Garage door opened, won't close

I have a 1/2 hp Craftsman opener model 139.53635SRT1. Motor worked fine to raise door, when remote is pushed to lower door nothing happens. Electric is working, no obstructions. I waited 15 minutes to see if the overload protection has tripped. (waited and tried several times). When press the wall control the light on the opener comes on and the unit clicks once, but nothing. The same thing happens when I try the remotes.

    I have the same problem, my craftsman garage door opened and now it wont go. The electric is still working and the lights still work. It makes a slight "buzz" sound and then nothing. Just like the other problem - there are no obstructions or rail issues that I can see. I tried holding the wall unit button downn - but did not work.

If you can press and hold the wall button and the door will go down, you have a photo eye issue. Check the photo eyes at the bottom of the door.

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.

If you didn't install the door sensors you must. If you did, make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little.

Garage door only raises about two inches then stops.

Check the door springs and also remove the cover from the motor unit and check the drive gear. The door spring could be broken or the drive gear may be stripped.

The sensors only work when the door is closing.

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.

Craftsman 1/2 HP garage opener opens only 6 inches

Remove the cover and check the drive gear. It is white nylon and is just in front of the motor. It may be stripped. Take a close look at those door springs. They can sometime appear to be okay when one is broken.

Have to hold the push button inside my garage to close garage.

You have a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not blinking. Also check the wiring.

I have no idea what a 132C2105-3B is but try this. Hold the button down on the remote and then press and immediately release the smart/learn button. If the remote is the correct one for your opener it should work.
