Press the button on the built-in transmitter that connects to the wall to raise or lower the door. The built-in transmitter has a 110-volt electrical source instead of batteries. If the garage door works when you press the built-in transmitter but not when you press the remote transmitter in the car, replace the batteries in the remote transmitter. Place a ladder directly under the liftmaster garage door opener main housing, which bolts in the ceiling of the garage, and inspect the power cord that is connected to the wall socket.

If you are using an extension cord to connect the power cord to a wall outlet, make sure it is connected. If it is, pull out the garage door opener and plug in a known working device to ensure that the power outlet is working. If it does not, check the circuit breaker panel for a tripped switch. Locate the eye sensor on the front of the house. The eye sensor receives transmissions from remote sensors and responds to the buttons you press. If the sensors have dirt or dust on them, the door may not work. Wipe the sensors clean with a dry cloth. In addition, the sensors on the remote transmitter clean.
