Most microwaves can be used with a generic wall mount if they conform to the recommended weight and size dimensions. Some microwave manufacturers, such as GE and Whirlpool, make mounting kits that fit specific models.
Generic microwave wall mounts may be as simple as two brackets, while others may include a shelf. Since a microwave is a relatively heavy appliance, any mounting bracket should be secured to the wall studs with wood screws. To find a mounting kit, check the manufacturer's website for a coordinating accessory, or measure the microwave unit to find a suitable generic alternative.
Before installing a wall bracket, select a location near an electrical outlet. Find and mark the location of the studs. Position the bracket on the wall, make sure it is level, and mark the holes. Pre-drill the holes, and then secure the bracket
Standard microwaves can be mounted on a wall if they are not directly above a stove. If installing over a stove, select an over-the-range microwave unit that has a filter and vent for circulating the air from the stove. Over-the-range models come with a mounting kit so that the unit can be secured to the wall and the cabinet above it. Microwave options include horizontal exhaust, vertical vent and non-vented, which recirculates the air.
