Determined that the evaporator fan in the freezer compartment was not running properly and making noise. Ordered a replacement evaporator fan and blade. Removed the freezer door, baskets, and side rails. Removed the back panel of the freezer compartment by unscrewing and disconnecting the power cable connected to the fan. Removed fan blade. Turned over the panel and removed the back fan bracket and fan. Installed replacement fan, back fan bracket, and fan blade. The grommets ordered were the incorrect part for this fan so I did leave the existing grommets in place. Reattached fan cable to power cable in the back of the freezer compartment and inserted panel. Re-installed the rails, and freezer door, then baskets. Pl PB975SM2SS
