We bought this unit when we redid our kitchen in 2002. After a few years, the metal piece inside on the right side seemed to wear away and the oven caught fire. We replaced the unit with an identical unit bought on Amazon (no criticism of them). After about two years, the new unit had the exact same problem: the unit seemed to wear away in the same spot and caught fire. In both cases, there are smoke marks in the same spot, on the inside right near a metal panel.
I am of the opinion that this unit is not safe and seems to have a design or manufacturing defect. Also, the second unit we bought was noisier and seemed to have some sort of mechanical problem, based on the noise it made when in use. If i can find another unit to fit the built in space and trim kit, i will buy that over the Sharp unit. I will also be trying to contact Sharp to see if they have any response to this problem. I will report in if i do hear anything from them.

This is my second Sharp microwave; we bought it to stack over the Jenn-Air Pro Style oven in our kitchen remodel. (I bought the built-in installation kit elsewhere.) Like my previous Sharp, this thing is *powerful*. It cuts the cooking time listed on the instructions for most microwave items by half or close to it. The defrost mode is excellent. Having a carousel makes cooking more even.

All in all, it would be hard to find a better microwave at anywhere near this price point or even significantly above it.

Beautiful microwave oven however the door was dented during shipping. Amazon was superior in the returns department. Will reorder same microwave.

UPDATE: Received a second microwave. It was more damaged than the first one! Plus the door was uneven and when turned on makes a strange sound. I'm returning this one as well. Amazon gets an A+ for their help with returns, the microwave gets an F. I would strongly recommend you stay away from this product.

This microwave oven is an almost exact replacement for my old oven that I purchased seven years ago. The open/close button failed on my old oven and I needed an exact replacement to fit into the exact opening space above my double ovens. This microwave oven is tops! Fast and easy to use. Unfortunately I fixed the open/close button rather easily so now I have two very good microwave ovens.

Beautiful appearance, worked great for a while, then began to vibrate and make loud noises and finally "died" after a year or so of minimal use. Would not recommend if you plan to use it more than a year or so.
