About the GE GCST20A1WSS

Designed as a standard countertop microwave at 29.9" wide, this model provides reliable everyday heating with a 2.0 cu ft cavity that accommodates casseroles, large plates, and standard meal portions. Equipped with sensor cooking, this 1200W microwave monitors moisture levels and stops heating at the exact moment food is ready, eliminating the most common microwave mistake and delivering consistently better results. The manufacturer specifies 3.0" clearance above, 3.0" on each side, and 3.0" behind for safe operation and heat dissipation; confirm your installation location can accommodate these requirements. The right pick for households that cook in quantity—this interior size handles 13×9 baking dishes and the large bowls that smaller models can't spin.
