Our take
Sharp R-409YK is a black countertop microwave with a 1.3-cu.-ft. stated cavity, 1,000-W microwave output and eleven power levels. Its exact manual lists 1,400 W input separately, specifies a grounded 120-V / 60-Hz supply, and gives installation clearances. The exact R-409YK listing gives a 12-7/8-in. turntable and says sensor cooking and an optional built-in trim kit are absent. The historical Amazon candidate mapping remains unverified; use the tagged full-model search.
Compare R-409YK for a black 1.3-cu.-ft. counter microwave with timed and preset controls; choose a confirmed sensor model when that feature is essential, and measure the tray and counter clearances first..
Choose another documented model if sensor cooking, a trim-kit installation, or at least 1.5 cu. ft. is a hard requirement. Confirm the actual dish base, rotation clearance, outlet and counter space before purchase.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Sharp's exact manual distinguishes 1,000-W microwave output from 1,400-W input and confirms U.S. 120-V / 60-Hz supply.
- Eleven levels plus Auto Cook, One Touch Cook, time and weight defrost, and +30-second start provide several documented control routes.
- The exact-model record provides a 12-7/8-in. turntable figure, while the manual supplies cavity and exterior dimensions for fit checks.
What to weigh up
- A 1.3-cu.-ft. cavity does not satisfy a 1.5-cu.-ft. hard minimum, even though it is larger than a 1.2-cu.-ft. preference threshold.
- The exact R-409YK listing reports no sensor cooking and no optional trim kit; its automatic menus should not be mistaken for sensing.
- The historical candidate ASIN has no verified exact-model crosswalk, and the exact surface material is not stated in the reviewed sources.
The key details
| Model covered | R-409YK |
|---|---|
| Capacity | 1.3 cu. ft. capacity; the exact manual lists 15.0 x 9.7 x 15.2-in. cavity dimensions and 22.2 x 12.5 x 16.4-in. outside dimensions. |
| Microwave output | 1,000 W microwave energy output; the same manual lists 1,400 W input power, a separate electrical-consumption figure. |
| Cooking approach | Eleven power levels, Auto Cook, One Touch Cook, time and weight defrost, and +30-second start are documented; the exact-model listing says no sensor cooking. |
| Installation options | Countertop placement on a level surface; allow about 3 in. at the sides and rear and about 4 in. above. The manual specifies a grounded 120-V / 60-Hz supply; no optional trim kit is listed. |
| Finish and turntable | The manual's K color suffix identifies black. The exact R-409YK listing gives a 12-7/8-in. turntable; exact surface finish and material remain unspecified. |

What the features mean for you
Which R-409Y code does the manual identify?
The Sharp-authored operation manual describes models as R-409Y followed by a color letter and identifies K as black. That supports the exact R-409YK identity and the black color, while leaving the surface coating and material unspecified. Keep the extra A in R-409YKA as a meaningful model-code difference; its separate sheet is not evidence for this unit's turntable, controls, or other specifications. This distinction matters when checking an older microwave listing because similar family names do not establish the same exact product. Match the full code printed on the unit rather than relying on a cropped title or a color photograph.
Will its cavity and tray fit your dishes?
The manual states 1.3 cu. ft. and gives interior dimensions of 15.0 by 9.7 by 15.2 inches. The exact R-409YK product listing gives a 12-7/8-inch turntable. Those figures help narrow a fit check, but cavity volume is not the same as a flat platter's usable width: a dish base must sit on the tray and rotate without touching the walls. Measure your everyday plate or container and compare it with the tray and cavity opening. The stated capacity clears the finder's 1.2-cu.-ft. preference, but it does not meet the 1.5-cu.-ft. hard threshold for larger dishes.
How should the two wattage figures be read?
Sharp's exact manual lists 1,000 W as microwave energy output and 1,400 W as input power. Use the output figure when comparing stated cooking output; use the input and nameplate information when checking electrical demand. They describe different parts of the appliance and should not be swapped in a comparison. The manual's installation guide calls for approximately 12 A at 120 V / 60 Hz and a grounded outlet. It does not make an output-watt claim a promise about a meal's heating time. Confirm the actual outlet, grounding, circuit and nameplate at the counter before connecting the oven.
What cooking guidance is actually documented?
The manual's control diagram names Auto Cook, One Touch Cook, time defrost, weight-defrost pads, power selection and a Start / +30 Seconds key; the specification page lists eleven power levels. These options can reduce repeated keypad entry for common tasks while leaving timed and power-level cooking available. They are not evidence of sensor cooking. The exact R-409YK listing explicitly says Sensor Cooking: No, so choose a sensor-confirmed model if you want the appliance to adjust cooking from measured steam or moisture. R-409YK is a better fit for someone content to select presets or manage time and power directly.
How much counter and electrical space does it need?
The manual says to place the oven on a level, flat surface, keep vents clear, allow three inches between the sides and rear and nearby surfaces, and leave about four inches of open space above. That clearance can rule out a tight shelf even when the 22.2-inch exterior width fits. The same guide specifies a grounded 120-V / 60-Hz outlet and approximately 12 A. The exact R-409YK listing does not identify an optional built-in trim kit, so plan on countertop use rather than assuming a cabinet conversion. Check your counter depth and ventilation path as well as width.
How should you compare listings and alternatives?
The source row's historical ASIN B007ZL17CC was not verified as an exact current R-409YK offer. The shopping destination therefore searches the complete Sharp model code and carries the buyershortlists-20 tag; it is not a direct product-link claim or a statement about current price, condition or stock. Compare any result's printed model code and black variant with the manual. If sensor cooking is more important than a slightly larger stated cavity, the already documented Sharp R-326FS is the more relevant comparison: it has a 1.2-cu.-ft. cavity, 1,100-W output and sensor functions. R-409YK instead offers the larger listed cavity, with no confirmed sensor or trim route.
What else to compare
For confirmed sensor cooking, compare Sharp R-326FS: its saved exact-model profile documents a 1.2-cu.-ft. cavity, 1,100-W output and sensor functions. R-409YK has a larger stated 1.3-cu.-ft. cavity and 1,000-W output but no documented sensor or trim-kit route. Decide whether cavity space or sensor guidance matters more, then measure the dish and counter clearances.
Before you buy
Is Sharp R-409YK the same model as R-409YKA?
No. The R-409YK code is identified by the R-409Y manual's K color suffix. R-409YKA is a different full model code, so do not transfer its specifications or installation details.
Does 1,000 W mean the microwave draws 1,000 W?
No. The manual lists 1,000 W microwave output and 1,400 W input power. Check the exact nameplate and grounded outlet for electrical planning.
Does R-409YK have sensor cooking?
The exact R-409YK listing says no sensor cooking. Auto Cook and One Touch Cook are documented controls, but they do not establish a sensor feature.
What size dish can use the turntable?
The exact listing gives a 12-7/8-in. turntable, but dish shape and cavity clearance matter too. Measure the base and confirm it can rotate without contact.
Can I install the microwave inside a cabinet?
The exact listing says no optional built-in trim kit, and the manual specifies open ventilation clearances. Plan for counter use unless exact installation documentation says otherwise.
Where can I check the current price?

The decision
Choose R-409YK when a black 1.3-cu.-ft. countertop microwave with eleven levels, preset controls and documented 1,000-W output fits your routine. Its sensor feature and trim-kit route are absent from the exact listing, and its historical ASIN is not confirmed; search the full model code and verify the unit label.
