Appliance Repair Questions? Ask a Technician for Answers ASAP
If the oven is having this much trouble the tech should suspect a bad bake burner causing the problem, this is part number WB16T10002, this is because the burner ladder holes were either deformed in manufacture or starting to corrode, this would be the way to go if after 2 igintors and several other parts that had nothing to do with this problem.
