Our take
GE JE740DRBB is a black 0.7-cu.-ft. countertop microwave with 700-W output, ten power levels, a 9.625-in. glass turntable, 120-V input and an optional separate under-cabinet hanging kit. Sensor cooking and a built-in trim-kit route are not established; GE lists the model as no longer manufactured.
A compact black microwave for a narrow counter location where a small cavity and 700-W output meet the task. Its optional hanging kit is a separate under-cabinet accessory, not permission to treat the oven as a built-in trim-kit model. Check cookware against the 9.625-in. glass tray..
Choose a larger-output or larger-cavity model if wide dishes, a high wattage threshold, sensor cooking or a documented built-in trim-kit installation matters.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- GE's exact product record identifies the black JE740DRBB and its 120-V electrical input.
- The 0.7-cu.-ft. cavity, 700-W output and 9.625-in. tray are model-specific measurements.
- An optional hanging kit is documented as an under-cabinet route to free counter space.
What to weigh up
- The 700-W output and 9.625-in. turntable constrain comparisons with larger, higher-output models.
- Sensor cooking and built-in trim-kit compatibility are not confirmed.
- GE dates manufacture to 2011–2014 and identifies the model as no longer manufactured; historical Amazon ASIN B004VFXAWU failed.

What the features mean for you
Consider the compact cavity for small cookware
GE identifies JE740DRBB as a 0.7-cu.-ft. countertop microwave. Its smaller cavity may suit a mug, small plate or limited counter footprint, but capacity does not by itself prove that your bowl will rotate. GE's exact product record lists a 9.625-in. glass turntable, so compare the dish base against that tray and leave room for rotation. Larger cookware or wide family dishes may call for a bigger cavity and turntable. The product page lists compact exterior dimensions of 9 7/8 by 17 5/16 by 12 3/4 inches; still check the manual's ventilation clearance and the actual counter space.
Use 700 W as a stated output, not a speed promise
The GE record states 700 W of microwave output and ten power levels. It also lists 120-V input and 1,150 W of electrical input, which is not the same as cooking output. The lower output is a real comparison tradeoff if you routinely choose high-output models, but it does not support a measured claim about how long a particular meal will take. Use the manual's food instructions and check the unit rating plate and circuit requirements. If a questionnaire answer requires at least 1,000 W, the profile correctly excludes this model; if output is only a preference, it may remain a compact alternative.
Separate the hanging kit from a trim-kit installation
GE lists optional hanging kit JXA019K, described as an under-cabinet installation that frees counter space. That accessory is not the same as a built-in trim kit that fills a cabinet opening around an oven. The reviewed GE documents do not establish a trim-kit route for JE740DRBB, so that attribute remains unknown rather than being set to compatible. Follow the hanging kit's model-specific instructions if that mounting method is considered, and do not infer compatibility with custom cabinetry from the product's compact size. For ordinary use, the product is documented for countertop placement.
Do not infer sensor cooking from one-touch controls
GE lists convenience cooking controls, one-touch operation, auto and time defrost, instant-on controls and a kitchen timer. These features make the operation style different from a model whose maker explicitly documents sensor cook. The reviewed JE740DRBB sources do not establish sensor cooking, so sensorCooking remains null and the model cannot satisfy a hard sensor requirement. The GE specification sheet lists ten power levels and a rotating tray, which are useful documented facts, but neither indicates that a humidity sensor is included. Select this model only when its known small-space and output profile aligns with the routine.
Check the lifecycle and exact listing identity
GE's exact product record dates manufacture from March 2011 through October 2014 and states that the model is no longer manufactured. That is lifecycle information from the manufacturer, not a statement about current new or used inventory. The historical Amazon ASIN B004VFXAWU returned an internal error, so the link searches JE740DRBB and carries the required tracking tag. Check the exact black suffix and the condition, accessories and supply label on any result. No current price, offer, stock count, sales rank or buyer-review summary is included.
What else to compare
Before you buy
What is the output and cavity size?
GE lists 700 W of microwave output and a 0.7-cu.-ft. cavity for JE740DRBB.
How wide is the turntable?
GE's exact product record lists a 9.625-in. glass turntable; check the dish base and rotation clearance.
Does the model use a standard U.S. outlet?
GE lists 120-V electrical input. Check the exact rating plate, circuit and grounding instructions before use.
Is the hanging kit a trim kit?
No. JXA019K is an optional under-cabinet hanging kit; the reviewed sources do not establish built-in trim-kit compatibility.
Does GE document sensor cooking?
The reviewed exact-model materials list convenience controls but do not confirm sensor cooking.
Is JE740DRBB still manufactured?
GE's product record dates manufacture to 2011–2014 and says the model is no longer manufactured; this does not establish today's inventory.
