Why do you need a functioning and well-maintained garage door opener?

A garage door is the biggest moving piece that your home has. It has to endure all the weather conditions and your odd driving. While the garage door needs regular maintenance (every 3000 cycles), its door openers also require routine maintenance.

The main reasons for a functional and well-maintained garage door opener are–

  • It helps to shut your garage door.
  • Openers help to keep unwanted intruders out of the home.
  • They help to prevent accidents or injuries that the heavy manual garage door would’ve caused.
  • It helps to reduce the extra noise during the opening and closing of garage doors.
  • They also come in handy during disasters. E.g., if the power goes off for a couple of days, you can still use your door opener a dozen times.
  • Openers also provide homeowners convenience and ease of use by facilitating buttons, Wi-Fi connectivity, and automatic lights.

Step-To-Step Process To Install A Garage Door Opener

When to replace a garage door opener? – Before diving head first into the steps to install a garage door opener, let’s look at some of the signs on the door that scream “change the garage door opener“–

Sign 1: The garage door is stalling, sticking, and refusing to open.

Sign 3: The garage door operation is loud.

Note: In this case, the door either needs lubrication or a replacement.

Now that you are fully aware that your garage door repair needs a new installation, let’s look at the steps–

Step 1: To mount the opener: Choosing the right location for an opener

The first step is to locate the ideal place to mount your garage door opener. Ensure enough space between the ceiling and the opener, with no obstructions like wires or pipes. Additionally, you must mount the opener in a central position allowing easy access.

Step 2: Installing mountain brackets

Once you have a designated location, install the mounting bracket. The bracket should be attached to the ceiling with sturdy bolts and screws. Before proceeding to the next step, ensure the bracket is firmly in place.

Step 3: Attaching the opener to the bracket

The next step is to attach the garage door opener to the previously installed mounting bracket. Try to align the opener with the bracket and bolt using the provided hardware. After bolting the opener to the bracket, ensure it’s level.

Step 4: Wiring the opener

Wire the opener to the power source by running a cable from the opener to an outlet, i.e., your home’s electrical system.

Step 5: Testing the opener

Before using the garage door opener, testing it to ensure everything functions smoothly is essential. Test the opener by opening and closing the garage door to ensure everything works correctly. Take note of any unusual sounds or movements and address them accordingly.

Step 6: Troubleshooting issues

If you observe any issues during the installation or testing, refer to the user manual or seek professional assistance. Here are some troubleshooting issues–

  • Unresponsive remote controls
  • Misalignment
  • Incorrect wiring

Common problems with garage door openers

Now that you know how and when to replace or install a new garage door opener, let’s look at some common problems with garage door openers that need repairing.

a. Misalignment

Over time, the tracks that guide the door get bent or warped, causing the door to come off its alignment. This issue can result in the door being unable to open or close properly. However, in some cases, the door may get stuck halfway, leaving the homeowner unable to use the garage. Misalignment can also cause strain on the motor, leading to burnout or failure.

b. Faulty sensors 

A sensor detects any obstruction in the door’s path and stops the door from closing on people or objects. If the sensors malfunction, the door may close on something, causing damage or injury.

c. Opener Motor Issues

There can be a problem with the garage door opener motor, such as issues with wiring, electronics, or the engine itself. The opener won’t work if the door opener’s motor fails.

d. Power supply issue

The garage door opener often malfunctions due to the power issue. The opener won’t work if there’s no power in it.

Steps to take before repairing a garage door opener

Now that you have located where or what the problem is, here are the steps to prepare for repairing a garage door opener.

Step 1: Inspect the Door 

Inspecting your garage door thoroughly to check if it functions correctly is essential. Check for any obstructions that may prevent the door from opening or closing, any physical damage or wear to the door, or any loose bolts or damaged tracks or springs.

Step 2: Disconnect the Power

Always turn off the power to the garage door opener before starting any repair work. Now, disconnect it from the power source to avoid electrical shocks or short circuits during repairs.

Step 3: Gather the Necessary Tools

At last, you must gather the necessary tools and spare parts to repair the garage door opener.

Step-To-Step Process to Repair a garage door opener

How to repair a garage door opener? – This query always gets in our way. Here are our guided steps to repair a garage door opener.

Remember: Any issue beyond what we’ve discussed (below) about repairing needs professional help.

Step 1: Replacing the motor

Inspect the driving force behind the garage door opener’s movement to replace the motor. The engine may become damaged due to wear and tear, overheating, or electrical issues. Here’s how to replace it–

  • Remove the cover and locate the motor.
  • Disconnect the power source from the garage door opener to replace the motor and release the tension on the chain or belt.
  • Take out the motor’s mounting bracket.
  • Disconnect the motor from the opener by unplugging the wires.
  • Remove the screws that attach the motor to the opener and remove the engine.
  • Fit a new motor into the opener and screw it into place using the screws.
  • Now finish the process by simply connecting the wire to the new motor and replacing the cover.

Step 2: Replacing the circuit board

A circuit board is the brain of the garage door opener. Its role is to interpret the user’s input, process, and control the garage door opener’s movement. The garage door opener may not function or behave erratically if the circuit board fails.

Here’s how to replace it–

  • Disconnect the power to the opener and remove the cover.
  • Locate the circuit board and unplug the wires.
  • Remove the screws that attach the compatible circuit board to the opener and replace it with a new one.
  • Plug in the cables and replace the cover.

Step 3: Replacing the chain or belt

The chain or belt links the garage door opener and the garage door’s movement. Remember, chains or belts may become damaged or worn out due to excessive use. It can also damage due to exposure to environmental factors such as dirt, dust, or moisture.

Here’s how to replace it–

  • Disconnect the power to the opener.
  • Remove the cover and locate the chain or belt.
  • Loosen the bolts that hold the motor to the opener and remove the old chain or belt.
  • Fit a new chain or belt by wrapping it around the engine and the opener.
  • Tighten the bolts that hold the engine to the opener and replace the cover.

How to maintain a garage door opener?

You can easily maintain a garage door opener. Here are some maintenance tips for your garage door opener–

  • Lubricate the moving parts like rollers and tracks of the garage door often to prevent rust and provide smooth movement.

Note: You must use a silicone-based lubricant. It does not attract dirt or dust.

  • Check the hardware, such as bolts, nuts, and screws, at least once a year to ensure they get tightened securely. Loose hardware causes the garage door opener to malfunction or even fall.
  • Now, check the weatherstripping at the bottom of the garage door regularly. Weatherstripping can deteriorate over time and cause drafts and leaks. So, replace it to maintain energy efficiency.
  • Routinely test these features to ensure they work properly. All garage door openers have safety features such as auto-reverse and photo-eye sensors.
  • Regularly clean your garage door opener and surrounding areas to prevent dust and debris from accumulating.
