Learning how to remove a built in microwave oven is a common home improvement task that can seem daunting, but with the right preparation, it’s quite manageable. Replacing a built-in microwave begins with ensuring the appliance is completely disconnected from power. This is the single most important step for your safety before you handle any wiring or attempt to lift the unit.
Whether you are upgrading to a new model, need to perform a repair, or are renovating your kitchen, this guide will walk you through the entire process. We’ll cover everything from the tools you’ll need to the final steps of safely detaching and lowering the microwave. Following a clear, step-by-step approach will help you complete the job efficiently and avoid damage to your cabinets or walls.
How To Remove A Built In Microwave Oven
Built-in microwaves, often called over-the-range or wall oven models, are designed to fit seamlessly into your kitchen cabinetry. Unlike countertop models, they are typically secured with mounting brackets, screws, and sometimes a vent duct. The removal process involves disconnecting power, releasing these mounting mechanisms, and safely maneuvering the heavy appliance out of its space. Let’s start by gathering everything you’ll need.
Tools And Materials You Will Need
Before you start, collect all necessary tools and materials. Having everything within reach will make the process smoother and safer. You likely already have most of these items in your basic toolbox.
- A Phillips head screwdriver (size #2 is most common)
- A flat-head screwdriver
- A putty knife or thin pry tool
- A cordless drill with screwdriver bits
- A voltage tester (non-contact type is recommended)
- A helper (microwaves are heavy and awkward)
- A drop cloth or cardboard to protect your floor and countertop
- A small container or bag for holding screws
- A flashlight for better visibility
Step 1: Safety First – Disconnect The Power
This step cannot be overemphasized. You must completely cut power to the microwave to prevent the risk of electric shock. Do not rely on the microwave’s power switch; you need to disconnect it at the circuit level.
- Locate your home’s main electrical service panel (breaker box).
- Find the circuit breaker that controls the microwave’s power. It is usually a dedicated 15- or 20-amp breaker labeled “Microwave” or “Kitchen Appliance.”
- Switch the breaker to the “OFF” position.
- Go back to the microwave and press the control panel buttons to confirm it has no power. Then, use your non-contact voltage tester on the outlet behind the microwave (if accessible) or near it to double-check that the power is off.
A Note On Over-The-Range Microwave Vents
Many built-in microwaves also serve as a vent hood for your stove. They will have a duct either leading outside or recirculating back into the kitchen. As you plan the removal, note the venting type, as you’ll need to disconnect it. Check if the vent goes up through the cabinet or out the back wall.
Step 2: Prepare The Work Area
Protect your kitchen surfaces and create a clear path for removing the microwave. The appliance can be heavier than you expect, often weighing 50 pounds or more.
- Clear any items from the stovetop and nearby countertops.
- Lay down a drop cloth, old blanket, or cardboard on the range/counter below the microwave to catch dust, debris, or any small parts.
- Ensure your helper is ready to assist with supporting the weight.
Step 3: Access The Mounting Hardware
Built-in microwaves are secured from the top, bottom, and sometimes the sides or back. The mounting points are often hidden behind trim, grilles, or inside the upper cabinet.
- Open the microwave door and look for screws along the top edge of the interior or around the door frame. Some models have screws here that secure the unit to a upper cabinet bracket.
- Check the upper cabinet. Most over-the-range microwaves are bolted to a mounting bracket that is screwed to the bottom of the cabinet above. Remove any shelves or items from that cabinet. You may need to lie on the countertop to see the bracket and screws clearly.
- Look for a vent grille. On the bottom or front of the microwave, there is often a grease filter or vent cover. Remove this by pressing a latch or unscrewing it. Behind it, you might find additional mounting screws.
Step 4: Remove The Mounting Screws
With the power off and the mounting points located, you can begin removing the screws that hold the microwave in place. Have your helper support the weight of the microwave from below during this entire step.
- Using your screwdriver or drill, carefully remove all screws you found in the upper cabinet. Place them in your container so they don’t get lost.
- Next, remove any screws from inside the microwave compartment or around the door frame.
- If there is a trim kit or decorative panel around the microwave, you may need to gently pry it away with a putty knife to reveal side-mounted screws. Be careful not to damage the cabinetry.
At this point, the microwave should be loose from its mounting bracket but still resting on it. Do not let go or try to pull it out yet.
Step 5: Disconnect The Vent Duct And Electrical
Now you need to detach the microwave from the house’s venting system and its power supply. This is where your flashlight becomes very usefull.
- Vent Duct: From inside the upper cabinet, you should see where the microwave’s vent outlet connects to a duct. This is typically secured with a metal clamp or foil tape. Loosen the clamp with a screwdriver or carefully cut through the foil tape. You may need to reach behind the microwave slightly.
- Electrical Connection: Locate the power cord or electrical box. For a plug-in model, simply unplug it from the outlet (usually located inside the upper cabinet). For a hardwired model, you will see wires connected wire nuts inside a metal junction box. Carefully remove the cover of the junction box. Before touching any wires, use your voltage tester again on each wire to confirm no power is present. Then, unscrew the wire nuts and separate the microwave wires from the house wires.
Step 6: Lower And Remove The Microwave
This is a two-person job. With all screws removed and connections detached, the microwave is ready to be taken down.
- Your helper should firmly hold the microwave from the bottom, supporting most of its weight.
- Gently tilt the top of the microwave forward, pulling it away from the wall and off the mounting bracket that remains attached to the upper cabinet.
- Slowly lower the appliance straight down onto the protected stovetop or counter. Be mindful of the cord or loose wires as you lower it.
- Once it’s resting securely, you can fully remove it from the space. Carry it away carefully to avoid straining your back.
Step 7: Inspect And Prepare For Installation
With the old microwave removed, take this opportunity to inspect the space and prepare for your new appliance or to close up the opening.
- Clean the cabinet bottom and wall area of any dust or grease.
- Inspect the mounting bracket. If you are installing a new microwave of the same brand/model, the existing bracket might be compatible. Otherwise, you may need to install the new bracket that comes with your replacement.
- Check the vent duct for any blockages or damage and clean it if necessary.
- If you are not replacing the microwave, you’ll need to patch any holes in the wall and cabinet, and possibly install a proper vent hood cover for the duct opening.
Common Challenges And Troubleshooting
Sometimes, removing a built-in microwave isn’t straightforward. Here are solutions to common problems.
Stripped Or Rusted Screws
If a mounting screw is stripped or rusted and won’t turn, try these tips. Apply a penetrating oil like WD-40 and let it sit for 15 minutes. Use a screw extractor bit in your drill. If the screw head is accessible, you can sometimes grip it with locking pliers to turn it.
Microwave Seems Glued In Place
Years of grease and grime can act like an adhesive around the edges. If the microwave won’t budge after removing all screws, carefully run a utility knife along the seam between the microwave and the cabinetry to break any seal. Then, gently pry with a putty knife, alternating sides.
Unidentified Mounting Points
If the microwave is still solidly in place, you likely missed a screw. Double-check behind the grease filter, under any decorative trim on the front, and consult the installation manual for your specific model, which you can often find online by searching the model number.
Frequently Asked Questions
How Do I Remove An Over The Range Microwave By Myself?
While highly not recommended due to the weight and risk, if you must work alone, you must create a temporary support. Before removing the final screws, place a sturdy board or a stack of books on the stovetop (protected with a cloth) to act as a shelf. As you remove the last screws, the microwave will lower onto this support, giving you time to reposition and lift it down. Extreme caution is required.
Is It Hard To Take Out A Built-In Microwave?
The difficulty is moderate. The physical challenge comes from the weight and awkward positioning, which is why a helper is advised. The technical steps—finding screws and disconnecting wires—are simple with careful attention. Most DIYers can complete the task in one to two hours.
Do You Need An Electrician To Remove A Built In Microwave?
For a plug-in model, you do not need an electrician if you are comfortable turning off the correct circuit breaker. For a hardwired model, if you are unsure about safely testing and disconnecting the wires, hiring an electrician for this portion is a wise and safe choice. The physical removal can still be done by you afterwards.
What Should I Do With The Old Microwave?
Do not put it in regular trash. Microwaves contain electronic components that require special disposal. Check with your local waste management authority for e-waste recycling programs. Many appliance retailers also offer haul-away services when you purchase a new one.
Can I Replace My Built-In Microwave With A Different Brand?
Yes, but you must check the new model’s dimensions and mounting requirements carefully. The cut-out space in your cabinet may need adjustment, and you will almost certainly need to install the new mounting bracket that comes with the replacement appliance, as brackets are rarely universal between brands.
