Our take
BLACK+DECKER EM031MFO-X1 is a documented 1.1-cu.-ft. countertop microwave with 1,000-W cooking output and a 12.4-in. turntable according to its model-family manual. The same table distinguishes 1,500-W input, and its installation page gives measurable counter clearances. The interface is more than a basic timer: the manual lists weight and time defrost, ten power levels, express cooking, a two-stage program, memory and six menu categories. A retailer page for the exact X1 code gives the tray as 13 inches, so the manual's 12.4-inch value is retained while that conflict is made visible.
Consider EM031MFO-X1 for its documented 1.1-cu.-ft. cavity, 1,000-W output, weight/time defrost and six auto-menu categories. Plan a level countertop location with 3 inches at adjacent walls, one side open and 12 inches above, and keep it away from a range or heat source. The manual measures the turntable at 12.4 inches; Lowe's exact-X1 listing says 13 inches, so check the actual tray before sizing cookware or ordering a replacement. Confirm the complete X1 model code because this is not the earlier EM031MGG-X1. Sensor cooking, a trim-kit path, foodservice duty and a direct Amazon ASIN remain unverified..
Do not use this model where a 12-inch overhead opening and one open side cannot be provided, or install it over a cooktop or other heat-producing appliance. Do not assume sensor cooking or built-in trim-kit compatibility from its auto menus or countertop dimensions; the reviewed manufacturer manual does not document those features.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manual names EM031MFO-X1 and specifies 1.1 cu. ft., 1,000-W output, 1,500-W input and 120 V / 60 Hz.
- A 12.4-in. turntable is stated in the manual, and countertop placement clearances are specific and measurable.
- Time/weight defrost, +30-second express cooking, ten power levels, two-stage cooking, memory and six auto-menu categories are documented.
What to weigh up
- The required 12-in. overhead space and open side can limit where it can sit on a counter.
- Lowe's exact-X1 page lists a 13-in. turntable, conflicting with the manufacturer's 12.4-in. manual specification; verify the physical tray for cookware fit.
- The exact manual does not establish sensor cooking, a trim-kit path or commercial foodservice classification; historical ASIN B01K1JVYMM did not load.

What the features mean for you
Keep the MFO-X1 separate from the MGG-X1
The frozen record identifies model EM031MFO-X1. BLACK+DECKER's instruction manual cover explicitly lists EM031MFO-X1 and EM031MFO-X2, and Lowe's exact-model page names EM031MFO-X1 as a white countertop microwave. This supports the exact X1 code and the white finish for this row. It is not the earlier catalog entry EM031MGG-X1: the middle letters differ, and none of the reviewed sources provides an alias or interchangeability crosswalk between MFO and MGG. Keep the code on a search result or appliance label visible when comparing parts or a replacement unit. ASIN B01K1JVYMM returned an internal error, so the source row's direct retail mapping remains unverified.
The manual separates 1,000-W output from 1,500-W input
The exact model-family specification table lists 1,000 W under rated microwave output and 1,500 W under rated microwave input, at 120 V and 60 Hz. The cavity capacity is 1.1 cubic feet. These are not interchangeable numbers: the output is the stated cooking rating, while input describes electrical draw. Avoid comparing the input figure with another microwave's cooking output. The table's extracted external-dimension and weight text is incomplete, so I have not reconstructed those values from broken OCR. Use the full appliance label and installation instructions when checking the site; a wattage comparison does not promise an individual cooking time or outcome.
The control panel offers presets and manual timing
The manual lists time cook, time defrost, weight defrost, Power, a kitchen timer, number keys, memory, Stop/Cancel and Start/+30 seconds. Its auto menu names popcorn, potato, pizza, frozen vegetable, beverage and dinner plate; the guide supplies weight or serving choices for those menu buttons. It also describes a maximum of two cooking stages, with defrost first if one stage is defrosting, and three saved memory procedures. Those are useful distinctions from a microwave limited to simple timed heating. The manual does not call any menu a humidity-sensor program. Auto-menu controls alone do not establish sensor cooking, so the profile keeps that field null.
Use the stated counter clearances and check the tray size
The manufacturer's countertop-installation page asks for at least 3 inches between the oven and adjacent walls, with one side open, and 12 inches above. It says not to remove the feet, to keep ventilation openings unblocked and not to put the oven over a range or other heat-producing appliance. The manual's specifications list a 12.4-inch turntable diameter. Lowe's exact-X1 product record lists 13 inches instead. I retain the model manual's figure for the source-backed tag and disclose the difference rather than blending the two numbers. If the dish is close to the tray edge or replacement parts are being ordered, confirm the physical tray and its part number for the X1 unit.
Several installation and duty questions remain unconfirmed
The manual documents countertop placement but does not identify an optional built-in trim kit. It also does not classify EM031MFO-X1 for commercial foodservice use or describe a sensor cooking feature. Those fields remain unknown rather than being marked absent from a partial text extract. A residential retailer listing is not a manufacturer commercial-duty statement. The user should use a manufacturer-approved kit only if an exact X1 compatibility source is found, and professional-kitchen decisions should be based on an explicit duty rating and electrical installation guide. The old Amazon ASIN page did not provide a verified variant; use the tagged search and confirm the full X1 model code.
What else to compare
If verified sensor cooking or an exact-model built-in trim-kit route is essential, compare models with manufacturer documentation that names both the feature and the full code. EM031MFO-X1 is documented with multiple presets, power adjustment and countertop installation, but its manual does not establish those two options.
Before you buy
What capacity and cooking output are listed for EM031MFO-X1?
The manual lists 1.1 cu. ft. and 1,000 W rated microwave output; it separately lists 1,500 W input.
What is the manufacturer's turntable measurement?
The manual lists 12.4 inches. Lowe's exact-X1 page lists 13 inches, so check the actual tray if the measurement is critical.
Which automatic cooking categories are documented?
The manual names popcorn, potato, pizza, frozen vegetable, beverage and dinner plate, plus time/weight defrost and variable power.
Does this model have sensor cooking or an optional trim kit?
Neither feature is established by the reviewed BLACK+DECKER manual, so both remain unknown.
How much counter clearance does the manual require?
It calls for at least 3 inches from adjacent walls, one side open and 12 inches overhead; do not install over a range or heat source.
Can B01K1JVYMM be linked as the exact Amazon offer?
No. The historical ASIN page returned an internal error; use the tagged search for EM031MFO-X1.
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
BLACK+DECKER EM031MFO-X1 is a 1.1-cu.-ft. countertop microwave with 1,000-W output, 1,500-W input and a manual-listed 12.4-in. turntable. Ten power levels, six auto-menu categories, weight/time defrost, staged cooking and memory are documented. Provide the manual's 3-in. adjacent-wall, one-open-side and 12-in. overhead clearances. Lowe's exact-X1 listing gives a conflicting 13-in. tray measurement. Sensor cooking, trim-kit compatibility, commercial duty and the historical Amazon mapping remain unconfirmed; keep this MFO code separate from MGG-X1.
