Garage door opener seizing - causes?

My automatic garage door opener has begun to stop after moving a couple of feet, either up or down; the sensor is not obstructed - I suspect cold weather is freezing the spring axle on the door, but oiling it didn’t help.

It’s a chain drive; I took it apart and found that the sprocket bearing failed and the drive gear worn down (it’s plastic). Fortunately, I found that these parts are easily located on eBay - thanks for the advice!

Answer:

Those are all good answers and I am glad you discovered the bearing problem. One caution, generally garage doors are “assisted” up by spring tension. This is what allows you to open it with little effort in the absence of a opener. It also makes it possible for openers to be designed with little horsepower. There are two types of springs used. Extension springs are mounted along the track parallel to the ceiling on both sides. A torsion spring is mounted along the wall above the door and parallel to the top of it. If you have extension springs, they may have lost their strength causing more tension “lift” on one side than the other this will get the door in a bind and in a chain reaction parts of the opener may fail. If you have a torsion spring, they can get out of adjustment causing the same chain of events. “CAUTION” most torsion springs require a qualified professional for adjustment (They can kill a person and have). Some of the newer ones can be adjusted by anyone using a drill.

Garage Door Opener… Where’s The Remote Code?

I have a very old Genie garage door opener, Model 400. It’s very old… probably at least 20 years or more. The unit works just fine but I have no remote. I bought a universal remote but can’t find the code to program the remote. Where is the code located on the unit itself?

I have looked on the outside of the unit, except for the very top which is blocked by the top of the garage. Anyone know where the code is before I try to take it all apart looking?

I rent my home so theres no sense in buying a new one. I need to find a way to make this one work… hopefully

Thanks for all your help!

By the way, the push button inside the garage opens and closes the door properly. Just need the remote to work!

Answer:

open the back or side compartment
there you will find a group of pins or little levers sometimes they have # s under them or letters such as a then b then a then b and on and on and on they go a =1 b=2 so on and so on …good luck

That is correct normal a green or red little board with dip switches on it.
The remote should contain a board similiar inside it.
Set the codes the same and remote should then work.
It no dip switch, check controll panel for buttons and see if this is way activation works, this is how Genie models operate in the newer models.
You push button on front panel beneath Light cover, when it lights you then hold button on remote unit until the light on control panel blinks and then goes solid.

Garage door opener?

 I just brought a new house with a garage,but it can not open. So now I am shopping for a new one, but I dont know which one suitable for me.

What should we consider when buying a garage door?
Screw vs chain drive?
Speed?
HP?
Which brand names are good and which are junk.
Please help

Answer:

ok this is the easist. Stay away from genie, overhead, and wayne dalton. Genies are junk and are made by overhead, and wayne dalton is having problems with some of their openers. The best to go with is a Liftmaster. It has a one peice rail and very good. If you do not go with liftmaster go with either a chamberlain or a craftsman. Now as far as chain or screw I’d say neither. Go with a belt. Belt drives are much quieter and work just as well. On Liftmaster belts they have a lifetime warranty on belt and motor. Belt drive is the only way to go. Now as far as HP, a half horse should be enough. The springs on a door do all the work. If a door is properly balance you should be able to lift it by hand with minimal effort. If you cant you need to get door fixed. If a door is in balance a 1/4 horse would be more than enough.

How to slove my garage door problem?

My garage door is like 11 years old almost. It just dawn on me that I use to just press the remote or the button inside the garage once and the door would either open or close automatically. With one push it will open but now I have to hold the button until it closes otherwise it just dances up and down. What is up with that?

Answer:

Have you ever oiled the spring or the joints? If not, get some WD40 and spray it on them. You should do this abotu 2 times a year. Could just be too much pressure on your spring. The other thing is that if your door has one of those electronic eye kid safety systems on it, it might just be dirty or slightly out of alignment.

If neither of those work, Id consider calling out a garage door service company to get a “tune up”.

My garage runs but doesnt pick up the door…

My motor of the garage door runs but the door remains stationary.

What is the problem and what is causing it? 

We can pick up the door by hand but cannot use the remote.

 Answer:

Oh.. I know exactly what the problem is.. I have that same problem from time to time.. maybe once every 2 years.. The problem is that you have to get a new SPRING.. It is that long spring that is ON the garage door.. It is broken and if you check carefully, you will see where it is no longer ONE long piece but is broken into two….A garage door man would have to do that for you.

the gears are plastic inside the box and will wear out. they can be replaced

Garage door doesn’t always go down?

Our garage door will start to go down, and then will start to go back up. The spot that it stops is random, and it seems worse in colder weather. (We didn’t have any problems until it got cold- when we had another heat wave, it worked). It’s not the sensors at the bottom, we’ve checked those.

I found something on line about the tension, but it shows the springs on either side of the garage. Ours does not have the spring on either side. There seems to be just 1 spring, over the top of the door.

It’s a craftsman, if that helps.

Answer:

First,, unhook the door from the operator, and run it by hand, you should be able to stop the door at any height and it should stay there, if it is balanced properly. If it drops to the ground then you need to add winds to the spring until it stays where you stop it. After you get the door lubed, spray the spring at the top of the door and the rollers and the bearings that the shaft goes thru with a spray lube, ( do not put grease in the tracks)…. after the door is running properly, thennn start looking at the operator, if it just stops at random places, take a look at the down sensativity screw on the back of the operator,, it should be approximatly the 4 o’clock position to start with, that should be more than enough pressure to close the door then, if not,slowly bump up to 5 and then 6 if necessary. If it was your saftey eyes causeing the problems on your sears operator, the light bulb on the front of the operator would be blinking off and on a few times, let me know what happens… Good luck..

I have question about the arage door spring?

What is the safest easiest way to replace the garage door spring. The kind that is above the garage door. Its a .250 (I think) spring.

I told my husband call Lowes and they said they aren’t allowed to sell the torsion springs.

They do sell extension springs but not torsion springs.

The spring is broken so theres no tension in it.

Answer:

Be safe and have a pro come out and do it.If you have to much tension on it you can get badly hurt..

Because torsion springs are very dangerous to install. You have to know what you are doing. If you’ve never done it before, hire a professional. I’ve done it but I have had a lot of experience in maintenance and even then I was very nervous, but careful. If you lose you grip while tightening them you could get hurt badly. There has to be just enough tension to assist in opening the door and keeping it up without falling from it’s own weight.

Where to buy the door opener for my garage door?

I have an older Sears garage door, lost the garage door openers. Can I buy a generic one and program it?

Answer:

The best thing to do with that is get the model number of the opener and google it.

Now if you see something about Security+ it means you garage has rolling code. If that is true, you will need to buy one that has the same freq. If it is, there will be a button up on the door motor, mine is orange. You will need to press that button on the motor and the button on the remote to tell the garage door to accept it. They have some nice options, even key chain remotes for like $25.

Now you said it was older, so it may not have that. If there is a series of dip switches on the motor you will need to set the same dipswitchs on the remote. Again you will need to buy the right one for the door opener.
