Our take
Emerson MW1337SB is a real 1.3-cu.-ft. microwave model: Emerson's document index lists its owner's manual, the manual cover says MW1337SB/1,000 W, and an exact-code specification sheet gives 1,000 W output, a stainless front with black cabinet, touch controls, defrost, and preset recipes. The frozen source row instead spells MWG1337SB. Its size, wattage, and finish wording align with the MW1337SB specification, so I infer that the extra G is a source-row error and include MW1337SB as a distinct verified model. That inference does not establish that historical ASIN B018BA7PP8 referred to this exact model. It is not merged with Emerson MW1338SB, which is a separately documented code, and the ASIN is not used for a direct link. The sheet calls its data preliminary; the reviewed evidence does not confirm turntable diameter, humidity-sensor cooking, trim-kit support, or commercial-duty classification. This is a source-based review, not a personal test or a claim about current price, stock, or buyer-review results.
A countertop shortlist option when 1.3 cu. ft., 1,000 W stated output, touch controls, and a black cabinet with stainless front suit the space, and the exact MW1337SB identity can be confirmed on the offered unit..
Choose another model if you require a known turntable diameter, confirmed sensor cooking, a documented built-in trim kit, manufacturer-classified foodservice duty, or a direct listing proven to match historical ASIN B018BA7PP8.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact-code specification supports 1.3 cu. ft. and 1,000 W microwave output, with stainless front and black cabinet finish information.
- The listed controls include six presets, time and weight defrost, a digital clock/timer, child lockout, and an end-of-cooking signal.
- The spec sheet gives an outside footprint of 20.4 x 17.2 x 12.3 inches, useful for a measured counter-space check.
What to weigh up
- The exact specification sheet says the listed data are preliminary and may change; use the unit label and owner's manual when checking a specific appliance.
- The reviewed exact-model sources do not provide turntable diameter, confirm a humidity sensor, identify an optional trim kit, or classify foodservice duty.
- The frozen title/model field says MWG1337SB, while the independently documented product is MW1337SB; no evidence maps the historical ASIN to either code.

What the features mean for you
Keep MW1337SB distinct from the row's extra-G code
Emerson's official document index lists an owner's manual titled for MW1337SB, and the exact-code specification sheet also names MW1337SB. Its cover and specification content identify a 1,000-W microwave, while the sheet gives the 1.3-cu.-ft. capacity, black cabinet/stainless front, and touch-control feature set that resemble the frozen source title. The row itself says MWG1337SB. Because that extra G does not appear in the documents reviewed, I treat the source as likely referring to MW1337SB but keep the inference explicit. Emerson's MW1338SB product page names a different model, so MW1338SB is not an alias or a source for this packet. The historical ASIN is not mapped to MW1337SB.
Compare stated capacity, output, and measured exterior size
The exact MW1337SB product specification states 1.3 cubic feet and 1,000 W microwave output. It lists the outside body as 20.4 inches wide, 17.2 inches deep, and 12.3 inches high. That creates a useful measured starting point for a counter plan, but ventilation clearance, door opening, and the actual cavity measurements still matter. The source sheet is labeled preliminary and subject to change, so compare it with the manual and the specific model plate when evaluating a used or older unit. No separate electrical-input figure was established in the evidence used here, so none is substituted for the output rating.
Six presets are documented; sensor cooking is not
The exact-model sheet lists six pre-programmed recipes for popcorn, potato, pizza, frozen vegetables, beverages, and dinner plates. It also lists time and weight defrost, a digital clock/timer, child-safe lockout, and an end-of-cooking signal. Those preset controls can help someone who wants named shortcuts as well as touch-entry cooking. The reviewed MW1337SB documents do not explain a humidity sensor or describe the presets as sensor features. A menu program alone does not establish sensing, so sensorCooking remains null. The exact specification sheet lists 11 power levels, while secondary manual-page metadata lists 10; that count conflict is deliberately omitted from the comparison.
A glass turntable is present, but its diameter is open
The MW1337SB specification sheet says the oven has a removable glass turntable, and the owner's manual contents include the turntable and operating instructions. Neither exact-model document reviewed here states its diameter. The capacity and outside dimensions therefore do not answer whether a particular dinner plate or wide platter will rotate without touching the cavity. Check the installed tray and interior on the actual unit before relying on it for a dish with tight dimensions. The profile leaves turntableDiameterIn null rather than borrowing a diameter from the neighboring MW1338SB or a parts listing for a different suffix.
Treat the installation route and duty class as unconfirmed
The exact MW1337SB owner manual includes an installation section, while the specification sheet gives a compact freestanding body size. The sources reviewed do not identify an MW1337SB trim kit or give a model-specific authorization for a built-in opening, so trimKitCompatible remains null. They also do not explicitly classify this model as household-only or commercial/foodservice-duty equipment. Its commercialDuty field stays null. Follow the exact manual's clearance instructions and confirm the intended mounting and electrical conditions rather than assuming a countertop form can be enclosed in cabinetry or used for shared commercial service.
Use the exact-model search and verify the offered suffix
The historical source record uses ASIN B018BA7PP8 and the model string MWG1337SB, but the pages available for direct review did not establish an exact ASIN match. The affiliate destination searches for Emerson MW1337SB and carries buyershortlists-20; it does not link to the historical ASIN. Search results may include MW1338SB or other Emerson countertop models, so confirm the complete code and finish on the actual listing. No present stock, price, or sales volume is claimed.
What else to compare
Sharp R-431ZS is another 1.3-cu.-ft., 1,000-W countertop option with a documented 12.8-in. Carousel tray. MW1337SB's sheet instead describes a black cabinet/stainless front and touch controls with six named presets, but its tray diameter and sensor status remain unknown. GE Profile PEM31DFWW offers a smaller 1.1-cu.-ft. sensor model with optional exact-suffix trim kits. Compare the verified turntable and installation information against the actual dishes and counter opening before deciding.
Before you buy
What is the capacity and output for MW1337SB?
Its exact-code specification sheet states 1.3 cu. ft. and 1,000 W microwave output. The sheet notes that the specifications are preliminary.
What finish does the specification list?
It describes a stainless-steel front and black cabinet. Verify the full model code and finish on the specific unit.
Does MW1337SB have sensor cooking?
The sources reviewed list six pre-programmed recipes but do not document a humidity sensor, so sensor cooking remains unconfirmed.
How large is its turntable?
The exact-model specification confirms a removable glass tray but does not give its diameter.
Is MWG1337SB another name for MW1337SB?
No alias was established. The frozen record has an extra G; MW1337SB is independently documented, and the row's ASIN mapping remains unresolved.
Is MW1337SB the same as MW1338SB?
No. Emerson's product page identifies MW1338SB as a separate model code; this entry keeps the two distinct.

The decision
MW1337SB is worth comparing when 1.3 cu. ft., 1,000 W output, its black/stainless finish, and touch-control presets match the need. Its tray diameter, sensor cooking, trim-kit compatibility, and duty class are unconfirmed. The frozen source code contains an extra G and ASIN B018BA7PP8 remains unmapped; the tagged link searches the independently documented MW1337SB code and does not imply an exact listing match.
