Troubleshooting
If you encounter issues with your ModernMate standing desk, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Desk does not move or respond to controls. | Power cable disconnected, power outage, control unit malfunction. | Check if the power adapter is securely plugged into both the wall outlet and the desk. Verify the wall outlet has power. If the issue persists, contact customer support. |
| Desk stops mid-raise/lower. | Temporary obstruction, motor safety feature engaged. | Remove any obstructions. Press the adjustment button again to resume movement. If it repeatedly stops, check for excessive weight or damage. |
