Customer Questions and Answers for Timer by Whirlpool

Hello Sherri. You will need to test the lid switch 12001187 and make sure it is reading closed for continuity with the lid closed. If not, it will cause the problems you are having. You can test this with a multi-meter 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
