I'm assuming the sending sensor is the one on the right looking out of the garage. If so, that one is steady amber or yellow. The sensor on the left is green and goes out when I break the beam. That tells me it is receiving a signal from the sensor on the right. I have realigned the sensors and still get the same problem. I have checked the wiring and it is not loose.
Upon further testing, it doesn't always stop and reverse. Three out of 4 times, it will stop and on the fourth try go all the way down. I did this several times.
Well I tested the voltage and here's what I got:
Sensors connected: 5.93 V
Sensors disconnected: 6.23 V
So, I don't know if it's the sensors. I did adjust the force downward button up one number from 5 to 6. Now the doors go down all the time.
I read up on that and it says that sometimes weather can cause this issue. I'm in the Denver Metro area and we've been saturated with rain since Wednesday and this problem started on Thursday. Coincidence?
I had a technician come out 2 years to replace my springs and he said everything else looked good. The system is 13 yrs old. Is it time to replace the sensors for due diligence?
Thanks for your help on this and awaiting your response.
