Customer Questions and Answers for Dryer Door Latch Mechanism by Bosch

Hello Cynthia, You will want to check your door switch 00189410 to make sure that when the door is closed that you have continuity. If not then the door switch is bad and needs to be replaced. If the door switch checks good then you will want to make sure that you check the thermal fuses to ensure that they are good. A bad thermal fuse can cause dryer not to run. No continuity on the thermal fuse means that the fuse 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
