Answer Hello Jac5839. You need to check and see if the neutral is dropping going to the fan motor and if so, you will need to trace and see where you are loosing the neutral at. 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
I have replaced this fan motor assembly but it will not come on, also replaced electronic control board, inverter box and control panel and still does not come on. what else could control this fan motor? Thanks, KJL

Answer KJL, You'll need to check for the DCvoltage at the fan motor, from the control board. The important wires to check are : White wire across to the Red wire, should have a constant 12 VDC. The White wire across to the Yellow wire, should have anywhere from 5 to 17 VDC, for the variable speed control. And the Blue wire is the "feed back" to the Main control board. You may also want to do the same checks at the main control board on the P7 connector. Sounds like you may have a loose or broken wire ? Thanks and Good Luck
