23X17 | Lennox 620244-02, Defrost Control Board | Lennox

Lennox Defrost Control Board (23X17) This Lennox Defrost Control Board (part number 23X17) is designed to regulate the defrost cycle of refrigeration and cooling systems. Its primary function is to monitor temperature and initiate the defrost process when the evaporator coil becomes iced over, ensuring optimal system performance. The Defrost Control Board operates by sensing the temperature of the evaporator coil. When the coil温度falls below a predetermined set point, the board activates the defrost system, typically consisting of heaters or hot gas. This process melts away the ice and frost buildup, restoring proper airflow and heat transfer within the system. The Lennox Defrost Control Board is a crucial component for maintaining the efficiency and reliability of cooling and refrigeration systems. Its advanced control capabilities help optimize defrost cycles, minimize energy consumption, and prevent damage to the system's components. To ensure proper operation, the Lennox Defrost Control Board should be installed and configured by a qualified technician. It is recommended to regularly inspect and maintain the control board to ensure optimal performance and extend its lifespan.
