You say that you have replaced the defrost heater and defrost thermostat, which defrost thermostat did you replace, there is just one defrost thermostat, its not the one looks like the typical defrost thermostat, its the white colored one about the thickness of a pencil attached to the evaporator with a 1 inch long clip, its the same as the temp. sensors, what looks like a normal defrost thermostat is a high temp safety in case all else fails to shut the heater off.

I have seen thes fail quite often, there resistance change when it fails and basically will cause the board to think its already defrosted by sending a temp thats above the defrost cycle terminating temp,thus prevents the heater from coming on.

This defrost thermostat will also look like the one of the sensor near the floor of the freezer. About a inch and a quarter long / about a 1/4" thick all white plastic with two white wire comming out the back...............................good luck.
