LG LT121CSG Fan Motor
The vast majority of fan motors of wall units can be really simple to swap out assuming you have home improvement skills and some understanding of simple mechanics. The fan motor turns the blade which is the reason for the heated or cooled air moving into areas of the house.

- You can sometimes hear grinding or other unfriendly noises when the unit is turned on
- The fan blade stands still when the system should be creating an airflow
