Garage Door Opener

Posted by robaroo (My Page) on

I have a 10 year old Craftsman 1/2 Hp garage door opener that is stuck about a 1/4 of the way open. When you push the opener, it moves 1 foot down and then 1 foot back up. I replaced the white gears but that did not solve the problem. When you release the garage door, it rolls up and down without any problems. When I turn the adjustment screws all the way up to 9 nothing changes.

I just noticed the yellow indicator light blinks 5 times. What does this mean? Thanks!

RE: Garage Door Opener

The indicator light blinking 5 times is "RPM sensor or motor overload". It isn't the motor or it wouldn't move at all. Try this:

Make sure you put the black cup back on the end of the motor shaft and that it is pressed all the way on. Make sure the RPM sensor is plugged in. If neither of these are the issue, then you probably did not have the motor shaft pushed all the way back when you tightened the coupler after replacing the worm gear. Loosen that coupler up and from the front of the motor (opposite end in which the coupler is on) push the shaft back as far as it will go. Hold it there while you tighten the coupler back up and then try it.

Moved into a home with Craftsman 1/2 HP opener with the craftsmans remotes and the remotes will not work so I Purchased two universal Clicker devices (CLT1D) mfg by Chamberlain. I would like the instructions on how to get the new clickers to work.

Go to this site. You will find complete instructions.

Thanks for the help! I forgot to put the black cap on the end of the motor shaft. It runs fine, but when I put the housing back on, it seams to be louder than without. Any thoughts? Thanks!

RE: Garage Door Opener

robaroo, sometimes loosening the screws that hold the cover on will lessen the noise. Chamberlain and Sears sell a noise kit but it is just some rubber pads with adhesive that eliminate the vibration. They go under the screws that hold the cover on. You could probably come up with some yourself.
