Is there any way to test my old part ?
Answer Hello Albert. Test for power coming into the control board. If so, then you will test for power coming out the board when set to bake and broil. If there is power coming into it, but none going out, you will need to replace the oven control WB27T11313. 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
