Had excat same problem. In our case it was that the two sensors on either side of the door were slightly misaligned. The greed LED on the one sensor was solid green; the LED on the other was flashing. I moved the sensor with the flashing oight around until it showed a solid green LED. When i pushed the wall button it wokred perfectly. Our doors are about 15 years old and the sensores were very loose. Once you agn them, tighten the wing nuts and check them periodically.

Why Can't I add another remote to a merlin mt60p


If you purchase additional transmitters, the garage door
opener must be programmed to accept the new remote
code.
Program the Receiver to Match Additional Transmitter
Codes:
Using the orange "LEARN" Button:
1. Press and hold down the transmitter button you wish to
program to the opener. The orange LED will flash to
indiciate it is receiving signal from the transmitter.
2. Press and release the "LRN" button.
3. The sourtesy LEDs will flash once.
Ensure the door is clear of obstruction, then test the
transmitter.
Using the Motion Detecting Control Panel
(optional accessory):
1. Press and hold the button on the hand-held remote that
you wish to operate your garage door (1).
2. While holding the remote button, press and hold the
LIGHT button on the Motion Detecting Control Panel (2).
3. Continue holding both buttons while you press the push
bar on the Motion Detecting Control Panel (all three
buttons are held) (3).
4. Release buttons when the opener light flashes. It has
learned the code. If the light bulb is not installed, two
clicks will be heard (4).
Now the opener will operate when the transmitter push
button is pressed. If you release the transmitter push button
before the opener light flashes, the opener has not learned
the code.
To Erase all Transmitter Codes:
To deactivate any unwanted remote, first erase all codes:
Press and hold the orange "learn" button on opener until
the learn indicator light goes out (approximately 6 seconds).
All previous codes are now erased. Reprogram each remote or keyless entry you wish to learn.

Door goes down and when it stops at botton, it turns and goes back up ??? Need adjusting ..How can I adjust???


Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close)
Setting the up position: 1. Press and hold the black button until the LED starts flashing slowly, then release. 2. Push and hold the black button until the door reaches the desired UP (open) position 3. Push the door control or programmed remote control. This sets the Up (open) position and begins closing the door. 4. Immediately when the door begins to close press and release the black or purple button. This will stop the door Setting the Down position: 5. Push and hold the purple button until the door reaches the desired DOWN (Closed) position. 6. Once the door is closed, If there appears to be too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position. 7. Push the door control or programmed remote control. This sets the Down (closed) limit and the door should open.

Wall mount button LED is flashing, remotes won't work, door won't close unless the wall mount button is held down until the door is fully closed


Sounds like you have a couple problems. First of all press and hold the button on the wall control that has a lock icon for 3 seconds and release. This should take care of the flashing LED and the remotes will now work. Having to hold the button on the wall control until the door is closed is usually a problem with the door sensors. Make sure they are pointed at one another and the small light on each is lit and not flickering.

My garage door wont go down.I habe to hold the switch down but if i let it go the door will go up again.


I have a Liftmaster garage door that won't go down unless you press and hold the wall button. The sensor lights are both on. The green light on the unit flashes unless I press the reset button. As soon as you press the wall button it flashes again and the door won't go down unless you hold the button the whole time. The remote wont' make it go down either. It begins to sometimes and retracts, but sometimes the light bulb just flashes (like it is obstructed). I tried replacing the wall switch and that did nothing. Help!

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.

Remote unit of garage door not able to close garage door


Does the safety feature react when blocked?  If not, the problem may not be with the remote.
The low force switches used in most remotes are very simple devices and fairly reliable but they can fail over time. They are one of two common types; one is a carbon button molded to a silicone sheet with one or more buttons attached and with the user side marked and protruding through holes in the case. The button contacts a circular area on a printed circuit board that once was flashed with a thin gold plating that never corroded. In more recent times, they have dispensed with the gold and you now have the tin plating of the circuit board only and this tends to lose its conductivity with time. These can often be restored by exposing the printed circuit board and using a standard pencil eraser to gently scrub the contact area. Because of some waxy component of the eraser, it is wise to clean the contact pad with a cotton swab and some alcohol before closing up the case.
The other type of 'soft touch' switch uses a thin, dome-shaped metal contact that is depressed to make contact. These don't suffer from contaminants as much as fatigue and may not want to 'pop' back after being depressed. This type may or may not be restorable depending on how they are held in position.
Finally, if you have a 'police' scanner, you might be able to use it to detect whether your remote is putting out any signal at all by allowing the scanner to scan up to ~500 MHz since most of the RF remotes use frequencies below this point. With the scanner scanning, you would just hold down a working button of the remote until the scanner stops on that frquency then, overlapping, press the non-working button to see if the scanner finds it again. If not, the remote is at fault. If the scanner finds the signal with all buttons, then the receiver is at fault and without some technical skills and equipment, there isn't much you can do at home.
