Product Details

Description

The 3-inch High Limit Switch L150-20F is an essential safety component designed for modern heating systems and gas furnaces. This thermal limit control acts as a crucial failsafe by monitoring the internal temperature of the heat exchanger. If the system detects overheating, the switch automatically interrupts the circuit to shut down the burner, preventing equipment damage and ensuring home safety. This high-quality replacement part is ideal for HVAC maintenance and repair, helping to restore efficient operation to units experiencing short-cycling or safety-related shutdowns. Its 3-inch probe design allows for precise temperature sensing within the airflow of residential forced-air furnaces.
