Product Details

Description

Ensure the safety and efficiency of your heating system with this premium 3-inch high limit switch. Designed as a vital safety cut-out for residential furnaces and HVAC units, this thermal limit control prevents equipment damage by monitoring heat exchanger temperatures. The switch is engineered to open the electrical circuit if the internal temperature reaches a 210°F threshold, effectively shutting down the burner to prevent overheating. Featuring a 30°F differential, it automatically resets once the system has cooled to a safe operating level. This reliable replacement part is essential for maintaining consistent climate control and protecting your home's heating infrastructure from thermal stress.
