I have Genie ISD990 that has been giving me me intermittent problems closing the door. I grew tired of manipulating the wires on the push in connectors of the safe t beam sensors, so I bought new ones. These have screws to hold the wires. After installing them both beam lights were on solid but, I am unable to close the door. I get 5 blinks from red led light on the control head and I have tried closing with both remote and using wall control. I tried everything I could think of, so I put the old sensors back on and they work correctly. I would like to use the new sensors if I can.
Thanks for any help
