Why does garage door keep going back up?

The garage door closes but then opens again, or the door shuts on its own– we all have been there!  It’s a potential security risk and a major headache.

The confusing question that arises in such a moment is, ‘Why does garage door keep going back up?’ It might be a sensor malfunction, a misaligned switch, or something else entirely.

This blog will help you to diagnose the problem and get your garage door back on track. So, let’s get started!

Why does garage door keep going back up? Common reasons

Why does garage door keep going back up Common reasons

Understanding the common reasons why your garage door keeps going back up is the first step toward resolving this frustrating issue. Here are some of the most frequent causes–

  • Sensors misalignment

Garage door systems are equipped with safety sensors that detect obstructions in the door’s path. If these sensors become misaligned due to accidental bumps or vibrations, they may incorrectly signal that there is an obstruction, causing the garage door goes back up after closing.

  • Blocked sensors

If the garage door thinks the door is blocked, it may move back up. This can be caused by a blockage, dirty eyes, loose wires, or bad sensors. A blinking sensor light is one sign of a malfunctioning infrared sensor.

  • Malfunctioning remote control

Issues with the garage door remote control, such as weak or depleted batteries, signal interference, or programming errors, can also cause the door to behave erratically. If the remote control signal is not properly received by the opener unit, the door may close partially before reopening.

  • Faulty springs or cables

The springs and cables play a crucial role in the smooth operation of the garage door. If these components are worn out, damaged, or improperly adjusted, they can hinder the door’s ability to close properly, leading to unexpected reversals.

  • Blocked photo eye

The photo eye is the safety feature that stops the door from closing if it senses any obstruction. If the photo eye is blocked or misaligned, the garage door won’t close all the way.

  • Swollen or draining capacitor

If the capacitor is swollen or draining, replace it. The capacitor is a white cylinder that can be found by unscrewing the back of the garage door motor unit.

  • Power Interruption or Electrical Issues

In some cases, power interruptions or electrical problems within the garage door opener unit or the electrical circuit supplying power can lead to erratic behavior, including the door closing and unexpectedly reopening.

Before you reach for the phone to call a professional, let’s explore some simple troubleshooting steps you can try to address the underlying cause of the issue. 

  • Check the sensor

Start by inspecting the safety sensors’ alignment near the bottom of the garage door tracks. Make sure they are properly aligned, facing each other, and that no obstructions are blocking their line of sight.

  • Clear Obstructions

Examine the area around the garage door for any objects or debris that may be obstructing the door’s path. Even small items like rocks, toys, or tools can trigger the door to reverse and reopen. Remove any obstructions to allow the door to close smoothly.

  • Check the batteries

If you’re using a remote control to operate your garage door, check the batteries to ensure they are not low or depleted. Replace the batteries if needed, and try reprogramming the remote control according to the manufacturer’s instructions.

  • Check the circuit board

A damaged circuit board can cause the door to open and close. You can enlist professionals to inspect the circuit board to repair or replace it.

  • Test manual operation 

If all else fails, try operating the garage door manually by disconnecting it from the opener mechanism. If the door closes smoothly and stays closed manually, the issue may lie with the opener unit or remote control system.

When to Call a Professional garage door repair service

Knowing when to seek professional assistance for your garage door issues can save you time, effort, and potential safety risks. While some problems can be easily resolved with DIY troubleshooting, others require the expertise of trained professionals. 

Here are some signs that indicate it’s time to call a professional garage door repair service–

  • Electrical issues

Messing with electrical components can be dangerous. If you suspect any electrical problems with the opener, sensors, or wiring, leave it to professionals with the proper training and equipment. 

  • Broken springs

Garage door springs are under immense tension and can be extremely dangerous if handled incorrectly. Replacing or repairing them requires specialized tools and knowledge, making professional intervention crucial.

  • Complex repair

Misaligned tracks, faulty opener mechanisms, or extensive damage require comprehensive assessment and specialized repair. Trusting a professional ensures proper diagnosis, safe execution, and long-term solutions.
