How to Install an Over-the-Range Microwave to Maximize Kitchen Space

Your venting options for over-the-range microwaves include a system that directs exhaust outside or one the recirculates air back into the room (which is not recommended for appliances that use natural gas). If you plan to vent the air outside, the installation involves running lengths of ductwork from the microwave's vent outlet through a wall or the roof to a vent cap on the outside of your home. It's best to install the ductwork in the most direct route possible. Carefully plan a path for your ductwork before you begin, then install a vent above the range. Cut through the drywall with a drywall saw to access the vent.

Over-the-range microwaves are typically powered by an outlet located within the cabinet above. Shut off your power and install a new receptacle inside the cabinet. If you're not comfortable doing the electrical work yourself, hire an electrician to complete this task.

Make sure your microwave fan aligns with your exhaust, which can vent through the wall or the roof. On some microwaves, you'll adjust the vent to channel the air in the direction that matches your ductwork. On others, including the one pictured above, you'll position the fan to channel the air through a filter before it recirculates back into the room. 

Many over-the-range microwaves come with a template for mounting. Tape the template to the wall, drill where shown, then remove the template. If there is no template, follow the manufacturer's directions to lay out the mounting holes.

A mounting plate attaches to the wall and bolts through the bottom of the cabinet into the top of the microwave to support the unit. Follow the manufacturer's instructions to attach the mounting plate to the wall. The exact method depends on where the studs fall and on the design of the plate. You need to attach the plate to at least one stud but can typically use toggle bolts elsewhere. 

Hanging a microwave above a range typically requires two people. Make sure the door is latched and have someone help support the weight as you hang the microwave on the mounting plate. Feed the power cord up into the cabinet while you hook the microwave onto the bracket. Adjust it until the top surface sits flush with the cabinet.

Following the manufacturer's directions, bolt the microwave to the cabinet. While your helper holds the microwave in place, screw the mounting bolts down through the cabinet and into the microwave's frame. If necessary, connect the ductwork to the microwave vent outlet. Plug it in and your microwave should be ready to use!
