Mounting Under Cabinet Microwaves Made Simple

Installing an under cabinet microwave is a great way to save space in your kitchen. But getting the mounting just right can be tricky.

We'll cover everything from finding the right microwave and getting the necessary tools to drilling holes and setting up the power cord. You can also learn about alternative mounting options if you want to avoid drilling into walls. By the end, you'll have the confidence to install your under cabinet microwave like a pro!

Choosing the Best Under Cabinet Microwave

The first step is picking an under cabinet microwave that will fit your space and needs. You'll want to consider size, power, settings, and additional features:

• Size - Confirm dimensions to ensure the microwave will fit in your under cabinet space.
• Power and Settings - Make sure it can handle your cooking needs. Do you need a high-powered 1000-watt model or lower 750-watt output?
• Features - Decide if you want added functions like a turntable, mute button, child lock, etc.

We compared two popular GE under cabinet microwaves--the JEM3072SHSS and JES1072SHSS models:

GE JEM3072SHSS

• 0.7 cubic feet capacity
• 950 watts cooking power
• Optional hanging kit available for purchase

GE JES1072SHSS

• 1.0 cubic feet capacity
• 700 watts cooking power
• Mounting holes built into chassis (no need for hanging kit)

The main difference comes down to the hanging kit. The JES1072SHSS has pre-drilled cabinet mounting tabs so no additional hardware needed. It's also cheaper at $319 with ample cooking power.

The JEM3072SHSS runs about $70 more but has 250 extra cooking watts. You'd need to buy the optional mounting kit. Both allow under cabinet installation, so pick based on size, price, and features you prefer.

Preparing for Installation

Once you've selected the right under cabinet microwave, it's time to get set up for installation. Be sure you have the necessary tools, materials, and meet technical requirements:

Tools/Materials Needed

• Stud finder
• Power drill with assorted drill bits
• Hammer
• Pencil
• Screws or mounting hardware
• Level

Wiring and Ventilation Rules

You'll need an outlet to plug in the microwave. Confirm a grounded three-prong 120V, 60Hz, 15- or 20-amp outlet is present or can be installed per electrical code.

Ventilation is also key - microwaves need room around sides/top and have a rear exhaust fan. Ensure proper clearances so airflow isn't restricted. Avoid putting right next to a wall or covering vents along the top/back.

Now that we've covered preparation, let's jump into the installation steps!

Complete Under Cabinet Mounting Guide

Follow this comprehensive guide to securely wall-mount your under cabinet microwave:

1. Find Studs and Mark Holes

First, locate studs in the wall using a stud finder. Mark at least two spots over a stud to drill the mounting holes (aim for stud centers). Having screws anchored in studs ensures it can support the microwave weight.

Also mark where to pre-drill a hole for the power cord to feed through the bottom cabinet.

2. Install Mounting Plate

Align the mounting plate centered under the cabinet space. Use a level to double check. Mark pilot holes for drilling through the plate at the stud center marks.

Drill out pilot holes then secure plate to wall studs using long lag screws. The plate will have hooks, tabs, or brackets to hang microwave on.

3. Drill Power Cord Hole

Based on the bottom cabinet mark, use a 1 1/4" hole saw bit to open a hole. Feed the appliance power cord through to the outlet area.

4. Hang Microwave

Carefully lift and position the microwave so its mounting hooks, brackets, or tabs line up with support on the wall plate. For GE microwaves, slide unit in so tabs insert into chassis slots.

5. Connect and Test

Plug the power cord into the outlet, securing any slack. Turn on the microwave to verify operation and check interior light comes on when door opens.

Be sure to test open and shut the door smoothly without obstruction. Also test any cooking functions. Your under cabinet microwave should now be securely mounted and fully operational.

Alternative Mounting Options

If you're unable to drill holes into the wall, you might wonder about alternative mounting methods for under cabinet microwaves. Cabinet brackets allow installing against the bottom of upper cabinets rather than the wall itself.

This bracket approach avoids drilling into backsplashes or tiles. However, upper cabinets must be sturdy enough to support microwave weight.

Cabinet Mounting Considerations

• Ensure cabinets can handle weight load
• May need to detach and reinstall cabinet bottom
• Provides adjustment flexibility
• More expensive than wall brackets

Overall, wall mounting is the most secure DIY method. But cabinet brackets do offer another option if your situation calls for it.

Safety Tips

We received some reader questions around safety with under cabinet microwave installations, which are important to address:

Is Exposed Metal Risky?

Kelley asked: "I'm nervous about DIY mounting solutions having exposed metal screws inside. Isn't metal dangerous for microwaves and can cause issues?"

It's true that having metal components inside active microwaves risks electrical shorts and potential arcing. This is why expert mounting kits are made of plastic or non-conductive materials.

However, authorized GE hanging brackets likely meet safety standards for any enclosed or shielded metal pieces. I cannot vouch for safety of improvised machine screw mounts, so stick with proper microwave kits.
