Does the trolley carriage on your garage door move yet the door refuses to budge? Chances are, you’ve got a broken trolley carriage. For most garage door openers, you can get a new trolley carriage for about $25 to $40, depending on the model. It’s a fairly easy part to fix. All you need are some simple household tools and a few garage door parts. A repair for a garage door trolley typically takes less than 30 minutes.
Preparing the Garage Door for Repair
First, position the door in a down position. This is very important before you disengage the door. Otherwise, it could come crashing down, which can be very dangerous. Next, pull the emergency ripcord, generally a red cord connected to the opener carriage. This is what connects the opener to the trolley carriage. It will let you manually close and open the door. Don’t worry. Reinstalling it is easy. Simply raise the door with your automatic opener, and it will automatically reconnect.
Next, pull the emergency release toward the door. This will disconnect the door from the motor.
To start, pull the old trolley carriage off, clamping the chain to the rail. This way, the chain remains on the sprocket, which will save you a lot of time later. Once you’ve secured the chain, separate both sides from the trolley. Disconnect the rail from the header, moving the rail to the side. Remove the old trolley and connect the new one. Reattach the chain. Adjust the tension. Replace the trolley on the belt drive, a fairly easy job.

Troubleshooting Garage Door Opener Repair
About 9 times out of 10, a garage door opener is very easy to fix. Sometimes it’s just a matter of changing the batteries in your remote or fixing a fuse in the fuse box.
If the garage door doesn’t budge at all, it’s probably a power issue. Start by replacing the batteries in your remote. Next check to see if the opener has become unplugged.
If there are other lights in the garage or house not working, it’s probably a blown fuse. Check the fuse box and see if any of the switches have been flipped.
You should also try to move closer to the door. It may be possible that your antenna is out of range. Check the antenna to see if it is damaged.
You might need to reset the programming on your opener, remote and keypad. Consult your operating manual or look online for specific instructions for your opener. Each model is different.
