A belt driven garage door opener can be a bit quieter during operation. Consider this when making the choice of what opener to buy.

The weight of a garage door is supported by the door springs, cables, and pulleys, not the opener. If you can’t raise and lower the door normally by hand, do not install the opener until the door is repaired. Remove all ropes or cords attached to the garage door so you won’t get tangled in them during installation. Deactivate or remove all existing garage door locks, so they won’t accidentally engage and either damage the opener or cause personal injury.

If you need to install permanent electrical wiring, always disconnect the power at the main breaker box before attempting to wire connections. Always connect the power cord of the garage door opener to a properly grounded outlet to avoid electrical shock.

First put the rail together. This should come in several pieces that fit easily together. [2] X Research source Attach them together as directed in your installation instructions. Then you will need to slide the carriage (also known as a trolley) over the rail. This is the piece of the opener that will move along the rail, pulling the door open. Attach the rail to the motor compartment. This is the largest piece of the opener and it will be positioned furthest from the garage door. Install the pulley at end of rail, opposite the motor compartment. Then feed the belt or chain through the end of the rail, around the pulley, then around the other end (at the motor). Finally you will attach the end of the belt or chain to the carriage. The end of the chain or belt should have a screw attached to it, so that you can easily attach it to the carriage. This screw will also allow you to adjust the tension of the chain or belt. [3] X Research source

No matter what the size and spacing of the blocking is, be sure that you are attaching it to joists (solid wood) in the ceiling, not just to sheetrock.

If your garage door opener did not come with this bracket you will need to consult the instructions to determine what type of bracket you will need. [4] X Research source

Many garage door openers use the light to signal programming changes that are occurring. Be sure to install the lightbulb in your opener so that you can program your garage door successfully.

Be sure to follow the instructions and wiring diagram included with your opener.

Also install and program any other optional equipment, such as a keypad for opening the door on the exterior of your garage or remote openers.

Some garage door openers can be quite loud under normal working conditions, so don’t assume that just because it’s a bit loud that it is not installed properly.
