I purchased 4 new Maytag applainces through Whirlpool, because of a kitchen remodel, on May 12, 2009. They were installed the second week in June. The vented microwave, installed above the stove, did not heat up to cook. The repairman states that the circuit board needs to be replaced, and will take 10 days -2 wks to arrive. In addition, the plate on the microwave, states that it was manufactured in 2006. My intent was to purchase a new product; not one that is already 3 yrs old. Please explain why I was sent a 3 yr old product; I expect to have it replaced by a new model. Susan Diemer
