Overview

The GE GCST20S1WSS is a countertop microwave oven that combines a roomy 2.0 cubic foot interior with 1200 watts of cooking power. That capacity is notably larger than the typical 1.1 to 1.6 cubic foot range found in most countertop microwaves, giving you the space to fit full dinner plates, large bowls, and casserole dishes without having to rearrange or use smaller containers. The glass turntable rotates during cooking to promote even heat distribution, and the 1200-watt output ensures food heats quickly whether you are reheating leftovers or cooking from scratch.

The sensor cooking controls are a practical convenience — they monitor moisture released by food during cooking and automatically adjust time and power to deliver consistent results. For defrosting, you can choose between weight-based defrost, where you simply enter the weight and let the microwave calculate the rest, or time-based defrost for more manual control. One-touch Instant On express cooking makes quick reheating effortless, and the 8 auto cooking presets cover common tasks. A two-step child lock adds safety for households with young children, and it can be deactivated when not needed. The kitchen timer and cooking complete alarms round out a straightforward, well-equipped countertop microwave built for everyday use.
