Description
The Trane CNT4363 Defrost Control Board is a genuine OEM HVAC control module specifically designed for use in Trane heat pump systems to manage and optimize the defrost cycle. When frost builds up on the outdoor evaporator coil during cold weather operation, this control board accurately detects temperature changes and activates the defrost process to melt ice, helping maintain airflow, system efficiency, and reliable heat pump performance. This part is also sometimes referenced or replaced by the updated part number CNT04363.
