For Whirlpool Dryer Cycling Thermostat (Part Number: AP3131939)

My dryer heat does not warm up enough on the high setting, the medium setting seems to work just fine, but takes longer to dry a load. There is no blockage and I was looking for a thermistor part but do not see one on the parts list your site has. Should we try to replace the thermostat? What other issues would cause the high setting only to no longer work?

Therese for Model Number LER8620PWO

ANSWER Hello Therese. You will need to check the temperature coming out of the dryer when on high heat. It should read around 160° on the high end, and 110° on the low end. If it is cycling before the 155-160° mark, you may have a bad cycling thermostat. You can test this with a multi-meter with temperature TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
