What is the resistance reading of thermistor control #ap3866842?
Mine is reading 48k. All my other switches test OK
Answer Hello Mark. The control thermistor on your dryer should have a room temperature resistance reading of approximately 50K ohms. If not then the thermistor is faulty and would need to be replaced.
My dryer no longer heats up. I have done some research, and some diagnosis based on the code E5B. My voltage at the block is 240, my voltage at the heating element is the same. I tested the Thermistor next, which reads approx. 15K Ohms at room temperature, indicating that it would need replacement. Logic tells me that if the heating element has 240 volts, that it should heat, unless it's bad. I would think that if the thermistor were bad, there would be no voltage at the element. Is this not correct? I am trying to determine whether I need the thermistor, or the element.
Answer Hello Steve. That is correct. If there is 240 volts there, it should heat. Also, test the element for continuity. It should read closed. If open, it is bad. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
