Fan Noise

Normal fan noise is sometimes evident when the clutch is engaged for maximum cooling. Fan noise may also be evident during the first few minutes after cold (overnight) start-up. This noise will continue until the clutch can redistribute the silicone fluid back to its normal disengaged operation condition.

Fan clutch replacement is required if fan noise or excessive roar occurs continuously or if fan cannot be rotated by hand. If a roughness is felt as fan is turned by hand, unit must be replaced.
