How do you test to see if the temperature switch needs replacing?
Jofsmyrna for Model Number Whirlpool dryer LEQ9858LWO
Answer Hello jofsmyrna. On the low setting, should read 10 ohms max and on high setting should read 10K min. 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
How easy or difficult is it to replace this part?
Mike for Model Number 8528330
Answer Hello Mike. The temperature switch 8528330 is not hard to replace. You will disconnect the power and pull off the switch knob. Then remove the two screws in the back corners of the control panel and access the switch by pulling the control forward and flipping it backwards and access the switch. Unplug the wires and release the locking tab and twist the old switch to remove it. Install the new switch in reverse order.
