If the door is stuck in the open position it probably because the trolley is jammed against the bolt just in front of the motor unit. Remove the bolt and run the opener until the door is closed. On the side of the unit you will find an adjustment for the 'up limit'. Turn this about 3 turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

Post back if this isn't your problem.

The trolley is most likely jammed against the bolt just in front of the motor unit. Remove the bolt and then run the door until it is closed. Now locate the 'up limit' control on the side of the motor unit. Turn this 2 complete turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

The LED flashing 5 times is the code for "RPM sensor or motor overload". Usually if it is the RPM sensor - which is a small printed circuit board just in front of the motor - it will run a few inches and then reverse. I doubt very much it is the motor. I would pull the logic board and check for loose or missing traces on the printed circuit. Especially if you have had any electrical storms or power surges.

Craftsman Garage Opener Clicks only and LED blinking 5 times


Just fixed this problem tonight. Had the 5 blink/flash thing. Opened it up and saw that the motor wasn't spinning so it wasn't a bad rpm sensor. Jumped the red to black and then the blue to black to verify motor worked. At that point assumed it was the logic board not telling the motor to start, but I could hear the click of the relay. Pulled the logic board out and noticed a solder joint that had failed directly behind one of the relays. Resoldered that joint and the garage door opener worked again like a dream. Hope that helps someone else.
