How to check signal from garage door remote.

Oftentimes when your garage door opener remote stops working it is because the remote transmitter has lost its signal with the motor. Every garage remote has a radio transmitter in it while the garage door opener has a matched radio receiver. Troubleshooting a lost signal on your remote is as easy as resetting the old signal. Batteries are important when using garage remotes.

In order for the remote to be able to open the garage door the signal from the radio transmitter must be strong enough to reach the radio receiver in the garage. This is accomplished with a series of tiny switches inside the remote control and on the opener. If your remote works correctly check that the opener s antennae doesn t have any excess debris buildup is pointed toward the door and isn t broken. The remotes work by electronically sending a signal to the motor inside your garage allowing you to open and close the door.

Most modern garage door openers have a coding system so that someone else with a remote can t easily get your door open with their remote. Stand within 20 feet of your garage door and attempt pressing the button if your remote is further away from the door the signal won t be strong enough to prompt the door.
