How to Fix / Troubleshooting
Safety first: Frequent resets can eventually damage contactors and relays. Avoid heavy use until resolved.
- Check mains stability: Have an electrician verify that the mains supply is stable and within tolerance.
- Inspect PCB (power off): Look for bulging capacitors, burn marks, or loose connectors on the control PCB, especially around the power supply section.
- Improve cooling: Ensure adequate ventilation around the charger and that any internal fan is working.
- Firmware update: Install the latest firmware to address potential software bugs causing resets.
- Replace control PCB: If resets continue despite stable supply and updated firmware, the PCB’s power supply or processor may be failing and should be replaced.
