If you are looking for a way to create more counter space in your kitchen, install an under-the-cabinet (or over-the-range) microwave oven. Not only are you freeing up counter space, you are also mounting your microwave at a more accessible height, making it easier to see inside your microwave without having to bend down. An over-the-range microwave is also more aesthetically pleasing, since it has a built-in appearance as opposed to being just another small appliance cluttering up your kitchen. You can install an under-the-cabinet microwave in just a few hours.

  1. 1

    Remove the mounting plate from the rear of the microwave by loosening the holding screws with a Philips screwdriver, turning in a counterclockwise direction. Discard the screws and set the mounting plate aside.

  2. 2

    Use a stud finder to locate the studs on the wall where the microwave will be mounted. Mark the location of the studs (which are usually 16 inches apart) on the wall with a pencil. Measure the width of the space where the microwave will be installed with a measuring tape and mark the centre of the space with a pencil.

  3. 3

    Tape the paper microwave mounting template (which comes with your microwave) to the underside of the cabinet where the top of the microwave will be mounted, lining up the centre line of the template with the pencil mark that indicates the centre of the installation space.

  4. 4

    Hold the mounting plate to the wall, lining up the notch in the centre of the mounting plate to the pencil mark on the wall and the centre line of the paper template above. Choose at least two mounting holes in the mounting plate that line up with the pencil marks that indicate wall studs. Insert lag bolts into the holes and tighten with an adjustable wrench turned in a clockwise direction until tight.

  5. 5

    Insert toggle bolts into the remaining mounting holes on the mounting plate and tighten down with a flathead screwdriver in a clockwise direction.

  6. 6

    Insert a 3/8" drill bit into an electric drill. Drill two holes through the indicated marks on the paper template on the lower side of the upper cabinet. Remove and discard the paper template.

  7. 7

    Use a helper to lift the microwave into place, making sure the slots on the lower rear corner of the microwave fit into the tabs on the lower side of the wall mounting plate. Bring the microwave up into place and have your helper hold it there. Open the upper cabinet doors and run the two mounting bolts through the drilled holes in the bottom of the cabinet and into the threaded fittings on the top of the microwave. Tighten down the bolts with an adjustable wrench turned in a clockwise direction. Plug the power cord into an electrical socket.

Tips and warnings

  • All mounting hardware should come with your microwave. If not, any of the hardware necessary can be purchased at a hardware store or home centre.
