3879614018 Genuine PT500 Oven Temperature Sensor for Electrolux Group Ovens, Electrolux Oven Heat Sensor

Genuine Electrolux part 3879614018 is a PT500 temperature sensor for Electrolux group ovens with electronic controls. A PT500 is a platinum resistance sensor whose resistance rises in a steady, known way as it heats, and the control board reads that as oven temperature. Electrolux uses more than one sensor type, so confirm your old sensor is also a PT500 by checking its number before ordering.

Symptoms of a failed oven temperature sensor

The control board relies on the sensor to know when to switch the elements on and off. When a sensor drifts or fails, the oven may overheat and burn food, run cool so cooking takes longer, or refuse to heat at all. Many electronic ovens also show an error code or flash the display when the sensor reads open or short circuit. Sensor leads run through hot areas of the oven, so damaged wiring or a loose connector can cause the same faults as the sensor itself.

Part details

• Genuine Electrolux part 3879614018
• PT500 platinum resistance temperature sensor
• For Electrolux group ovens with electronic controls, model fit not on file
• Check your old sensor is also PT500 before ordering

Testing and fitting the sensor

Turn off the oven at the switchboard. A licensed electrician or qualified technician should handle the wiring. The sensor usually pushes through the back or top of the cavity, held by screws, with its connector behind the panel. Before replacing it, measure the resistance at room temperature and compare it with your service information. Fit the new sensor, reconnect it firmly, then check the oven with an oven thermometer.

Questions about this part

Can I use a PT1000 sensor instead?

No. A PT1000 has double the resistance of a PT500 at the same temperature, so the control would misread the oven heat. Use a sensor that matches your oven's original type and number.
