How To Test Oven Temperature Sensor
Testing the temperature sensor probe on your oven is easy. With the sensor at room temperature, measure the resistance between the two prongs at the end of the sensor connector. The resistance of the sensor should read approximately 1080 – 1090 ohms at room temperature. If you get a reading that is far off from that, you will need to replace the sensor. The oven temperature sensor sends the temperature reading to the control board so the control board knows how hot to heat up the oven. This test works for most common temperature sensors.
See the chart below for more temperature and resistance values.
If you find that you have a bad oven temperature sensor, you can search with the model number from your range/oven at the top of this page to find the correct oven temperature sensor for your model. Click here for common locations to find your model number tag.
