Customer Questions and Answers for Electronic Clock Control With Overlay (Black) by Whirlpool

Hello Joe. Check and make sure there is no broken or burnt wires on the unit and 240 volts is coming to the unit. Test and see if the clock is sending power to the elements during the bake or broil cycle. If not, you will need to replace the clock assembly WP74009227. 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
