What are the common symptoms of a bad LiftMaster 030DCT circuit board?

Typical symptoms of a failing LiftMaster 030DCT circuit board include the opener having no power or response even though the outlet is live, intermittent or random operation, the door reversing or stopping unexpectedly, remotes or wall controls not working while safety sensors are properly aligned, clicking sounds without motor movement, and visible signs of board damage such as burnt components, corrosion, or discoloration. These symptoms often persist after basic troubleshooting has ruled out wiring issues, sensors, remotes, and power supply problems.
