How can I know if the motor fan works or not?
Answer Hello Jesus. You can test for 120 volts to the fan motor. If there is power there, and it does not work, replace the fan motor. 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
