Our take
Panasonic NN-SN667B is a black 1.2-cu.-ft. countertop microwave with 1,300-W output, a 13.5-in. turntable, Inverter Technology, Genius Sensor Cook/Reheat and ten power levels. Its operating manual says 120 V/60 Hz, while the family specification sheet prints 115 V/60 Hz; verify the actual rating plate.
A black, medium-cavity option for users who want a 13.5-in. turntable, inverter technology and sensor-guided programs. Confirm the rating plate and circuit because the product sheet and exact manual show different nominal voltage labels; do not plan a trim-kit installation from family resemblance..
Do not choose it for a hard electrical match without checking the exact unit plate, or for cabinet installation unless Panasonic confirms a kit for the NN-SN667B suffix.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Panasonic distinguishes black NN-SN667B from the white NN-SN667W and documents a 1.2-cu.-ft. cavity.
- The 1,300-W output, 13.5-in. tray, inverter and Genius sensor functions are all listed.
- The exact B operating manual provides operating and electrical-supply guidance.
What to weigh up
- The family sheet says 115 V/60 Hz while the exact B manual says 120 V/60 Hz, so confirm the appliance plate.
- The reviewed sources do not establish a compatible trim kit or exact commercial-duty classification.
- The historical ASIN B000ON4M52 returned an internal error and is not used as a direct link.
The key details
| Model covered | NN-SN667B |
|---|---|
| Capacity | The Panasonic sheet identifies black NN-SN667B separately from white NN-SN667W |
| Microwave output | Capacity is 1.2 cu. ft.; the removable turntable is 13.5 in. |
| Cooking approach | Microwave output is 1,300 W; the spec sheet separately lists 1,460 W electrical input |
| Installation options | Inverter Technology, Genius Sensor Cook/Reheat, ten power levels and five-stage cooking are documented |
| Finish and turntable | The exact B manual states 120 V / 60 Hz; the separate specification sheet prints 115 V / 60 Hz, so verify the unit plate |

What the features mean for you
Choose the black B variant explicitly
Panasonic's NN-SN667W/B specification sheet lists the black NN-SN667B and white NN-SN667W as separate variants. Use the exact B suffix in the product search, and do not assume a white listing, image or seller bundle is the same unit. The exact B operating manual names NN-SN667B, providing a second identity reference. The catalog retains B as its own product ID and uses the historical Amazon page only as a research clue because it returned an internal error. Confirm both the full code and black finish on any result before comparing price or accessories.
Compare its medium cavity and turntable
The specification sheet lists a 1.2-cu.-ft. cavity and a removable 13.5-in. turntable. That gives a concrete comparison with 1.4-cu.-ft. models such as GE JE1460BFBB and Amana AMC5143AAW; the Panasonic's tray is wider than the 12 5/8-in. GE tray, but the larger cavity on those models may still change dish fit. Measure cookware rather than inferring it from capacity. The sheet's exterior dimensions are 20 3/8 by 15 15/16 by 11 7/8 inches. Leave the ventilation clearance required by the exact manual and check that the tray can rotate freely with your regular dishes.
Separate cooking output from electrical input
Panasonic lists 1,300 W of microwave output and separately gives 1,460 W electrical input with 12.7 A in the specification sheet. Keep those numbers in their distinct fields: the output is a cooking specification, while input and current matter for supply planning. A higher output number does not establish a measured cooking-time advantage or personal performance. The exact NN-SN667B manual states 120 V/60 Hz; the family specification sheet prints 115 V/60 Hz. Because those labels differ, check the rating plate and circuit for the unit in hand rather than relying on a generic family assumption.
Use inverter and sensor functions as documented controls
The specification sheet describes Inverter Technology, Genius Sensor Cook and Sensor Reheat, ten power levels, up to five-stage cooking, Keep Warm and Turbo Defrost. These are distinct functions: the sensor programs automate certain cooking or reheating routines, while the staged sequence can combine programmed steps and defrost. They make the control set more capable on paper than a basic one-touch-only model, but the documents do not establish that every meal needs the same setting or that results are uniform. Follow the NN-SN667B manual's instructions for preparation and safe containers; this review makes no hands-on or measured-performance claim.
Keep trim-kit and duty classifications unknown
The exact operating manual describes countertop use and supplies general safe-use instructions. The reviewed evidence does not identify a trim-kit code specifically for NN-SN667B or classify it for commercial foodservice. A conditional statement about fitting a proper kit does not itself prove that a kit exists for this suffix. Leave trimKitCompatible and commercialDuty unknown until Panasonic names an exact matching accessory or duty rating. If the microwave will sit in a cabinet opening, use only instructions that list NN-SN667B and match the cabinet dimensions; do not borrow a route from a similarly named Panasonic model.
Search the complete model code
Amazon ASIN B000ON4M52 returned an internal error during the saved candidate check. The tagged destination therefore searches Panasonic NN-SN667B, rather than asserting the old ASIN is current or exact. Confirm the B suffix, black finish, included turntable and operating label in any result. The family sheet and exact manual are the evidence base; no current price, offer availability, sales ranking or buyer-review summary is included. If supply is important, inspect the rating plate because the family spec sheet and the exact B manual use 115-V and 120-V labels respectively.
What else to compare
Before you buy
What are the cavity and tray sizes?
Panasonic lists a 1.2-cu.-ft. cavity and a removable 13.5-in. turntable for the NN-SN667W/B family.
What is the microwave output?
The specification sheet lists 1,300 W output and separately shows 1,460 W electrical input.
Does NN-SN667B have sensor cooking?
The sheet documents Genius Sensor Cook and Sensor Reheat, along with inverter technology and ten power levels.
What supply should I use?
The exact B manual says 120 V/60 Hz, while the family sheet says 115 V/60 Hz. Confirm the rating plate and circuit.
Can it use a trim kit?
The reviewed exact sources do not identify a kit for NN-SN667B; obtain suffix-specific compatibility before cabinet installation.
Is ASIN B000ON4M52 a verified current offer?
No. Its historical Amazon page returned an internal error, so the link searches the full NN-SN667B model code.
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.
