Can I replace my own microwave?

Replacing your own microwave is definitely possible for many homeowners, but there are some important factors to consider before taking on this project yourself. In the opening section of this article, we’ll provide quick answers to common questions about replacing a microwave and discuss whether DIY microwave installation is recommended. Later sections will go into more detail on preparation, steps for removal and installation, costs, and tips for a safe and successful microwave replacement.

Is it hard to replace a microwave?

Replacing a microwave is considered an intermediate level DIY project. It requires basic electrical and carpentry skills, as well as the ability to follow installation instructions carefully. The project typically takes 2-3 hours for someone who is reasonably handy.

Can I replace a microwave myself?

Most homeowners can replace their own microwave if they are comfortable working with electricity and have basic DIY skills. You need to be able to disconnect the old electrical connections and make new ones per the installation manual for the new unit. The actual microwave swap itself is not difficult, but care needs to be taken when working with the electrical components.

Should I get a professional to replace a microwave?

A professional installation is recommended if you don’t feel comfortable working with electrical wiring. Microwave installation requires making proper electrical connections for both power and grounding. If you aren’t confident you can do this properly, hiring an electrician or appliance technician to install the new unit is worth the cost.

Is installing a microwave dangerous?

Microwave installation involves electricity, which always carries some amount of danger. Turning off the circuit breaker to the microwave before starting any work is crucial. As long as proper precautions are taken when handling the electrical components, microwave installation is not inherently dangerous for someone with experience working with electrical systems. Proper gear like insulated gloves should be used as well.

Can I install a microwave over the range?

Over-the-range microwaves need to be installed very securely, as they hang above your stove. Often the existing ventilation unit or hood just needs replacement if you already have an over-the-range microwave. In some cases cabinets or other structural components need modification to properly install and secure a new over-the-range unit. The electrical requirements are also more complex than a countertop model. Definitely hire a professional installer if you need to replace an over-the-range microwave.

Conclusion

In summary, replacing a standard countertop microwave is a DIY-friendly project for homeowners who are confident working with electrical systems. However, specialized models like over-the-range units are better left to professional installers. Doing the proper preparation is key to a smooth microwave replacement project.

Preparing for Microwave Installation

Completing the following steps will ensure you are fully ready for the task of replacing your microwave:

Pick the New Unit

Choose a replacement microwave based on your budget, available space, venting needs, and desired features. Microwaves are available in countertop, over-the-range, and built-in models. Measure the existing space carefully to find one that will fit.

Gather Supplies

You will need basic tools like a Phillips screwdriver, drill, stud finder, and tape measure. Safety gear like work gloves and eye protection are also recommended. Ensure you have all required electrical supplies for the specific microwave model per the installation manual.

Turn Off Power

Turn off the circuit breaker for the microwave before beginning any removal or installation work. Lock out and tag out the breaker to prevent accidental activation of the power while you are working.

Disconnect Old Unit

Unplug the microwave or disconnect the hardwired electrical connection. Remove any venting components attached to the back/top as needed.

Prep the Area

Have your tools, new microwave, and electrical supplies ready in the kitchen. Clear countertops or ranges to access the work area. Cover nearby surfaces with drop cloths to protect from dust and debris.

Removing the Old Microwave

Follow these steps to safely remove your existing microwave:

Disconnect Electrical

Disconnect the old hardwired power connection if present. Remove any cover panels to access wires.

Detach From Wall

Unscrew any brackets, tabs, or other fasteners securing the microwave to the wall or cabinets.

Deal with Venting

Remove any venting components like ductwork attached to the rear/top of the unit.

Lift Away

With the unit disconnected, lift it out of the installation space and off any shelves or brackets.

Remove Debris

Vacuum out the installation area to clear any dust or debris.

Check Circuitry

Inspect the existing power and ground connections for any issues. Repair if needed before installing the new unit.

Installing the New Microwave

Here are the step-by-step instructions for properly installing your new microwave:

Prep Electrical

Connect any required power/ground wires per the appliance manual for the new unit.

Insert New Unit

Lift the microwave into position on the wall or over the range. Have a second person assist to hold it in place if needed.

Secure Unit

Following manufacturer instructions, use mounting brackets, tabs, or other hardware to securely attach the microwave into the opening.

Connect Venting

Attach any required venting ducts to the rear/top exhaust opening.

Verify Operation

Restore power and test that the microwave is functioning properly.

Cost of Replacing a Microwave

If you plan to hire an appliance repair technician to replace your microwave, expect to pay:

Microwave Type	Average Cost
Countertop	$150-$300
Over-the-range	$200-$400
Built-in	$300-$600

This covers parts, labor, and supplies for a typical pro installation. Complex wiring or ductwork may increase costs. DIY replacement using a purchased microwave kit costs $100-$200 for supplies.
