Step 1: The ice machine should be disconnected from the electrical outlet and the water supply should be shut off.
Step 2: The ice machine's access panel should be removed and the screw tuflock, which is situated at the rear of the unit, should be identified.
Step 3: With a Phillips head screwdriver or the correctly sized socket wrench, the screw tuflock should be loosened until it becomes free for removal.
Step 4: The new screw tuflock should be placed into the opening, ensuring the holes in the tuflock align with the threaded holes in the ice machine.
Step 5: The screw tuflock should be securely tightened until it is firmly in position.
Step 6: The access panel should be replaced and the ice machine should be reconnected to the power source and water supply.
