Description
The Trane BRD00742 Defrost Module Printed Circuit Board is an electronic control component used to regulate cycles in the heat pump in HVAC systems. Its main role is to check temperature and pressure inputs on the outer coil and activate programs to ensure efficient working conditions. This module works under the concept of integrated circuitry sensor data and transmits control to reversing valves and auxiliary heat. It fits in the control compartment of the outside unit and is wired into the system control harness.
