This means the sensors are not aligned and need to be adjusted. Slowly move one side very slightly and watch for the light to come on.
Don't get to crazy with the adjustment it's probably just a slight amount of movement will do it
Watch for the LED light to come on. If it doesn't come on carefully check the wires all the way from the sensor to the controller for a staple pinching it or stuck through it.
I've done it. Played with it for over an hour. Even took it off the bracket, cleaned the lenses, and made sure the wires weren't shorted on any staples. The light in the sensor would never come on fully like the other.
Look at above post
Have you checked for a staple in the wire?
Check the connections in the wire nuts
Pull on the wires
Check at the controller too
check the screws on the wires
Above post? I traveled the entire length of the wires and checked the connection on the motor unit.. No wire nuts on this.
none at the sensor?
What about the terminals where the wires leave the controller
Did you check the screws?
The sensor usually has two wire nuts to connect it
wiggle the wires, they can break at the terminals or wire nuts
No, none. Bell wire runs as a solid strand the whole distance. No splices or anything. Checked right at the controller. Even unscrewed the connection, check my wires and tightened down again. I suspect wire is broken inside the rubber grommet on the plastic housing. Not a complete break, just enough to fowl up the sensor and mess up operation
Is the light on at all, dim?
It will come on dimly for just a second. I then go to the wall switch to open and close as a test. Opens of course but then the problem repeats when I try to close. Go back to the sensor and the light is out.
Is there a red blinking light on the controller? How many times does it blink in a row?
Where would the red blinking light be. On the same side as the SRT button? I haven't seen one.
On the back of the controller
there is a fault code, one, two, three blinks all tell a fault
Let me go look. Will it be on now with the door closed?
Will it be under the motor housing cover?
Not sure, try to open and see if you get a red blinking light. It will be in plain sight
on the back
near the learn button
Yea, red blinking lights are funny that way. Very obvious. :-) Just a sec.
Only light is the green on flashing near the SRT button. Is there a reset button anywhere?
K. I've got a big baseball bat, will that fix it?
the green is flashing?
Go to the manual and see what the light blinking is, how many blinks then a pause then more blinks?
This usually means a fault of some kind
Looks like a constant intermittent blinking.
Its called the indicator light. Used to signify when codes are "learned." Looking for anything else.
Has it always blinked like this?
Do you recall?
I seemed to remember it doing it. I changed vehicles recently (3 months ago) and it was doing that when I went to change codes. Not seeing anything else.
Go up near the motor and there is a 'RPM sensor' make sure it's plugged in tight
Where would that be?
Found the diagram.
I had that unplugged a few months ago when I changed the drive/worm gear. Give me a few minutes.
give things a good clode look
Got in there and all seems properly connected. Unplugged the drive unit and then plugged back. Went to the sensor and did the wiggle adjustment to see if it would light. Nothing.
I think I'm gonna have to bite the bullet and buy new sensors.
It's a good possibility...
Is there any way you could get one sensor over to the other for a close aligment?
How cheap can I be. I bought the thing 15 years ago. The worm drive was the first thing to go and that happened in October..
I thought of that but used a laser pointer to make sure they were lined up. The darn little green light on just one side will not go on.
Already there. $39.49. Anything else?
could be a bad sensor
hope that gets you going
k, thanks. You confirmed what all my steps. Good thing is Sears Parts is a block from the office. Of course, if it snows here in San Antonio tonight the whole city will be paralyzed.
Very cold here, 5 degrees now
-10 this morning!
