If you're like most people, you just expect certain things to work, all the time. Your garage door opener is one of them. Whether the door is open, or if it's closed and the remote won't work, there are a few things you can check in an effort to fix the problem. This guide explains what you need to do if your garage door opener ceases to operate as expected.
Replace the Batteries
Use a screwdriver to remove the back of the opener to expose the batteries. Check the size of the batteries and grab new ones from your garage, or purchase them. Place the new batteries in the unit, making sure they are in properly and replace the cover. Check the remote again. If it works, you're done. If not, continue with other troubleshooting tasks.
Test the Power Supply on the Receiver
Locate the outlet that supplies power to the receiver. Unplug the unit and plug in a fan or a blow dryer to test the outlet. If the outlet is working, plug the unit back in. If not, check the circuit breaker to see if it is tripped. If so, flip it back on and try the opener again. If it still doesn't work, call an electrician to repair the outlet.
Some receivers have battery backup in case the power goes out. If this is the case with your unit, replace the batteries. Sometimes the unit won't work even with electricity if these batteries are dead. Additionally, a garage door remote can't work if the receiver isn't.
Clear the Eye of Any Blockage
Find the safety sensors at the bottom of the garage door's track. You'll find one on each side of the door, so check them both. Remove items that are in front of these eyes and use a clean rag to wipe the eyes' lenses of dirt or anything else that might be stuck on them.
Note: This troubleshooting tip is only for when the door is open and the remote won't work. A blockage on the eye safety sensor doesn't have an effect when using the remote to open the door.
If none of these troubleshooting and repair tips work, call your garage door professionals to make a garage door repair appointment with them. They'll be able to perform more diagnostic tests to figure out what's happening. In the meantime, pull the safety rope to disengage the opener so you can open and close the garage door manually.
