Oven Temp Sensor Ohm Chart
Testing of the sensor has to be performed while the problem is occurring.
Oven temp sensor ohm chart. The most common oven sensor currently used should measure approximately 1080 ohms when at room temperature. The oven does not get to the temperature called for. I removed the temp sensor and tested it. If the problem is present as soon as an oven function is selected and even before heating has begun the sensor itself can be tested to see if it is within specs.
A digital multimeter which measures voltage current and ohms resistance is an excellent instrument for checking thermostats. A bimetallic element made by fusing two different metals together inside responds to a change in temperature by bending as the metals expand at different rates when the element is heated or cooled. When placed in boiling water it rose to 1360 ohms. The oven temperature sensor sends the temperature reading to the control board so the control board knows how hot to heat up the oven.
It s possible that the oven temp sensors malfunctioned. It s only heating the oven to a fraction of the required temperature. You see the oven s temperature gauge as correct but the sensor has other plans. If your range or oven is not heating properly you should check the oven temperature sensor to see if it is good or bad.
Is this a significant difference. When the oven temperature sensor fail. I read here that it should read less than 1100 ohms at room temp that they average 1084 ohms. The resistance of the sensor should read approximately 1080 1090 ohms at room temperature.
The household cooks didn t do anything wrong. If the problem is present as soon as an oven function is selected and even before heating has begun the sensor itself can be tested to see if it is within specs. The sensor may be functioning but it s inaccurate. You need at least two and preferably three resistance measurements at different temperatures to determine if a sensor is good or not.
Ge s wb21x158 bottom one on the picture is approx 16 ohms at room temperature and at 350ºf it is 29 33 ohms. Check the sensor resistance at room temperature only is not sufficient to conclusively prove that the sensor is goo.

If you get a reading that is far off from that you will need to replace the sensor.
Oven temp sensors and other parts help some different sensor ohm readings at room temp.
