7. Troubleshooting
If you encounter issues with your compressor, try these common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | No power from 12V socket; Vehicle's fuse blown; Overload protection tripped. | Ensure 12V plug is fully inserted and vehicle engine is running. Check vehicle's fuse box for a blown fuse and replace if necessary. Allow compressor to cool down and check/reset overload protection. |
| Slow inflation or no air output. | Loose connection; Air hose leak; Incorrect adapter; Item valve blockage. | Ensure all connections (power, hose to valve) are secure. Check air hose for visible damage. Verify the correct adapter is used and properly attached. Check the item's valve for obstructions. |
| Compressor overheats and shuts off. | Continuous operation for too long; Blocked ventilation. | Turn off the compressor and allow it to cool down for at least 15-20 minutes before resuming use. Ensure ventilation openings are not blocked. |
