How To Test Oven Temperature Sensor

Posted on July 6, 2011

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.

4 Thoughts on "How To Test Oven Temperature Sensor"

  1. Bert Posted on August 23, 2016

    Good Afternoon, I have a Frigidaire [Electrolux] Electric Range model FEFL79DBB. I have replaced the oven element but still have a problem obtaining the temperature set on the control panel. I think it may be a problem with the temperature probe. I found that I must have 1080 to 1090 resistance with an Ohm meter
    at room temperature. Is it possible to test resistance without removing the part and accessing thru the
    rear of the stove and opening the connector from the probe. Then test for resistance? Will I get a true reading?
    If I don’t get the proper reading then I would order the part.
    Thanking you in advance for a response.

      Hi Bert,

      The temp sensor could be bad at higher temperatures, but usually if it tests okay at room temp then it is usually good. If the sensor is good, then it is usually a bad control board that is causing the problem.

    My sensor tests at 1103 at room temperature, would that be a good or bad sensor?

      Depending on the temperature of your room that would most likely be good.
