Our take
Frigidaire's FFCE1439L family sheet supports the row's black FFCE1439LB identity: it maps suffix B to black and describes the W/B models as countertop microwaves. It lists 1.4 cu. ft., 1,100 W IEC output, ten power levels, multi-stage cooking and Sensor One-Touch features. The same document separates 1,550 W/13 A electrical input from cooking output and calls for a 120-V/60-Hz/15-A supply. One practical fit detail is unresolved: the sheet says the turntable is 14 3/16 inches, while Lowe's listing for exact model FFCE1439LB says 12.4 inches. I leave tray diameter unknown rather than choose one. The maker lists 3-inch side/rear and 12-inch top clearances; it does not establish an exact trim kit or commercial classification. Amazon B005VV5XYG failed to load, so this review uses a tagged exact-model search and does not claim that ASIN.
The FFCE1439LB fits a comparison for a black countertop form factor, a 1.4-cu.-ft. stated cavity and sensor cooking options. Frigidaire maps the B suffix to black in the FFCE1439L W/B family. Its sheet lists 1,100 W microwave output separately from 1,550 W/13 A electrical input and specifies a 120-V/60-Hz/15-A supply. Check the available footprint against 21 3/4 × 12 7/8 × 18 1/2-inch exterior dimensions, leaving the listed 3 inches at each side and rear and 12 inches above. Confirm tray size before relying on a large round dish: the family specification says 14 3/16 inches, but a Lowe's page for exact model FFCE1439LB says 12.4 inches. I have not resolved that conflict, so the matching tag remains null. The specification does not establish an exact trim kit or commercial-duty status. Amazon B005VV5XYG failed to load; the tagged affiliate destination searches FFCE1439LB and makes no direct-ASIN claim..
Do not rely on this entry if a precise tray diameter is essential until you can verify the appliance documentation or measure the unit. Do not plan a built-in opening from the countertop description alone: an exact compatible trim kit is not established. Check the stated 15-A supply and generous top clearance against the installation location.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Frigidaire lists a 1.4-cu.-ft. cavity and 1,100 W cooking output, with electrical input separately identified.
- The family sheet documents Sensor One-Touch options, ten power levels and multi-stage cooking.
- Suffix B is explicitly mapped to black, and the spec provides cabinet dimensions and required clearances.
What to weigh up
- Turntable diameter is contradictory: 14 3/16 inches in the family sheet versus 12.4 inches on an exact-model retail listing.
- The documentation reviewed does not confirm a compatible built-in trim kit or classify the oven for commercial foodservice duty.
- The historical Amazon ASIN could not be verified against the exact model.
The key details
| Model covered | FFCE1439LB |
|---|---|
| Capacity | Frigidaire lists 1.4 cu. ft. for FFCE1439L W/B; Lowe's exact-model page identifies FFCE1439LB as the black variant. |
| Microwave output | Frigidaire lists 1,100 W IEC microwave output separately from 1,550 W/13 A input and a 120-V/60-Hz/15-A supply. |
| Cooking approach | Sensor One-Touch, sensor reheat/vegetable options, ten power levels and multi-stage cooking are documented for this family. |
| Installation options | Countertop dimensions are 21 3/4 × 12 7/8 × 18 1/2 inches, with 3-inch side/rear and 12-inch top clearances; exact trim-kit compatibility is unconfirmed. |
| Finish and turntable | The B suffix means black; turntable diameter remains unknown because the family sheet says 14 3/16 inches and Lowe's exact-model page says 12.4 inches. |

What the features mean for you
The B suffix supports the black variant
Frigidaire's family specification names FFCE1439L W/B and maps B to black and W to white. Lowe's identifies the exact FFCE1439LB model as black and countertop. That supports the frozen row's model and finish pairing. The family mapping does not make every FFCE-series microwave interchangeable, so keep the complete FFCE1439LB model code attached to this record.
Read the output and electrical input separately
The family sheet lists 1,100 W IEC microwave output, then separately lists 1,550 W and 13 A input. It specifies a 120-V, 60-Hz supply with a 15-A circuit. These figures describe different things: use the electrical requirement to check the outlet and circuit, and do not substitute 1,100 W cooking output for the unit's input draw.
Sensor options are documented for this family
Frigidaire lists Sensor One-Touch features and sensor-based reheat and vegetable options, along with ten power levels and multi-stage cooking. Those named controls support a sensor-cooking tag. They do not establish a cooking result for every food or container, so follow the appliance's own operating instructions for cycle selection and cookware guidance.
The published turntable sizes disagree
The Frigidaire/Electrolux family sheet gives a 14 3/16-inch turntable diameter. Lowe's page for exact model FFCE1439LB reports 12.4 inches. Because those measurements differ, the structured diameter tag is left null. If a particular plate must rotate without touching the oven walls, verify the actual turntable or current model documentation before buying.
Counter placement needs the listed clearance
The family sheet gives exterior dimensions of 21 3/4 × 12 7/8 × 18 1/2 inches and calls for 3 inches at the sides and rear and 12 inches above. Include that open space when checking a counter or shelf. The materials reviewed do not establish an exact compatible trim kit, and a countertop designation by itself is not evidence of built-in approval.
The source set does not settle commercial-duty status
The manufacturer sheet identifies a countertop model, sensor controls and a U.S. 120-V/60-Hz supply but does not expressly classify FFCE1439LB as either foodservice equipment or household-only. I leave that matching tag unknown rather than infer duty class from the Frigidaire brand, power rating or retail category.
What else to compare
For a model with an unconflicted manufacturer-listed turntable measurement, compare Sharp R-308JK: Sharp lists a 12 5/8-inch tray, 1.0 cu. ft. and 1,100 W output, but no sensor cooking. The Frigidaire family lists a larger 1.4-cu.-ft. cavity and sensor options, while its tray diameter remains disputed. Compare the dish fit, features and clearance needs using the actual manuals before choosing.
Before you buy
What is the capacity and cooking output?
Frigidaire lists 1.4 cu. ft. and 1,100 W IEC microwave output for the FFCE1439L family.
Is FFCE1439LB black?
Yes. The family specification maps suffix B to black, and Lowe's identifies the exact FFCE1439LB model as black.
What electrical supply does the sheet specify?
It lists 120 V, 60 Hz and a 15-A circuit, with 1,550 W/13 A electrical input separate from 1,100 W microwave output.
Does it have sensor cooking?
The family sheet lists Sensor One-Touch and sensor reheat/vegetable options.
How wide is the turntable?
The family sheet says 14 3/16 inches, while Lowe's exact-model listing says 12.4 inches. The diameter remains unconfirmed.
Can it be installed in a cabinet with a trim kit?
No exact FFCE1439LB trim-kit compatibility was established by the reviewed manufacturer documentation.
Does it have a commercial-duty classification?
The reviewed manufacturer sheet does not settle its commercial-duty classification, so that tag remains unknown.
Does Amazon ASIN B005VV5XYG identify FFCE1439LB?
The Amazon route returned an internal error. This entry uses a tagged exact-model search and does not claim a direct ASIN match.

The decision
Frigidaire FFCE1439LB is supported as the black FFCE1439L countertop variant, with 1.4 cu. ft., 1,100 W output and documented sensor options. The sheet specifies a 120-V/15-A supply and 3-inch side/rear plus 12-inch top clearances. Do not rely on a precise turntable diameter until the 14 3/16-inch manufacturer figure and 12.4-inch exact-model listing are reconciled. The materials reviewed establish neither an exact trim kit nor a commercial-duty classification, and Amazon B005VV5XYG remains unverified; use the tagged exact-model search.
