Error code1C1C
ApplianceRefrigerator
Affected model seriesKitchenAid refrigerators, laundry, cooking, and dishwashing controls that show service codes
Quick answer
1C1C on KitchenAid refrigerator appliances often means Refrigerator control code.
Model compatibility: KitchenAid reuses codes across series and model years, so 1C1C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Seeing 1C1C? On many KitchenAid refrigerators that readout maps to refrigerator control code. Record freezer vs fresh-food temperatures before you book Artisan Repair. Two KitchenAid units can share a display string yet mean different subsystems; verify the definition for your serial family.
