It's always been a little finicky, but tonight it stopped working. In the middle of going up as tonight, the door halted, leaving a gap between the door and the ground. I got out of the car, squeezed under the door and realized the motor was still running. My wife pushed the door opener a few more times, but the door wouldn't move despite the motor responding. I pulled the release on the door and opened it all the way. I realized parking the car in the garage would be a hassle, since I would have the open the door manually again. So I just closed the garage with the chain disengaged. The motor will start and stop in response to button pushes like it is supposed to - normally the first push starts it in one direction, the 2nd reverses the direction and the 3rd will stop the motor.

However, the chain has completely stopped moving (and by extension, so has the door). This causes the motor to run for an extensive period of time before it seems to timeout and give up. The chain and door connector assembly haven't budged since. I've not worked on garage doors before, but I have a degree in Computer/Electrical Engineering. I've never studied to be an electrician or anything, so I'm well aware there are a lot of things I don't know about this. But generally speaking, is this the type of thing I could potentially fix myself? Or is it more likely the whole unit is shot and I should just call a repairman up front? I know I have the manual around here somewhere, I'll keep looking for it and list exact part numbers if I find it. Update: I popped the sprocket protector off just like in the video form Steven's answer and the chain is still firmly attached. When the motor is running, you can clearly see the shaft and sprocket are not moving at all, not even jerking when starting or stopping, like something had locked up the shaft.

You should be able to easily see if the chain is off the sprocket. Try running the opener while you are up there too. If the chain has come off you will need to loosen the chain tension, place the chain back over the sprocket and tighten it to the correct tension. Your user manual should have details on how to perform this but usually there is a screw you adjust on the trolley that controls the tension. Make sure to disconnect your door from the trolley before you do this. Here's YouTube video that shows the process. I ended up having to have this replaced. I got a repairman out on a 'free housecall' who quoted me a price for the parts & labor. The price was less than a replacement, but the fellow warned me no one would warranty a repair on a 15 year old unit beyond 30 or 60 days. The unit originally had a 10 year warranty and was installed in 1999 (Craftsman garage door opener warranty page, for reference).

It's possible that the fellow really needed to sell a unit and was underselling the feasibility of the repair. bi fold door dressingBut I'll never know because I sprang for a replacement unit with a lifetime warranty through both the installation company and the manufacturer.garage doors winnipeg prices Thank you for your interest in this question.front door repair walnut creek Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).screen door repair melbourne fl

Intermittently, the car remotes will work. As suggested in some posts, I've tried pressing the lock button for a few seconds with no response. Any suggestions before I call the repair company?

did you check the floor sensors by the garage door to make sure they are aligned? Thanks for your response. The sensors at the bottom of the door show one with a yellow light and one is green. Should both be green? I tried to get the one with the yellow light to show green, but no luck. Thanks for any suggestions! Green and yellow are correct.Did you ever find a fix? My husband purchased a new control panel at Sears for about $22. Installation was simple and the opener works perfectly now. My sensor was loose and point out..and tighten and got fixed.. Depend on the type of opener you have. However, the best way to check to make sure you're not spending unnecessary money. There's a button to the right of the garage door opener (this is the one attached inside your garage), press the one to the right (the one that you lock the garage). You will notice the light on the opener will stop blinking (there's a steady green light). After that, check to see if this unlock the wireless device inside your vehicle.

unit is in lock mode-hold down the lock button for 5 seconds and it should go to steady green light and work correctly- no button on the side of wall mount light. This worked for me. My garage door was working fine but the light was blinking on the wall. The sensors were fine. It didn't work the first time, but after 2-3 times this worked and got rid of the annoying blinking!Had to do with the "learn" button on the motor, and pressing one remote, resulting in both car and remote working again and the blinking stopped. Thanks for your input. BTW I had a similar issue where none of the car remotes would work and there was a continuous green blink on in garage button. Turns out someone pressed the "lock" button as someone earlier suggested. Pressing it again took it out of lock mode. Hope that helps others in the future Thanks...that worked for me and the opener works fine again. This solved my issue. I didn't even know that I could lock it. Thanks so very much

I have tried just about everything done here, except replace control console. Tried the lock button, no change. Any other suggestions pls?That worked for me. I have my manual, and have not found any reference to solve that problem. Took 10 seconds after reading this. I didn't know about lock button and lost manual. Pushed the smaller button on wall switch which has a small picture of lock. The blinking green light went solid green. sweet, easy fix with holding down the lock button...it's been driving me nuts for a month!!!This worked for me also We were experiencing this exact problem: blinking green light on control (wall) switch and car controls no longer worked. I confirmed the sensors by garage door: one was green and the other yellow. Pressed lock switch on wall controller and held down for 5 seconds and now solid (no flashing) green light and car controllers work. THANKS TO ALL for helping me to solve the problem without maintenance call. What a life saver- worked great
