Our take
RCA RMW742-White is a small white countertop microwave with a documented 0.7-cu.-ft. cavity and 700-W output. The manual itself names RMW742, while the frozen source title/model field says white and RMW742-White; a separate exact-name listing corroborates that color variant. Keep it distinct from the larger RCA RMW1132-WHITE because the model codes and capacities differ. The RMW742 manual lists 1,050 W microwave power consumption separately from 700 W output, so the higher number is not the cooking-power rating. Its controls include speed defrost, weight-based cook/defrost, multi-stage cooking, child lock and quick keys for common foods. The manual does not establish humidity-sensor cooking, a trim-kit path, commercial classification or a turntable diameter. Historical ASIN B005PON90Y returned HTTP 500, so the purchase link searches for the exact white model rather than presenting that ASIN as confirmed.
Consider RMW742-White if a small 0.7-cu.-ft. white microwave with 700-W output suits the dishes and countertop you have. Measure the appliance and the widest plate you expect to use, because the manual provides a turntable system but no diameter in the reviewed specification. Use the tagged exact-model search and confirm the RMW742-White code in any result..
Do not choose it for a known turntable-diameter requirement, sensor cooking, built-in installation or commercial-foodservice duty without separate documentation. If you need more cavity room than 0.7 cu. ft., compare a larger exact model and check its actual dimensions.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The RMW742 manual states a 0.7-cu.-ft. capacity and 700-W output, while separately identifying 1,050 W as power consumption.
- Speed defrost, cook-by-weight, defrost-by-weight and multi-stage cooking give the manual more usable detail than the generic microwave label alone.
- Named quick-cook controls cover popcorn, potato, pizza, beverage, frozen dinner and reheat; the model also has a child lock.
- The white RMW742-White identity is supported by the frozen source and independent exact-name corroboration rather than inferred from the manual's family code.
What to weigh up
- The readable manual specification does not give a turntable diameter or usable dish width, so measure the actual appliance and plate clearance.
- Preset cooking keys are not proof of humidity-sensor cooking; the manual does not identify a sensor feature.
- A model-specific built-in trim kit and commercial-duty classification were not found in the reviewed manual.
- The historical Amazon ASIN returned an internal error, so the affiliate route must be an exact RMW742-White search.
The key details
| Model covered | RMW742-White |
|---|---|
| Capacity | 0.7 cu. ft.; do not fill in unverified exterior or cavity dimensions. |
| Microwave output | 700-W microwave output, separate 1,050-W consumption, 120 V/60 Hz. |
| Cooking approach | Timed, multi-stage, quick-cook, and defrost controls; sensor cooking is unconfirmed. |
| Installation options | Manual documents flat, stable countertop placement; no model-specific trim kit is established. |
| Finish and turntable | White RMW742-White; a turntable system is documented, but diameter is unknown. |

What the features mean for you
Keep the exact white model code visible
The frozen source identifies RMW742-White and describes the oven as white. The manual cover names the underlying RCA RMW742 model but does not provide a suffix-to-color key. A separate lot title spells out RCA RMW742-White, 0.7 cu. ft. and 700 W, corroborating the source's exact variant clue. This is a small white RMW742 variant; it is not a renamed RMW1132-WHITE or a generic RCA compact microwave.
Compare cooking output separately from wall draw
RCA's specification table lists 700 W under Output and 1,050 W under microwave power consumption, with 120 V/60 Hz supply. Use 700 W when comparing cooking output with other ovens; the consumption figure describes the electrical load. The listed cavity is 0.7 cu. ft., so check whether the food containers you use fit that volume rather than assuming size from the product title alone.
Use the documented controls for small everyday tasks
The manual describes time entry, adjustable power, multi-stage cooking, speed defrost, cook-by-weight, defrost-by-weight and a child lock. Its quick-cook pages name popcorn, baked potato, pizza, beverage, frozen dinner and reheat. These are concrete control options; they do not by themselves demonstrate automatic humidity sensing. The manual does not name a sensor feature, so the profile leaves sensorCooking unknown.
Measure plates and counter space directly
The manual says to place the unit on a flat, stable surface and lists a turntable system, but it does not state the turntable diameter in the readable specifications. It also does not provide a reliable full outside measurement in that extracted text. Check the appliance label/manual copy for your unit and measure the widest dish base and handles before deciding that a plate will rotate freely.
Leave installation and duty questions open
The RMW742 manual provides countertop placement guidance but does not identify a compatible trim kit or assign a commercial-foodservice classification. Those attributes remain unknown rather than being inferred from the RCA brand, a household-looking size or the quick-cook controls. If cabinetry or professional service is essential, select a model with explicit manufacturer documentation for that use.
Search by full model because the source ASIN failed
The frozen ASIN B005PON90Y returned an internal server error when checked on 2026-10-05. The current exact ASIN/variant relation therefore remains unknown. The tagged search uses the full RMW742-White code so the buyer can verify the exact white model in Amazon results; it makes no claim about present offer, price or stock.
What else to compare
If you need more room, compare a larger exact model such as RCA RMW1132-WHITE and check its own documented cavity and tray measurements; the two model codes are not interchangeable. If sensor programs, built-in mounting or commercial service are firm requirements, select a microwave whose exact manual or maker page documents those features.
Before you buy
What are the capacity and microwave output?
RCA lists a 0.7-cu.-ft. capacity and 700-W output. It separately lists 1,050 W microwave power consumption at 120 V/60 Hz.
What does the RMW742-White suffix mean?
The frozen source calls the product white, and an exact-name secondary record says RMW742-White. The manual names RMW742 but does not provide a color-suffix key.
Does it have sensor cooking?
The manual lists quick-cook controls but does not identify a humidity-sensor feature, so sensor status is unknown.
How large is the turntable?
The manual says it has a turntable system but does not state the diameter in the reviewed specification. Measure the actual tray and dish clearance.
Can it be installed in cabinetry or used in foodservice?
The reviewed manual does not identify a trim kit or a commercial-duty rating; neither attribute is treated as confirmed.
Does ASIN B005PON90Y match this model?
Its page returned HTTP 500 on 2026-10-05. Use a tagged search for the exact RCA RMW742-White model and confirm the code in the result.
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.

The decision
Choose RCA RMW742-White if its small 0.7-cu.-ft. cavity, 700-W output and documented quick-cook/defrost controls match your use. Treat 1,050 W as consumption, not cooking output. Measure the appliance and tray because the manual gives no turntable diameter, and do not assume sensor cooking, a trim kit or commercial duty. The tagged exact-model search is used because historical ASIN B005PON90Y did not load.
