oven will only heat to 225. This problem started soon after purchase. It used to be intermittent. By rapidly pushing the preheat button several time it would go to the selected temp. Now it go’s to 225 no matter what you select. Is a complete control head required or can I change a part in the head. This problem occurs on pre-heat and ordinary bake.
I would say the temp sensor is bad, part # AP2970860
