Our take
KitchenAid KCMS2255BSS is a documented large-cavity countertop microwave with a genuine built-in option. The exact-code specification page ties its 2.2-cu.-ft. capacity, 1,200-W cooking output, 16 3/8-in. recessed turntable, sensor cooking and 27-/30-in. trim-kit compatibility to this code; the KitchenAid family manual names the same model and explains how its humidity sensor works. It can be used on a counter without a trim kit, but a cabinet installation needs the right kit and cutout. Exact-code sources give different counts for sensor cycles, so the recommendation relies on the feature's presence rather than the number of quick-touch programs. The model's foodservice classification remains unconfirmed, and the historical Amazon ASIN did not load.
A higher-capacity countertop choice when sensor cooking or an optional 27-/30-inch built-in route is useful; decide the location first, then check the full dimensions, kit and cutout requirements before buying accessories..
Do not select it if the 24-in. width or cabinet opening cannot be accommodated, or if manufacturer-confirmed commercial duty is required. A trim kit is optional equipment, and a search result does not verify the old Amazon ASIN. The three-versus-six sensor-cycle count remains unsettled.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact KCMS2255BSS specification page states 2.2 cu. ft., 1,200-W cooking output and a 16 3/8-in. recessed turntable.
- The exact model has documented sensor cooking; the KitchenAid manual describes humidity detection and sensor/non-sensor menu choices.
- The product remains a countertop microwave without cabinet work and has a documented optional 27-/30-in. trim-kit route.
- The manual and exact-code listing provide concrete dimensions and electrical requirements for planning.
What to weigh up
- A 24-in. width and nearly 20-in. depth require a large, measured placement area.
- Built-in use needs a compatible trim kit, correct cutout and separate installation; it is not implied by countertop placement.
- The exact-code listings conflict on whether there are three or six sensor cycles, so no cycle-count advantage is claimed.
- No reviewed source classifies this model for commercial or foodservice duty, and the old Amazon ASIN failed.

What the features mean for you
Keep the black-on-stainless KCMS2255BSS variant exact
KitchenAid's model-family manual lists KCMS2255BSS with the KMCS3022GSS and KMCS3022GBS microwave models. Lowe's exact-code page identifies KCMS2255BSS as a black-on-stainless 2.2-cu.-ft. countertop microwave. Keep this model code attached to that appearance and its own specifications; do not transfer details from the KMCS3022 siblings or treat the historical ASIN B00F5DS02C as proven because its page returned an internal error. The exact-code appliance page is the source for model-specific capacities and options, while the KitchenAid manual documents the shared operating approach.
Match its substantial cavity and recessed platter to your dishes
The exact-code listing gives 2.2 cu. ft. capacity and a 16 3/8-in. recessed turntable, plus outside dimensions of 24 in. wide × 12 9/16 in. high × 19 5/8 in. deep. The turntable measurement is more helpful than capacity alone when checking a large plate, but it still does not guarantee every dish clears the cavity or door. Measure the intended counter and the cookware used most often. The manual also asks installers to preserve ventilation space at the rear and sides.
Sensor cooking is present, while the cycle count is unresolved
The exact-code specification page marks Sensor Cook “Yes,” and the KitchenAid manual explains that a humidity sensor detects moisture released from food and adjusts cooking time. Its quick menu distinguishes sensor choices from nonsensor programs. However, the exact-code appliance page lists six sensor cycles while Lowe's KCMS2255BSS overview lists three. Keep sensorCooking true, but do not claim a specific number of sensor programs or promise an outcome for a particular food.
Use the countertop option or plan a separate kit installation
This model is identified as a countertop microwave and may also accept an optional built-in trim kit. The exact-code specification page describes 27- or 30-in. kits and links a KCMS2255BSS trim-kit instruction file; that document names kit models MK2227/MK2220, gives cabinet cutout requirements and specifies a grounded 120-V/60-Hz/15- or 20-A supply. The microwave itself is not the trim kit. Choose the intended location, kit and opening as one fit decision; the manual says the counter configuration remains an available placement.
Leave foodservice duty and the old Amazon mapping unclaimed
The KitchenAid manual discusses home microwave operation and says the type is not designed for industrial or laboratory use, but that statement does not establish a foodservice rating. The historical Amazon B00F5DS02C page returned an internal error; use the tagged full-model search and check that a result names KCMS2255BSS rather than a related KMCS3022 variant.
What else to compare
If the electrical or duty requirement is for foodservice, compare the Amana Commercial RCS10DSE roster entry, which has a manufacturer-classified commercial rating, and confirm its smaller cavity and separate installation needs. For household use where a 2.2-cu.-ft. cavity and trim-kit choice matter, KCMS2255BSS is the documented larger option; measure the chosen counter or cutout first.
Before you buy
Is KCMS2255BSS still usable as a countertop microwave?
Yes. The exact-code specification page identifies countertop style, and its optional trim-kit pathway is separate from countertop placement.
How much room and turntable space does it have?
The exact-code page lists a 2.2-cu.-ft. cavity, a 16 3/8-in. recessed turntable and outside dimensions of 24 × 12 9/16 × 19 5/8 in.
Is sensor cooking confirmed?
Yes. The exact-code specification page marks Sensor Cook as present, and the KitchenAid manual explains humidity-based sensor cooking. The sources disagree on the number of sensor cycles, so no count is assigned.
Does it include a trim kit?
The microwave code supports optional 27- or 30-in. trim-kit installation, but the kit is a separate accessory. Follow the linked installation instructions for the selected kit and cabinet opening.
Is it classified for commercial kitchen use?
No commercial or foodservice classification is confirmed in the reviewed sources; the professional-duty value remains unknown.
Can B00F5DS02C be linked directly to Amazon?
No. Its historical page returned an internal error. Use the tagged exact-model search and verify the complete KCMS2255BSS code.
Where can I check the current price?

The decision
KitchenAid KCMS2255BSS is a black-on-stainless 2.2-cu.-ft. countertop microwave with 1,200-W cooking output, ten power levels, sensor cooking, a 16 3/8-in. recessed turntable and optional 27-/30-in. trim-kit compatibility. It measures 24 × 12 9/16 × 19 5/8 in. and requires a measured counter or cabinet opening. The sensor-cycle count differs between exact-code retailer records, commercial duty is unconfirmed, and the historical Amazon ASIN failed; use the tagged model search rather than a direct ASIN link.
