Condenser Fan
Adding a bit of FYI. I found a similar unit a few years ago, except that it was the ice maker/refrig combo. The ice maker is in the location of the freezer in the unit you have.
The condenser fan motor on mine was totally bound up, and since there was no cooling of the coil the unit ran hot. Cleaned and oiled the motor and the unit now runs perfectly. I use it when I have a need for extra ice.
