guys hopefully someone has a idea.

yesterday after getting back from the lake the electric garage door would only go up about 5-6 inches then stops. hit the remote again and it goes down.

have to assist to get the door to open fully.

the safety sensors seem to be aligned.

thanks for your help.

mine has done that before. I just lubed the rollers, and chain or screw, (which ever you have) and should work.

Belt drive, chain drive, screw drive, or direct drive??

The safety beams only affect downward travel.

Depending on style I'll throw some ideas...

Misaligned tracks
Resistance on lift control setting too low
Broken spring
Spring wound too loose
Broken wheel/roller
Un-coiled cable
Old/weak motor

I've seen the chains loosen/stretch and the links themselves bind up on the track. All it takes is one good "hit" and the opener will stop on limit.

Same goes for the belt drives.

Mine did the same thing a while back, turned out there are limit switch screws on the back of my operator that had to be adjusted. After I did that, everthing has worked fine since...

Mine did the same thing. Turned out to be a broken spring and mis-aligned track.

Agreed, the only type of garage door spring I will mess with is the coil springs with the pulley on the end, of course if that broke it'd be easy to replace, those torsion style ones scare me senseless.

Check all the rollers. Mine was doing the same thing. It turned out that one of the wheels had worn out and broken off. When it hit the joint in the track it wouldn't go any further.

If there is a next time, Home Depot and Lowes has replacement springs. Most springs now are suppose to be color coded per weight/lift catagory, and I bought a pair about 6 years ago for around $19 ea. and it took about 5 minutes to replace them.

My garage door man told me to do that and to also replace both springs, not just the one that broke. He also showed me how to adjust the track, but it is done without the springs attached, so you can feel any binding in the rollers and track that the springs would normally cover up from the help they provide.
Also, it they are not already installed you need steel safety cables inside the springs, so if one breaks, they won't go flying thru the air and hurt someone or damage something. I had one break several years ago and I had used ski rope as a safety cable, and it held the spring, but it hit the vertical angle bracket hanging from the joist for the track and bent it all to pieces. I was upstairs when it broke in the basement over the boat and I thought someone had run into the house with a car or something.

I just put my own garage door in the new garage (see garage thd. still unfinished!), but the spring thing was a little scary. It takes a lot of force, but I probably could have used a better tool than an extension that was only 12" long!

Last time I posted a garage door question, Gene Doobies was in the middle of his rant and almost blew a gasket...maybe your post will cause Gene to quit lurking.

I was told by a garage door installer/adjuster that you should regularly lubricate your spring with a silicon spray. He can always tell when people don't because they get surface rust on them. Use a decent amount of silicon lubricant spray on your springs, in your tracks, and on the rollers.
