If your cabinet opening is 36 inches wide, you may not need a 36-inch-wide microwave. The options here include standard 30-inch over-the-range models that can fit a 36-inch cabinet opening, plus side filler panels designed to cover the extra space. Measure your opening and the microwave carefully: the right choice depends on whether you need a working appliance, gap fillers, or both.
Our top appliance picks are the GE and Midea models, each about 30 inches wide. The trim kits are useful add-ons for a 30-inch microwave in a wider cabinet, but they are not microwaves themselves.

Our Picks: Best Over The Range Microwave 36 Inch Wide reviews
1. Tatuo Stainless Steel Side Panels for Filling Cabinet Gaps
This Tatuo set is a pair of stainless steel side panels, not a microwave. Each panel is listed as about 3 inches wide, 15.75 inches high, and 11 inches deep. The set is intended to help fill the side gaps when a 30-inch microwave sits in a 36-inch cabinet opening.
The panels are described as bendable by hand, with screws included for installation. That flexibility may help with positioning, but it also means you should check the dimensions and mounting approach before buying. Some users have found that the panels can provide a neat, built-in appearance, including when secured with separate adhesive tape rather than screws. Finish and material quality may not match every appliance perfectly.
Compared with buying a wider microwave, this is an accessory-only solution: you still need a compatible microwave, and the panels do not add cooking or ventilation features. It may suit a kitchen where the existing appliance works but leaves visible gaps.
Pros:
- Designed for the gap between a 30-inch microwave and a 36-inch cabinet opening
- Two panels and mounting screws are included
- Stainless steel finish can coordinate with many appliances
- Can be positioned to cover visible side spaces
Cons:
- It is a trim accessory, not a microwave
- Finish and fit may not perfectly match every appliance or cabinet
Verdict: Choose the Tatuo set if you already have a 30-inch microwave and have confirmed that these panel dimensions suit the gaps on both sides.
2. SHUJUKU 8171339 Stainless Steel Microwave Filler Kit
This two-piece filler kit is intended to close the side gaps around an over-the-range microwave. Its listed panel dimensions are 15.75 inches long, 10.83 inches wide, and 2.95 inches high, and the package includes 16 screws. The listing describes it as a fit for a 30-inch microwave in a 36-inch cabinet opening, as well as a 36-inch appliance in a 42-inch cabinet.
The stainless steel construction is intended for everyday kitchen use, and the panels are designed to create a tidier transition between the appliance and cabinetry. The listing names compatibility with Panasonic, Whirlpool, GE, and LG models, but “universal” does not guarantee a fit with every microwave. Check your appliance and cabinet measurements before ordering.
This is a practical alternative to replacing a working microwave solely because its width leaves a gap. It has less user experience information available than the Tatuo option, so pay particular attention to the dimensions and mounting requirements rather than assuming it will fit without adjustment.
Pros:
- Includes two filler panels and 16 screws
- Designed for common 30-inch microwave and 36-inch cabinet combinations
- Stainless steel construction is intended to resist rust and wear
Cons:
- Compatibility still depends on your exact microwave and cabinet measurements
- Does not include an appliance
Verdict: Consider this kit if its listed dimensions match your installation and you want a screw-mounted way to cover the side gaps.
3. GE 30-Inch Over-the-Range Microwave with 1.6-Cubic-Foot Capacity
The GE is a complete over-the-range microwave and vent combination. It measures about 29.87 inches wide, 16.12 inches high, and 15.56 inches deep, making it a potential option for a 36-inch cabinet opening when the installation requirements are met. Its 1.6-cubic-foot capacity and 1,000-watt cooking power cover routine reheating and everyday cooking.
Features include a two-speed, 300-CFM ventilation system, a charcoal filter, one-touch express cooking, and a turntable that can be switched off. The turntable-off option can help when you need to heat a larger or unusually shaped dish. The touch controls and child lock add familiar convenience, though the listed capacity is smaller than the Midea model in this guide.
At just under 30 inches wide, this microwave will leave space at the sides in a 36-inch opening. A compatible filler kit may help complete the look, but the GE does not include one. Confirm cabinet, clearance, and mounting requirements before installation.
Pros:
- Complete microwave and vent unit, about 30 inches wide
- 1,000 watts of cooking power and 1.6 cu. ft. capacity
- 300-CFM, two-speed ventilation with a charcoal filter
- Turntable-off setting and child lock
Cons:
- Smaller listed capacity than the Midea option
- Side filler panels are not included
Verdict: The GE is a sensible choice if you want a standard-width microwave with basic ventilation and controls, and its dimensions suit your installation.
4. Xccerdb Universal Side Filler Kit with Brushed Finish
This two-piece side filler set is designed to cover the gaps created when a 30-inch over-the-range microwave is installed in a 36-inch cabinet opening. The panels measure about 16 by 11 by 3 inches, and the listing describes them as a replacement for part number 8171339. The kit is described as compatible with certain Whirlpool, GE, and Maytag models.
The panels are made from titanium-plated stainless steel with a brushed finish. The listing presents this surface as resistant to fingerprints, discoloration, and everyday wear, though the appearance may differ from your microwave’s stainless steel. Screws are included, and the panels have pre-drilled holes for mounting.
Unlike a complete trim frame, this set includes side panels only. It does not include a microwave or a top-and-bottom frame, so check the shape of your opening and the amount of space you need to cover. It is a more finish-specific alternative to the Tatuo and SHUJUKU kits, but the listed compatibility is narrower.
Pros:
- Designed to fill side gaps around a 30-inch microwave in a 36-inch opening
- Brushed, titanium-plated stainless steel finish
- Pre-drilled panels and mounting screws are included
Cons:
- Side panels only; it is not a complete four-sided frame
- Listed compatibility does not cover every microwave brand or model
Verdict: Pick this kit if you want brushed-style side panels and have verified that your microwave and cabinet match its dimensions and stated compatibility.
5. Midea 1.7-Cubic-Foot Over-the-Range Microwave with Auto Menus
The Midea is a complete over-the-range microwave with a listed width of 29.9 inches, so it may suit a 36-inch cabinet opening if the installation measurements work. It offers 1.7 cubic feet of capacity and 1,000 watts of cooking power. Its 12.4-inch turntable is listed as large enough for dishes such as a 12-inch pizza.
Its main draw is a set of 18 auto menus for foods and tasks such as popcorn, pizza, defrosting, and reheating. The microwave also has 10 power levels, a touchscreen panel, a cooktop light, and a 300-CFM vent with adjustable fan speeds. These features give it more listed capacity and more named auto-cook options than the GE, while both models provide 1,000 watts and 300 CFM.
As with the GE, side filler panels are not included. The listed depth is 13.5 inches, so compare it with the available space and the installation instructions before you order. This model may suit households that value the larger stated capacity and one-touch menus over a simpler control set.
Pros:
- 1.7 cu. ft. capacity and 1,000 watts of cooking power
- 18 auto menus and 10 power levels
- 300-CFM ventilation with adjustable fan speeds
- Cooktop light and 12.4-inch turntable
Cons:
- Side gap fillers are not included
- Confirm the listed dimensions and installation fit before purchase
Verdict: Choose the Midea if you want a 30-inch-class microwave with more listed capacity and a wider set of auto menus.
How to Choose an Over-the-Range Microwave for a 36-Inch Opening
Measure the cabinet opening and the appliance
Do not shop by the keyword “36 inch” alone. Many over-the-range microwaves are about 30 inches wide, and a 36-inch cabinet opening may leave side gaps that need trim panels. Measure the opening’s width, height, and depth, then compare those numbers with the microwave’s listed dimensions and installation instructions. Also measure the gap on each side separately; cabinets and openings are not always perfectly even.
Decide whether you need an appliance or gap fillers
The products in this guide serve two different purposes. The GE and Midea are working microwaves with ventilation. The Tatuo, SHUJUKU, and Xccerdb products are side filler kits; they do not cook, vent, or replace a microwave. If your existing unit works, a compatible kit may address the appearance of a wider cabinet opening. If you need a new appliance, compare the GE and Midea first, then consider fillers only if your measurements call for them.
Check mounting and installation requirements
Over-the-range microwaves are installed above a cooktop, so confirm that the model’s installation instructions work with your cabinets and cooking area. Check the required clearance, mounting points, and available space before buying. For trim panels, see how they attach and whether the screws and pre-drilled holes line up with your installation. If you are unsure about electrical or mounting work, consider using a qualified installer.
Compare capacity, power, and controls
The GE provides 1.6 cubic feet of capacity and 1,000 watts, while the Midea lists 1.7 cubic feet and 1,000 watts. The Midea adds 18 auto menus, and the GE offers one-touch express settings and a turntable-off feature. Think about the dishes you heat most often and whether you prefer simple controls or preset cooking options.
Consider ventilation needs
Both microwave models list 300-CFM ventilation. The GE has a two-speed fan and charcoal filter; the Midea has adjustable fan speeds. Compare these features with your cooking habits and the way your kitchen is set up. The listed CFM alone does not tell you whether a particular installation will meet your needs, so consult the appliance instructions for the required venting arrangement.
Match the trim finish to your kitchen
Stainless steel can vary in shade and texture. The Tatuo and SHUJUKU panels are described as stainless steel, while the Xccerdb kit has a brushed, titanium-plated finish. Check product photos and panel dimensions, and keep in mind that a trim kit may not match your microwave exactly. A precise fit matters as much as the finish: panels that are too wide or too deep can create a poor result.
Frequently Asked Questions
Are there 36-inch-wide over-the-range microwaves in this selection?
No. The two complete microwaves listed here are both about 30 inches wide. The trim kits are meant to help cover gaps when a narrower microwave is fitted into a wider cabinet opening.
Can a 30-inch microwave fit in a 36-inch cabinet opening?
It may, but you must confirm the microwave’s installation requirements and the cabinet measurements. A 30-inch appliance can leave space at the sides of a 36-inch opening, and a compatible filler kit may help cover those gaps.
Do the trim kits include a microwave?
No. The Tatuo, SHUJUKU, and Xccerdb items are side filler panels and mounting hardware. They do not include a microwave.
Which microwave has the larger listed capacity?
The Midea lists 1.7 cubic feet, compared with 1.6 cubic feet for the GE. Actual usable space also depends on the interior layout and the size of the dishes you use.
Do the GE and Midea include side filler panels?
The supplied product information does not list side filler panels as included with either microwave. If you need to cover gaps, check the appliance package details and choose a separate kit only after confirming the fit.
How do I know whether a trim kit will fit my microwave?
Compare the kit’s dimensions with your opening and microwave, and check the listed compatibility and mounting details. Do not rely on the word “universal” alone; model, cabinet, and installation differences can affect fit.
Final Recommendation
For a 36-inch cabinet opening, the Midea is the stronger appliance choice if you want more listed capacity and multiple auto menus; the GE is a simpler alternative with a turntable-off setting and a charcoal filter. Neither is 36 inches wide, and neither listing includes side filler panels. If your microwave is already installed and only the side gaps need attention, consider the Tatuo, SHUJUKU, or Xccerdb kit after checking every measurement. The best fit is the one that matches your opening, appliance, and installation requirements—not simply the number in the search phrase.
