Garage door all kinds of problems
Worked great until we were required by code to sheetrock our garage...
Now it wont go down without you holding the button that normally you touch once and the door opens or closes. Release button and it reverses with flashing light. Seems to me that by holding the button we are perhaps overriding a safety switch
I now have one sensor that flickers. Even when realigned it flickers.
Guessing that the sensor has gone bad.
