crafts man garage door opener won't go down at all
hey guys, really need help with this one. A friend of mind trying to figure out why her door goes up but not down. I went and tried to help her but didn't help much. I try all the nobs on the back and try to turn it slightly and continue doing so and it still wasn't going down. it make the noise that the motor whats to work but nothing is happening. Does this means that the motor is lock on one direction which is up only?..
