Cold Solder Joint
Separated from: http://www.doityourself.com/forum/ga...g-5-times.html
My 1/2 HP Craftsman garage door opener stopped working the other day and gave me the "led blinking 5 times" code. As I was working on it, I also noticed that the motor would turn in the door open direction (up), but not the door close direction (down). After researching the problem a bit, I located a cold (loose) solder joint on the logic board that seemed to be the culprit.
The solder joint is behind/near the transformer on the back of the unit, and it appears to be where a relay attaches. This particular connection also seems to trace to the multi-wire plug that everything attaches to - and more specifically, the red lead that goes to the motor-start capacitor.
After removing the two screws that hold the logic board to the frame, I was able to swing the board around for better access. I cleaned off the questionable solder joint and re-soldered it. Voila, problem solved! The door goes up and down now just like it always has!

Having similar problems. the liftmaster won't close unless i hold the wall button down continuously. if just hit once, travels a few inches and then reverses. will not respond to hand remote.
Anyone sort out the issue and how to fix?

light flashing 5 times
Mine was doing the same thing I unplugged for 5 minutes, and I also increased the opening and or closing force whichever is giving you the problem. My unit would not open so I increased the opening force, it worked immediately. I then reset the unit for the proper force.
