Craftsman Garage Door Opener Problem
Have a 1/2 HP Craftsman Garage Door Opener (41A5021-2D). Wife opened the garage the other night but when she went to lower it with wall switch, the unit only makes a click and lights come on (no flashing). No movement to move the chain. The yellow (amber) light next to red square switch flashes 5 times then pauses then flashes 5 times again. Would the circuit board be the problem? Sensors at Door bottom are solid green so they should not be the problem. Any advice would be appreciated.
