There are limit switch that have to work, so if it is moving with sound, but the door doesn't open it may be a simple limit switch adjustment.
Or the door motor failed.
The previous repairs I have made have been faulty drive motor for the car that damages the board.
I do have spare parts for it. MTH sells the motors and or the whole gear box assembly with motor. Just requires Medium to high skill level for disassembly and repair, and recording where all the plugs attach to the circuit board. G
