Turn off power, remove upper and lower drawers (may need to open upper refrigerator doors to remove large freezer bin,) remove drawer supports (upper and lower), remove rear freezer panel (trick is to loosen 4 screws on fan bumpout to get the panel to come free from the freezer side wall), test thermistor with multimeter (should have continuity or near zero resistance across 2 orange fuse wires) before cutting zip ties, cut zip ties holding Thermistor in place, remove old Thermistor, install new Thermistor, install new zip ties, replace rear freezer panel, install upper and lower drawer supports, install drawers, turn on power, should be fixed if error code doesn't return after 6 hours.
The Refrigerator now runs very quite. After watching several videos I started on mine and found that it was a bit different than any in the videos. However all but the back panel was shown and that was helpful. The back panel was a bit difficult but a hair dryer seemed to help . All in all it was a good choice to do it myself as it was done quicker than waiting on a repair man.
