The KoolMore KM-MOT-OP1SS is a compact 24-inch-class over-the-range microwave delivering 1,000 W into a 1.3 cu ft interior, earning a 4.3-star average from 83 buyers at a mid-range $413.55 price.
Kitchens with a 24-inch space above the range, common in smaller homes, apartments, and galley-style layouts, where a full 30-inch OTR simply won't fit. The 1,000 W output and 11 power levels make it capable for everyday cooking needs in a tighter footprint.

Cooks who regularly heat large dishes or need maximum interior room should look at 30-inch models with 1.7-1.9 cu ft capacity. At 1.3 cu ft, fitting a full casserole dish or large bowl may be tight.

Overview
At 23.85 inches wide, the KM-MOT-OP1SS fills a real gap in the OTR market: it targets the 24-inch installation space where standard 30-inch units do not fit. The 1.3 cu ft cavity and 1,000 W output are proportionate to its compact size and handle routine reheating, defrosting, and quick cooking tasks without issue.
The 11 power levels offer more granular control than many budget OTR units, which is useful for precision tasks like softening butter or melting chocolate without burning. The touchscreen control panel keeps the interface clean, and the black finish suits darker kitchen color schemes. At 57 pounds, installation requires a second set of hands and proper bracket mounting above the range.
With 83 reviews averaging 4.3 stars, the KM-MOT-OP1SS has a reasonable quality signal for a less-known brand. At $413.55, it sits at a premium compared to compact OTR competitors, so buyers should confirm no other brand offers a better-specced 24-inch unit at a lower price before committing.

Performance notes
The 1,000 W magnetron delivers standard OTR heating speed despite the compact 23.85-inch frame. The 1.3 cu ft interior comfortably fits most single-serving containers and mid-size bowls; large 9x13-inch baking dishes may be a tight squeeze. Eleven power levels give more stepping granularity than the typical 5-10 level range on budget units, which benefits tasks requiring lower sustained heat. The touchscreen panel covers standard timed cook, defrost, and power-level modes.
What buyers say
Eighty-three reviews averaging 4.3 stars is a meaningful positive signal for a compact OTR from a niche brand. The rating suggests buyers who needed a 24-inch solution found this unit performed acceptably. There is no high-volume monthly purchase data to signal broad market traction, so this remains a specialty-fit product for buyers with a specific installation constraint.
Does the KoolMore KM-MOT-OP1SS fit a standard 24-inch cabinet opening above the range?
At 23.85 inches wide, this unit is designed for 24-inch installations. However, always verify the full rough-in dimensions, height clearance above the range and depth into the cabinet, against your specific space before ordering, as installation requirements vary by kitchen configuration.
How does 1.3 cu ft compare to other over-the-range microwaves?
Standard 30-inch OTR microwaves typically range from 1.6 to 1.9 cu ft. At 1.3 cu ft, this compact unit has less interior room, which is expected for a 24-inch-class model. It fits most plates and standard-size bowls, but large casserole dishes or wide containers may not clear the walls comfortably.
Is 1,000 W enough cooking power for everyday use?
Yes. One thousand watts is the standard output for most over-the-range microwaves and handles reheating, defrosting, and basic cooking tasks at a normal pace. It is only notably slower than 1,100-1,200 W units on large portions, which matters more for high-volume family cooking than for one or two people.
