How To Replace Over The Range Microwave With Vent
Upgrading your kitchen’s ventilation system can make a big difference in air quality and cooking performance.
While over-the-range microwaves offer the convenience of two-in-one cooking and venting, replacing yours with a dedicated range hood can provide more powerful and efficient air clearance.
In this guide, we’ll walk you through the process of removing an over-the-range microwave and installing a new range hood in its place, as well as discuss key considerations to help you find the right fit for your kitchen.
Removing the Over-the-Range Microwave: Step By Step
Before you can install a new range hood, you’ll need to carefully remove your existing over-the-range microwave. This process typically requires two people to ensure the microwave is safely handled and doesn’t get damaged.
1. Clearing The Upper Cabinet
The first step is to clear out any items that may be stored in the upper cabinet above the microwave. This cabinet is where the microwave’s power cord is plugged in and, if the microwave is vented, where the ductwork connects.
Removing everything from this cabinet will give you the space you need to disconnect the necessary components.
2. Disconnecting The Venting (If Applicable)
Many over-the-range microwaves come configured for recirculation, meaning they don’t require external venting.
However, if your microwave is vented through the wall or ceiling, you’ll need to locate and unscrew the metal duct that connects from the top of the microwave to the damper assembly. This will allow you to fully detach the microwave.
3. Unplugging The Microwave
Once the upper cabinet is clear, follow the microwave’s power cord to the electrical outlet and unplug it from the power source.
4. Unscrewing The Bolts
Your over-the-range microwave is secured in place with two bolts that screw through the bottom of the cabinet and into the top of the microwave.
With the help of a second person to support the weight of the microwave, use an electric drill or screwdriver to remove these bolts.
5. Rotating And Removing The Microwave
Continuing to work with a partner, slowly rotate the microwave downward, angling the top of the appliance toward you. Lift the microwave off the mounting plate and set it aside on a protected surface.
6. Removing The Mounting Plate
The final step is to locate and remove the screws or bolts holding the metal mounting plate to the wall behind the microwave. This plate is typically secured at each of the four corners.
Once the screws are out, you can set the mounting plate aside. With the over-the-range microwave now fully removed, you’re ready to move on to installing your new range hood.
Installing The Over The Range Microwave: Step By Step
Now that you’ve successfully removed your over-the-range microwave, it’s time to install your new range hood.
This process involves several steps to ensure proper ventilation and electrical connections, so it’s best to work with a partner for most of these tasks.
1. Choosing The Range Hood Placement
The first step is to determine the ideal placement for your new range hood. Many range hoods come with a paper mounting template that can guide you in finding the best spot for the vent hole.
Measure the center point of the wall where you want to install the hood, then tape the template in that location and mark the spot for the vent hole.
2. Inspecting The Vent Location
Before cutting the full vent hole, use a utility knife to remove a small section of drywall and inspect the wall for any plumbing or electrical lines that could interfere with the ventilation.
If you discover any obstructions, you may need to enlist the help of a professional to reroute the vent location.
3. Cutting The Interior Vent Hole
Once you’ve confirmed the vent path is clear, use an oscillating tool or reciprocating saw to cut the interior vent hole. The hole should be at least 6 inches wide, but a larger opening will provide better visibility during installation.
After cutting the hole, drill four locator holes around the edges to help you create a matching exterior vent hole.
4. Preparing The Exterior Vent Hole
On the exterior of your home, use the four locator holes to guide the cutting of the exterior vent hole. For homes with smooth siding, connect the locator holes with your saw and cut the opening.
Apply caulk to the inner lip of the vent cap, position it in the hole, and securely screw it in place before caulking around the exterior edge.
If your home has lap siding or an uneven exterior, you’ll want to cut a square of siding around the vent hole and install a square piece of PVC trim with a pre-cut vent opening. Secure the vent cap to the trim using caulk and screws.
5. Connecting The Damper (If Applicable)
Some range hoods include an interior damper that attaches to the vent hole and connects to the exterior damper through ducting.
Measure the space between the interior and exterior dampers, cut the necessary length of ducting, and tape it securely to the interior damper.
6. Connecting The Wiring
Range hoods typically require hard-wiring instead of a simple plug-in connection. If your kitchen isn’t already set up for this, you’ll need to schedule a service with a licensed electrician to complete the wiring.
7. Securing The Range Hood
With the help of a partner, position the range hood in place so the damper and ducting are secured within the vent hole.
Remove the grease filter to make it easier to access the mounting screws. Start by tightening the upper screws first, ensuring the hood is level and properly positioned before fully securing it.
8. Finishing The Wiring
Refer to the installation instructions for your specific range hood model to complete the wiring process. If you’re not comfortable working with electrical connections, it’s best to have a professional electrician handle this step.
9. Completing The Installation
Reassemble any removable components like filter screens, vent covers, or the vent fan. Turn the power back on and test the range hood to ensure it’s functioning correctly.
With the new range hood now installed, you’re ready to enjoy improved ventilation and air quality in your kitchen.
Considerations for Range Hood Height
When replacing an over-the-range microwave with a range hood, it’s important to consider the available space above your cooking surface. Range hoods come in a variety of sizes to accommodate different kitchen layouts.
Tall Vent Hoods
Wall-mounted and island-style range hoods tend to be taller, typically ranging from 24 to 29 inches in height. These larger hoods are great for providing powerful ventilation in spacious kitchens with ample clearance above the stove.
Short Vent Hoods
If you’re working with a smaller kitchen or have limited space above your cooking surface, shorter range hood styles like under-cabinet or insert models may be a better fit.
These compact hoods generally measure between 4 to 18 inches tall, making them a more discreet option for kitchens with lower ceilings or limited clearance.
Conclusion
Replacing an over-the-range microwave with a dedicated range hood can be a smart upgrade for your kitchen.
Not only do range hoods typically offer more powerful ventilation capabilities, but they can also enhance the overall aesthetic of your cooking space.
By carefully following the steps to remove your existing microwave and install a new range hood, you can enjoy improved air quality, better cooking performance, and a more streamlined kitchen design.
