What is the ohm resistance to p/n ap4009926?
Answer Hello Gene. The manufacture recommends to check for resistance across the heater. If there is resistance the heater is good. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
