Changing refrigerator cooling unit...New or Refurbished??

I have decided that most likely the cooling unit is bad.

I ordered a new Amish built cooling unit that will arrive in about a week. Since I'm going through all the hassle and have the fridge out and take apart, I will also replace the heating element (~$35) and the thermistor (~$25).

I'll let you know how it goes once I receive everything and get it all back together.

Thanks all for the help!
