Our take
Sharp R-230KK is a black 0.8-cu.-ft. countertop microwave with 800-W output, eleven power levels, weight defrost, and a 10.75-in. turntable. Sharp's service documentation distinguishes R-230KK from the white R-230KW and gives 120 V/60 Hz plus separate 1,170-W consumption. The frozen title's R230KK code conflicts with an unsupported structured R230KKW clue; this review follows the exact title code and keeps the extra W unresolved. The old ASIN was not confirmed as a current exact offer, so use the tagged R-230KK search.
Compare R-230KK for a black compact household model with eleven levels and a 10.75-in. tray; choose a larger sensor model when dish room or automatic sensing is essential..
Choose a roomier model for wide plates, a 1.2-cu.-ft. preference, or a 1.5-cu.-ft. hard minimum; do not choose this Sharp when a documented sensor or trim-kit feature is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The Sharp service manual separates 800-W microwave output from 1,170-W electrical consumption and identifies the exact R-230KK code.
- The exact-model product record documents a 10.75-in. tray, eleven power levels, and weight-defrost and automatic cooking choices.
- Sharp's official family manual identifies the R-230K series as a home-use appliance and gives a 120-V/60-Hz supply context.
What to weigh up
- A 0.8-cu.-ft. cavity and 10.75-in. turntable leave less room for broad cookware than the 1.1- to 1.6-cu.-ft. models in this batch.
- The exact reviewed materials do not confirm sensor cooking or a compatible trim kit, so those needs require a different documented model.
- The source row's structured R230KKW string is not supported as an alias, and historical ASIN B000UVHTTE is not an exact-link proof.
The key details
| Model covered | R-230KK |
|---|---|
| Capacity | 0.8 cu. ft. capacity with a documented 10.75-in. turntable; check dish base and rotation clearance separately. |
| Microwave output | 800 W nominal microwave output under the stated IEC procedure; 1,170 W power consumption is a separate electrical figure. |
| Cooking approach | Eleven power levels, weight defrost, and automatic cooking and reheating choices are documented; sensor cooking is not confirmed. |
| Installation options | Countertop home-use model with 120 V / 60 Hz supply; the reviewed exact sources do not document an optional trim kit. |
| Finish and turntable | Black R-230KK code, kept distinct from white R-230KW; the conflicting structured R230KKW clue remains unresolved. |

What the features mean for you
Which Sharp code does the evidence support?
The frozen title identifies R230KK, and Sharp's service manual lists R-230KK separately from R-230KW. The saved product record associates R230KK with the black countertop model, while the white model has its own KW suffix. The structured field's added W does not have supporting documentation, so it remains an unresolved clue instead of a second model name. Use the hyphenated R-230KK code when checking the unit or an Amazon result. This boundary matters because a finish suffix can identify a different product configuration, not a harmless spelling variation.
How small is the cooking space?
The exact-model record lists a 0.8-cu.-ft. cavity and a 10.75-inch turntable. That is useful context for small everyday dishes, but it does not mean every 10.75-inch dish will fit or rotate; rim shape, height, and the interior opening still matter. Measure the base of a plate and leave clearance around it on the glass tray. If a wide casserole or larger serving plate is routine, compare a bigger cavity before choosing. The model does not meet this finder's hard 1.5-cu.-ft. large-cavity condition.
What do the power figures describe?
Sharp's service manual lists 800 watts of nominal RF microwave output under its IEC test procedure, then gives 1,170 watts of power consumption. Keep those numbers in their separate roles: the first is the cooking-output comparison, while the second is the electrical consumption figure. The same model-family documentation states 120 volts and 60 hertz for U.S. supply compatibility. Check the actual nameplate, grounded outlet, and circuit requirements at the installation point. Do not use output watts as a circuit rating or assume that two different wattage labels measure the same thing.
What kind of cooking guidance is documented?
The saved exact-model record lists eleven power levels, weight defrost, and several automatic cooking and reheating choices. Those options can shorten routine keypad entry and give the household a few preset routes, but they do not establish a sensor system. Sharp's reviewed materials do not identify sensor cooking for R-230KK, so the matching value remains unknown. If sensor cooking is a must, select a model whose exact manual names sensor cook or sensor reheat. If you prefer to set a time and power level yourself, the documented range of levels gives a manual route.
What installation and supply details should be checked?
Sharp's operation manual describes the R-230K family as a home-use Carousel microwave and supplies grounded household electrical instructions. It supports the model's countertop role and the documented 120-V/60-Hz profile, but no exact R-230KK trim kit appears in the sources reviewed here. Keep the unit on an open counter and consult the model label and manual for clearances, grounding, and circuit needs. A home-use classification also means the source does not qualify this model for a foodservice-only requirement.
How should an Amazon result be matched?
The saved candidate ASIN B000UVHTTE did not verify an exact current R-230KK mapping, and the structured code conflict makes loose matching especially risky. The purchase link therefore searches the full Sharp R-230KK model code with the buyershortlists-20 tag. Compare the code, black finish, and countertop description on any result rather than accepting an R-230KW white model or another R-230 family unit by name alone. The search is a shopping destination, not proof of today's price, stock, condition, or seller package.
What else to compare
Haier MWM11100TB steps up to a 1.1-cu.-ft. cavity, 1,000-W output, and a 12.4-in. tray with documented 120-V/60-Hz supply, while Sharp R-230KK is the smaller 0.8-cu.-ft. black option with 800-W output and a 10.75-in. tray. Compare dish fit and desired cooking power; neither reviewed profile establishes sensor cooking or trim-kit support.
Before you buy
Is the R-230KK the same model as R-230KW?
No. Sharp's service manual lists R-230KK and R-230KW as distinct model codes, matching the black and white identity boundary.
What is the microwave output?
Sharp lists 800 W nominal microwave output and separately lists 1,170 W of power consumption.
What is the turntable diameter?
The exact R230KK model record lists a 10.75-in. turntable; check the dish base and rotation clearance.
Does the reviewed documentation confirm sensor cooking?
No sensor feature was confirmed in the exact sources reviewed; automatic menus are not counted as sensor cooking.
Can I use B000UVHTTE as the direct link?
No exact current mapping was established, so use the tagged exact-model search and verify R-230KK on any result.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
Choose Sharp R-230KK when a black, 0.8-cu.-ft. household microwave with eleven levels, weight defrost, and a 10.75-in. tray matches your dishes. Its 800-W output and 120-V/60-Hz supply are documented; sensor cooking, a trim kit, the structured extra W, and the historical ASIN mapping are not.
