Will not defrost

The replacement part went in quite easily and quickly. The instructions sent with the part was pretty self explanatory. I have also replaced the defroster element, the defrost thermostat and now the main control board. After having done all this the thing is still freezing up. After disassembling the whole freezer section I found yet another temperature sensor (Also known as Thermistor). I'll replace this part next and if it still freezes up you'll be able to find it sitting on the curb. Thrown enough money at this ten year old fridge and a new one will be in order. Thanks Parts Select for reasonably priced parts, the posts to help with the repair and the fast shipping.
