How to Install a Microwave | 12 Steps

While the installation of a microwave might seem like a straightforward task, it’s important to approach it carefully to ensure safety and efficiency. Whether you’re replacing an old microwave or installing a new one for the first time, following these 12 steps will guide you through the process.

Step 1: Gather Tools and Materials

Before you start, gather the necessary tools and materials:

  • Microwave oven
  • Mounting template (if provided)
  • Measuring tape
  • Drill and drill bits
  • Screwdriver (Phillips or flathead)
  • Stud finder
  • Level
  • Pencil
  • Mounting hardware (screws, bolts, etc.)
  • Electrical outlet nearby (if not present, hire an electrician)

Step 2: Choose the Location

Select a suitable location for your microwave. It should be close to an electrical outlet and have sufficient space around it for ventilation. Avoid placing it above a gas stove unless the manufacturer specifically recommends it.

Step 3: Measure and Prepare

Measure the space where the microwave will be installed to ensure a proper fit. Check the dimensions of the microwave and compare them with the space available, allowing some extra space for ventilation.

Step 4: Locate Wall Studs

Use a stud finder to locate the wall studs in the installation area. Microwaves are typically mounted onto the wall, and attaching them to studs ensures proper support and stability.

Step 5: Install Mounting Bracket (if applicable)

If your microwave comes with a mounting bracket, follow the manufacturer’s instructions to install it securely onto the wall. Ensure it is level and firmly attached to the studs.

Step 6: Make Electrical Connections

If an electrical outlet is not already present near the installation area, contact a qualified electrician to install one. For safety, the microwave should have its dedicated circuit to prevent overloading.

Step 7: Position the Microwave

Carefully lift the microwave and position it near the installation area. Enlist the help of someone if the microwave is heavy or bulky.

Step 8: Attach Microwave to Bracket or Wall

If using a mounting bracket, carefully lift and slide the microwave onto the bracket. If not using a bracket, align the microwave with the drilled holes in the wall and attach it using appropriate screws or bolts. Ensure the microwave is level.

Step 9: Secure the Microwave

Once in place, secure the microwave by tightening the screws or bolts. Double-check its stability and ensure it is properly attached to the wall or bracket.

Step 10: Connect Electrical Supply

Carefully plug the microwave into the nearby electrical outlet. Ensure the power cord is not twisted or pinched, and the outlet is properly grounded.

Step 11: Test the Microwave

Turn on the microwave and test its functions to ensure it’s working correctly. Follow the manufacturer’s instructions for any initial setup or programming required.

Step 12: Final Adjustments

Make any necessary adjustments to ensure the microwave door opens and closes smoothly. Check for proper ventilation and clearances as per the manufacturer’s recommendations.

1. Can I Install a Microwave Over a Gas Stove?

It’s generally not recommended to install a microwave directly over a gas stove due to safety concerns. Manufacturers usually advise against it because of the heat and potential grease buildup, which could pose a fire hazard. If unavoidable, follow specific manufacturer guidelines for safe installation.

2. Do I Need a Dedicated Circuit for the Microwave?

Yes, it’s recommended to have a dedicated circuit for your microwave to prevent overloading. Microwaves draw a significant amount of power, so having a separate circuit ensures safety and prevents tripping the breaker.

3. How High Should I Install the Microwave?

The ideal height for installing a microwave above the countertop is typically between 13 to 16 inches. However, this may vary based on the manufacturer’s recommendations and the specific model of the microwave.

4. Do I Always Need a Mounting Bracket?

Not necessarily. Some microwaves come with mounting brackets for wall installation, while others can be mounted directly onto the wall using appropriate screws and bolts. Always follow the manufacturer’s instructions regarding installation methods.

5. Can I Install a Microwave Without a Ventilation System?

While many microwaves come with built-in ventilation systems, some models don’t require external venting. These are known as “recirculating” or “ductless” microwaves. However, it’s essential to follow the manufacturer’s instructions for proper ventilation, especially if your microwave has a venting system.

6. Is Professional Installation Necessary?

If you’re uncomfortable with DIY installations or if there’s any uncertainty, it’s wise to seek professional assistance. Additionally, if the installation involves electrical work or modifications beyond your expertise, hiring a licensed electrician or technician is highly recommended for safety.


Installing a microwave involves attention to detail and adherence to safety guidelines. Following these 12 steps will help you install a microwave efficiently and securely. If at any point you’re unsure or uncomfortable with the installation process, it’s advisable to seek professional assistance to ensure a safe and proper installation.
