ARNU153SER2 (ANCALUS) LG Air Conditioner - Overview

The inside air blower for the LG mini-split collects lint and clogs up. Removing the broken blade requires removing the outer plastic housings, then screws at each end of the blower housing. Some screws at the control end require removing the control units first. There is a set screw that connects the fan to the motor shaft at the control ... Read more end. There is a missing blade in the fan to allow access. This screw was lock-tighted in place and required significant force to loosen. The new fan took some wiggling to get it onto the shaft. Then replace the screws at each end of the fan housing, followed by the control unit screws, and the plastic outer covers. It was not an easy job. I used more care with a small bottle brush to clean the second fan unit and avoided breaking that fan.

Ordered replacement part from Part Select. Part verified thru LG customer service. LG stated that connector on Part Select Thermistor assembly won't match the connector in the LG unit. Cut the connector from the defective Thermistor and spliced it into the Thermistor from Part Select. Unit works fine after repair.
