Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow cooker does not turn on. | Not plugged in; power outlet not functioning; unit malfunction. | Ensure unit is securely plugged into a working outlet. Check household circuit breaker. If problem persists, contact customer support. |
