F&I Genie Garage Door Opener 1/2 hp model H6000-2K Screw Drive
Comments (2)From your description it sounds like when you came back to close the door after mowing something was blocking the safety beam or perhaps you bent the safety beam mount with the mower?? Anyway pulling the cord only disengages the door from the Genie screw and not from power etc. Stopping after 5 minutes is probably a heat sensor shutting the motor off. I would call the installer back and try to have a reasonable discussion with him. There probably isn't much wrong if anything. The manual is a good source of information but not very interesting reading....See MoreCraftsman 1/2HP Garage Door Opener won't Open
Comments (4)If it is stuck in the open position you will most likely find the trolley is jammed against the bolt just in front of the motor unit. You will need to loosen the chain enough to release the tension and then run the opener until the door closes. While the door is closed locate the 'up limit' on the side of the motor unit and turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Tighten the chain....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 MoreRaynor 1/2 HP Garage Door Opener won't work
Comments (2)I figured it out. Problem with adjusting the limit switches was due to a missing pin on a gear that is on the main motor shaft that turns another gear that moves a plastic screw that hits the up and down limit switches. In other words, the internal up/down limit switches were not getting consistant feedback of the garage door position. Nothing that a twisty tie from a garbage bag couldn't fix. So that problem was fixed. The garage door now moves and it now moves up and down without whacking the header going down and the stop limit bolt (protecting the GDO motor unit) on the way up. I knew I was wasting time when the manual says a single rotation on either screw would result in a 2 inch travel change. and nothing I did was consistant. It either hit the bolt or header or it would just HUM and not do anything. I think the original problem of why the belt's tention spring/bolt came undone was due to excessive vibration due to non-sufficient belt tension. As soon as i got the garage door operational, I noticed it was hecka jerky initially going up or initially going down. Mid-travel was smoother. By tightening the nut (collapsing the tension spring) to the 1.25 inches specified in the owners manual seemed to make the garage door much smoother. When I have the time, I'll adjust the force screws down. I think I have them maxxed out right now. I'll also test the safety/reversing feature. For now, it open and closes smoothly. I'm happy. So, while the owners manual didn't tell me to open the thing up, common sense told me to. Also, this unit has a diagnostic feature. When you press the LEARN button, it will light up the diagnostic light and blink. 5 blinks told me the motor was overheated or the RPM sensor wasn't happy. No mention of what the RPM sensor was. I'm assuming something was stuck. Anyways, adjusting the limit switches got it moving and once I cracked open the motor housing case and saw the limit switches in action and saw how misaligned they were, it was a pretty easy fix. Glad I disconnected the door so I could cycle the belt for testing without crashing the door. that made way too much noise at 10PM tonight. Once again, thanks for your help and I hope something in this helps someone....See Moredeatherage
