Robert for Model Number ed20pkxsnoo I installed a new defrost timer and put the black wire lead on terminal 2 but the connector fit very loosely on the terminal and it may have shorted out because the timer does not advance and when I force a defrost the timer ticks for 25 minutes but the heater does not come on. I pinched the wire lead with a pliers after removing the timer and reinstalling it again so it is tight on the terminal now but it did not solve the problem. The heater and defrost thermostat both work as it did defrost one time two days after it was installed. I think the poor connection of the black wire lead may have destroyed the timer.
Answer Hello Robert. If the timer is not sending voltage to the heater, you will need to replace the timer 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 Read More...
