Ryan S Gainesville , FL January 03, 2018 Fan on mini split air handler indoor unit went bad (making squeaking sound) Ordered part # 4681A20091U for LG mini split. Had to disassemble the indoor coil with screw driver and gently pull the coil forward until I could get the fan & motor assembly free. The new motor plug to the circuit board had a slot in it that wasn't on the old motor plug so it wouldn't fit in the control board. But I simply shaved off the slot and made sure the plug was oriented the same and it then fit. Reassembled and everything is working great and no squeak!
