Are you dealing with a garage door chain that is loosened and rubbing against the rail? This is among the most frequently encountered issues for garage doors that are operated by an opener with a chain drive. The chains of garage doors get slack due to the vibrations generated by the motor, as well as the weight of the door.

The tightening of the chain is, therefore, an essential part of the garage door maintenance Atlas TX routine. A chain that is loose isn’t only noisy, but it also causes your opener to perform more work, which makes the entire process less effective. It may cause your door to overtake the track.

 A technician can adjust the chain of your garage door in a scheduled maintenance appointment; however, garage door repair is something you can perform yourself when you’re adept. Here are some helpful tips on how to accomplish this from the experts in garage doors.

How to tighten the garage door chain

The tightening of your garage door’s chain is as simple as turning the proper nuts. The one you’re seeking is connected to a bolt that is located in the area where the carriage or trolley connects with the track.

The trolley is responsible for pulling or pushing the opener’s arm along the chain to shut and open your garage doors. It usually has a piece of rope hanging from it which can be used to detach and then re-engage the opener.

Step 1: Disconnect the Power Supply and turn off the Opener

Before you begin working, you must be aware of precautions to ensure your safety. First, ensure your garage is locked. After that, you must disconnect the power source. If you’re not sure how to do that, remember that the majority of openers plug into an outlet in the ceiling. It is also possible to refer to your opener manual.

The power supply must be disconnected. This is crucial. It’s likely that you’ll be sitting on a stepladder whilst playing using the trolley. You could be in grave danger when the garage suddenly started opening as you were working.

Lastly, remove the garage door to the opener. If you own an opener with a square rail and you want to pull it down, then pull on the red release rope. If you have a T rail opener then pull the manual release rope downwards before pulling it back towards the opener.

Step 2: Put the Adjustment Bolt in the right place

Get on an inclined ladder and look over the trolley. There’s likely to be one bolt on the side. It’s a threaded fastener between five and seven inches long. There are two screws. One is used to lock, and the other is used to adjust. The locking nut, as well as the adjustment nut, are separated from one another with a divider, and the lock nut is closer to an opener. Tightening the adjustment nut increases tension on the chain of the garage door.

Step 3: Loosen the Locking Nut and Tighten the Adjustment Nut

With an adjustable wrench or half-inch wrench, begin by loosening up the lock nut a bit. Then, tighten the adjustment nut and then increase the tension on the chain. The chain is to be tightened to the point that it is in the middle, approximately a quarter-inch higher than the rail in the case of a square rail, and about a half-inch higher than the rail for a T-rail. It’s essential to not tighten the chain too much, as it can result in the chain rollers beginning to wear down prematurely. Actually, in general, it’s preferential to keep the chain somewhat loose instead of tight.

After you’ve adjusted your chain to the correct tension then tighten your locking bolt. It is recommended to use two wrenches for this, one for holding the adjustment nut while the other is used to turn on the lock nut.

Step 4: Reconnect the Power and then re-engage the Opener

Connect your opener to then reattach it by pulling the release rope manually back towards your opener, until it snaps into position, or simply the garage door by pressing the wall button. This will trigger the trolley to be able to snap back into position automatically. If you engage the opener again, you might be able to see that the chain begins to relax a little. This is normal. The chain will be able to regain its tension once you are in an open position.

Step 5: Run a Test

The garage should be closed and opened several times to ensure your issue is solved. Should the chain hit the rails, you can tighten the adjustment screw a bit more.

It is not necessary to be concerned about the tension of your chain for at least one year. If your chain tends to go in a slack state, it’s an indication that the opener needs replacing. Chains, as well as openers, are susceptible to wear and wear and tear.
