Customer Questions and Answers for Electronic Control Board by Whirlpool

Hello Shawn. You will need to test for power to the control board WP8558455 on the unit. If there is power there and it does not light up, you will need to replace the board on the unit. 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
