Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care FF Error Fix: Freezer Fan Failure

The freezer evaporator fan is not running — this fan circulates cold air from the evaporator throughout the freezer compartment; without it, the freezer temperature rises and food thaws; check the fan motor for continuity; check the fan blade for ice buildup or mechanical obstructions preventing rotation; the fan normally stops when the freezer door is opened (door switch controlled) so testing requires bypassing the door switch temporarily; a seized fan motor (won't turn by hand) must be replaced
