10 Common Garage Door Problems and How To Fix Them

Now that you understand what you need and what safety precautions you must take, let’s get down to brass tacks and diagnose your garage door’s problem.

Bad Remote Battery

One of the easiest, and most common, issues with garage doors not working is your remote’s battery is dead. Here’s how to test it.

  1. If you have a second remote that works, pull it out.
  2. Swap batteries with the first remote.
  3. If it worked, all you need is a new battery. 
  4. If you don’t have a second remote, simply buy a new battery.

Unsynced Garage Door Remote

Did you know your garage door remote might unsync itself, and you’ll have to reprogram it? Now you do! You’ll need to consult your garage door opener owner's manual to find your garage door’s remote programming procedure. 

Broken Garage Door Wall Opener 

Like your garage door opener’s battery, your wall opener can lose power from frayed wires or a broken switch. Here’s how to fix both.

Frayed Wires

  1. Disconnect the power at the fuse box to the garage.
  2. Once the power is off, remove the section of the frayed wire using wire cutters. 
  3. Splice in the section of the new wire using electrical tape, connectors like Posi-Taps, or soldering. 
  4. Reconnect the power and test the garage door.

  3. Disconnect and remove the wall opener.
  4. Replace and connect the new wall opener.
  5. Reconnect the power and test the garage door.

Broken Garage Door Motor

  13. Test the new garage door motor.

  1. Disconnect the power at the fuse box to the garage.

  13. Pull the cable around the idler pulley.
  14. Connect the cable to the trolley.
  15. Connect the new master link to the trolley.
  16. Making sure the chain isn’t twisted, connect the new chain to the motor.

Unlubricated Garage Door Hinges

As a garage door ages, it will lose some of its lubrication. Here’s how to fix that.

  1. Shut the garage door.
  2. Using a ladder, unplug the garage door from the outlet on the ceiling. 
  3. Vacuum out the garage door’s tracks.
  4. With a damp rag, wipe down the garage door’s tracks and hinges.
  5. Spray the garage door grease on the garage door’s hinges, rollers, and tracks. 
  6. Spray down the outside bearing plates (the two circular metal pieces on each end at the top of the garage door).
  7. Using the ladder again, spray the grease along the top rail that goes to the garage door motor. 
  8. Wipe away any excess grease.

Garage Door Off Its Track

A slightly trickier issue is when your garage door pops off its track. There are a myriad of reasons how and why this can occur, but rather than spending time describing every situation, it’s happened so let’s get through it. Here’s how to put your garage door back onto its track. 

  1. Using a ladder, unplug the garage door from the outlet on the ceiling.
  2. Release the door from the garage door opener’s chain.
  3. Find the wheels that are off their track and lock a pair of locking pliers just underneath them.
  4. With a rubber mallet, knock the wheels back onto the track. 
  5. Once they’re back, manually open and close the garage door. If it works, you’re done.
  6. If the wheels pop out again, your track may be bent. Using the rubber mallet, you can bend it back into position. Test the track again. If it works, you’re good.

Garage Door Closes Then Opens Immediately

One easy-to-fix issue is when your garage door closes, then immediately opens back up. There are two reasons this will happen. First, if there’s something obstructing the garage door sensors, and second, if the sensors are misaligned. The first will just require removing the object. As for the second, here’s how to align them.

  1. With the garage door remote in hand, close the door.
  2. As it gets closer to the ground, attempt to align the two sensors so that the infrared beam lines up. This may take a few attempts.
  3. Once the garage door closes and remains shut, you’re done!

Garage Door Seals Are Broken/Falling Off

Garage door seals can crack, break, and fall off over time. Although many will survive with broken seals, the seal at the base of the garage door can lead to higher heating and air conditioning bills as warm and cold air impacts the inside door to your home. Here’s how to repair the seal.

  1. Open the garage door.
  2. Unscrew/detach the old/broken garage door seal. 
  3. Install the new seal.
  4. Close the garage door to make sure you have a tight fit. Adjust as necessary.
