The problem started when my wife locked the door handles on the garage door thinking she was opening it when locked out. Not knowing, I came home and tried to put the doors up by the remote, but they were locked with the manual locking bar. The security bar bent, and the doors stopped. After finally getting the bar unlatched and straightened, now one of my doors won't stay down. Both wouldn't at first. I have opened/closed it manually and the track seems fine. I realigned the sensors until they were lit and not blinking at all, yet the base blinks when it returns to the up position after not closing. Any ideas??? I've tried all the usual culprits and solutions carefully.
