Problem: The automatic opener
does not open the garage door.
Background: An electronic garage door opener may
not activate be cause its power supply is interrupted, its
antenna is out of position, its transmitter is defective,
its remote battery is expired, or its push-button switch
inside the garage is defective. First make sure the unit’s
receptacle inside the garage is receiving power, and that
the opener is plugged in.
What to do: To determine if the transmitter or its
battery is bad, simply see if the opener operates when the
push button inside the garage is activated. If it works
with the push button, next check to see that the unit’s
antenna is not bent out of position. Try replacing the
transmitter’s battery. If the transmitter still doesn’t
work, its button may be defective. Try cleaning it with
electrical contact cleaner. If that doesn’t correct the
problem, you will most likely need to replace it.
Conversely, if the transmitter works but the push button
inside the garage doesn’t, turn off the power and clean
the push button with electrical contact cleaner. If that
doesn’t fix it, turn off all power and replace the switch
simply by removing and detaching the 2 wires that are
under the screws on the back, and reinstalling a new
Special advice: When a power failure traps your car
inside the garage, pull the emergency release mechanism
located on the opener track. Usually, this will be a cord
hanging down between the opener motor and the door. Pull
the disconnect cord down and away from the door to release
it. Important: If you disengage the
emergency release during a power failure, be sure to also
unplug the garage door opener. After the power is
back on, pull on the emergency re lease again to re-engage
the opener. Make sure all drivers in your house hold know
how to use the emergency release mechanism.
