Garage Door Opener Repair: How to Troubleshoot Openers

Fix: Replace batteries or buy a new remote or receiver

If the wall switch works but one of the remotes doesn't, check the batteries first. Still nothing? — You may need a new remote. Home centers carry a few models, and you can find a wide selection online.

If you can't find one for your garage door opener model, you can try a universal remote or you can install a new receiver. A receiver replaces the radio frequency the opener uses with its own. An added bonus of a new receiver is that it will automatically update older openers to the new rolling code technology, which stops the bad guys from stealing your code. Just plug the new receiver into an outlet close to the opener, and run the two wires provided to the same terminals the wall switch is connected to. A receiver with one remote costs around $60.

Reports from Field Editors

“No special training or online course is needed to fix a garage door opener. The only requirements are patience, a DIY aptitude and determination.”

Dave Pike is a Field Editor from Stillwater, MN. DIY is his approach for everything, except furnaces and new cars.

“After several years of operation, nylon gears will wear out, especially if your door isn't properly balanced. I found that replacing mine was an easy and relatively inexpensive fix.”

Pete Grealish is a Field Editor from Pocasset, MA. His favorite project was restoring his 1982 John Deere 214 garden tractor, but his wife's favorite project was the central air conditioner he installed.

“Always use rough-duty bulbs in your opener. You won't have to change them as frequently.”

Steve Yaeger is a Field Editor from Eagan, MN. He is on a lifelong quest to design and build the perfect workbench.

    • You may have to readjust the limits on the door. The limits are what make the door stop when it is all the way up or all the way down. When you replaced the gears the limits might of been at all the way up and you are trying to open the door but the limits think it is already open. Check your user manual(or one on line) for how to check and adjust your limit switches.
