6. Troubleshooting
If you encounter issues with your desk frame, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |

| Desk does not move / No power | Power cable disconnected; Outlet issue; Control box malfunction. | Check if the power cable is securely plugged into the wall outlet and the control box. Test the outlet with another device. Ensure all motor and control panel cables are firmly connected to the control box. |
| Desk moves unevenly or stops | Overload; Obstruction; Loose connections. | Reduce the weight on the desk (ensure it's within 275 lbs capacity). Check for any obstructions under or around the desk. Verify all cable connections are secure. Perform a reset (see below). |
