Description
The Trane CNT09379 is an OEM high limit control designed to protect heating equipment from dangerous overtemperature conditions. With a precisely calibrated open setpoint of 205°F and a close setpoint of 175°F, this limit control automatically interrupts the heating circuit when temperatures exceed safe operating thresholds and resets once temperatures return to the safe range.
High limit controls are a critical safety component in furnaces and air handlers, preventing heat exchanger damage, equipment failure, and potential fire hazards caused by overheating. The CNT09379 is engineered to Trane’s exacting OEM standards, ensuring a direct-fit replacement that maintains the original performance and safety specifications of your Trane system.
