I have a standard 2 car garage with a metal door and an Overhead Door “Legacy” 1/2 HP opener that is approx 4.5 years old. Recently it has started only opening the door part way. Sometimes it stops opening when the door is about 12” open, sometimes it stops at the halfway point and sometimes around the 5/8 open point. If I press the button again I can get it to open all the way but I usually have to do it 2-3 times to get the door fully open. It never has trouble closing the door.

I’ve tried adjusting the “open force” dial on the back of the opener and currently have it all the way to the maximum setting but that hasn’t helped. I’ve also disconnected the door from the opener and opened and closed it manually. It seems to slide freely without binding or getting caught.

I tried disconnecting the “laser beam” from the opener to see if that helped, but as soon as I disconnected it the opener will only work if I hold the button down.

I’ve also tried disconnecting the wall pushbutton and manually shorting the open/close jumper to trigger the door to see if there is a short in the wire to the button, but that didn’t help the problem.

I downloaded the manual and looked at the laser beam troubleshooting section and according to the manual the system is working properly (the lights on the sender and receiver units are both on solid).

One other thing I noticed is that when the opener is operating, the light (the one that’s supposed to light up the garage so you can see to get in/out of the car) flickers on and off rapidly instead of turning on and staying on. This seemed to start around the same time the trouble started so I’m not sure if it is related.

What else can I try? If I need a new opener is it as simple as replacing the opener itself or do I have to replace the guide rails and everything?

I don’t know what the problem is with your door but I have an 18 ft wood door that is well adjusted but heavy nevertheless. I’ve been through three openers. I finally found one that I love and it’s lasting. It’s made by sommers and comes from Germany and has a lifetime warranty.

It’s a design that’s so simple and works so well it almost makes regular openers look design foolish. You mount an aluminum U channel track on the ceiling. In the track a standard bike like chain is stretched in the channel. Very tight. A small DC motor that is geared down travels up and down the chain. The door is attached to the motor. The thing looks like a cog locomotive on a track. To set the up and down limits you just place a stop on the rail. When it hits the top it pushes in a switch that stops the motor. You can set it anyplace you want.

Except for the gear connecting with the chain that turns to move it back and forth there are no moving parts. I got mine a Lowe’s.

It still has the box at the end of the rail but it’s just for lights and power supply. The harmles DC current runs in the track. Much like a model train.

Garage doors are something I pay the pros to work on. I’m certainly not a pro but I had a similar problem. I would bet that you 4.5 year old opener won’t have the same problem.

Here was my problem, I had a trip switch on the track. When the door rose up and flipped the switch, the door stopped. The switch came loose and follow the door down on occasion. When it did that, the door would stop at the new switch location. The only thing is, it would always stop at the new switch location.

I would guess that the technician has to program in the automatic stop points these days because I no longer have that trip switch.

I got a new one. A few years later, the gear started slipping because the cheap plastice bushing wasn’t holding it in place correctly. The gear was wobbling and didn’t catch all the time. When the door thought it was at the top, it stopped. I had to lower it again, and raise it again and sometimes it would open all the way. I got variable results. This one could be your problem.

Best of luck to you! I hope your issues are easy to fix without draining your wallet.
