The colour on the sensors doesn't change.
One is orange constantly and the other is green when detecting a signal from the orange sensor.
If the green is flickering, they are not adjusted correctly.Move the green sensor until you get a good solid green. Holding the wall pad button down, just bypasses the sensors.

Try adjusting only the sensors so that they are solid.

In addition, check the little yellow light on the back of the machine and count the flashes.
The number of flashes will tell you what the error is in your manual.

HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

THERE ARE LED'S THEY SHOULD BOTH BE LIT - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?

IF ALL ELSE FAILS GET SOME DOORBELL WIRE AND BYPASS THE EXISTING WIRES AS A TEST - BE SURE TO CHECK THE POLARITY & LOOSE CONNECTIONS.

One sensor should always be yellow, the other should be SOLID green.
If the lights are not consistently SOLID, you have a sensor issue.
TEST: If the door closes completely by pressing and holding down the wall pad button, you have a sensor problem.

Check to make sure the are aimed properly at each other.
Check the wire at the sensor and more importantly at the machine (If the wires are loose at the machine (terminals) it can cause this problem. Remember the machine does shake a lot.
If the wires are good, the sensors are aimed correctly, you have a sensor issue and need to loacte a replacement set.

The garage door works when it wants to.


You have a problem with the safety eyes. Make sure a light is on on both eyes. If not, realign until both lights come on.

Check to see if the Vacation switch is locked on your wall console. It is a switch on the top of the black wall button. If that is not the problem it sounds like you need to program your remotes. Drop down the plastic cover towards the back of the unit There is a learn button push that and a red LED will come start flashing press and hold the button on your remote until the LED stops flashing (solid red) press the button on your remote again and the light will go off. This will program a remote

Door will go down only if i keep button pressed


This is what we call in the buisness a constant hold down , that means that the sensors are not aligned , be careful when checking theese sensors because even the slightest flicker will send a false signal to the opener and not allow it to come down , I have installed over 27 thousand ..yes thousand machines to date and i,ve seen it all also make shure the sensor lenses are free of dirt or cobwebs , so now you need to check theese things and also if you realign the sensor and you only have to do one ! make shure you have a steady solid light, is their is a short in the wire ,you should splice a new wire in its place black to black and white to white as they are color coded universaly, also check for brooms and shovels and the typical junk that people usually put in the corners of the garage ,i,ve had many service calls and just had to move a broom that was in the way of the sensor , the beam must be unobstructed and the lights should be bright and solid without any flicker , also green light is the sending unit and the yellow light means it,s the recieving unit on your sensors , Hope you have luck and i was able to help you ,thanks so much for the questionSincerely glenn

the problem is with the sensor at the bottom of the railing. We had to replace the photosensor on one of them.
