It sounds like the freezer is not defrosting.
This would indicate a problem with one of the following:
1. The defrost timer.
2. The defrost heater.
3. The defrost thermostat.
Locate the defrost timer in the front right corner behind the kick plate.
With the compressor running turn the knob until the compressor shuts off.
The fridge will now be in the defrost cycle.
If the heater comes on and melts the frost you have a problem with the defrost timer.
If the frost does not melt then there is a problem with the heater or the thermostat.
You will need a meter to check the heater and thermostat.
The thermostat can only be tested when it is at operating temperature.
