I have a friend who has a Genie garage door opener. It is about 3 years old and is one of the screw type drives. Just the other day when we tried to open the door it rose about 18 inches and then stopped. We closed it and tried again. This time it rose to about 24 inches. This went on for 8 tries before the door finally opened. I then opened and closed it a couple of times and it seemed to be ok. But later on when we came home, the door would only open 18 inches and no matter how many times we tried it would open no more. We pulled the rope to open it manually and it went up with no problem. So we engaged the trolley and tried the remote again but the door would only open a foot or so.
Any advise as to what to try next ? Does this soundlike the motor is going ? Help ...!
