Product Details

Description

Ensure your heating system operates safely and efficiently with this 3-inch high limit control switch. Designed for HVAC and furnace applications, this thermal limit switch serves as a critical safety component that monitors internal temperatures within the heat exchanger. It is engineered to automatically interrupt power if the temperature exceeds the safety threshold of 220°F, preventing potential damage from overheating. Once the temperature cools by a 30°F differential, the switch automatically resets to restore normal operation. This high-quality replacement part is essential for troubleshooting furnace short-cycling or system shutdowns, providing reliable climate control and long-term protection for your heating equipment.
