Garage Door trouble

My garage door will close if I push the button inside the garage and it will open that way but my little hand held opener will not close or open the door if I am standing outside the garage.
Thank you,

Why won't my Genie garage door opener close without going back up.


So it seems the Main garage door unit on the ceiling is ok. The problem is with hand held unit. Usually the circuitry is ok. Try changing the battery. It has helped me. Also make sure the sensor on ceiling unit is not blocked ad is free of cobwebs.

I don't have the owner's manual for my 2002 GMC Yukon XL Denali. Do you know how to program the garage door opener?


I hope this helps.

Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the stop and reverse
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Decide which one of the three channels (one of the
HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly (this may
take up to 90 seconds).
If you have trouble programming HomeLink, make
sure that you have followed the directions exactly as
described and that the battery in the hand-held
transmitter is not weak. If you still cannot program it,
move the hand-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to "Training a Garage Door Opener with
Rolling Codes" later in this section or contact the
manufacturer of HomeLink at 1-800-355-3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand-held transmitter in
case you need to erase and reprogram HomeLink.


Training a Garage Door Opener with a
"Rolling Code" Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to HomeLink, see "Programming the
HomeLink Transmitter" listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the "Learn" or "Smartbutton" on the garage
door opener motor head unit. The exact location and
color will vary by garage door opener brand. If you
have difficulty finding the Learn or Smart button,
refer to your garage door opener owner's manual or
contact the manufacturer of HomeLink at
1-800-355-3515, or on the internet at
www.homelink.com.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.
2. Press the Learn or Smart button on the garage
door opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.
3. Return to HomeLink in your vehicle and firmly
press and release the programmed HomeLink button
three times.
The rolling-code garage door opener should now
recognize HomeLink. You may either use HomeLink
or the hand-held transmitter to open the garage door.
If after following these instructions, you still have
problems training the garage door opener, contact the
manufacturer of HomeLink at 1-800-355-3515,
or on the internet at www.homelink.com.

I have 2 liftmaster 3245. The hand held remotes were working fine then stopped. I replaced the batteries and turned of all electrical/RIF close by. Still not working. Both cars operate the doors with no...


You need to reprogram the remotes by briefly pushing the learn button on the garage door opener until it flashes once, then release the button on the garage door opener.

Now press the remote button once until you hear the garage door opener click, now press the remote button once again and the remote should be programmed to work for that garage door opener.

DO NOT press and hold the garage door opener learn button for more than 10 seconds or you'll erase all programs and have to relearn all the remotes, including your car ones.

Hope you found this very helpful and best regards.

Have to hold the push button inside my garage to close garage.


You have a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not blinking. Also check the wiring.

Must hold wall unit to close garage door...


there is an error in the system. most likely The safety beams (mounted on the track near the floor) are out of alignment and the LED light should be blinking. The garage door opener will not let the door close if the beams are misaligned. Realign them and the LEDs on the beam or on the operator will stay on. you should be able close the door now with one push.

Program 2004 mercury mountainer garage opener


Verify the hand-held transmitter is operative.
Prepare for programming the universal transmitter by erasing all three channels (hold down the two outside buttons until the red light begins to flash [20-30 seconds]). Release both buttons.
Select one of the three universal transmitter channels to be programmed by pressing the desired button
Hold the end of the hand-held transmitter 25-51 mm (1-2 in) from the front surface of the universal transmitter so that the red light can still be seen
Use both hands to press the hand-held transmitter button and the desired button on the universal transmitter. Do not release either button.
Hold down both buttons until the red light on the universal transmitter flashes, first slowly and then rapidly. Release both buttons when the rapid flashing begins. The universal transmitter has successfully learned the new frequency signal and can be used in place of the hand-held transmitter(s).
If the hand-held transmitter appears to program the universal transmitter but does not open the garage door, the garage door opener may have a code protected or rolling code feature.
To operate, simply press the appropriate button on the universal transmitter. The red light is on while the signal is being transmitted.
IF THE GARAGE OPENER HAS ROLLING CODES---
program as above then------
Train the garage door opener receiver to recognize the universal transmitter.
Remove the cover panel from the garage door opener receiver.
Locate the training button on the garage door opener receiver. Location and color of the button may vary by garage door opener manufacturer. Refer to the garage door opener instruction manual or owner literature.
Press the training button on the garage door opener receiver for 1-2 seconds.
Press the programmed universal transmitter button for as long as the universal transmitter red light flashes (1-2 seconds). Release the button and re-press the button to confirm that the universal transmitter is trained to the receiver.
The garage door opener should recognize the universal transmitter.

Garage door opening/closing problem


Could be a bad wall button or a smashed wire.
Anytime a door opens and/or closes by itself, or remotes work intermitantly I look for a smashed wire between the motor unit and the wall button or a bad wall button.

If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote.

Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.

The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.

The test is to disconnect the push button wires at the power unit. If the self operation / interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.

HOPE THIS HELPS
