Craftsman 1/2 HP Garage Door Opener won't Close
Comments (2)Ok.. Just try running the garage door by pushing the button and see if it catches the latch just fine. It will probably be just fine.... What your friend was trying to tell you to do is to grab the garage door and manually open or close it to catch the latch back onto the chain. You don't want to pull on the red cord when you are doing this - just grab the bottom of the door and either open it or close it to catch the latch. You REALLY don't want to do this with all your strength - or you might break something in the garage door latch.. It's usually harder to open and close the door - so it takes some strength to open it up without the help of the motor... but you want to go slowly when it's hooking the latch back up or you might break that part. Here's what is going on.... The Red pull handle thingey has a spring loaded latch inside it... kinda like how a door knob works. That latch grabs onto the hole on a plate connected to the door opener chain - and the garage door goes up and down when the motor runs. (It holds together like how a door latch holds a door closed) When you pull the string - you just pull the latch out of the hole in the metal plate connected to the chain.. like how turning a door knob lets you open a door.... and you can manually pull the garage door go up and down without the motor moving the chain. Does this make sense......See MoreCraftsman 1/2 HP Garage Door Opener SIMILAR Problem
Comments (11)Well, rather than a repair, I just moved into our house (3 years old) and the third car opener has never worked right. It initially would go up, but not down, and didn't stop at the top, it just jammed and vibrated against the opener unit. I opened it up to find that somehow the open adjustment stop was bent and the locator just went right by it and kept trying to go up. I righted that situation by bending the stop back and setting the open travel adjustment properly. So now, it will open, and when hitting the stop, does stop. But, it will not close. I can manually close it by removing the belt from the motor and getting everything set at the bottom, then push the button and it opens again and stops properly at the top. Holding down the button does no good, and I can confirm the photo sensors are aligned properly because if I block them, the opener lights come on. It just seems to me that whatever switch exists to tell the opener it is at the top and needs to reverse direction has failed, but I have no idea what that is or how to fix it. I did find the start capacitor you guys were talking about (big blue guy, 4 wires, two red, two blue). My terminals are top and bottom, with connections on each side of it. The reds are on the bottom, and the blues on top. My opener is model 139.53954. Thanks for helping....See MoreCraftsman 1/2 HP Garage Door Opener - Only one works!
Comments (153)Hi everyone, I know i sound like a tape recorder but my craftsman 1/2 hp has been working fine for 3 yrs. Not sure what happened to the remotes, but they stopped working. I first tried replacing the batteries but after that didnt work i went out and brought two brand new up to date chamberlain klik3u universal garage remotes. Retail 40 bucks per. They say in the manual they are compatible to my garage opener which was manufactured in 1997. They wont program as well. My garage opens and closes fine. I guess im here to find out if anyone has any other trouble shooting facts to program because the "press the red button like a door bell, hit the button you want programmed" basics isnt working for me. I called chamberlain about the remotes and they basically told me go jump in a lake, all our remotes program fast and easy!!! I need help ppl. Plzzzzz...See Morecraftsman 1/2 hp garage door opener
Comments (1)You didn't reset any codes. There is no way for you to do that. If the previous owner still has an opener he can open your door. The only way you can prevent that is to buy new remotes, erase the memory of the receiver by holding the learn button in for 6 seconds and then program the new remotes. If you program the old remotes you are back to square one. There are a couple things that can cause the door to open by itself. One is if the installer used uninsulated staples when he ran the wire from the wall button to the opener. They sometimes cut through the insulation due to vibration and cause the opener to open or close. The other reason is the 'down limit' adjustment can be off just enough to allow the door to hit the floor and the safety circuit senses the door has run into something and it will reverse it to the open position. Both possibilities can be intermittent....See Morejairadhey
