The heating rod does not get hot in the defrost state. What could be wrong? The defront timer, thermostat or the rod itself? Thanks! Jerome

Jerome for Model Number bb20vse

ANSWER Hello Jerome. You will need to test the thermostat 10442409 and the heater 10991109. They should read closed for continuity when cold. If they test good, you will need to replace the timer R0131577. 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
