Our take
Whirlpool WMC20005YW is defined by its space-saving shape rather than by a large cavity. The 0.5-cu.-ft. oven has a rounded rear for corner placement, an 11-inch plate fit, 750-W output and ten touch-selected power levels. Its 14.125-inch height deserves a careful shelf check. A tagged direct link is supported by a current exact-model Amazon page. Consider it for reheating modest portions in a tight kitchen; choose a larger model if cookware height, capacity or sensor cooking matters more.
Choose this when reclaiming counter depth matters more than cavity volume. Measure the full 14.125-inch height and leave the ventilation clearances required by the manual; the rounded rear does not mean the oven can be boxed into cabinetry. Check that an 11-inch plate is enough for the dishes used most often. The listed 120-V, 15-A supply is a model requirement, not a claim that every kitchen circuit is suitable. The source and current Amazon page both identify WMC20005YW, but the page does not establish the condition or contents of any individual offer..
Choose a larger microwave for family platters, tall cookware, sensor programs, or a lower shelf profile. This model also needs a properly grounded supply matching its listed electrical rating.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Rounded rear is designed to use a corner more efficiently.
- The 11-inch plate fit is generous relative to the 0.5-cu.-ft. cavity.
- Ten power levels, a control lock and Add 30 Seconds are documented.
What to weigh up
- The 0.5-cu.-ft. cavity and 750-W output constrain the size and pace of routine heating.
- Its 14.125-in. height can be the limiting fit dimension.
- No sensor cooking or trim-kit option is documented.
The key details
| Model covered | WMC20005YW |
|---|---|
| Capacity | Whirlpool lists 0.5 cu. ft. and dimensions of 15.375 in. W × 14.125 in. H × 13.75 in. D; the rounded rear helps it sit toward a counter corner. |
| Microwave output | Manufacturer information lists 750-W cooking power and a 120-V, 15-A electrical requirement. Treat cooking output and circuit demand as separate checks. |
| Cooking approach | The glass tray fits an 11-in. dinner plate; the compact cavity and vertical control/mechanism layout limit the height available for taller cookware. |
| Installation options | Touch controls provide ten power levels, Add 30 Seconds and a control lock. No sensor-cooking or trim-kit feature is documented for this model. |
| Finish and turntable | Whirlpool's page names white WMC20005YW, and the current Amazon page matches that exact model. The tagged direct destination does not establish offer condition or included accessories. |

What the features mean for you
Will its shape solve a counter-space problem?
Whirlpool describes the rounded back as a way to place the oven near a corner. That changes the footprint calculation: a rectangular microwave of similar capacity may leave a triangular gap behind it, while this design is intended to use that space. Measure the counter depth and nearby wall or cabinet so the rounded shell can actually reach the corner. The shape does not remove the need for airflow or make this a built-in microwave.
Does a small cavity still fit ordinary plates?
Whirlpool says the glass tray accommodates an 11-inch dinner plate. That is a helpful distinction from many sub-cubic-foot ovens, but it should not be mistaken for a tall or wide cooking chamber. A plate may rotate while a large handled vessel, a deep container or a dish near the roof does not fit comfortably. Check the height and turntable path of the actual cookware rather than selecting by capacity alone.
How does the control layout affect routine use?
The maker documents tap-touch controls, ten variable power levels, Add 30 Seconds and a control lock. Those features cover common manual tasks: lowering power for a gentler cycle, extending a short run, or preventing accidental key presses. The page does not document a humidity sensor, so a user who wants automatic adjustment should look elsewhere. This is a conventional control set, not a specialist cooking system.
What should you verify before giving it a shelf?
The published body is 15.375 inches wide, 14.125 high and 13.75 deep. The height is substantial for this capacity, and the appliance still needs the clearance specified in its manual. Rounded corners do not authorize installation inside an enclosed cupboard. Plan for the cord, door opening and hot-air path as well as the outside dimensions, and verify the exact rating plate and circuit at the intended location.
How strong is the documented heating specification?
Whirlpool lists 750 W of cooking power and a 0.5-cu.-ft. capacity. That makes the microwave compact in both output and volume; the wattage is a published rating, not a promise of a particular cooking time. The product is most plausible for drinks, snacks and smaller dishes. For frequent batch heating or a meal with several large components, compare a 1.0-cu.-ft. or larger unit with more output.
Who should select this model over another compact oven?
Its clearest distinction is the rounded back and reported 11-inch plate fit. Haier MWM0701TW is smaller at 0.7 cu. ft. and 700 W, with a documented 9.6-inch turntable; Panasonic NN-SU656B is much larger at 1.3 cu. ft. and adds sensor cooking. WMC20005YW sits between neither of those choices by volume: it is for the buyer who values corner placement and plate fit over raw capacity or automatic programs.
What else to compare
For a smaller 0.7-cu.-ft. footprint, Haier MWM0701TW lists a 9.6-inch turntable and 700-W output. Panasonic NN-SU656B offers 1.3 cu. ft., 1,100 W and sensor cooking, but needs more counter space. Compare verified cavity and feature differences rather than assuming the larger unit is automatically the better fit.
