How do I know if my oven temperature sensor is bad?

Common symptoms include inaccurate temperature readings, the oven not heating properly (too hot or not hot enough), long preheat times, or error codes on the display. A multimeter can be used to test the sensor's resistance for a definitive diagnosis, comparing it to the manufacturer's specifications.

Can I replace the oven temperature sensor myself?

Yes, replacing an oven temperature sensor is generally considered a moderate DIY repair. It typically involves disconnecting power, accessing the sensor, unmounting it, disconnecting the wiring, and installing the new part. Always ensure power is disconnected before starting any repair.

What causes an oven temperature sensor to fail?

Over time, constant exposure to high heat can degrade the sensor's internal components, leading to inaccurate readings or complete failure. Physical damage, such as impact or corrosion, can also cause a sensor to malfunction, preventing it from sending correct data to the control board.
