How to replace bushing in lg heat pump

Hi @bib70113

Looking at an image of the parts for the indoor unit (see below) it may be that there are two bearings for the fan unit. One at the far end of the fan scroll assembly and one in the fan motor, although I'm not quite sure that there is replaceable bearing in the fan motor as there isn't one shown as a separate part of the fan motor in the diagram.

Part ID #342800 (green arrow - LG part number 4280A20004M (examples) is at one end of the fan scroll assembly and there may be a replaceable bearing in the fan motor (part ID #346810 red arrow - LG part # EAU62004010 (examples only)

I couldn't find a video that shows how to disassemble and access the fan motor in your model but here's a link that has a lot of videos that in general show how to replace the bearing in the fan motor but not one at the other end of the fan scroll assembly.

Hopefully it is the bearing at the other end of the fan scroll assembly that is the problem and not the one in the fan motor because it isn't listed as a separate part.

Here's the service manual but it only shows the specifications, the flow diagrams, the wiring diagrams and the parts layout for the indoor and outdoor units but not how to remove/replace any parts unfortunately.
