WB20X10048 - GE Microwave Thermostat

This GE Microwave Thermostat (WB20X10048) is a genuine part for GE microwaves, ensuring compatible fit and performance. The thermostat measures internal air temperatures to regulate cooking power, efficiently preventing overheating or components from damages. It features bimetallic flexing contacts which open or close as temperatures cross set thresholds, providing thermal protection and regulation. Some models include smart thermostats that dynamically control magnetron outputs during operation, while simpler versions offer essential overheat protection. Common symptoms indicating a failing thermostat include inconsistent microwave performance, overheating issues, or the microwave ceasing operation due to safety shutdowns. Replacing a defective thermostat is necessary to maintain the safety and efficiency of your microwave. Remember to verify your microwave's model number for compatibility before purchasing.
