Local repair shop told me that the igniters were bad and that I would have to replace them all at cost of almost $300 for parts. Appliance Pro said it was the spark module - at a cost of $38 plus shipping. Video showed an easy replacement. Actual required a bit more searching for the location of the module. Part was located under the cooktop and not in back of the oven. Cooktop removal looked difficult but was not as bad as I thought. Small socket set disassembled the burners. 2 screws to remove panel behind burner switches. 2 more screws to unattach the top panel. Slide forward and lift off top. Spark module was clearly visible and easily replaced. Part was ordered on Saturday, shipped on Monday arrived on Tuesday and installed on Wed. Even with the more disassembly required to find and replace the module, Less than an hour later, stove was fixed and I was out the door with a completed repair and a happy tenant,
