7 Reasons Why Garage Doors Will Not Open
by Daniel Tam on Nov 14, 2017
Garage doors can play all sorts of tricks on us. They might open with some difficulty or fail to open all the way. Other times, they might go up and come back down before they open up again. All such problems need quick actions and professional troubleshooting and garage door repair. But our headache gets worst when the overhead door won't open at all. Find out which the main reasons for such a problem are and what you can do about it.
Broken garage door springs
You will hear the garage door opener humming but there will be no door movement. It will stay on the ground and will only come up three-four inches if you have a very powerful opener. This is a clear sign that the garage door torsion spring is broken. You notice that we don't talk about garage door springs in general. If your door utilizes extension springs, they won't break together. And so the door will try to open up but it will be sagging to the side. Naturally, when it comes to broken springs, the need for their replacement is imminent.
Damaged garage door motor
Your garage door motor won't live forever. At some point, it might get damaged, ruined, or worn. In this case, it will definitely need replacement. Another problem with the motor is the power. The wires, which travel all the way from the socket and sensors, to the motor's terminals might be damaged. Naturally, any problem with the motor will bring the automatic operation of the door to a halt. What you can do is disengage the opener and move the door manually taken that the springs are not broken.
Dead garage door remote battery
Sometimes, problems are as simple as replacing the battery of the garage door remote clicker. So if you click the remote but the door won't open, check the clicker's battery first. A clear evidence of a remote control problem is when the opener is activated by the wall button. In any case, try replacing the battery. If the door still doesn't open, you need to call in a pro.
No power in the garage
If the opener makes no sound whatsoever, chances are there is no power in the garage or house. In this case, you need to call an electrician. But if there is power in the garage and the opener is connected with no apparent motor or wire problems, check the release cord. If it was accidentally pulled, the opener is disengaged.
The garage door tracks are dirty
The garage door tracks get very dirty. Sometimes, tree branches and rocks land on tracks and thus keep the rollers from sliding. Although it will take a rather solid object to keep the garage door rollers from moving, it happens. The door won't open if the rollers find obstructions. So one of the first things to check is the tracks. If they are dirty, remove the debris or anything blocking the movement of the rollers.
Locked garage door
Most garage doors can be locked manually or automatically. So one more thing to check if the overhead garage door won't move up is the lock or lock setting. It might have been accidentally set to the lock mode keeping the door from moving.
The sensitivity is off
When you install garage door openers, you also adjust the sensitivity settings. The opener actually senses the door and its weight in order to bring it to the right opening and closing position. When the sensitivity is set either too high or low, the opener gets confused and since it won't sense the door's weight, it won't open it either.
