Limit Switch

What would stop both my genie promax 500 door openers from closing on both machines at the same time? They both start to go down and then reverse. Seems strange they would both get this issue at the same time, like it’s another outside influence. I’ve done everything in the manual and on line to troubleshoot without luck. ☹️

This sounds like the safe-t-beams could be interfering with each other. Try changing the safe-t-beams on one of the garage door openers. Just switch the red and green safe-t-beam. You can also contact Genie customer service at 1-800-354-3643 for assistance.

I have the Genie Pro Max. When the full sun hits the left sensor (see from inside) the inside control box or the remote used from the car will not work. At times I can block the sun with a cardboard and the remote will work. When the sun is off the sensor that is at the base of the track it works like new. I am using a new battery. What would you suggest? Thank you!!!!

I would recommend switching the safe-t-beams. So move the left one over to where the right one is, and right to left. You can leave the wires, just move the safe-t-beam itself.
