Inspect the Garage Door Chain

Before you attempt to do a garage door chain repair, you need to know the underlying problems.

To do this, make sure to follow the steps below:

  1. Open and close the door several times to observe the mechanism. If the door gets stuck during the operation, the problem could be the chain drive or the opener motor.
  2. To narrow down the possible problems, close the door and unplug the motor.
  3. Inspect the chain if there are visible signs of corrosion.
  4. Then, check the opener’s carriage assembly and inspect if the nuts and bolts are in good condition.
  5. Check the motor wiring and make sure it’s providing power to the garage door’s operation.

If you have narrowed down that the chain is the problem, try the different ways on how to fix a broken garage door opener chain, depending on the condition.

Ways to Fix a Garage Door Opener Chain

A broken garage door opener chain can stem from the following reasons. The following will help you to fix it according to different conditions.

Rusty Chain

Once you see rust and dirt on the chain, it can cause friction in the overhead door’s movement. To prevent this, follow the steps below:

  1. Apply a lubricant to smoothen out the corrosion. Pour oil on a towel and wipe it to the chain.
  2. If the chain is heavily corroded, detach the chain from the assembly. Then, soak it in a lubricant for a few hours.
  3. After soaking it in a lubricant, wipe out the excess with a towel.

Loose chains

Loose chains can cause noise to the operation of your garage door.

It also makes the movement less efficient because it forces the opener to do the work. It can result in your door jumping off the track as well.

Here are the steps to tighten it:

  1. Close the door using the opener.
  2. Unplug the power and disengage the opener from the door. To disengage, drag the red manual release rope down using a square rail opener. If you want to use a T-rail opener, pull the release rope down and back to the opener.
  3. The nuts and the threaded shaft are responsible for the chain tension adjustment. The adjustment nuts can be found on the left side of the rail when you are inside the garage.
  4. Loosen the nut closest to the overhead door until the chain runs below the rail’s base.
  5. Slightly release the inner nut to tighten the chain.
  6. To add the chain’s tension, secure the outer nut (nut closest to the overhead door) tightly. Once you rotate the outer nut, the chain will rise slowly.
  7. When the chain is approximately ¼ inches for square rail or ½ inches for T-rail above the rail’s base, tighten the inner nut to secure. The chain is finally tightened.
