View Full Version : Before I call for a repair, does anyone here know anything about garage doors?

My silly garage door isn't working properly. It won't go down unless you hold the button for the duration of its descent. (The little remotes in our cars won't work at all.)

We've cleaned the lenses and realigned the beam along the base and that will make it work for one or two times, then we're back to it rattling back up as soon as it starts.

Any suggestions?

DO NOT attempt any DIY repairs on automatic garage door openers!!

Seriously, some types have a tension spring in them that can actually kill you if let loose. You absolutely have to call a repairman, Perks!

What type is it? If it's just a Sears thing, check the chain track, it might be a simple case of either tightening the chain or loosening it. (You'll have to experiment.)

Also, maybe you need to grease or oil the door tracks. We have to lube our's occassionally or it won't go down.

Meerkat, not sure what kind of door openers you've seen. You could be correct, but I'm only familiar with the DIY door openers you can get over the counter at Sears and install yourself.

Is Ferret a farm animal?

It's a 'LiftMaster'. I've read up on it and all symptoms seem to be indicating a sensor problem. I makes sense, but I just can't seem to get our 'fix' to stay. Grrr. And it's pouring cold rain today, so I'm not all that keen to get soaked in fiddling with it.

I guess it's a good problem to have. Worse things have happened.

And after I offered help, too?

You're dead to me, Perks.

I just got an unbearable twinge in my left butt-cheek. Somewhere on Planet Earth, a ferret must be pouting.

But I'll bet his garage door works.

I greased my door and tightened the chain.

I agree with Meer...call a repair guy and get it done right.

This from someone whose leftside door has not been used for over a year because he finally got it locked in down position because it wouldn't close and the mechanism is crap.

Yes...I have to call one too. I put everything off.

how long have you been thinking about posting in this thread?

How old is it? It sounds like the motor is screwed up.

Oil the chain
There should be two adjustments on the motor control, an UP tension and a DOWN tension. increase the DOWN tension a quarter turn after you've oiled the chain. If it gets farther down but still stops, add more tension in quarter turn adjustments, until it closes.

The sensor works in conjunction with the tension if the tension is too low, no matter how perfect the sensors are aligned, the door will find a reason to stop.

Thanks guys! I'll give that a try. It's only four years old.

I second the comment above, the tension spring can indeed kill you.

It is the coil looking thingy that runs across the top of the garage door. Don't mess with that at all!

Yes, THAT will kill you, but I also don't think THAT is her problem.

I say, screw it all. Dig up your garage floor and turn your garage into a garden/patio.

A rose garden and a barbeque pit would be lovely.

Try a new battery. Cray's available.

Kick it.

Seriously, I have a Liftmaster, too. It does sound like a sensor problem. It could be the sensors are not staying aligned because the metal is not staying bent (that make sense?). Bend them farther, so they go past being aligned, then bend them back.

If that fails invite Rob over and kick him. We'd all appreciate that.

There should be two adjustments on the motor control, an UP tension and a DOWN tension. increase the DOWN tension a quarter turn after you've oiled the chain. If it gets farther down but still stops, add more tension in quarter turn adjustments, until it closes.

The sensor works in conjunction with the tension if the tension is too low, no matter how perfect the sensors are aligned, the door will find a reason to stop.

Is it just stopping? Or is it stopping and then opening back up. (Yeah, been down this road.)

If the sensor senses a "blocking of the stream" of light. It stops and goes back up. Whether that's real, or a faulty sensor depends on how many pets or how much crap you have in front of the door.

If the system senses a blockage above the sensor lens, it stops the door closing (or opening) process. This is where tension comes in. Too much tension, it stops. Cold metal doesn't like to move. Every winter, I have to adjust this, with the tension screw settings. Adjust slowly, test in quarter turns, as described above.

Also might want to remove the cover and look for plastic shavings in the casing. Those fiber plastic gears are (IMHO) designed to wear out. Make sure the power is off to the unit. I do not recommend repairs to the unit. (I've done it once, and then got to do it again.) Replace the silly thing.

At what point "Do it Yourself" stops and common sense takes over, is kind of up to you and your free time. :)

ETA: Almost forgot. This does not preclude the kicking Rob step.

How the heck is she gonna kick it, Rob? It's mounted to the ceiling. Sheesh.

Hit it with a hammer, Perks.

I don't know anything about garage door openers, but kicking Rob, then hitting him with a hammer seems like a good idea to me.

Sounds like an issue I had once. Try greasing the wheels of your door. I don't know if you have cold weather, but if the wheels are a little sticky/rusty, perhaps greasing it might help. A little tension from the wheels not turning could cause the safety machinery to think it's hit something and retract.

If the door retracts, see where the door stops. Maybe the track got hit or nudged and became misaligned. When the wheels hit that spot, there's tension, and again the door thinks it's hit something. Maybe an adjustment of that track could fix it.

Robeaie had the same problem I did too. The beam nut loosened and that was a problem too.

Good luck.

Hope you get it fixed very soon, Perks. Don't have any advice for you, unfortunately, but here's :Cake: to help you in the meantime. :D

Try greasing the wheels of your door.

Important note: grease the wheels, not the track. If your track wasn't greased when it was installed, it's not supposed to be greased.

When I was out at sea once, a helpful neighbor greased our track when my wife had a garage door problem. We tried to clean off the grease many times, but we could never remove all of it. So leaves, etc. got stuck onto the track for years.

Don't grease the track!

Well, I'm down to boots and hammers. Or there's always the Mossberg twelve gauge.

That's an interesting euphemism for it...

Had an issue many years ago when we had to increase the force (tension?) on the opener. A few years ago, had to replace the whole unit.

Just before Thanksgiving, one of our torsion springs broke. That was fun...
And yes, I knew enough to call and have a professional out for that part.

And then back out that evening after they screwed it up from earlier in the day... :)
