| Controller does not power on. | No power from USB source, faulty USB cable, or faulty controller. | Ensure USB power source is active. Try a different USB port or power bank. Check the cable for visible damage. |
| Heating element does not heat up. | Heating element not properly connected, faulty heating element, or controller not set to a heat level. | Verify the heating element is securely plugged into the controller. Ensure the controller is powered on and set to High, Middle, or Low. Test the heating element with a different power source if possible. |
| Heat level does not change. | Button malfunction or internal issue. | Press the button firmly. If the issue persists, the controller may be faulty. |
