Our take
RCA's official page supports the white 1.1-cu.-ft. RMW1129WHITE identity, and the exact-variant manual spells the model RMW1129-WHITE and gives the practical operating details. It lists 1,000 W microwave output separately from 1,500 W input, with 120-V/60-Hz supply. The manual describes a turntable system, ten power levels, preset quick cooking, express keys and several defrost and staged-cooking controls. It does not establish a turntable diameter, sensor cooking or trim-kit compatibility. Its installation guide calls for a stable flat surface and substantial surrounding air space. The historical Amazon ASIN did not load, so the tagged exact-model search avoids claiming a verified direct ASIN.
A white household countertop microwave for a measured location that can accommodate the 21 1/4-in. body width and the manual's ventilation gaps..
Choose another model if you need confirmed sensor cooking, a known tray diameter, a documented cabinet trim kit or a larger measured cavity. For foodservice use, require a model explicitly classified for that duty.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- RCA's official listing confirms the white RMW1129WHITE variant and 1.1-cu.-ft. capacity; the exact manual uses the hyphenated RMW1129-WHITE code.
- The manual distinguishes 1,000 W microwave output from 1,500 W power consumption and provides external and cavity dimensions.
- Ten selectable power levels and express cooking give manual timing options alongside food presets.
- The control set includes time and weight defrost and multi-stage cooking sequences.
What to weigh up
- RCA's manual asks for about 20 cm above, 10 cm behind and 5 cm at each side, so the microwave needs more than its listed body footprint.
- A turntable system is shown, but the reviewed sources do not give its diameter; dish fit needs separate confirmation.
- Quick-cook programs are documented, but the sources do not say that cooking is sensor-adjusted.
- No model-specific trim kit is established, and the historical Amazon ASIN returned an internal error.
The key details
| Model covered | RMW1129-WHITE |
|---|---|
| Capacity | RCA identifies the white RMW1129WHITE as a 1.1-cu.-ft. microwave; the exact-variant manual uses RMW1129-WHITE |

| Cooking approach | Outside dimensions are 11 13/16 × 21 1/4 × 16 5/16 in. (H × W × D); cavity dimensions are 9 7/16 × 13 15/16 × 14 1/8 in. |
| Installation options | Controls include ten power levels, preset quick cooking, express cooking, time/weight defrost and multi-stage programs |
| Finish and turntable | Installation instructions require a flat, stable surface and about 7.9 in. above, 3.9 in. behind and 2 in. at each side |

What the features mean for you
Match the hyphenated white model carefully
The frozen source calls this model RCA RMW1129-WHITE. The exact-variant manual cover uses the same hyphenated code, while RCA's official product page omits the separator and names it RMW1129WHITE; that official page also says white and 1.1 cu. ft. These spellings support the same white variant, but they do not prove that the historical Amazon B08R51HD83 page still leads to it. That direct page returned an internal error. Use the tagged search for the complete RMW1129-WHITE model and confirm the white finish in a result before relying on a listing.
Measure the cavity and outside dimensions
RCA's official listing gives a nominal 1.1-cu.-ft. cavity. The exact-variant manual lists outside dimensions of 11 13/16 inches high, 21 1/4 wide and 16 5/16 deep, with interior dimensions of 9 7/16 by 13 15/16 by 14 1/8 inches. Those measurements are more useful for checking shelf clearance and typical containers than capacity alone. The manual confirms a turntable system and glass tray, but does not provide the tray diameter. Keep that fit question open and measure the dish rather than assuming that its rim clears the cavity walls.
Separate cooking output from electrical input
The manual lists 1,000 W output and a separate 1,500 W consumption figure, along with a 120-V, 60-Hz supply. The 1,000-W value is microwave cooking output; the 1,500-W figure is input power and should not be substituted for a cooking-output comparison. The manual's grounded-plug and installation instructions govern connection and placement. Follow those instructions for the electrical setup instead of deriving a circuit decision from output watts alone.
Preset cooking does not establish sensor control
The manual documents ten power levels, Express Cook, Quick Cook presets for foods such as potatoes, popcorn and beverages, time and weight defrost, and multi-stage cooking. Those controls offer a mix of shortcuts and user-entered settings. The manual describes presets as timed or portion-based settings, but does not identify a sensor system that measures food moisture or adjusts cooking automatically. Keep sensorCooking unknown rather than treating an automatic menu as proof of sensing.
Leave room for ventilation
The operating instructions call for a flat, stable surface and specify about 20 cm above, 10 cm at the back and 5 cm at each side. These gaps add several inches to the microwave's 21 1/4-inch body width and 16 5/16-inch depth. Check the full space before placing it on a counter or shelf and keep openings clear. The manual's countertop placement instructions do not verify an optional trim kit; the reviewed materials do not state a compatible cabinet kit, so trimKitCompatible stays unknown.
Treat the manual as a household-use limit
The exact-variant instructions say the oven is for heating, cooking or drying food and is not designed for industrial or laboratory use. That supports keeping it out of foodservice recommendations. The manual gives operating instructions, not measured heating performance or durability testing, so this review makes no claim about real-world speed, lifespan or consistency. Sensor cooking, trim-kit compatibility and turntable diameter remain unresolved from the sources inspected.
Use a model search instead of an unverified ASIN
The historical Amazon B08R51HD83 detail page returned an internal error when reopened. The affiliate destination therefore searches for RCA RMW1129-WHITE and includes buyershortlists-20, with no claim that a direct Amazon ASIN has been verified. Confirm the exact white suffix and compare the model code in any result. The official RCA page and operating manual are the evidence for identity and specifications; no current price, stock, sales or customer-review statement is made.
What else to compare
If the manual's ventilation space or 1.1-cu.-ft. cavity does not fit, compare a model with a smaller outside body or larger measured capacity. For sensor cooking, a known turntable size or cabinet-kit installation, require exact-model documentation of that feature. For foodservice, select an oven whose maker explicitly classifies it for commercial duty.
Before you buy
What is the RCA RMW1129-WHITE's capacity and output?
RCA's official listing gives 1.1 cu. ft.; the exact-variant manual lists 1,000 W microwave output and separate 1,500 W input.
Is the RMW1129-WHITE the white variant?
Yes. The exact manual names RMW1129-WHITE and RCA's official RMW1129WHITE page lists the color as white.
Does it have sensor cooking?
The manual lists quick-cook presets but does not document sensor cooking, so the sources do not establish sensor cooking.
What size is its turntable?
The manual confirms a turntable system and glass tray but does not state a diameter.
Can it be installed with a trim kit?
The sources reviewed document countertop ventilation clearances but do not identify a compatible trim kit.
Does Amazon ASIN B08R51HD83 directly match the model?
Its page returned an internal error; use the tagged exact-model search and check for RMW1129-WHITE in the result.
Where can I check the current price?

The decision
RCA's official listing and exact-variant manual support the white RMW1129 model, 1.1 cu. ft. and 1,000 W microwave output. The manual separates output from 1,500 W input, gives dimensions and explains ten power levels, quick presets, defrost and staged cooking. It requires ventilation clearance and does not document sensor cooking, a tray diameter or a trim kit. Because the old Amazon page failed, use the tagged exact-model search.
