Trane CNT4363 Defrost Control Board

The Trane CNT4363 Defrost Control Board is designed to fit select Trane systems. The defrost control board 4501300013 replaces the original defrost control 4501300015 and controls the defrost cycle of Trane air conditioners and heat pumps. This defrost control board also monitors the building temperature, provides remote diagnostics, and has an advanced overheat system that protects against faulty wiring or circuit failures.

The defrost control board is designed for the Trane Air Handler. What are the features?

The Control Board is located inside the Heat Pump outdoor unit and controls defrost operation.

The Trane CNT4363 Defrost Control Board is an important component of your HVAC unit, which keeps the system operating at peak efficiency. The defrost control board and defrost heater work together to prevent ice from building up on the evaporator coil. Failure to replace both components simultaneously can lead to overheating and the failure of the system.

Designed for use with Trane heating and cooling systems, this defrost control board is made under strict quality control procedures and comes with a 5-year limited warranty. The defrost control measures the temperature of the plate on the evaporator coil. When temperatures drop below 55°F, it triggers the defrost cycle to protect against frost damage and extend the life of your furnace. This defrost board is compatible with either Trane's ComfortNet or MicroNet system, and offers quick installation.
