On my 2014 FC 20, when you lift the upper vent you can see the fan and the wires which go to it. One of them goes to a little round device with ears on it. That is screwed to one of the fins on the upper right side of the uppermost coils on the unit. On mine, that is the thermostat. Mine also has a switch with light on it inside, so the fan can be turned on and off manually, assuming the thermostat says it is warm enough.
Now, your 23 may be different, and I understand that not all rigs with a fan had a switch inside to turn it on and off.
