What Is a Low Profile Whirlpool Microwave?
A low profile over-the-range microwave is designed to occupy less vertical space than a traditional model. Instead of the typical 17-inch height, many low profile units measure closer to 10 or 11 inches tall. This reduced height creates more room between the microwave and the cooktop surface, which is especially helpful in kitchens with limited vertical clearance or tall cabinet installations.
Whirlpool’s low profile models maintain full cooking capacity and ventilation power despite their shorter stature. They typically offer similar wattage, turntable size, and airflow ratings as standard models. The main difference is the form factor and the mounting geometry, which requires careful attention during installation.
These units are ideal for kitchens where a standard microwave would sit too close to the cooking surface, potentially violating clearance guidelines or making large pots and pans difficult to use. They are also popular in remodels where cabinet heights are fixed and cannot be adjusted.
Tools and Materials Needed
Gathering the right tools before you begin will make the installation smoother and safer. Most of the items below are common household tools, but a few specialized items may need to be purchased or borrowed.
- Power drill with drill bits and screwdriver bits
- Stud finder
- Level, preferably a 2-foot or longer
- Tape measure
- Pencil for marking
- Phillips and flathead screwdrivers
- Adjustable wrench or socket set
- Utility knife
- Safety glasses and work gloves
- Step ladder or sturdy stool
- Duct tape or foil tape for venting
- Voltage tester
- Helper for lifting and holding the unit
You will also need the installation hardware included in the box, which typically consists of a mounting bracket, template, screws, toggle bolts for drywall, and a grease filter. Keep the manual nearby throughout the process, as model-specific details can vary.
Safety and Preparation
Safety should always come first when installing any appliance that involves electricity and heavy lifting. Before you do anything else, turn off the circuit breaker that supplies power to the microwave outlet. Use a voltage tester to confirm that no power is flowing to the receptacle.
Clear the area around the cooktop and remove any existing microwave or range hood. If you are replacing an old unit, disconnect it carefully and have a helper assist with lowering it from the wall. Never attempt to remove or install a microwave alone, as these units can weigh 50 pounds or more.
Protect your cooktop surface with a blanket or cardboard to prevent scratches during installation. Remove any cookware, utensils, and decorations from the surrounding area. Good lighting and a clear workspace will reduce the risk of mistakes and injuries.
Measuring and Planning the Installation
Accurate measurements are the foundation of a successful installation. Start by measuring the width of the opening above your cooktop. Most low profile Whirlpool microwaves are designed to fit a standard 30-inch opening, but you should verify this against your specific model’s specifications.
Next, measure the vertical clearance. The bottom of the microwave should sit at least 13 to 16 inches above the cooktop surface, depending on local codes and manufacturer guidelines. The top of the unit should have adequate clearance to the cabinet bottom, usually at least 1 inch for proper airflow.
Locate the wall studs using a stud finder. Mark their positions clearly, as the mounting bracket must anchor into at least one stud, and preferably two. If studs do not align with the bracket holes, you will need to use heavy-duty toggle bolts rated for the weight of the microwave.
Also check the location of the electrical outlet. The outlet should be inside the upper cabinet, typically centered above the opening. If your kitchen does not have an outlet in this location, you will need to have one installed by a licensed electrician before proceeding.
Low Profile vs Standard Over-the-Range Microwaves
Understanding the differences between low profile and standard models helps you decide whether this style is right for your kitchen. The table below summarizes the key distinctions.
| Feature | Low Profile Microwave | Standard Over-the-Range Microwave |
|---|---|---|
| Height | Approximately 10 to 11 inches | Approximately 16 to 17 inches |
| Cooktop Clearance | Greater clearance above range | Less clearance above range |
| Cooking Capacity | Similar cubic footage | Similar or slightly larger |
| Ventilation Power | Comparable CFM ratings | Comparable CFM ratings |
| Installation Complexity | Slightly more precise measurements | More forgiving fit |
| Ideal Use Case | Tall cabinets or limited vertical space | Standard kitchen layouts |
As you can see, the primary advantage of a low profile unit is the increased clearance above the cooktop. This makes it easier to use large pots and reduces the risk of heat damage to the microwave’s underside. The trade-off is that installation requires more precise measurements, since there is less margin for error.

Electrical and Venting Considerations
Before mounting the unit, you need to decide on your ventilation configuration. Whirlpool low profile microwaves support three venting options: external venting through the wall or roof, recirculating venting with a charcoal filter, and horizontal venting through an adjacent wall.
External venting provides the best performance by exhausting smoke, steam, and odors outside. If your kitchen already has a duct leading outdoors, you will connect the microwave’s exhaust port to this duct using a damper and appropriate transition pieces. Recirculating venting is simpler to install but less effective, as it filters air and returns it to the kitchen.
Electrically, most Whirlpool microwaves require a dedicated 120-volt, 15 or 20-amp circuit. The outlet should be located inside the upper cabinet, typically 12 to 14 inches above the cooktop. If your outlet is in a different location, consult an electrician before proceeding.
Never use an extension cord with a microwave. The unit draws significant current, and an extension cord can overheat and create a fire hazard. If the power cord does not reach the outlet, the outlet must be relocated rather than extended.
Mounting the Template and Bracket
The mounting template is a paper or cardboard guide included with your microwave. It shows exactly where to drill holes for the bracket, top bolts, and vent duct. Tape the template to the wall and upper cabinet, aligning it carefully with your measurements.
Use a level to ensure the template is perfectly horizontal. Even a small tilt will cause the microwave to hang unevenly, which can affect door operation and cooking performance. Mark all hole locations through the template with a pencil.
Drill pilot holes at each marked location. For stud locations, use a drill bit slightly smaller than the screw diameter. For drywall-only locations, drill holes sized for the toggle bolts included with the unit. Remove the template once all holes are drilled.
Attach the mounting bracket to the wall using the provided screws or toggle bolts. The bracket should be firmly seated with no movement. Test it by pulling firmly downward. If it shifts or flexes, recheck your anchors and tighten as needed.
Installing the Microwave Unit
This is the step where a helper becomes essential. Two people should lift the microwave and align its rear hooks with the mounting bracket. Tilt the unit slightly upward at the front while lowering the rear onto the bracket, then let it settle into place.
Once the microwave is hanging on the bracket, push it back against the wall so it sits flush. Insert the top bolts through the upper cabinet and thread them into the microwave’s top mounting holes. Tighten these bolts evenly, alternating sides to keep the unit level.
Do not overtighten the bolts, as this can crack the cabinet or strip the threads. Snug them firmly by hand, then give a quarter turn with a screwdriver. Check that the microwave is level both front-to-back and side-to-side using a level placed on top of the unit.
Connect the power cord to the outlet inside the upper cabinet. Route the cord so it does not get pinched between the microwave and the cabinet. If your model includes a cord management clip, use it to secure the cord neatly.
Testing and Final Adjustments
With the unit mounted and powered, restore electricity at the circuit breaker. Open the microwave door and verify that it swings freely without hitting adjacent cabinets or the cooktop. The door should close smoothly and latch securely.
Run a short test cycle, such as heating a cup of water for 30 seconds, to confirm that the magnetron and turntable function correctly. Listen for unusual noises, which could indicate a loose mounting bolt or misaligned venting.
Test the ventilation fan on all speed settings. If you installed external venting, check outside to confirm that air is exhausting properly and the damper opens and closes without sticking. For recirculating models, verify that the charcoal filter is installed and the air returns to the kitchen cleanly.
Finally, install the grease filter and any decorative trim. Wipe down the interior and exterior with a soft cloth to remove fingerprints and installation dust. Your low profile Whirlpool microwave is now ready for daily use.
Tips and Best Practices
Following a few best practices will ensure your installation lasts for years without problems. These tips come from common installer experience and manufacturer recommendations.
- Always have a second person help with lifting and positioning the microwave.
- Use a stud finder with deep-scan capability to locate studs behind thick drywall.
- Pre-drill all holes to prevent wood splitting in the upper cabinet.
- Apply a small bead of silicone sealant around the vent duct connection to prevent air leaks.
- Keep the installation manual and template for future reference or resale.
- Check that the microwave is level before fully tightening all fasteners.
- Verify the outlet voltage matches the unit’s requirements before connecting power.
- Clean the grease filter regularly to maintain ventilation performance.
Taking these extra precautions may add a few minutes to the job, but they significantly reduce the risk of callbacks, damage, or safety issues down the road. (See Also:How To Loosen Microwave Grime)
Common Mistakes to Avoid
Even experienced DIYers can make mistakes during microwave installation. Being aware of these common pitfalls helps you avoid them.
One frequent error is skipping the template step and drilling freehand. This almost always results in misaligned holes and a crooked installation. Always use the provided template and measure twice before drilling.
Another mistake is failing to anchor the mounting bracket into a stud. Drywall alone cannot support the weight of a microwave, and toggle bolts should only be used as a secondary anchor, not the primary one. If no stud aligns with the bracket, use a mounting plate or relocate the installation.
Some installers forget to remove the shipping bolts or protective film before mounting, which can cause rattling or overheating. Always inspect the unit thoroughly before lifting it into place. Also, neglecting to test the door clearance with adjacent cabinets can lead to a microwave that cannot open fully.
Finally, attempting to install the unit alone is dangerous and often results in dropped microwaves or damaged cooktops. Always recruit a helper, even if it means waiting an extra day.
Troubleshooting After Installation
If something does not work correctly after installation, do not panic. Most issues have simple solutions. Here are the most common problems and how to address them.
If the microwave does not power on, check the circuit breaker and verify the outlet has power using a voltage tester. Ensure the power cord is fully plugged in and not pinched. If the outlet is dead, contact an electrician.
If the door will not close properly, check that the unit is level and not twisted on the bracket. Loosen the top bolts slightly, adjust the microwave, and retighten. Also inspect for packaging material stuck in the door seal.
If the ventilation fan is noisy or weak, verify that the ductwork is connected properly and free of obstructions. Check that the damper opens fully and that no screws or debris are inside the duct. For recirculating models, ensure the charcoal filter is installed correctly.
If the microwave rattles during operation, tighten all mounting bolts and check that the turntable is seated properly on its roller ring. Vibration can also occur if the unit is not level, so recheck with a level.
