Description
The Trane BRD 4721 is a Trane fan board that is equipment in HVAC systems that control airflow. It is an electronic circuit board as the blower fan’s. The fan board receives signals from your thermostat and then uses those signals to decide how fast and in what direction the fan should run. The Trane can move 400 CFM of air in a minute. Once you know the fanboard needs to be working for the HVAC system to run properly and comfortably. If your home’s temperature is up and down, air quality is poor, and energy use is going up, it may be because of a fan board that’s not working.
