The evaporator, evaporator fan, defrost heater and defrost thermostat are located behind the evaporator assembly cover. The cover is removed from the front on the inside of the freezer compartment.
Once the cover is removed you can see the fan and check if it operates by manually operating the door switch which should turn off the light and turn on the fan with the door open
The link I posted earlier has the parts locations diagrams see Cabinet parts #1104 for the cover, part #724 for the fan, #880 for the defrost heater and #771 for the defrost thermostat I think that that is it even though it is called thermal insurance but it looks like it.
If the fan and evap unit is iced over i.e. fan does not operate, then the freezer will still be cold because the evap unit is freezing cold (-18 deg C) from the refrigerant that flows through it and it is located in the freezer compartment. The refrigerator will be warmer than it should be because no cold air is being blown into it by the fan.
Disconnect the power from the fridge and use an Ohmmeter to check the defrost heater. Normally it should test 20-50 Ohms. If it is OK check the fan motor. If both OK check the drain hole tube.

The drain hole is located below the evap unit and drains the melt water to the evap pan under the fridge . If it is blocked then the water can't drain away during the defrost cycle, and it will refreeze and build up until it covers everything and stops the fan etc. Pour a measured amount of water down the drain hole (not too much) and check that it all gets to the evaporator pan under the fridge

The drain hole is located below the evap unit and during the auto defrost cycle, drains the melt water to the evap pan under the fridge . If it is blocked then the water can't drain away during the defrost cycle, and it will refreeze and build up until it covers everything and stops the fan etc. Pour a measured amount of water down the drain hole (not too much) and check that it all gets to the evaporator pan under the fridge
Avoid using a hair dryer on high heat to melt the ice on the evap unit etc as this can damage the evap unit and also the freezer liner which is very thin and cannot be replaced. You can use it on the coolest setting for short periods just to help it along a bit but don’t leave it on the evap unit for too long. You just have to let it melt by leaving the door open and the power off of course
