I have confirmed that the transformer works fine, it outputs 24V

The motor vibrates when I apply 24V to it, but the pinion is locked, it does not turn (probably it is by design to lock the garage door)

Consequently, I believe it is the circuit board that has failed. It does not send signal to the motor.

Is this something that can be fixed? Should I send it somewhere for repair? If so, where?


Also, am I right in assuming that the pinion is locked by design? If so, does the circuit board send it some kind of signal to unlock it?
