I bought a new Genie screw drive garage door opener last summer and
installed it with my friend's help. It was working fine until a few
days back it would come all the way down until the LED sensors and
then would go back up. When the door reaches the LED level, the LEDs
would blick a few times and then the door would go back up. I have
tried adjusting the limit switch positions and the "open" and "close"
screw on the panel head. I have also checked the levels of the LED
alingment and also cleaned the LED lens with no luck. One thing I
notice is that when the door is closing and if I try to hold the door
manually with my hand to check the pressure, the door does not stop.
It goes all the way until the LED level and then goes back up. I have
also checked the wiring for the LED. Any idea where the problem is???

My guess is the door, or something on the door is breaking the light
beam. Is there maybe a loose tag or string or something? It is also
possible that the sensors are vibrating and if track mounted the track may
be twisting as it gets to that point.

Joe,

I did get a new sensor and it did not fix the problem. I will check
for any vibration in the mount as you suggested.

Hi,
Stray sunlight, shadow interfering with the sensor?

I changed the red one to green with no luck. Do you need direct
sunlight? How does it work during the night? Let me know.

Hi,
That beam of light emitted is usually Infra-red. Usually invisible.
You can measure the output of sensor with digital multimeter blocking
and unblocking the beam of light. You should notice different meter
reading between two. My opener is also Genie screw driver but this was
installed before the days of mandatory beam sensor.

What he meant is "is sunlight blinding the sensor?" This can happen when
the sun is shining directly into one of the two sensors - they don't have
enough power to overcome the brightness of the Sun.

Also, the two sensors are not the same though they may look the same. One is
a transmitter and the other is a receiver. Did you happen to install two of
the same kind? If so, that will cause a problem.
