We have a 3/4 hp Craftsman garage door opener that has stopped working. It opened fine, but will not close. The lights on the unit work but the Training Light is blinking.

    Thanks Don. That is the light I am referring to. I don't think it is the sensors as they seem to be fine, one with a solid green light and the other with a solid yellow light. We have a repairman coming today to have a look. I'll let you know.

If by training light you mean the LED next to the smart/learn button then this is normal if it is random blinking. Make sure your door sensors are properly aligned and pointing at one another. Each of them has a small light that should be lit and not blinking when they are aligned.

SOURCE: I have a craftsman garage door opener (1/2 hp) won't close proper

Check your door sensors. They have probably been bumped. Tweak them until they are pointed at one another and the small light on each one is lit and not blinking.

I have a 1/2 hp craftsman opener. Remotes work fine. Wired wall unit has a blinking light on the open button and will not work Lock pad and light pad work but not the operate pad.????


Try pressing and holding the lock button for 3 seconds to stop the light from blinking. Your wall control may be bad. Usually when that light is blinking it is the remotes that will not work.

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.

Garage door opened, won't close


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.
