I have a frigidaire gas oven will not heat up. Remains in preheat mode.
Answer Hello Bob. Check and see if the igniter is glowing. If not, and there is power to it, you will need to order and replace the igniter 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
