We pulled oven from the wall looking for a switch to reset, according to what we had seen on utube, we could not find anything that looked similar, figuring we had nothing to loose we looked on top of the oven and found exactly what they showed on utube. We tested the part with ohm meter for continuity and it was not working. Not knowing if this was our only problem or not we ordered part based on part # on the part. It came in 2 days! We put it in and yes it worked. Figured we saved at least 200.00 plus.
