Description
The Trane CNT05010 Defrost Control Board is an electronic part that is used in HVAC heat pump systems to control the part cycle. It checks system conditions, and defrosts when frost is observed on the outside coil to maintain the correct heat exchange and airflow. It is typically fitted in commercial units and is linked to sensors and other controls to control timing and operation. This board is an essential in ensuring the efficiency of the system and avoiding performance problems due to ice formation during the colder operating conditions.
