What TC Means
TC reports the freezer compartment running warmer than its set point for longer than the unit's allowed threshold.
Common Causes of TC
- Door not sealing fully
- Compartment overloaded, blocking internal air circulation
- Sealed system or evaporator fan problem reducing cooling capacity
🔧 One Safe Check You Can Try
Confirm the freezer door is sealing fully and that the compartment isn't overloaded to the point of blocking internal airflow.
⚠ Why You Shouldn't Go Further Than That
- Once door seal and airflow are ruled out, the remaining causes are sealed-system or fan problems needing technician diagnosis.
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.
