Safety: Overheating can lead to fire. Do not cover the charger or operate it above rated current.

Check current setting: In the go-e app or via DIP switches (depending on model), verify that the maximum charging current does not exceed the cable size and breaker rating. Reduce the current and test again.
Improve ventilation: Ensure the charger is not installed in a sealed box or covered by objects. Maintain the clearance recommended in the manual and avoid direct sunlight if possible.
Inspect for heat damage: With power OFF, open the housing and look for browned plastic, melted insulation, or a burnt smell around the terminal block and power board. Tighten all high-current connections.
Monitor temperature: Use the app (if supported) to monitor internal temperature during a test charge. If temperature rises rapidly even at low current, the internal power board or temperature sensor may be defective and should be replaced.
Do not bypass protection: Never attempt to bypass thermal sensors or fuses. Replace faulty components with original go-e parts.

Charging stops and E04 is displayed; often associated with overcurrent or internal overtemperature protection.
