A:AnswerOurs did the same thing. We opted to replace the microwave, as repairing the magnetron wouldn't have been worth the cost. We got a great deal on a replacement at Best Buy. Ours was less than 7 years old.
A:AnswerMeasure the width to make sure that it fits between your cabinets and you should be fine. I’ve replaced two ge microwaves in the last month (mine and my parents) with this one and they were the same. Used the old hanger too. You will more than likely have to drill holes in the upper cabinet because the bolt holes were not in the same spot on the new one.
A:AnswerTrick question! An over the range microwave doesn’t go into a “housing”. It has lights and filters on the bottom that should not be blocked. Hey “Bill” did you really go online and post this question and expect that someone was going to research it for you? You’re evidently not going to get expert help from BB either.
