Over-the-range microwaves are a tried and true kitchen appliance. By combining the cooking capability of a microwave with the ventilation capability of a range hood, an over the range microwave can be both stylish and functional.
Unlike countertop microwaves, over the range microwaves are designed to be installed over a range, stove, or cooktop. Installing an over the range microwave may sound difficult at first, but this is an installation you can do with the help of a friend or household member. In this post, we’re covering how to install an over the range microwave and answering some common questions we receive at The Range Hood Store about over the range microwaves.
What is an Over the Range Microwave?
An over the range microwave is specifically designed to be mounted next to cabinets and above a cooking range, cooktop, or stove. This positioning allows it to serve as a convenient cooking appliance and a ventilation system for your kitchen.
By incorporating a built-in ventilation system with a fan and filters into its base, over the range microwaves help to remove smoke, steam, and odors that arise from cooking on the cooking surface below.
Most over the range microwaves have all the features and settings found in traditional countertop microwaves, and some models incorporate additional features like convection cooking or sensor cooking, depending on the model.
What Size Over the Range Microwave Do You Need?
To determine what size over the range microwave you need you should collect accurate measurements of the cutout above the cooking surface. Measure the width, depth, and height of the space that is available. There may also be ventilation requirements specified by the manufacturer of your cooking surface that should be accounted for. Also, take into consideration your personal style to ensure the microwave you choose will fit seamlessly into the heart of your home.
Width: Most over the range microwaves are 30 inches wide, which is also the most common width of freestanding ranges. To ensure that 30 inches is the right width, measure the width of space above your cooking surface. There are also compact over the range microwaves better suited for smaller spaces which are usually 24 inches wide.
Height: Over the range microwaves have a standardized height of 17 inches. Measure the height from the bottom of the upper cabinets to the cooking surface of your range. There are also specialized models called low-profile over the range microwaves which can fit in spaces as low as 10 inches.
Depth: Over the range microwaves have different depths, usually ranging between 15 and 18 inches. Measure the depth from the wall to the front of your range to determine the maximum depth of the microwave that will fit comfortably in the space.
Over the range microwaves should be installed around 30 inches above the top of the cooking surface and far enough away from any perpendicular walls so that the door can fully open.
Taking accurate measurements of the available space and considering any ventilation requirements will help you determine what size over the range microwave you need.

Stud finder
-
Level
-
Screwdriver
-
Pencil
-
Mounting template (usually included with microwave)
-
Mounting Hardware (included with microwave)
-
Any other tools/materials that are specified in the model’s manual
Safety Precautions
Safety first! Ensure you:
-
Turn off power to the area.
-
Wear safety glasses and gloves.
-
Have a helper for heavy lifting.
Preparation Steps
-
Familiarize yourself with the microwave’s installation manual.
-
Check for venting requirements, and determine if your microwave vents externally or recirculates air.
-
Remove any items from the stovetop and surrounding area.
-
Save yourself any headaches and test the microwave before installation.
Removing the Old Microwave
-
Ensure the power is off to avoid electrical hazards.
-
Unplug and disconnect any venting and electrical connections.
-
Remove the mounting hardware by unscrewing the microwave from the cabinet above, and supporting it to prevent dropping.
-
Remove the microwave from the mounting plate. Usually, this involves tilting the top of the microwave towards you at an angle and lifting the back of the microwave up and off of the mount.
-
Remove the mounting plate. If you’re installing the same brand as your previous microwave, there’s a chance your new microwave will use the same bracket. Be sure to check the included hardware, as this will save you a few steps.
Now you are ready to install the new microwave!
Installing the Mounting Plate
-
Use a stud finder to locate studs for secure mounting.
-
Tape the mounting template on the wall, ensuring it’s level and matches the corresponding holes on your template to the stud(s).
If you do not have a template, you can request a new template from the manufacturer or contact us for further assistance.
-
Mark the mounting spots with your pencil, ensuring at least one is on a wall stud. Then using an appropriate-sized drill bit, drill the pilot holes for the bolts and/or wall anchors.
-
Remove the template, you do not want to leave the template as this can become a hazard.
-
Attach the mounting plate by securing it to the wall with bolts and/or wall anchors ensuring it’s firmly in place. Do not over-tighten.
Drilling the Top Mount/Mounting Bracket Holes
Follow similar steps as the mounting plate to prep where you will attach your microwave to the cabinetry.
-
Position and tape the top mount template to the bottom of the cabinetry
-
Mark The Holes.
-
Remove the template.
-
Drill the top mount pilot holes into the cabinetry.
-
If the bottom of the cabinets is recessed, be sure to use appropriate-sized blocks of wood to provide a flush mounting surface for the top of the microwave.
Prepping the Microwave
-
Adjust the microwave’s venting configuration if necessary. Your instruction manual should have detailed instructions for each setting and how to set it up. If you are using a recirculating configuration you should also ensure your filters are installed at this point.
-
Attach the mounting bracket per your manufacturer’s instructions.
Mounting the Microwave
-
With your helper, tilt the front/top of the microwave forward slightly, and lift the microwave to the wall mounting bracket.
-
Line up the hook or mounting slots and rest the rear of the microwave on the wall mounting bracket.
-
Thread the power cable through the previously drilled hole and take up any excess slack.
-
Insert the top mounting bolts through the holes previously drilled and screw each bolt by hand. Ensure the power cable isn’t caught.
-
Using a screwdriver or electric drill, tighten down the mounting bolts until snug. Do not over-tighten.
Venting
-
If venting externally, align and connect the ducting to the transition/damper outlet.
-
Secure with a clamp or heat-resistant duct tape.
Power and Test
-
Plug in the microwave.
-
Turn on the microwave to test functionality. Test with food or a beverage to avoid any damage to the unit.

Q: Can Over the Range Microwaves be Vented Outside?
A: One of the most common questions we receive in regard to over the range microwaves is about how they are ventilated. Similar to range hoods, over the range microwaves can be vented outside through the use of ducting or can be operated in a recirculating mode.
It's important to note that some microwaves may offer both venting outside and recirculating options, while others may be limited to only one of these modes. Determining what type of venting option you need before purchasing an over the range microwave is crucial.
Q: How long does it take to install an over-the-range microwave?
A: The installation process typically takes 1-2 hours, depending on your experience and preparation.
Q: Can I install the microwave myself, or do I need a professional?
A: While a professional can ensure a perfect installation, a DIY enthusiast can handle the task with proper tools and instructions.
Q: What if my kitchen doesn’t have proper venting for the microwave?
A: Many over-the-range microwaves offer recirculating vent options that don’t require external venting.
Q: What is a Microvisor?
A: A Microvisor is a product designed to address the issue of fumes escaping while cooking on the front burners of a range or cooktop when using an over the range microwave as an exhaust system. When a Microvisor is installed, it captures and redirects up to 90% of the total cooking byproducts to the over the range microwave’s exhaust. Additionally, the Microvisor provides a heat shield to protect the over the range microwave from the heat generated during cooking.
In conclusion, over the range microwaves offer a versatile and efficient solution for your kitchen needs. Not only do they provide the convenience of a microwave, but they also serve as a range hood to keep your kitchen well-ventilated. When choosing an over the range microwave, it's important to consider the size that fits your space and meets your style preferences.
