Charger randomly resets or reboots during charging without any error code.

Safety first: Frequent resets can interrupt charging but usually do not expose live parts; still follow normal precautions.

• 1. Check supply stability: Have an electrician verify that the supply voltage does not sag excessively when the charger and other loads operate.
• 2. Improve cooling: Ensure vents are clear and the charger is not exposed to direct sunlight or other heat sources.
• 3. Reseat internal connectors: With power off, open the housing and reseat all low-voltage connectors between the power supply, control board, and display.
• 4. Inspect for dust and corrosion: Clean any buildup that might cause tracking or intermittent shorts.
• 5. Replace control board: If resets continue despite stable power and good connections, the internal power supply or microcontroller on the main board is likely failing and should be replaced.
