What C1 (111-prefix) Means
C1 on a 111-prefix Kenmore bottom-freezer refrigerator is the one code on this platform that names the sealed refrigeration system: the control has detected either a low refrigerant charge or a failed compressor.
Common Causes of C1 (111-prefix)
- A refrigerant leak somewhere in the sealed circuit
- A failed or failing compressor
- A restriction in the capillary or drier limiting refrigerant flow
🔧 One Safe Check You Can Try
Move anything genuinely perishable to another appliance or a cooler now rather than waiting to see whether the temperature recovers; the sealed system is not a wait-and-see fault.
⚠ Why You Shouldn't Go Further Than That
- Refrigerant recovery and recharge is regulated work requiring certification and equipment, not a job with any DIY path at all.
- Refrigerant released into a kitchen displaces air and can be harmful, which is why the recovery step exists.
- Opening a sealed system without the right equipment lets moisture in, which destroys the circuit even if the leak is found.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
