It’s Monday morning and you’re late for work – again.
You hit the wall switch to lift the door, and then… whirrr, bzzzz… bang! Your garage door is jammed!
Why does it hate you like this?
Well, your garage door doesn’t hate you, but it might feel a bit neglected.
These are the most common reasons why your door just got its jam on.
The good news? almost all of these causes can be fixed, quickly – by you.
Lack of Lubrication
If your garage door chain or track loses its lubrication, the door can get stuck.
This isn’t all that common these days with nylon rollers, but it’s still possible.
If you heard a high-pitch squealing before your door jammed, then you may have a lubrication issue. Try spraying standard machine oil onto the chain.
The problem may also be with one of your end bearings. If so, then you will need to replace one or both.
Door Off Track or Track Is Damaged
You can easily bend the aluminum garage door track by hitting it with the top of a tall SUV or truck, or perhaps something you might have put on top of or in your vehicle.
Ladders are also a common source of track damage. Check your tracks for deformation by looking down the track length-wise with a flashlight.
You may be able to bend the track back into shape using a rubber mallet. If not, then you will need to call a local garage door professional to replace the track.
Door Sensor Problems
Electric garage doors today use optical sensors to detect whether the door is closed/in place or not and to detect whether something or someone is under the door (for safety reasons). The sensor’s transmitter and receiver are located on opposite sides of your garage door, near the ground.
If your door won’t close, it is possible that something is covering one side of the sensor unit. Spider webs can also attract debris which, over time, can block a sensor.
Another common problem is a bent, deformed or off-center sensor. The sensor mounting bracket is probably made of aluminum and easily bent. It’s really easy to bend back, by hand.How To Fix A Jammed Garage Door by Reggie Williams
