KitchenAid Refrigerator 1C4C Error Code
If your KitchenAid refrigerator shows 1C4C, start with the safe checks here — the code often tracks refrigerator control code before any parts talk.
Reviewed for clarity on KitchenAid appliances; always match the code to your specific model.
1C4C · KitchenAid refrigerator · Refrigerator control code (model-dependent).
Model compatibility: KitchenAid reuses codes across series and model years, so 1C4C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
When a KitchenAid fridge shows 1C4C, techs treat it as a control/sensor path issue around refrigerator control code — not an automatic sealed-system failure. Photograph the display and model tag before resetting. Two KitchenAid units can share a display string yet mean different subsystems; verify the definition for your serial family.
Symptoms you may notice
- The refrigerator shows 1C4C and cooling seems off
- Temperatures drift while 1C4C is displayed
- 1C4C appears alongside unusual cooling behavior
Possible causes
- A cooling-performance issue (varies by model)
- A sensor or control affecting cooling
- Airflow or door-seal problems reducing performance
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
- Confirm the vents inside are not blocked by items
- Confirm the door seals and closes properly
- Note actual temperatures if you can measure them
- Keep notes on any recent power outages, filter changes, or installs before the visit
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
What not to attempt
- Do not open internal panels or access high-voltage components
- Do not bypass door locks, safety switches or interlocks
When to call a technician
Call Artisan Repair if 1C4C comes back, the appliance will not run safely, or you smell burning / see standing water near electrics.
