Ensure the safety and efficiency of your heating system with this premium Lennox Auto-Reset High Limit Switch. This critical HVAC safety component is designed to monitor the temperature within the heat exchanger, providing essential protection against overheating. Featuring a 7-inch insertion probe for precise thermal detection, the switch is calibrated to automatically interrupt the heating cycle if temperatures reach 220°F and will automatically reset once the unit cools by 30°F. Ideal for furnace repair and maintenance, this limit control helps prevent damage to the heat exchanger and ensures your forced-air system operates within safe thermal parameters. If your blower fan is running constantly or your burner is cycling off prematurely, this high-limit control switch is a reliable solution for restoring peak performance.
