Our 48" Built-In KitchenAid Frig (1999 model)started getting very noisy about 3 years ago. Two different repairmen plus KitchenAid said 'that was the way it was'. I figured out the noise was coming from the evaporator motor/fan but the repairmen said it was just because moisture was freezing on it and replacing the evaporator motor/fan probably would not make a difference plus it would be very expensive. When I discovered PartSelect and that I could order the parts (about $80) myself I thought why not. It was simple to replace. Removed cover inside freezer compartment - detached bracket and electrical wires - replaced with new motor and fan. Now you can hardly hear the frig running and it runs half the time - more efficient. I can't believe we lived with that noise for so long. Thanks to PartSelect I proved KitchenAid and the repaiirmen wrong and did it myself! Thank you PartSelect!

Removed Freezer drawers.

Reinstalled back plate and out all 4 screws back in.

Plugged fridge back in and new fan motor was working, and there was an immediate difference in the temp in fridge.

about half my time was spent figuring out how drawer front and back panel were held in:
remove wire baskets
lift freezer drawer front to remove
remove ice maker...held in by 3 screws,then unplug
remove back panel screws
then on this model, there is a vent towards the top of the panel that is held in by unseen plastic clips on the top left and top right that had to be pressed in with a screwdriver to remove
unplug freezer evap motor also held together by clips
remove and replace motor (old fan blade pulls off and slides on new motor shaft)
plug motor back in
reinstall back panel

reinstall drawer front and baskets
