Symptoms

  • Er IF or F1 on display
  • Ice maker stops dispensing

Rare; fan drive circuit failed.

How to Fix It

  1. Defrost the ice compartment for 8+ hours with doors open.
  2. Check the ice room door gasket for gaps; reseat or replace.
  3. Spin the ice-room fan by hand — replace motor if it doesn't turn freely.
  4. Reseat the fan harness at the main board.
