How do you tighten fan for the air conditioner?

To tighten the fan for an air conditioner, first, turn off the power to the unit to ensure safety. Remove the front panel or grille to access the fan assembly. Locate the fan blade and check for any screws or bolts that may have loosened; use a screwdriver or wrench to tighten them securely. Finally, reassemble the unit and restore power to test the fan operation.
