Refrigerator vibrates excessively or moves when the door is opened or closed.

Safety first: Be careful when tilting or moving the refrigerator to avoid tipping.

Steps:

• Adjust leveling feet: Use a wrench to extend the front leveling feet until they firmly contact the floor and slightly lift the front wheels.
• Check side clearance: Ensure the sides of the refrigerator are not pressed tightly against cabinets or walls.
• Stabilize rear: If the rear wheels are adjustable, set them so the unit is stable and does not rock.
• Recheck door operation: Open and close doors to confirm the unit no longer moves or vibrates excessively.
