Our take
The Emerson MW8998B is a black 0.9-cu.-ft. countertop microwave with 900-W output, ten power levels and eight one-touch settings. It fits basic reheating and preset use where its compact cavity is sufficient; its presets are not documented as sensor cooking.
A straightforward small-cavity choice for timed and preset household tasks when the exact MW8998B code and 120-V/60-Hz supply match the planned setup..
Choose another model if you need a confirmed sensor program, a measured turntable size, a documented trim-kit option or an exact current offer tied to the historical ASIN.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact manual names MW8998B and documents a 0.9-cu.-ft. cavity and 900-W output.
- The exact retailer listing confirms countertop format, black finish and a removable glass turntable.
- Eight one-touch settings and ten power levels provide more choices than a single timed-start control.
What to weigh up
- The evidence does not confirm that its one-touch menus use a sensor.
- No exact tray diameter, compatible trim kit or commercial-use classification was established.
- The historical Amazon ASIN is not treated as a current exact-model listing.

What the features mean for you
Check the full MW8998B suffix
The owner's manual names MW8998B, and the retailer's exact-model page identifies the same black unit. Keep the final B in the code when comparing products: similar Emerson names, capacities or output ratings alone do not establish a variant match. A tagged Amazon search is used because the historical candidate ASIN has not been mapped to a current offer. Check the model label and the included turntable in any result before deciding that a seller's package is the appliance described here.
Use the cavity rating as a screening measure
The manual gives 0.9 cu. ft., which places this among smaller countertop models. That number does not specify the largest dish that will fit, and no exact tray diameter was found in the reviewed sources. Measure the space available on the counter and check the interior tray with the plates and bowls you use most. If you regularly heat broad serving dishes, compare a larger model with a confirmed turntable dimension. This Emerson's appeal is a compact form and simple controls, not a documented large-cookware advantage.
Treat one-touch menus as presets, not proven sensors
The retailer lists eight one-touch settings and ten power levels, while the owner's manual provides cooking, defrost and auto-cook instructions. Those controls can save key presses for common tasks and still let users choose a power level or cooking time. The materials reviewed do not label the MW8998B as a sensor-cooking model. Leave that feature unconfirmed rather than interpreting a preset button as a humidity or temperature sensor. If sensor reheat is essential, compare an exact model whose manual explicitly names sensor cooking.
Use the separate output and supply numbers correctly
The MW8998B manual identifies 900 W of microwave output and 120 V / 60 Hz supply. Output is the cooking rating, not the amount of power drawn from the wall; this review does not substitute it for an input specification. Before plugging in a used or renewed unit, check its rating plate, grounding instructions, circuit and clearance needs. The supplied evidence supports the voltage and frequency match for the standard U.S. finder path, but does not answer every electrical-installation question.
Choose countertop placement unless exact fit evidence appears
Newegg classifies the exact MW8998B as a countertop microwave and identifies its removable glass turntable and child lock. No exact trim-kit code is documented, so leave cabinet conversion out of the plan unless Emerson provides a model-specific installation route. A removable tray can be taken out for cleaning, but the sources do not support a claim about cleaning effort or long-term durability. Commercial-duty status also remains unknown; the available documents describe a household-style consumer model without establishing foodservice use.
What else to compare
Before you buy
Does the MW8998B have sensor cooking?
The checked sources do not confirm sensor cooking; one-touch settings alone are not evidence of a sensor.
What supply does the owner's manual list?
The MW8998B manual lists a 120-V, 60-Hz supply; check the rating plate and circuit for the unit in hand.
Is its turntable removable?
The exact-model retailer listing identifies a removable glass turntable, but does not give its diameter.
Can it be installed in a trim kit?
No exact MW8998B trim-kit route was established in the sources reviewed for this profile.
