Customer Questions and Answers for Dryer Thermal Cut-Off Kit by Whirlpool

Hello Rick. You will need to test the breaker, terminal block, and main board for power. If all that is good, and the unit wont start, then test the thermal fuse WP3392519, a broken belt, or bad door switch. 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
