Tilt your fridge backwards slightly. Gravity will close its door if it isn't open too far.
Clean out the fridge so stuff inside doesn't block the door.
Don't keep your dog nor pet alligator in the fridge. ;D

Seriously, if you power the circuit from 6V, you could replace the buzzer with a 5V relay's coil with a flyback-arresting reversed diode. The relay contacts can drive the motor.
