Garage Door Troubleshooting Tips

You count on your garage door opener to function so you can get your car in and out of the garage. If you’re experiencing a problem, try these garage door troubleshooting tips to get things working again.

Door Won’t Go Up

Before you blame the opener, check to see if the problem lies with the door. From the closed position, pull the emergency release cord hanging down from the trolley carriage. Now, attempt to lift the garage door by hand. If it feels too heavy to lift, something is wrong with the tracks, springs, cables or rollers. Repairing these components can be dangerous, so you should leave the task to a professional.

Door Won’t Go Down

If the door only goes down when you hold the wall switch, the safety sensors might be out of alignment. Holding down the wall switch is a safety override, but you want the door to operate normally so you can use your remote.

Look in the bottom corners of the garage door for small light sensors. They should both glow to indicate that nothing is between them and the door is safe to operate. A little adjusting should realign the beam. If no light is showing from either sensor, you should replace them both.

Dysfunctional Wall Switch

If the remote works but the wall switch doesn’t, the switch itself or the wires behind it may be faulty. Unscrew the switch from the wall and locate the two wires inside. Touch them together (don’t worry—the low voltage wires won’t shock you) and see if the door operates.

If it does, simply replace the switch to get things working again. If it doesn’t, this means the wires are bad. Make sure the staples holding them to the wall aren’t pinching and shorting out the wires. If you decide to replace them, choose 18- to 22-gauge wire.

Dysfunctional Remote

If the wall switch works but the remote doesn’t, change the batteries. If you still get nothing, replace the remote with a model compatible with your garage door opener. Can’t find one to match your ancient opener? Try a universal remote or install a new receiver compatible with modern remotes. As an added bonus, this updates your opener to the new rolling code technology for added security.

Installing a new receiver is easy. Simply plug it into an outlet close to the garage door opener and run the wires to the same terminals on the back of the opener that the wall switch is connected to.

Grinding Sounds Coming from the Opener

If the opener makes a grinding sound but the door doesn’t operate, there could be a problem with the main drive gear. This is a plastic component that links up with the worm drive gear on the motor.

The main drive gear is the most liable component to fail, but replacing it can be a bit complicated. You need to take apart the opener and remove several other parts before you can even reach the gear. Once it’s out, you need to replace it with a new gear and shaft, lubricate the assembly, and rebuild the garage door opener. If this sounds too tricky, leave the repair to a professional.
