My garage door would stop by itself. And when i push the remote control, it would comtinue to close. Before, if i push the remote button twice, the door would reverse in the direction it was going. So it is probaly not the remote. Any ideas?? I read about that from the other posts. I'll try that first and see if that fixes the problem. And FYI, I only bought the place brand new about 9 months ago.
And got the following answer:
The opener stopping is a sign of the motor being overloaded / safety switches stopping the door. This may be from the door itself being out of adjustment / broke OR the opener needing adjustment. You should NOT "just" adjust the opener!! First, pull the safety disconnect rope on the opener. This will disconnect the opener from the door. Then check the door. It should roll up & down smoothly. It should NOT be too heavy or so light the it pulls itself up. It should stay where ever you stop moving it. It rolling up or down, by it's self means it's not adjusted right. You could have a broken counterweight spring. Garage doors are HEAVY. It may be as little as a 100 lbs or as much as 300-400 lbs. The counter weight springs allow the door to be feather weight. Some have one, others have two springs. A broken spring WILL burn up the door opener. The hinges / rollers need to be loose (lubricated). The rollers to track does NOT need to be lubricated. The roller should ROLL in the track. They do NOT slide in the track. ( Do you grease your car tires, to get them to roll better????!!) If you have solid (wood) weather stripping, does the door have a slight gap, when you push the door IN, when it's down? If the door is tight against solid weather stripping, it will could have too much friction (door out of adjustment / hinges / rollers worn). If you have any type of weatherstripping with a flexible (rubber) edge, it should be it good condition. Rips could cause excessive friction. Stick a butter knife in between the door & weatherstripping and pull it out a bit. You should a good bit of gap between the door & the solid part of the weather stripping. If the door seems OK, check the opener. It should still be disconnected. For any kind, other than a gear drive ( chain / cable, both visible on the outer sides of the track), there is a two piece "trolley". One part is attached to the opener, the other to the door. When you hit the button, the trolley should run from one end to the other, then stop. If it doesn't make it all the way, you have a problem with the opener. It should run back & forth just fine. If you have a gear drive (you can tell a gear drive by looking straight up, into the track, you will see a long gear or screw from one end, to the other), the opener should work, as above, but it may take a minute, before it shuts off. It will have a one piece trolley. It uses the door trolley to trip the off (limit) switches, no door, it will shut off after a time limit. Most openers have safety switches on them. These are two photo electric "eyes" down low, near the floor. There is a "sender" & "receiver". The sender light should always be on, the receiver light will be off, if something is blocking the door. The receiver should be pointing either east or north, the sun can burn them up. If the receiver does not pick up the light from the sender, the opener will NOT go down. It thinks you or your kid is under the door. Most eyes should have LED lights on them. If one is off, they are out of whack. You need to turn one or both, until both LED's are on. If you can not get both on or if both are off, you have bad wiring / photo eyes / opener control circuit board. Spider cobwebs / cobwebs with leaves, etc, can be an issue. Now, if all seems well, adjust the opener. Some have one adjustment, some two. ALL have separate adjustments for up & down. For two adjustments, there is a "force" with controls how HARD it pushes before stopping / reversing. The other is a "limit", which is how FAR it pushes, before stopping. You should ALWAYS adjust the limit, before the force. This is to keep you kids hand from being crushed under the door. (also, the track should NOT bow way up, just a little). A 2 x 4 under the door should trip it back up.
