Our take
GE's exact JES1657SMSS page documents a 1.6-cu.-ft. countertop microwave with 1,150-W output, sensor controls, a 13.625-in. turntable and a 120-V electrical rating. GE states that the model is no longer manufactured. The GE-linked family manual describes humidity sensing but warns that features vary by model. The exact page and manual checked for this record do not establish 60 Hz, so the model cannot be treated as compatible with the standard 120-V / 60-Hz answer path without checking the unit's rating plate. This review uses published model material, not testing or buyer-review claims.
Consider JES1657SMSS only after its own rating plate and manual confirm the electrical frequency for your installation. GE documents 120 V, but the sources checked here do not establish 60 Hz. Measure the 21.75 x 17.75 x 12.875-in. body and door clearance; the historical ASIN did not verify a current exact offer..
Do not choose this model for a verified 120-V / 60-Hz installation until the exact unit documentation confirms frequency. It is also a poor fit if you require current manufacturer production, verified finish, trim-kit evidence or an exact current Amazon page.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- GE's exact product page lists 1.6 cu. ft. and 1,150 W of microwave output, separating output from the 1,600-W input rating.
- The page documents sensor controls and a 13.625-in. turntable, giving concrete cooking-control and dish-fit comparison points.
- GE publishes body dimensions that help check the counter footprint before seeking a verified offer.
What to weigh up
- The checked exact-model sources say 120 V but do not establish 60 Hz, leaving standard U.S. supply compatibility unknown.
- GE marks the model no longer manufactured; that does not establish whether any particular listing is available or new.
- The exact finish, trim-kit compatibility and commercial-duty classification are not established in the reviewed materials.
The key details
| Model covered | JES1657SMSS |
|---|---|
| Capacity | GE lists 1.6 cu. ft. capacity and 1,150 W of IEC-705 microwave output for JES1657SMSS. |
| Microwave output | The exact product page gives 120 V and 1,600 W electrical input; the reviewed exact-model sources did not establish 60 Hz. |
| Cooking approach | GE lists sensor-cooking controls; the linked JES1657 family manual describes humidity sensing and cautions that features vary by model. |
| Installation options | The exact product page lists a 13.625-in. turntable and exterior dimensions of 12.875 H x 21.75 W x 17.75 D in. |
| Finish and turntable | GE says this model is no longer manufactured; finish, commercial classification and trim-kit compatibility remain unconfirmed. |

What the features mean for you
A medium-large cavity with a measurable tray
GE gives JES1657SMSS a 1.6-cu.-ft. cavity and a 13.625-in. turntable. These figures distinguish it from compact .7- and .9-cu.-ft. models, but a turntable diameter is not the same as a rectangular dish's usable width. Measure the base of cookware and verify that it can rotate inside the actual cavity. GE lists a 21.75-in. width, 17.75-in. depth and 12.875-in. height, which can be compared with the available counter and surrounding ventilation space. A published exterior dimension does not replace checking the open door and the installation guide.
Read output and electrical input as different numbers
GE lists 1,150 W as microwave output and 1,600 W as electrical input. The output figure is what the finder uses for an output preference; it does not predict cooking time or mean that the appliance draws 1,150 W from the outlet. The product page confirms 120 V, but the exact-model materials checked here did not show 60 Hz. That matters because every current answer case requiring standard U.S. supply filters on both voltage and frequency. Confirm the nameplate and model-specific manual before treating this microwave as compatible.
Sensor controls are documented with a family suffix caveat
GE's exact page lists sensor-cooking controls, and the linked JES1657 family manual describes humidity-sensor operation. The same manual warns that features and appearance can vary among related models. The exact product page therefore supports sensorCooking=true for this code, while the family warning prevents carrying every family feature into this suffix. Sensor automation is an available program, not a guarantee about every portion or cookware choice. Follow the exact unit's user instructions and use manual time and power when a food or serving size is not covered by a sensor program.
Treat discontinuation and electrical uncertainty separately
GE says JES1657SMSS is no longer manufactured. This is a manufacturer status statement, not a claim that a listing is currently in stock, unavailable everywhere, or a particular price. Separately, 60-Hz supply support remains unknown because the exact-model material checked here gives 120 V but not frequency. Do not let the model's U.S. brand or an apparently familiar plug resolve that missing fact. Compare the exact nameplate and manual, and verify circuit and grounding requirements for the particular unit before purchase or use.
Do not assume a finish or built-in conversion
The frozen listing string includes a suffix that may look like a finish code, but the reviewed GE materials do not confirm a finish for this exact model. The sources also do not establish a compatible trim kit. Both values remain unknown rather than being inferred from the stainless wording in the historical title or another GE model. Plan on a countertop microwave only unless GE's exact installation documents show otherwise. If a seller description supplies variant or built-in claims, check that it names JES1657SMSS itself and the correct accessory.
Use a tagged model search, not an old ASIN
The historical Amazon page returned an internal error during the saved check, so it did not prove that its ASIN still maps to the exact model. The shopping link searches GE JES1657SMSS with the affiliate tag and avoids presenting that old mapping as current proof. Confirm the full model code, condition, rating plate and accessories in any result. No exact current offer, price or inventory is asserted. If verified 60-Hz support is a must-have, compare with another product whose exact manual documents the complete 120-V / 60-Hz supply.
What else to compare
For a documented U.S. 120-V / 60-Hz sensor model, Panasonic NN-SN736W lists a 1.6-cu.-ft. cavity and 1,250-W output, while Panasonic NN-SN946B offers 2.2 cu. ft. Verify their separate trim and finish boundaries. JES1657SMSS remains a potential choice only after its exact frequency is confirmed.
Before you buy
What are the capacity and output?
GE lists a 1.6-cu.-ft. cavity and 1,150 W of microwave output for exact model JES1657SMSS.
Does GE document sensor cooking?
Yes. The exact product page lists sensor controls; the linked family manual warns that features vary by model.
Is it confirmed for 120 V / 60 Hz?
The checked exact-model source gives 120 V but did not establish 60 Hz, so verify the unit rating plate.
Is JES1657SMSS still manufactured?
GE says the model is no longer manufactured; this does not establish current stock for any seller.
Can I use the old Amazon ASIN directly?
The historical page did not verify an exact current offer, so the tagged exact-model search is used instead.
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
JES1657SMSS has useful published capacity, output, sensor and turntable specifications, but the exact frequency is unresolved and GE says production has ended. It stays out of standard-supply cases until 60 Hz is confirmed. Finish, trim kit, commercial duty and current Amazon identity remain unverified; use the tagged model search.
