    Both eyes are green. Not one red & one green. Any ideas? I’m thinking old eyes were left from previous opener? Help!

    Drew,

    That could be a possibility.  If your photo-eyes do not look like the photo-eyes on this link https://www.dropbox.com/s/and4hy1tif0z7ww/PhotoEye_white%20background_150402.jpg?dl=0 it would be the case.  Replace the photo-eyes immediately with Guardian photo-eyes GUAT-201.  The old photo-eyes will not be dependable and may not reverse the operator when the IR beam is broken. 

     Call 424-272-6998 to troubleshoot further.

    Hi Lee,

    1. Most photo-eye (PE) issues are due to mis-alignment.  Loosen the wing nuts on the PEs and make adjustments until steady green and red LEDs can be see.  If this does not work, follow the process on the linked file to determine the source of the problem.

    2. Staples will often, over time, cut through bell wires causing shorts and system malfuntion.  Materials will expand and contract with changing temperature, humidity and other environmental conditions, so an issue like this tends to happen more in the winter and summer.  Bell wire sould be replaced.

    3. Your door can be closed by the operator by pressing and holding the push button control.  This is a line-of-sight overide in case the PEs malfunction.  All garage door openers have this function.  

    Follow the steps in the troubleshooting guide to isolate and solve the issue.  If you have additional questions, please call a professional garage door opener technician or 424-272-6998.

    I found my manual and it states door travels at abnomal speed for the 12 slow beeps but it doesn't say how to fix this issue. I also tried moving the door with the up/down limit set approach. The belt will move up but not down. hmmm...

    Mike,

    The issue you describe is often related to a stuck relay.  With the handle of a screwdrive, giive the back panel where the buttons are located a couple of firm taps.  This could free the relay.  If this does not work, call tech service 424-272-6998 for more assidtance

    The green photo eye blinks and is not solid. The red led has a weak glow. There’s no obstruction and I can’t seem to align the photo eyes. If I put the photo eyes closer, the red eye has a better solid. Do I need new photo eyes?

    Hi Edward,

    1. Please be sure that all 4 wires for the photo-eyes have been inserted into separate terminals (in the terminal block in the motorhead).  Low current to the photo-eye causle be causing the green LED to flash.

    2. There may be a chance that PE circuitry was damaged by a power surge causing the green LED to flash.  (PE would need to be replaced)

    2. Call tech service (424-272-6998) for additional help.  Please have the model and serial number of your operator when you call.
