WB21X10149 - GE Microwave Thermostat

This GE Microwave Thermostat (WB21X10149) is a genuine part designed to fit your GE microwave. It measures internal air temperatures to regulate cooking power, effectively preventing overheating or component damage. By employing bimetallic flexing contacts, the thermostat opens or closes as temperatures cross set thresholds. While simple thermostats offer basic overheat protection, this smart thermostat dynamically controls the magnetron's output during operation, ensuring your microwave runs smoothly. If you've noticed your microwave overheating, failing to heat evenly, or experiencing power regulation issues, it may be time to replace the thermostat. A defective thermostat can no longer provide the necessary thermal protection and regulation, which is essential for your microwave's performance. Before purchasing, please verify your device's model number to ensure this part is compatible.
