Product Details

Description

Ensure the safety and efficiency of your heating system with this 3-inch furnace high limit switch. Designed as a critical thermal protection component for residential gas furnaces and HVAC units, this high limit control monitors the temperature of the heat exchanger. It acts as a safety cutout, automatically interrupting the heating cycle if the internal temperature reaches 220°F to prevent overheating and potential equipment damage. Once the temperature drops by 30°F, the switch resets to resume normal operation. This reliable replacement sensor is essential for troubleshooting furnace short-cycling or safety shutdown issues, providing peace of mind and maintaining optimal climate control performance in forced-air systems.
