Tighten the Condenser Fan Mounting Bracket

A loose mounting bracket can cause the condenser fan motor to vibrate against the refrigerator chassis, creating a rattling noise. To fix this, unplug the power cord and move the unit away from the wall. Remove the rear access panel to expose the fan motor assembly. Check the mounting screws or clips securing the fan to the bracket or cabinet. Use a screwdriver to tighten any loose fasteners until the motor is held firmly in place. Verify the fan blades do not touch any surrounding components, then reattach the cover and restore power.
