Professional Repair Guide

What is this symptom?

Is your GE microwave continuing to operate even when the door is open? This alarming issue indicates a malfunction in the safety interlock mechanism. Typically, the microwave should stop functioning immediately upon door opening, and failure to do so can pose serious safety risks. Understanding the causes and solutions is essential to restore proper operation.
