Our take
Panasonic NN-SN661S is a household-use 1.2-cu.-ft. countertop microwave with 1,200-W IEC cooking output. Its manual separates that from 1,480-W/12.4-A electrical consumption and specifies 120 V/60 Hz. Panasonic documents Sensor Reheat and Sensor Cook and lists NN-TK621SSAP for NN-SN661S/SN671S. The tray diameter is not stated, and the source does not corroborate the frozen row's NN-SN661SAZ suffix or historic ASIN. This review describes the documented base model and keeps those identity limits visible; it is not a personal cooking test.
Consider NN-SN661S when a household 1.2-cu.-ft. sensor microwave and documented kit route suit the kitchen. Measure the cabinet opening and verify the exact kit and suffix before installation. The 1,480-W/12.4-A input matters for circuit planning; output is a separate rating..
Choose another model for commercial kitchens, a must-have tray diameter, or a purchase where NN-SN661SAZ or the old ASIN must be proven as an exact maker-approved offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Panasonic documents Sensor Cook and Sensor Reheat for the exact base model.
- The manual distinguishes 1,200-W IEC output from 1,480-W/12.4-A input on a 120-V/60-Hz supply.
- A model-specific NN-TK621SSAP trim kit and cabinet opening are listed by Panasonic.
What to weigh up
- Turntable diameter and finish are not stated in the reviewed exact-model material.
- The added AZ suffix and historical B0041BKWBQ ASIN do not have an exact manufacturer crosswalk.
- The manual says household use only and not approved or tested for commercial use.
The key details
| Model covered | NN-SN661S |
|---|---|
| Capacity | Panasonic lists a 1.2-cu.-ft. cavity for the NN-SN661S family. |
| Microwave output | The manual specifies 1,200-W IEC microwave output, separate from 1,480-W / 12.4-A electrical input. |
| Cooking approach | Sensor Cook and Sensor Reheat are documented; the model is identified for household use only. |
| Installation options | Panasonic lists trim kit NN-TK621SSAP and a cabinet opening of 25.5 W × 15.3125 H × 21 D in.; confirm the exact suffix and kit instructions. |
| Finish and turntable | The supported base code is NN-SN661S. Finish and turntable diameter remain unknown; NN-SN661SAZ and the old ASIN lack an exact crosswalk. |

What the features mean for you
Use the corroborated base code
The frozen title says NN-SN661S, while its structured field adds AZ. Panasonic's manual and trim-kit finder identify NN-SN661S, and the saved research found no maker crosswalk for NN-SN661SAZ. Keep the catalog on the supported base code and do not infer a finish or separate variant from the extra letters. This matters when comparing replacement parts, installation kits and seller offers: a similar string is not proof of maker identity.
Sensor programs provide a documented control option
Panasonic supplies Sensor Cook and Sensor Reheat procedures for the NN-SN661 family. That gives shoppers a clear distinction from models whose documentation lists only timed cycles or preset keys. The feature applies to selected foods and instructions, not every container or portion, and the manual does not promise identical results for all uses. A buyer who values sensor programs can use this evidence; someone who prefers direct timing can still compare the standard cooking controls.
Separate cooking output from electrical demand
The specifications list 1,200 W IEC cooking output and separately state 1,480 W / 12.4 A input at 120 V/60 Hz. Output is the published microwave rating; input and amperage are the numbers to consider for electrical planning. Mixing them can misstate both cooking output and draw. Panasonic also says this is household-use equipment, not approved or tested for commercial use, so high output does not make it a foodservice model.
Follow the exact trim-kit information
Panasonic lists NN-TK621SSAP for NN-SN661S/SN671S and provides a cabinet opening of 25.5 W × 15.3125 H × 21 D inches. This is a model-specific installation route, not proof that the microwave is a built-in appliance by itself. Verify the full unit code, kit compatibility, ventilation and opening dimensions before ordering. The reviewed sources do not state the turntable diameter, so the trim data cannot settle dish fit.
Use the exact-model search for shopping
The historical B0041BKWBQ page returned an internal error, and the saved evidence does not map it to a current exact offer. The tagged Amazon search uses the documented NN-SN661S base code instead of the unsupported AZ suffix. Confirm the model label and kit pairing on a listing before buying. The search is a way to inspect offers, not evidence of present price, stock or seller condition.
What else to compare
Before you buy
What is the microwave output?
Panasonic lists 1,200 W IEC output and separately lists 1,480 W / 12.4 A electrical input.
Does NN-SN661S have sensor cooking?
Yes. Panasonic documents both Sensor Cook and Sensor Reheat for the model family.
Which trim kit is listed?
Panasonic names NN-TK621SSAP for NN-SN661S and NN-SN671S; verify the exact unit suffix.
Is this a commercial microwave?
No. Panasonic's manual says household use only and not approved or tested for commercial use.
Does the old Amazon page prove the AZ suffix?
No. B0041BKWBQ failed recheck, so the tagged exact-base-model search is used.
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.
