How can I fix the ice crusher on my Samsung RS21FCNS side by side fridge fr?

I assume that you have removed the ice unit. Behind that is the drive to the unit, behind that will be the motor, BUT is the unit delivering ice. I assume it is, So motor working, Ice crushing, is done in front of ice unit. A flap in the front of ice unit, opens and closes, open, cubes, closed ice will be crushed, They are allowed to drop though, Or not. operated by lever which runs to back of ice unit, operated by a unit next to motor coupling, IF ice unit lever not stuck, look n back of unit, possible solenoid fault, could be control etc, you will need test meter to check.
