The Summit Appliance MHOTR242B is a 24-inch wide over-the-range microwave built for kitchens that cannot accommodate a standard 30-inch unit. At $468 with a 1.4 cu ft interior and 1000W output, it fills a real niche, but with zero buyer reviews, there is no verified purchasing history to assess.
Homeowners with a 24-inch range or compact kitchen layout who need an OTR microwave and cannot fit a 30-inch model. The black finish and 24-inch width make it one of very few options for this installation scenario.

Overview
The MHOTR242B addresses a specific problem: over-the-range microwaves are almost universally 30 inches wide, leaving owners of 24-inch ranges with almost no purpose-built options. At 24 inches wide and 24.75 x 24 x 17.5 inches overall, this Summit unit is designed for that gap. The 1.4 cu ft cavity and 1000W output are standard functional specs, and the 12.75-inch turntable fits most everyday plates.
At 61 lb, it is heavier than a typical 30-inch unit of similar capacity, which is worth knowing for installation. The 10 power levels and touchscreen controls are what you'd expect from any competent OTR microwave, and the electric heating method is standard. Operating at 115V rather than the more common 120V is a minor distinction worth confirming against your outlet.
The real unknown here is reliability. Summit Appliance is a legitimate specialty appliance company with a focus on compact and specialty configurations, but zero reviews means buyers are purchasing entirely on specification and brand reputation. The price at $468 is elevated relative to some 30-inch models with thousands of reviews, it reflects the niche size rather than any feature premium.

Performance notes
At 1000W with 10 power levels, this unit handles routine reheating, defrosting, and cooking tasks on par with standard OTR models. The 1.4 cu ft interior is adequate for single-person or couple households but may feel limiting for families cooking large quantities. The 24-inch width is its defining feature, nothing else about the performance specs is exceptional. At 61 lb, professional or two-person installation is advisable. Dimensions of 24.75 x 24 x 17.5 inches are compact in width but relatively tall and deep.
What buyers say
There are no buyer reviews for this product. Summit Appliance carries an overall solid reputation in specialty compact appliances, but without any reviews specific to this model, there is no buyer sentiment to report. Prospective buyers are taking a real risk on the first purchase, appropriate caution is warranted at $468.
Why is a 24-inch OTR microwave so much harder to find than a 30-inch?
The vast majority of modern kitchen ranges and stoves are 30 inches wide, so OTR microwave manufacturers build almost exclusively for that standard. Compact or apartment-sized ranges at 24 inches represent a small slice of the market. Summit and a handful of other brands specifically target this gap.
Is the Summit MHOTR242B compatible with standard electrical outlets?
The unit is listed as 115V. Most US household outlets are 120V, which is within the normal tolerance range for 115V appliances. However, if your kitchen has any non-standard wiring, confirm compatibility with an electrician before installation.
Should I wait for reviews before buying this unit?
That is a reasonable approach at $468. With no buyer reviews available, you have no verified data on installation ease, cooking performance, or durability. If a 24-inch OTR microwave is the only option for your space, this may be your only choice, but if timing allows, monitoring for early reviews before purchasing is prudent.
