Description
The Trane CNT4365 is an OEM defrost control designed for use in Trane heat pump systems. It manages the automatic defrost cycle to prevent ice buildup on the outdoor coil, ensuring consistent heating performance even in cold-weather conditions.
How It Works
During heating operation, frost can accumulate on the outdoor unit’s coil, reducing system efficiency. The CNT4365 defrost control monitors system conditions and initiates a timed or demand-based defrost cycle, temporarily reversing refrigerant flow to melt frost accumulation. Once defrost is complete, the control returns the system to normal heating mode — all without manual intervention.
