Our take
Sharp's exact brochure names R-216FS and lists a stainless 0.8-cu.-ft. compact microwave with 800-W cooking output, an 11 5/8-in. glass tray, six reheat options, four cook and four defrost presets, and popcorn. Its supplemental service manual gives 1,200-W input at 120 V/60 Hz. The brochure's outside depth is 13 7/8 in.; the service manual rounds this to 14 in. Model-specific parts records support countertop classification. The reviewed evidence does not establish sensor cooking, trim-kit compatibility or commercial duty. Amazon B00007KMN4 failed, so the tagged exact-model search is the supported destination. This is a review of published model specifications, not a personal-use test or shopper-review summary.
The product brochure gives 18 1/8 × 10 7/8 × 13 7/8 in.; a service-manual dimension rounds depth to 14 in. Confirm counter depth and ventilation from the full manual. Check wide dish bases against the 11 5/8-in. turntable rather than relying only on the 0.8-cu.-ft. cavity label..
Choose a larger or higher-output oven for larger dishes or heavier use, or an explicitly classified commercial model if foodservice duty is required. Do not assume sensor cooking or cabinet-kit compatibility from the presence of preset buttons.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Sharp literature specifies 0.8 cu. ft., 800-W output, stainless finish and an 11 5/8-in. turntable.
- Automatic controls include six reheat choices, four cook settings, four defrost settings and popcorn.
- Published compact body dimensions and exact-code parts records help screen for countertop fit.
What to weigh up
- The compact cavity and 800-W output limit the size and throughput use cases compared with larger household ovens.
- Electrical input is 1,200 W at 120 V/60 Hz, distinct from cooking output; the brochure/manual differ by 1/8 in. in rounded depth.
- Sensor cooking, trim-kit installation and commercial duty are unknown, and the historical exact-ASIN page did not load.
The key details
| Model covered | R-216FS |
|---|---|
| Capacity | Sharp's exact R-216FS brochure identifies the compact stainless countertop family with a 0.8-cu.-ft. cavity, 800-W cooking output and 11 5/8-in. glass turntable. |
| Microwave output | The service manual gives 1,200-W electrical input and 120 V/60 Hz separately from nominal 800-W RF output. |
| Cooking approach | Sharp documents six automatic reheat options, four cook settings, four defrost settings and a separate popcorn function. |
| Installation options | The brochure lists 18 1/8 × 10 7/8 × 13 7/8-in. dimensions; the service manual's rounded depth is 14 in. Exact-code parts records classify R-216FS as countertop. |
| Finish and turntable | Sensor cooking, trim-kit compatibility and commercial-duty classification remain unverified. Amazon B00007KMN4 did not load as exact identity proof; use the tagged full-model search. |

What the features mean for you
Read the 0.8-cu.-ft. size with the 11 5/8-inch tray
Sharp lists both a 0.8-cu.-ft. cavity and an 11 5/8-in. glass turntable. The tray is the more direct limit for a round dish base, and a dish must be able to rotate without touching the cavity wall. Measure the plate you use most before deciding that the compact cavity is sufficient.
Keep output and input ratings separate
The Sharp brochure gives 800 W cooking power, and the service manual calls it nominal RF output. The service manual separately lists 1,200 W electrical input at 120 V/60 Hz. Use the output rating to compare cooking power and the input rating when checking electrical supply; one is not a substitute for the other.
Use the presets without assuming sensor operation
Sharp documents six automatic reheat options, four cook settings, four defrost settings, and a separate popcorn function. These preset menus provide named choices for common tasks; they do not themselves prove a steam sensor or moisture-based control. The reviewed sources do not establish sensor cooking for this exact model, so keep sensorCooking unknown rather than calling the listed programs sensor functions. Follow each named program as described.
Check the compact footprint and depth rounding
The brochure gives 18 1/8 × 10 7/8 × 13 7/8-in. dimensions. The service manual rounds depth to 14 in.; that is a small source-format difference rather than proof of separate variants. Allow for door swing, cord position and ventilation beyond the case dimensions. The listed measurements describe the case, not the total clearance required for placement, so check the full installation guidance before committing counter space.
Treat countertop use as verified and cabinet use as unknown
Exact-model parts records classify R-216FS as a countertop microwave. No exact R-216FS trim-kit evidence was found, so countertop classification should not be read as permission to put the unit in a cabinet. Keep the vents exposed and follow its installation instructions. The profile therefore leaves trimKitCompatible unknown rather than calling it a confirmed no-fit. Use countertop placement unless model-specific kit evidence and instructions establish another approved route.
Use a tagged model search while duty class remains unclear
The exact Amazon page for frozen ASIN B00007KMN4 failed, so this packet does not claim that ASIN as a current matching offer. The Sharp brochure establishes the stainless model; the source has a tagged exact-model search for locating it. The reviewed manual does not classify R-216FS as household-only or commercial foodservice equipment.
What else to compare
For built-in placement, look for a model with an exact compatible trim-kit table. For foodservice, select an oven whose manufacturer states a commercial-duty classification; R-216FS's reviewed evidence leaves both attributes unresolved.
Before you buy
What is the R-216FS capacity and output?
Sharp lists 0.8 cu. ft. and 800-W nominal RF cooking output; the service manual separately lists 1,200-W input.
What turntable diameter does Sharp document for R-216FS?
The exact-model Sharp brochure lists an 11 5/8-in. glass turntable.
What preset functions are listed?
Six reheat options, four cook settings, four defrost settings and a separate popcorn function.
Does Sharp document sensor cooking for the R-216FS?
The reviewed brochure and service manual do not confirm a sensor-cooking system; preset controls alone are not enough to mark it true.
Can it be built into a cabinet?
No exact R-216FS trim-kit compatibility was verified; its countertop classification does not prove cabinet approval.
Is B00007KMN4 a verified direct product link?
No. The exact page failed; use the tagged search for Sharp R-216FS and verify the model label on the offer.
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
Sharp R-216FS is a compact stainless 0.8-cu.-ft. countertop microwave with 800-W output, an 11 5/8-in. turntable and reheat/cook/defrost presets. Sharp lists 1,200-W input at 120 V/60 Hz. Sensor status, trim compatibility and commercial class remain unknown; its historical ASIN failed exact-page verification, so use the tagged exact-model search.
