Looseness
Check a loose fan assembly for wear. Replace a worn assembly as necessary. Under various temperatures, there is a visible lateral movement at the tip of
the fan blade. Allow approximately 6.5 mm (1/4 inch) maximum lateral movement measured at the fan tip. More movement, is cause for replacement.
