WB20X10052 - GE Microwave Thermostat

This GE Microwave Thermostat (WB20X10052) is a genuine part specifically designed for GE microwaves. This component plays a critical role in your microwave's operation by measuring internal air temperatures to regulate cooking power, thus preventing overheating or damage to other components. Its bimetallic flexing contacts open or close as temperatures cross set thresholds, making it essential for both thermal protection and power regulation. While simple thermostats provide overheat protection, this advanced version dynamically controls the magnetron outputs during operation. If your microwave starts acting up, such as not heating correctly or turning off unexpectedly, it might indicate that the thermostat is defective and needs replacement. Before purchasing, make sure to verify your microwave's model number to ensure compatibility.
