How to Fix / Troubleshooting
Safety first: Disconnect power before opening the charger. Frequent resets can interrupt charging and stress components.
- 1. Check supply stability:
- Have an electrician verify that the supply voltage is stable and within spec.
- 2. Inspect internal power supply:
- Open the housing and check the power supply module for bulging capacitors or discoloration.
- Reseat connectors to the main control board.
- 3. Improve cooling:
- Ensure vents are clear and the charger is not in a confined, hot space.
If resets continue, replacing the internal power supply module or main control board is recommended.
