Fridge not cooling

The fridge wasnt cooling and freezer was barely operating. We had the same problem in 2005 and the fan that blows cold air into the freezer and fridge was replaced for $200 BY Maytag. We looked up the part and found two choices with different connectors but narrowed it down by the pictures and series #. The part was ordered Sunday and arrived Tuesday for ~80$. To intsall you simply remove food and shelves then 4 nuts that hold back pnael in place. Then release one wiring harness connector to allow the panel to pivot out. After that you can easily release the clips holing the fan cover and then undo two screws to drop assembly out. Two more screw release fan body (you can reuse the fan blade) and one more for the earthstrap. After that follow reverse instructions to reassemble and after ~45 mins the unit was as good a new. Having said that there seems to be a basic design flaw in this maytag unit if fans only last 3-4 years. Still much cheaper than buying a new fridge.
