ANSWER Hello Z. You will need to test the defrost heater 5303918247 and the defrost thermostat 5303918202. They should read closed for continuity when cold. If they are good, you will need to replace the timer 240545401. You can test this with a multi-meter TJMA-DM1. 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
