Insignia™ - .9 Cu. Ft. Compact Countertop Microwave - Stainless Steel

Thank you for your inquiry! Yes, it is normal for the Insignia™ .9 Cu. Ft. Compact Countertop Microwave to beep only once at the end of the cooking time. This single beep is designed to signal that the cooking cycle has completed. Unlike some other microwaves that may have multiple reminder beeps, this model typically only provides one beep.

Hi there. It's generally not recommended to open the microwave door while it is cooking, even if there is a safety mechanism in place. The safety interlocks are designed to prevent the microwave from operating when the door is open, which helps avoid exposure to microwave energy. If you need to stop the cooking process, it's best to press the "Stop" or "Pause" button on the microwave before opening the door. This ensures that the microwave stops emitting energy before you open it. If you have any further feedback or need assistance, please feel free to reach out. Ivy Insignia Support
