What does Fault 41 mean on my Powerbank UPS?
- EElizabeth GallagherAug 26, 2025
Fault 41 on your Powerbank UPS means the internal temperature is too high, causing it to shut down. This can happen if: 1. The environment is too hot. 2. The fan is blocked or has failed. 3. The ventilation is blocked. 4. The UPS is overloaded. Make sure the ambient temperature is not over 40ºC, ensure the fan is working, provide adequate ventilation, and reduce the load if possible.
