The Frigidaire 137009010 Electronic Control Board manages dryer settings, cycle timing, and key electrical functions for consistent drying. This replacement board receives signals from the control panel and sensors, then sends commands to connected components such as the heating system, motor, timer, and other dryer circuits. It coordinates selected cycle settings and controls the timing and temperature functions according to the dryer configuration. A faulty board may cause unresponsive controls, incorrect cycle selection, heating problems, or inconsistent drying.
