OK, It's not making logical sense here.
Fault 1 - Hot between the doors.
The transom between fridge and freezer gets hot when the condenser is blocked or the fan doesn't run.
You've replaced the fan, have you cleaned out the fluff from the condenser?
(Take the grill below the doors off to access the front of the condenser and the rear panel to access the rear of it).
Does the fan run now?
Fault 2 - Water dripping inside the freezer.
Have you switched off the ice maker?
If not, switch it off, does it stop the dripping water?
If water comes out of the water dispenser every few hours, what happens when you press the lever for a glass of water? Does it flood the freezer?
If yes, you have the pipes on the valves reversed.
Did you have them disconnected at the valve to replace the fan?
If yes, take them off and swap them over.
It's not going to be an electrical connection unless you physically removed the wiring to the valves, swapped them over and plugged them on again.
The double dashes in the display indicate the temperature in the freezer compartment is too high.
It will alarm until the temperature gets down to something like -13 degrees C inside the freezer compartment.
Let me know what you find.
