Refrigerator makes loud humming or buzzing noise from rear

Safety first: Unplug the refrigerator before working at the rear.

Steps:

• 1. Pull unit away from wall: Ensure there is adequate clearance and that the cabinet is not touching the wall or cabinets, which can amplify vibration.
• 2. Remove rear cover: Access the condenser fan area.
• 3. Inspect fan blades: Remove any dust, plastic, or wiring that may be contacting the blades.
• 4. Check fan mounting: Tighten any loose screws or brackets holding the fan motor.
• 5. Spin test: Rotate the fan by hand. If it feels rough or wobbly, the motor bearings are likely worn.
• 6. Replace condenser fan motor: Install the correct V-ZUG condenser fan motor and reassemble.

Warning: Do not operate the refrigerator with the rear cover removed for extended periods; proper airflow is required for safe operation.
