Our take
Panasonic NN-SN966SR is a stainless 2.2-cu.-ft. countertop inverter microwave with 1,250-W output and 14 Genius Sensor cook settings. Panasonic lists its footprint, but exact SR trim compatibility, input rating, tray diameter, commercial class and a current Amazon offer remain unverified.
Consider NN-SN966SR if you need a roomy 2.2-cu.-ft. countertop microwave and value documented sensor menus, inverter operation and 1,250-W output. Measure its stated width, height and depth against your counter, and treat built-in installation as unconfirmed until Panasonic documents a trim kit for the exact SR code. Confirm the nameplate and turntable size for your installation and cookware..
If you need a confirmed trim-kit installation, choose an exact model with Panasonic documentation naming its compatible kit. If you want a verified electrical input rating or numeric tray size, compare models whose exact manual supplies those specifications.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Panasonic's exact SR page identifies a 2.2-cu.-ft. stainless countertop microwave with 1,250-W output and inverter technology.
- The page lists 14 Genius Sensor cook settings, sensor reheat, turbo defrost and Keep Warm.
- Exact-model outside dimensions are provided, helping with counter planning.
What to weigh up
- Voltage, frequency and electrical input were not established for the exact SR suffix; do not borrow NN-SN966S ratings.
- The reviewed trim finder names NN-SN966S rather than NN-SN966SR, and the exact SR tray diameter is not stated.
- The historical Amazon ASIN returned an error, so no current exact offer is verified.

What the features mean for you
Keep NN-SN966SR distinct from NN-SN966S
Panasonic's current product page names NN-SN966SR, while the older manual and trim listing identify NN-SN966S. The suffix difference is not resolved by the generic historical phrase built-in. Preserve the exact SR identity, use its current page for the 2.2-cu.-ft. and countertop facts, and do not borrow electrical, tray or trim details from the base S code without a manufacturer crosswalk.
Plan for the stated full-size footprint
The exact-model page gives dimensions of 23 7/8 inches wide, 14 inches high and 19 7/16 inches deep. Measure the counter and leave the clearances required by the instructions for the actual unit. Although the frozen title calls it countertop/built-in, the reviewed exact SR page documents countertop placement; this evidence does not establish cabinet installation or a compatible trim kit.
Use sensor features as a documented distinction
Panasonic lists 14 Genius Sensor cooking settings and sensor reheat for NN-SN966SR. Those named functions can matter if you want preset programs that respond to food rather than setting every cook time manually. They do not tell you that every food or container will suit a sensor cycle, so follow the matching manual and choose programs only for their listed uses.
Separate output from the unknown input rating
The product page states 1,250 W of microwave output and inverter operation. Output is the cooking-power value used in the roster's comparison. The exact SR electrical input and current were not established from a manual tied to this suffix, so do not substitute figures from NN-SN966S or infer an outlet requirement. Check the exact unit nameplate and its own documentation before installation.
Check dish fit rather than assuming tray capacity
Panasonic states a 2.2-cu.-ft. cavity, a meaningful size marker for larger cookware, but the sources reviewed here do not give an exact SR turntable diameter. A larger cavity does not guarantee that a wide rectangular dish can rotate without contacting the walls. Measure the glass tray and test the cookware dimensions against the actual oven before relying on a rotating cycle.
Treat the historical Amazon code as a search lead
The 2023 record supplies ASIN B07JMW8193 and an NN-SN966SR title, but its Amazon page returned an internal error during this review. That does not prove a current listing, exact condition or included accessories. The affiliate destination is therefore a tagged search for the model code. Compare the code and physical finish in any result before purchase; commercial-duty classification is also not established.
