8 Step-by-step Guidelines on How to Install a Built in Microwave Oven
Step 1: Measure the Space
The first step in installing a built-in microwave oven is to measure the space where it will be installed. Begin by identifying the designated area in your cabinetry or wall. Using a tape measure, carefully record the width, height, and depth of the space to ensure it aligns with the dimensions of your chosen microwave model. Leave additional room for ventilation as specified in the manufacturer’s guidelines.
Accurate measurements are essential for a secure fit and to avoid any modifications to your cabinetry later in the process. Double-check your measurements to ensure accuracy before proceeding to the next step.
Step 2: Prepare the Installation Space
Once you have your measurements, it’s time to prepare the installation space. Begin by removing any shelves or obstacles from the designated area in your cabinetry or wall. You may also need to adjust or remove any panels that are preventing a proper fit for the microwave.

Next, check that the power source is located nearby and easily accessible for electrical connections. If not, you may need to hire an electrician to install a new outlet.
Step 3: Install Upper Cabinets (If Necessary)
If your chosen microwave model requires upper cabinets for support, now is the time to install them. Follow the manufacturer’s instructions provided with your cabinets, making sure they are level and securely attached to the wall.
The microwave will be mounted onto these upper cabinets, so it’s essential to ensure they are level and sturdy.
Step 4: Install the Mounting Bracket
Using your drill and appropriate drill bits, create holes in the wall or cabinetry for the mounting bracket. Refer to the manufacturer’s instructions on where to place these holes.
Once the holes are created, attach the mounting bracket using screws. Make sure it is secure and able to hold the weight of your chosen microwave model.
Step 5: Prepare Microwave for Installation
Before installing the microwave, remove any packaging material and accessories from inside. Carefully read through the manufacturer’s installation instructions before proceeding. Some models may require additional steps such as attaching a trim kit or ventilation system.
You may also need to adjust the position of the feet or installation brackets on the microwave to ensure a proper fit.
Step 6: Install the Microwave
With the help of another person, carefully lift and place the microwave onto the mounting bracket. Make sure it is level and securely attached.

Double-check that all electrical connections are properly made according to manufacturer’s instructions.
Step 7: Test and Adjust
Plug in your microwave and test if it is functioning correctly. If necessary, make any adjustments such as leveling or tightening screws for a secure fit.
Make sure to also test any additional features such as convection cooking or grilling functions, if applicable.
Step 8: Finish Installation
Once you are satisfied with the placement and functionality of your built-in microwave, finish the installation by attaching any trim kits or ventilation systems according to manufacturer’s instructions.
