The HMV3053U was a 300 Series over-the-range microwave, 1.6 cubic feet at 1,550 watts in stainless. Over-the-range microwaves of this generation are usually a decade old by now, and the part that has almost certainly been neglected the whole time is the ventilation damper inside the unit – a flap that opens when the blower runs and closes when it stops. A damper sticking open lets cold outside air back down into the kitchen, which owners blame on draughty windows.
