Description

Ensure the safe and efficient operation of your heating system with this professional-grade 7-inch insert high limit control switch. Designed as a critical safety component for residential and commercial HVAC units, this auto-reset limit switch monitors internal air temperatures to prevent overheating within the furnace plenum. The L240-30F rating signifies that the switch will automatically interrupt the heating circuit if temperatures reach 240°F and will reset once the temperature drops by 30°F. This replacement part is essential for fixing furnaces that are short-cycling or failing to provide consistent heat due to a faulty thermal sensor. Its durable construction and precise temperature calibration make it a reliable choice for maintaining climate control systems and protecting against thermal overloads.
