Question about Refrigerators
Remove back of unit and check defrost heater has not become detached, otherwse the is only two possibilities, one a defrost fault and although you say the defrost tube is clear the only reason it does not flow is due to a restriction, what can happen is that the water backs up the drain pipe and then freezes before the water in the external tray can evaporate.

The fan stops during the whole defrost cycle, there is a bi metal control that determines the length of time the heater stays on. This could be the problem, if the heater stays on for the time that is allowed by the defrost timer it will get too warm in the freezer. the bi metal is located on the evaporator.

With you model and brand I would want to check the voltage on the fan and shaft play. Meaning the fan may be going bad or the voltage being altered at the motherboard. I do know your model with the control board that it has if a fan becomes defective the board is also affected. If the fan goes bad and replaced it is very possible that the board will fail and cause the new fan to fail. If you need help with diagnostics please let me know, Thanks, Sea breeze

Since you say that is isn't cooling
properly, I would first start off by cleaning the condenser grill
that is located under the cabinet. While this won't correct your
problem entirely, it will help!
Most likely you have a defrost system malfuntion. The defrost system consists of the defrost heater (p/n: 5303918208) which is the long tube like thing that sits directly below your evaporator behind the panel in the back of the freezer (inside the freezer). It also consists of the defrost thermostat (p/n: 5303918202), which is located next to the evaporator. Both the defrost heater and defrost thermostat can be checked with an ohm meter - a non-open/infinity reading is good. If both of those check out and are good then it has to be the defrost timer (p/n: 215846602) which is located behind the plastic shield (with the light bulb).
Suggest you defrost the unit (making sure no ice or frost is behind the freezer panel then plug the refrigerator back in. If everything cools down then my diagnosis is correct and one of the components of the defrost system is bad.
