Product Details

Description

Ensure your heating system operates safely and efficiently with this high-quality 3-inch high limit control switch. Designed to monitor the internal temperature of your furnace or heating unit, this thermal safety switch acts as a critical protection component. It is engineered to automatically cut power to the burners if the heat exchanger exceeds safe operating temperatures, preventing overheating and potential equipment damage. Featuring standard L240-30F specifications, it opens the circuit at 240°F and automatically resets once the temperature drops, ensuring consistent performance. This reliable replacement part is essential for routine HVAC maintenance and furnace repair, providing a necessary layer of protection for residential and commercial heating systems.
