If the fault reappears after clearing, there is likely a hardware issue such as a failed RTD probe, broken wiring, or a stalled cooling fan that needs to be diagnosed and repaired. A recurring F3 will not go away on its own.

To test the RTD probe, disconnect it from the wiring harness and measure its resistance at room temperature using a multimeter. Compare the reading against the probe resistance chart for your specific model. If the resistance does not match the expected value, the probe should be replaced. Also inspect the wiring harness for any visible damage or loose connections before concluding the probe itself is the problem.
