How do you check if the thermal fuse is bad?

Answer Hello Mike. Test for continuity. The thermal fuse 675813 should read closed. 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

Answer Hello Steve,
It may be showing the lock out due to another issue. This unit if you have multiple keys stuck on on the touch pad then the unit will cause the lock light to flash. Try to disconnect the ribbon harness between touch pad and control board. Make sure the contacts are clean and reinsert. If the light still will not goe off then you would need to replace the membrane switch.
