I have a Kitchenaid microwave/oven combo that the membrain switch went out in. The part has been on back order for 6 months now. The appliance was produced in August of 1999 so this tells me that the kitchenaid brand has a life span of 10 years. Before this incident, I purchase a Kitchenaid refrigerator and stove top based on the reputation of being top of the line. Never again will I purchase this brand. Brands like Frigidaire costs a fraction of the price and last twice as long. I have contacted Kitchenaid but received the same message over and over again. read full review »
