The oven or broiler will not heat up. all the controls light up and work just oven won't heat up. also convection on microwave will not heat up
Answer Hello Debbie. Test at the terminal block for 240 volts. Make sure there is no burnt or damaged wires there as well. If all of that is good, then you need to test and see if your losing power from the relay board of if a thermal cutout is bad 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
