How To Replace a Garage Door Opener in 6 Steps

A professional spends his day replacing garage door opener units around town.

Is your garage door opener giving you problems every time you need to get in and out? A faulty garage door opener isn’t just a nuisance — it’s a safety hazard that could endanger you and your loved ones. Unusual noises, opening by itself, and failing to respond reliably are all signs of a broken garage door opener.

Replacing garage door opener systems is not a DIY project. The process involves complex wiring, moving heavy parts, and specific calibrations, which are best suited for skilled professionals. We’ll walk through our six expert steps for installing new garage door opener units and review factors to consider so you know what to expect during the installation process.

Step One - Prepare for Installation

Precision Garage Door Service® professionals begin every garage door opener replacement by preparing the area for the new unit. Safety always comes first, so they'll start by disconnecting the power to avoid electrical hazards. Next, they'll disconnect the old or broken garage door opener unit and remove the remote control system, old brackets, rails, and sensors so they have a clear workspace for a seamless garage door opener install.

Steps on how to replace a garage door opener.

Step Two - Install New Rails

Work will officially begin once the service professionals install your new rails, which act as a guiding track for the garage door opener as it opens and closes. The type of rail system installed will vary depending on your opener’s drive system.

They'll then install the trolley or pulley system that helps lift the door on command. Professionals will know whether to use a belt or chain for this system based on your garage door needs and noise preferences. You must choose an opener powerful enough to lift your door consistently.

Step Three - Mount the Motor

The next step is to mount the motor that powers your garage door opener. The professional will install a sturdy bracket to hold the motor in place. They’ll anchor the bracket securely using an impact driver and heavy-duty screws. Proper mounting is crucial since the motor must be level and stable to work efficiently.

Step Four - Align the Sensors

Sensor alignment can be one of the more cumbersome steps for those learning how to change a garage door opener. The sensors detect objects in the door’s path and prevent it from closing on anyone or anything. Even the slightest misalignment can cause malfunctions, such as the garage door refusing to close or starting and stopping unexpectedly. A professional will position each sensor at the correct height on either side of the door.

Step Five - Connect Keypads and Remotes

Next, it's time to set up the control systems that allow you to operate the garage door opener inside and outside the garage. The professional will install a wall-mounted keypad in a convenient location, making opening and closing the garage door a breeze. They’ll program the new garage door opener and replace the old garage door opener remote if needed.

Step Six - Test the Opener

The final step is to test your new garage door opener to ensure it operates correctly. The service professional will open and close the door several times to guarantee it works smoothly. They'll also do a final safety check on the sensors to make sure the door stops and reverses if anything falls in its path. Professionals should also be able to help hook up and test any garage door apps you may want to use on your smartphone.

Factors To Consider When Choosing a New Garage Door Opener

Finding the best garage door opener is about finding the right balance of reliability and specific features that accommodate your needs. Here are the key factors to consider before making your final decision:

  • Opener type: Chain drive models are durable but noisy, while belt drive openers are quieter and ideal for residential areas. Direct drive systems offer smooth, low-maintenance operation.
  • Horsepower: A ½ horsepower motor suits most single doors, but heavier doors require ¾ horsepower or more for reliable performance.
  • Special features: Look for motion sensors and Wi-Fi connectivity to enhance safety and convenience.
  • Warranty: Purchase a warranty if it's not already included to protect the long-term value of your garage door opener.

You’ll be equipped to choose a garage door opener that stands the test of time by weighing these characteristics carefully and not rushing your decision.
