GE Refrigerator AF — Air filter replacement reminder

GE Refrigerator · Error code AF

What AF Means

The interior FreshFlow air filter timer has expired (about 6 months). Carbon air filter should be replaced and the timer reset. Cooling is unaffected.

Symptoms

  • AF or 'Air' icon on display
  • Stale odor in fresh-food compartment
  • Light indicator on filter cover lit

Common Causes

1
6-month air filter timer expired

Timer counts down regardless of actual filter condition.

2
Filter never replaced after unit purchase

Common on used units — owners don't realize an air filter exists.

How to Fix It

  1. Open the FreshFlow air filter housing (top rear of fresh-food compartment).
  2. Replace with a genuine GE Odor Filter (Cafe Profile FreshFlow).
  3. Press and hold the 'Reset Filter' button 3 seconds until the AF clears.
