Description
The Trane SWT04399 Thermal Limit Switch is an OEM replacement safety component engineered to protect Trane heating and cooling systems from dangerous overtemperature conditions. When system temperatures exceed safe operating thresholds, this limit switch interrupts the circuit to prevent equipment damage, component failure, and potential safety hazards — then resets to restore normal operation once temperatures return to acceptable levels.
