We purchased this refurbished microwave to replace an older model of the same size and wattage. The microwave worked fine for the first few weeks but began to randomly not power up when we pressed start. The cook timer would continue to count down but the microwave would not come on. We finally figured out that the microwave would start every time, if you press down on the top of the door after you press start. We think it is a design flaw in the door. The other negative is that the microwave is not nearly as powerful as the previous microwave we had with the same wattage. We have to add at least 30 seconds to any cooking directions to get them to be hot enough. Otherwise, the stainless steel is very stylish and the inside is extremely easy to clean.
