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 switch.
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.
Helpful hint: For routine adjustments, and consult the opener owner’s manual. If you don’t have an owner’s manual, contact the manufacturer and request a copy for your specific model. The opener model number should be on the back of the power unit.
