a). Given that blowing on the evap fan in the freezer (I assume this is the one you meant) starts the condenser fan and the compressor working it could be that there's a problem with the temp control thermostat.
When there's no cooling at all i.e. no compressor or fans, try adjusting the temperature control knob so that the desired temp is colder and see if the compressor and fans start to work. It may be that IF the thermostat is faulty that it "thinks" that is is cold enough inside the compartments so it turns the compressor and fans off.
-
What should happen then is when the compartments warms up again due to normal activity e.g. doors open etc the temp control should then turn on the compressor and fans to keep the temperature between the pre-set upper and lower temp limits. Basically it cycles the compressor/fans on and off as required.

Perhaps by forcing the temp to rise by blowing on the fan you are increasing the temperature in the compartments to a point where the thermostat does respond
-
If adjusting the temp control does start it again and if the it stops again after some hours and doesn't start again except if you touch the temp control, this sort of points to it being the problem.

If you decide that it is the problem here's a [https://www.youtube.com/watch?v=cnL65Kg3iHw|video] for how to replace it. The part number for the thermostat is shown in the video i.e. W11088945. Search online for the part number to find suppliers that suit you best. There's an alternate part number as well WP2315562 if you can find the first one.

b). If the thermostat is OK then it may be a wiring problem e.g. loose connection perhaps in the operate path for all 3.

b). If the thermostat is OK then it may be a wiring problem e.g. loose connection perhaps in the operate path for all 3 i.e. compressor, condenser fan and evaporator fan.
Looking at the wiring diagram in the [document|32714|tech sheet][ for the refrigerator, the evap fan, compressor and condenser fan all operate in parallel via the temp control thermostat to receive power from the electronic defrost control board, terminal P5.
If you follow the circuit the Neutral is behind each of the components (white wire on right side of each in the diagram) and then they are all joined to go to the temp control thermostat on a red wire, through the thermostat to the board.
Given that the evap fan is in the freezer it may be that that is the point where they're all joined as it may be the closest point to the thermostat control as far as the wiring run is concerned.
This is only speculation on my part but it may be that you will have to remove the panel at the back of the freezer compartment (access through the door at the front) and then check the fan's harness wiring connector.
Perhaps the only other thing is to check if the defrost control circuit is working by using the defrost test procedure as outlined on p.1 of the tech sheet.
If all the above seem OK then it may be a defrost control board issue.
Seems strange that using a blower on the evaporator fan can cause the compressor and condenser fan to operate.

Couple of things to check perhaps.
