One of the most common causes for the malfunction is a lack of battery power. If the batteries in the remote are too low or dead, they won't be able to alert the garage that it's time for it to go up or down. Remove the back of the remote and find out what type of battery is needed. Then try replacing the battery and see if it's working properly.
Inspect the Battery Terminal
If the batteries are working correctly, it could be the battery terminal causing the problem. The battery terminal makes connects the battery with other electrical components. If the terminal is dirty, wet, or worn, it won't function correctly. Check the terminal and make sure that it's dry and clean. If it's worn, the terminal needs to be replaced to get it to work.
Clear the Eye
The eye is a plastic piece over the IR unit. When the plastic is dirty, the receiver won't be able to transmit or receive any messages from the remote. Clean it off and then try it again. If the eye is scratched, try polishing it to remove the scratches that could be hindering the signal.
Reset the System
When a computer malfunctions, restarting it can get it working again. Similarly, a person can reset the remote to get it to work. Reboot the circuit board in the remote control by removing the batteries and replacing them after 30 seconds or the one in the received by pushing the reset button. To find the reset button, refer to the owner's manual.
Along with resetting the system, reprogramming the remote can help reboot the system. Check the owner's manual to find out how to do this for the particular model.
Order a Replacement
If all else fails, it could be that the remote malfunctioned or is damaged beyond repair. When this is the case, it's time to order a new remote. Choose one that works with the garage door. It might be helpful to have professionals help program the remote for you and make sure that everything is working as it should.
If there continues to be an issue with the overhead garage door, maybe the problem doesn't have to do with the remote at all. It could be failing to close because something is in the way, causing the safety sensors to prevent the door from closing. There could be an issue with power to the receiver or other issues with the equipment. If this is the case, we can inspect all of the parts and find out what's causing the issue. Then, we can fix it and make sure that the remote is working properly with the rest of the system.
