Our take
Amana AMC5143AAS is a stainless 1.4-cu.-ft. countertop microwave with 1,100-W output, ten power levels, sensor cooking, and 120-V/60-Hz supply. Its exact owner manual identifies the AAS model, states household use, and allows an optional trim-kit installation; a matching model record confirms sensor cook and sensor reheat. The manual's AAS dimensions help with counter fit, but the exact turntable diameter and electrical input wattage remain unknown. Historical ASIN B000ZINO9Q was not confirmed to this exact model, so use the tagged full-code search.
Compare AMC5143AAS when sensor cooking, a 1.4-cu.-ft. stainless cavity, and a documented optional trim path matter; check the opening, exact suffix, and outlet circuit..
Choose a larger model if you require at least 1.5 cu. ft.; choose another exact profile if tray diameter or electrical input is a must-have, since neither is confirmed here.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Amana's exact AAS manual lists 1.4 cu. ft., 1,100-W output, ten levels, and a 120-V/60-Hz power source.
- The manual and exact-model record document sensor cooking and reheating rather than leaving that feature to a generic family description.
- The base unit is a countertop model, and the exact owner manual documents a separate optional trim-kit route.
What to weigh up
- The cavity is below the finder's 1.5-cu.-ft. large-size requirement even though it is larger than the 0.8- and 0.9-cu.-ft. models.
- The reviewed sources do not state an exact tray diameter or electrical input wattage for AMC5143AAS.
- The optional trim kit is separate, and the historical Amazon ASIN has no confirmed exact-model mapping.
The key details
| Model covered | AMC5143AAS |
|---|---|
| Capacity | 1.4 cu. ft. cavity; outside dimensions are about 21 7/8 in. wide, 12 15/16 in. high, and 18 19/64 in. deep; tray diameter is not established. |
| Microwave output | 1,100 W microwave output; the reviewed exact model sources do not establish electrical input wattage. |
| Cooking approach | Sensor Cook and Sensor Reheat controls, ten power levels including defrost, and automatic weight defrost are documented. |
| Installation options | Countertop use with 120 VAC / 60 Hz supply; the owner manual documents an optional separate trim-kit route for built-in installation. |

What the features mean for you
Why keep the full AAS code?
Amana's owner manual names AMC5143AAS as its own model code alongside AMC5143AAB/W/Q and AMC5143BCB/W/Q variants. The frozen title also names AMC5143AAS and stainless steel, and the exact product record confirms the stainless countertop version. Keep AAS intact when checking a result; the shared 5143 family name does not prove another suffix has the same finish, power, control panel, or accessories. The historical B000ZINO9Q mapping was not established, so the purchase link searches the complete AAS model code rather than assigning that old ASIN to this record.
What fits inside the 1.4-cu.-ft. cavity?
The exact manual lists a 1.4-cu.-ft. cavity and outside dimensions of about 21 7/8 inches wide, 12 15/16 inches high, and 18 19/64 inches deep for the AAS model. Those figures can help with a shelf or counter check, but the manual does not give a confirmed turntable diameter in the reviewed specification table. Measure the dishes you use and leave room for them to move inside the cavity; do not derive tray size from capacity or exterior depth. A 1.4-cu.-ft. oven is a middle-size option, not a match for a stated 1.5-cu.-ft. minimum.
How should the 1,100-W rating be compared?
Amana lists 1,100 watts as microwave output and specifies 120 VAC at 60 Hz, but the exact sources reviewed do not state electrical input watts. Use 1,100 W as the cooking-output figure when comparing it with other verified outputs; do not invent an input number from that value. The supply documentation establishes voltage and frequency only. Check the actual unit rating plate and outlet circuit before installation, particularly if a dedicated outlet or another electrical condition matters in your kitchen. This profile does not promise a specific cooking time or measured result.
What does sensor cooking add?
The exact Amana control-panel manual identifies Sensor Cook and Sensor Reheat, and the model-specific record lists eight sensor-programmed pads. Those functions distinguish this model from a microwave that offers only time and power entry or generic auto menus. They can be useful for the food and quantities covered by the manufacturer's programs, but they are not evidence that every container, serving size, or recipe is automatic. The ten manual power levels, including defrost, are also documented for users who want to select settings themselves. The source does not support a performance claim beyond these listed controls.
Can the countertop unit be fitted into cabinetry?
Amana's exact owner manual describes the oven resting on a flat, sturdy surface and documents optional trim-kit installation as a separate configuration. That gives AMC5143AAS more documented installation flexibility than a model whose manual only permits freestanding use. It does not mean a trim kit is included, that any generic kit fits, or that the surrounding cabinet opening is suitable. Confirm the part number, cabinet dimensions, ventilation requirements, and current unit instructions before planning a built-in look. If it will stay on the counter, the documented 120-V/60-Hz supply still needs a proper grounded outlet and a circuit check.
What remains unknown before ordering?
The exact turntable diameter and electrical input wattage remain unavailable in the reviewed AAS sources, so neither belongs in a hard match or a numeric comparison. The historical candidate ASIN also did not establish the current listing-to-model crosswalk. The tagged search uses the model code and lets a shopper inspect any current offer, but it does not establish price, inventory, condition, or package contents. Compare this Amana with another model if you need a documented tray size or a direct Amazon model proof. The supported strengths are its sensor programs, capacity, output, supply, and optional trim route.
What else to compare
GE JES1460DSWW is another sensor-equipped 1.4-cu.-ft. countertop microwave with 1,100-W output and a 12.625-in. tray, but its reviewed exact record does not establish a trim-kit route. Amana AMC5143AAS documents an optional kit instead, while its tray diameter and input watts remain unknown. Compare sensor controls, installation plans, and cookware measurements before choosing between them.
Before you buy
Does AMC5143AAS have sensor cooking?
Yes. The exact model's control manual documents Sensor Cook and Sensor Reheat, and the product record lists sensor-programmed pads.
What is its stated microwave output?
The Amana manual lists 1,100 W microwave output for the exact AMC5143AAS model.
What electrical supply is documented?
The manual lists 120 VAC at 60 Hz; it does not establish electrical input wattage for this exact model.
Is a trim kit supported?
The exact owner manual documents an optional separate trim-kit route; check kit and cabinet-opening compatibility.
Is the turntable diameter known?
No exact diameter was confirmed in the reviewed AAS documentation, so measure the dishes and check the actual tray.
Where can I check the current price?
