tC — TurboCool active (not a fault)

TurboCool is engaged — the fresh-food compartment is intentionally running at maximum cooling for about 8 hours to recover from a big grocery load or door left open. Not an error.

Keep using it?: Yes — fix when convenient

How to fix it

Press the TurboCool button again to cancel — display will return to normal temp.
Let the unit normalize over 4–6 hours.
If tC re-engages on its own, inspect the dispenser membrane pad for a stuck button or moisture intrusion.
Replace the dispenser control panel if a button is permanently shorted.

Replace your water filter

A clogged or overdue water filter is a common cause of low water and ice flow on GE refrigerators — they are meant to be changed about every 6 months. The OEM-style filter that fits most GE refrigerators is the XWF ($45-55 OEM, $18-28 compatible).
