Our take
R-402JW is a white 1.4-cu.-ft. Sharp countertop model with 1,100-W output and a 14 1/8-in. turntable. AJ Madison's exact R402JW record and Sharp's family manual distinguish the JW suffix from R-402JWT. The manual separates 1,600-W input from microwave output and lists 120 V / 60 Hz. AJ Madison documents eleven levels, six cooking options, four defrost choices, Minute Plus and child lock, and reports no sensor cooking. Sharp's family material describes an optional trim-kit route, which requires exact kit and opening confirmation. The historical B0002ATFCW page failed, so use an exact-model search.
Check the 14 1/8-in. tray against dishes and confirm the 120-V/60-Hz supply and 1,600-W input. The optional family trim route requires exact kit and cabinet-opening confirmation for R-402JW..
Choose another model if you require sensor cooking, at least 1.5 cu. ft., verified foodservice duty or a direct link to the failed historical ASIN.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Exact R402JW evidence supports white countertop identity, capacity, output, tray diameter and no-sensor status.
- The model has eleven levels, six cook options, four defrost choices, Minute Plus and child lock.
- Sharp family material gives separate electrical ratings and an optional installation path to investigate.
What to weigh up
- The 1.4-cu.-ft. cavity is below the finder's 1.5-cu.-ft. hard minimum.
- AJ Madison reports no sensor cooking, so presets are not a substitute for a sensor requirement.
- The old Amazon page failed; the trim kit needs exact JW compatibility and opening checks.

What the features mean for you
Keep the white R-402JW code exact
AJ Madison's exact R402JW record names a white 1.4-cu.-ft. countertop Sharp, and the frozen row names R-402JW. Sharp's manual covers the related R-402J family, but suffixes still matter: do not merge JW with R-402JWT or infer that a family manual resolves an Amazon ASIN. The historical B0002ATFCW page returned an internal error. Use the tagged R-402JW search and verify the full code on an offer.
Use cavity and tray dimensions together
AJ Madison documents 1.4 cu. ft., and Sharp's family manual gives a 14 1/8-in. turntable system. The tray dimension is more concrete than capacity alone when checking a dinner plate or casserole dish. Measure the exact dish and check the interior, because the turntable must rotate freely. The cavity is below the finder's 1.5-cu.-ft. hard minimum even though it is larger than many compact models.
Compare output, input and controls without conflating them
The family manual specifies 1,100-W microwave output and 1,600-W electrical input, with 120 V / 60 Hz supply. AJ Madison lists eleven power levels, six cooking options, four defrost choices, Minute Plus and child safety lock. Output is the cooking figure; input belongs to electrical planning. These controls give the model manual and preset choices, but the retailer explicitly reports no sensor cooking.
Use the model-specific sensor limit honestly
AJ Madison states that R402JW does not have sensor cooking. That supported negative excludes it when sensing is a requirement. Manual controls and preset options do not change that conclusion: user-selected programs and sensor-based adjustment are different functions. Buyers who want automatic sensing can compare GE Profile PEB9159DJBB, which documents a sensor, and consider its larger cavity and convection features separately.
Treat the trim-kit route as optional installation
The saved Sharp family documentation describes a built-in trim-kit option while also supporting countertop placement. This is a separate installation choice, not evidence that R-402JW must be built into cabinetry. Verify the exact kit number and opening dimensions for the JW suffix before planning that route; the evidence does not justify treating every R-402J-family kit as interchangeable. Countertop use remains the primary fit.
Use the tagged search until an exact offer is proven
The exact AJ Madison record supports the white R402JW model, but the old Amazon page for B0002ATFCW failed. That means the candidate ASIN does not support a direct link or confirm current seller, condition or package. Search the full model code and check it on the listing. The family manual is useful for electrical and installation context but does not turn related suffixes into the same marketplace item.
What else to compare
GE Profile PEB9159DJBB reaches the 1.5-cu.-ft. threshold and documents sensor cooking, but adds convection features and optional trim kits. Sharp R-402JW offers a large 14 1/8-in. tray and 1.4-cu.-ft. cavity without sensor. Choose by actual dish diameter and whether sensor cooking is essential; the large tray does not replace the capacity requirement.

The decision
R-402JW is a white 1.4-cu.-ft. countertop Sharp with 1,100-W output, a 14 1/8-in. tray and no sensor cooking. The family manual lists 120 V / 60 Hz and 1,600-W input. It falls short of the 1.5-cu.-ft. requirement, and the optional trim route needs exact kit confirmation. Use the tagged exact-model search because the historical ASIN is unverified.
