Approaching the hot weather of summer 2010 has Decided to repair the air conditioner yourself. Getting to the restoration of the conditioning, it was first necessary to remove with a damp cloth the dust and possible contamination on the air conditioner. Remove the rear wall by unscrewing the 6 screws. Gently remove the fan cover without damaging the locking seal of the lid. Inspect the fan wheel. In my case it was just sitting in the housing with a ruined place of mounting on the motor axis. Remove the fan wheel. Thoroughly remove all chips of plastic from the base of the fan. Remove the bushing securing the wheel with the axis of the motor by unscrewing the retaining nut. To further test the fan motor, taking care to turn on the AC in the network. If the motor works, as in my case, disable the fan after removing the mains plug from the socket. To begin the inspection of the damaged area of the fan wheel.
