The problem is that your system does NOT "see" the safety "eyes" sensors. Make sure that your sensors are properly connected to the opener (both sensors should have lights on them, one amber and another green). If they do not, check the wiring and the connections at the opener itself.

  1. Press and hold the Lock button until the light blinks (about 10 seconds).

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.

Liftmaster pro 1/2 hp wont shut in one button press


You have a door sensor problem. Either your main light bulb is burned out or you don't have one in your opener. The clicking sound you hear is the relay for the light. Both of the door sensors should have a small light that is lit. Tweak them until they are.

Having trouble setting garage door opener to my 2004 trailblazer


1. Position vehicle within 10 feet of garage door- engine off and battery on.

2. Press/hold 2 outside buttons of Homelink transceiver until red indicator starts flashing rapidly, then release button. This should take about 20 seconds. This erases any previously learned codes.

3. Press/hold remote control and press/hold button of Homelink transceiver simultaneously. Slowly move remote control from 5" away to 1" away from Homelink transceiver. Release both buttons after red indicator starts blinking rapidly. This should take about 5 seconds. I discovered that the Homelink in my TL is a bit faulty because it took much longer to accomplish this than when programming the Homelink in my MDX. My TL's Homelink may "unlearn" it's code in the future and the needed proximity of the TL to the garage door may be much closer than desired until I get the Homelink fixed.

4. Press training button on garage door opener unit until the indicator lights illuminates- this should be immediate.

5. Within 30 seconds press/hold the Homelink button for 2-3 seconds until the red indicator starts flashing rapidly. Repeat a second time. It should now be programmed. Check it by pressing the programmed button on the Homelink receiver.

6. When programming more than 1 garage door opener unit, disconnect power from unit before programming more units. By not doing this the programmed unit could conflict with the unprogrammed units commands.

Problems:

1. The Battery in the garage door remote may be too weak to program Homelink. However, the battery may be strong enough to operate the garage door. One of my remote controls had a weak battery- my system was installed today, fresh out of the box. I had to use the second remote control for the programming of Homelink on my 2 vehicles.

2. Antenna on the garage door opener unit must be hanging down, fully extended.
