LW2512ER (UWC253TDMK5) LG Air Conditioner - Overview

Pull the unit out of cabinet. Remove the brace between the blower housing and the condenser frame. Remove the screws securing the the condenser coil to the base and carefully lift and angle it just enough for the broken fan to clear ( be very careful with the refrigerant lines ). Slide the new fan back on the shaft and secure with the spring clamp. I used a pair of vice grips to compress the clamp, but be very careful because the clamp can exit the pliers, if the jaws are not perpendicular to the clamp. If you live in a area with high humidity remove the rubber plug at the back of the unit or the condensation will break your new fan. This fan needs some changes in design because the condensation puts too much stress on the plastic that contacts the motor shaft - some metal between shaft and the blades would help.

Part of the fan blade broke on my AC unit and was causing a vibration. This made the AC unusable. The ordered Fan was a perfect OE replacement. I simply removed the outside over and then the fan shroud inside the unit. I carefully repositioned the condenser unit being careful not to damage the fins. Using a pair of pliers, I removed the retainer clip and removed the old fan. The new fan slid right over the shaft. I replaced the retaining clip and then repositioned the shroud. Then I placed the condenser and fins back into place and then placed the cover back over the unit. Worked perfect. No issues. Take your time. Excellent replacement fan!
