Product Details

Description

This 3-inch high limit switch is an essential safety control designed for gas-fired furnaces and heating systems. Acting as a critical thermal safeguard, this sensor monitors the air temperature within the heat exchanger. If the system reaches an unsafe operating temperature, the switch automatically interrupts power to the heating circuit, preventing overheating and protecting your HVAC equipment from potential damage. This limit control is engineered to open the circuit at a fixed temperature of 200°F and features a 30°F differential, allowing the system to reset once it has cooled to a safe level. It is a vital replacement part for maintaining the safety and efficiency of residential and commercial forced-air heating units during the winter months.
