Our take
GE's JES1142SJ page describes a stainless 1.1-cu.-ft. countertop microwave with 1,100-W output, a 12.8-in. glass turntable, convenience controls, defrost and ten power levels. GE lists 120-V electrical input at 1,500 W / 13 A, but the reviewed exact sources do not state frequency. GE says the model is no longer manufactured, which does not establish seller inventory. Sensor cooking and trim compatibility are not confirmed. The historical ASIN failed, so the affiliate link searches the exact model.
Choose GE JES1142SJ for stainless finish, 1,100-W output and a measured 12.8-in. tray in a 1.1-cu.-ft. cavity. Samsung MS11K3000AS offers confirmed 120-V/60-Hz supply and sensor cooking; GE's reviewed source does not state frequency and says the model is no longer manufactured, so check its nameplate and any seller offer..
Choose another model if you need confirmed sensor cooking, a built-in trim-kit path, a larger cavity, or a currently supported production model. Check seller condition and remaining stock directly.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact GE page lists 1.1 cu. ft., 1,100-W microwave output and a 12.8-in. glass turntable.
- GE publishes 120-V/60-Hz supply and separates 1,500-W / 13-A input from microwave output.
- Stainless finish, countertop placement, ten levels and convenience/defrost controls are documented.
What to weigh up
- GE identifies JES1142SJ as no longer manufactured; current inventory is not established.
- Sensor cooking and compatible trim-kit installation are not listed for the exact model.
- The historical Amazon ASIN did not verify an exact offer.

What the features mean for you
A 1.1-cu.-ft. cavity with a measurable tray
GE lists 1.1 cubic feet and a 12.8-inch glass turntable for JES1142SJ. It also gives outside dimensions of 21¼ inches wide, 11⅞ inches high and 15¾ inches deep. Use the tray diameter to compare round cookware, and use the cavity measurements and actual dish shape to check clearance. Capacity is a broad volume label rather than a promise that a platter will rotate. This model is smaller by nominal capacity than the 1.5- and 1.6-cu.-ft. sensor/convection options in the batch, while its 12.8-inch tray remains a concrete fit point.
Check output and input as separate ratings
GE specifies 1,100 watts of microwave output and lists 1,500 watts / 13 amps of electrical input at 120 volts. Output is the relevant cooking rating for the finder's power comparison; input and current belong in the outlet and circuit check. Do not substitute one number for the other. The reviewed exact sources do not state the frequency, so the profile does not claim a complete 120-V/60-Hz match. Check the exact nameplate and manual, plus grounding and circuit requirements. The 1,100-W output meets the stated threshold without implying a measured cooking result.
Convenience buttons are not the same as sensor cooking
GE lists convenience cooking controls, auto and time defrost, instant-on controls, ten power levels and electronic touch pads. Those features support timed and preset use. The reviewed exact-model page and specification sheet do not name sensor cooking, so the profile leaves that field unknown rather than counting a preset as humidity sensing. If sensor cooking is a firm requirement, compare another exact model with an explicit sensor feature. If simple timed reheating and defrost are enough, the JES1142SJ's documented controls provide a clear, less elaborate workflow.
The stainless variant is documented for countertop use
GE lists a stainless-steel exterior and black/stainless door, along with countertop placement. The specified 21¼-inch width, 15¾-inch depth and 11⅞-inch height can be compared with the counter space available. GE's exact sources do not identify a compatible trim kit, so do not assume the model can be enclosed in cabinetry. The product is a household countertop microwave; the reviewed materials do not classify it for commercial food service. Keep both the variant and installation method tied to the JES1142SJ code rather than borrowing details from another GE model.
No longer manufactured does not mean unavailable
GE's support page dates manufacture from August 2004 through October 2011, and the product page says this model is no longer being manufactured. That is useful lifecycle context, but it does not state whether any seller currently has a remaining unit or what condition it is in. Confirm the exact model, accessory set and condition on the actual offer. The historical B0012ON1IG page returned an internal error, so this guide does not connect that ASIN to JES1142SJ. Use the tagged exact-model search and treat current seller details as something to verify.
Use the model code when comparing alternatives
JES1142SJ is the exact code supported by GE's product and support pages. Nearby GE models may share capacity, output, or control language while differing in turntable size and other details. Keep the exact suffix intact and compare a listing with GE's stainless description, 12.8-inch tray, 1,100-W output and electrical requirements. No direct Amazon ASIN, current price, stock amount, sales rank, buyer-review summary or hands-on result is established here. The search destination is tagged for affiliate tracking and is labeled as an exact-model search.
What else to compare
For sensor cooking or an exact trim-kit route, compare models whose manufacturer source names those features. For current production status, check the exact offer and support page before deciding.
