How can a noisy garage door be fixed?

·         Dirty, worn or wet contacts inside of the battery case inhibit the electrical current of the batteries from fully reaching the circuit board inside of the remote control. If the contacts look discolored, pitted or are wet, they need to be dried and polished before any battery can successfully power a remote control. Contacts can be polished with a fine-grit sandpaper, like 400-grit or fine steel wool.

·         Clean the Eyes

·         The plastic covering over the IR unit on both the remote control and the receiving unit is called the eye. This "eye" allows the IR signal to pass through it in both transmitting and receiving. Eyes can be wiped off using a soft damp cloth. Most remote eyes are made of plastic that, although resistant to scratching, become scratched if rubbed against metal, abrasive fibers or dropped onto the ground. The plastic can be polished using specialized plastic polishing substances, but if the IR eye on a remote control is badly scratched, pitted or gouged, there may be no recourse except to get a new one.

·         Reset the System

·         Remote controls and receivers are small computers. Sometimes a reset is needed to reboot the circuit boards in both the remote control and the receiver. A reset is accomplished by removing the batteries in the remote for approximately 30 seconds and re-installing them. A reset on a receiver is accomplished by unplugging the unit from the wall socket for a bout 30 seconds, then plugging it back in.
