Possible Causes

Open/shorted fresh food thermistor, Loose connector at control, Damaged sensor wiring

Safety first: Unplug the refrigerator before accessing sensors or control boards.

Locate fresh food thermistor: Typically behind a small plastic cover on the refrigerator wall or near the air damper.
Inspect and test: Check for physical damage, then disconnect and measure resistance. Compare to spec; replace if out of range.
Check harness: Ensure the harness from the thermistor to the control board is intact and fully seated.
Replace sensor: Install a new thermistor if faulty, route wiring as original, and restore power to confirm F1 clears.
