When I turn on my convenction oven the fan in the back does not run. How do test to see if it is the fan or the circuit board?
Answer Hello Heather. You will access the wires for the fan motor, and test when the unit is on for power. If it is there, replace the fan motor 74004947 in the unit. Be careful as there is live power when testing this. 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
