The drive gear is most likely stripped. It is a white nylon gear just in front of the motor. The parts number is 41A2817 and is available from Sears or any good door opener service company. It comes with instructions.

What does the purple button light flashing on 1/2 horsepower craftsman garage door opener


I think the adjustment mode is on.

For example, that's from Craftsman manual:

""
Setting the Force
The force setting button is located on the left panel of the motor unit. The force setting measures the amount of force required to open and close the door.
1. Locate the purple button on the left panel of the motor unit (Figure 1).
2. Push the purple button twice to enter the opener into Force Adjustment Mode (Figure 2). The LED (Indicator Light) will flash quickly.
3. Push the remote control or control console (Figure 3). The door will travel to the DOWN (close) position.

""

Actually, you should just read carefully your garage door opener unit's manual.

I installed a Craftsman garage door a couple of weeks ago and all of a sudden it keeps opening by it's self. It is model #139.53918D what is causing this?


Make sure the door isn't closing too far. This will cause it to open. Your opener comes with a warranty. Call Sears repair.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

Make a slight adjustment to the Upward force on the side of the machine. Turn the screw a 1/4 turn each time and test, see if that helps. Also, make sure there are no obstructions or friction when the door opens and closes. Try it manually first.
