Description
The Trane CNT3514 is an OEM auto-reset cutout (CO) limit switch designed to protect Trane heating and HVAC systems from dangerous overtemperature conditions. Calibrated to open at 190°F, this limit switch interrupts the control circuit when excessive heat is detected, shutting down the burner or heating element to prevent equipment damage and potential safety hazards. Once temperatures return to a safe operating range, the switch automatically resets, restoring normal system operation without requiring manual intervention.
As a genuine Trane replacement part, the CNT3514 is engineered to exact OEM specifications, ensuring reliable fit and function in compatible Trane furnaces and air handling equipment. Keeping this critical safety component in proper working order is essential for maintaining system efficiency, equipment longevity, and occupant safety.
