Product Details

Description

This 3-inch high limit switch is a critical safety component designed for forced-air heating systems and gas furnaces. Engineered to monitor internal heat exchanger temperatures, this thermal control switch acts as a failsafe by automatically interrupting power to the burner or heating element if the unit exceeds safe operating limits. With a cut-out temperature of 260°F and a 30°F reset differential, it ensures your HVAC equipment remains within a safe thermal range, preventing damage to the system and ensuring home safety. This replacement limit control is ideal for restoring reliable operation to furnaces experiencing cycling issues or overheating due to restricted airflow.
