LiftMaster remote not working

May 17, 2012

Is your LiftMaster remote not working? If so, you should start reading this simple guide to troubleshooting your remote control or garage opener. Whether you want to fix the problem yourself or hire a technician to do it for you, you will need to determine whether the issue is caused by faulty installation, poor opener mechanism, or the remote control itself. Here are some tips for troubleshooting your LiftMaster remote and Chamberlain garage door opener.

Garage door does not operate from remote control or push button

If you keep on pressing your LiftMaster remote but the garage door opener does not budge, there is a possibility that there is no power. Check the outlet and make sure it has power before plugging the garage door opener into it. You may also want to check the circuit breaker or fuse box before jumping into conclusions. If it there is power but your garage door opener still failed to operate, the overload protector may have also tripped in the motor. Wait for the motor to cool down and try operating it again after fifteen minutes or so.

Door operates from push button but not from the LiftMaster remote

If this happens, your remote control battery may already be dead. Change the battery before trying to operate your garage door or gate openers. It is also possible that your LiftMaster remote is not sending a signal. If you have more than one remote for your garage door, make sure that both of them are operating. The lock switch may also be activated so you have to check the blinking light on the Control Panel. If so, push the button to turn the lock switch off. You can also try coding your LiftMaster remote to the receiver by researching more about remote codes.

Door operate from LiftMaster remote but not the push button

When troubleshooting your garage door remote, you should also consider checking the status of the door control push button. If the door control seems defective, you have to disconnect its wires and see if the unit operates. If the unit does not work, you may have to replace the door control. Next, open the bell wire and try disconnecting its wires from the logic board before checking if the unit operates. If not, you can either repair or replace the dysfunctional bell wire.

Garage door closes or opens by itself

If your garage door starts opening or closing by itself, your LiftMaster remote may also have a problem. One of its buttons may be stuck so you have to check all of your garage door remotes and inspect the LED light of the receiver. The staples around the Multi-Function Control Panel may also be cutting into the bell wire. To fix this problem, try removing the wires from the opener before testing them. Replace the staples that have been causing intermittent short circuits.

LiftMaster remote has a very short range

If your LiftMaster remote seems to have a short range, its batteries may already be weak. Try replacing the battery before operating the garage door. If this does not work, try pulling down the visor of your car before re-testing the remote. If this step allowed your LiftMaster remote to operate more efficiently, you have to keep the visor down whenever you need to use the remote. RF interference may also be causing the problem so you have to locate the interference and disable it if possible. Every time your LiftMaster remote not working, try this step-by-step guide to troubleshooting it yourself.
