Charger displays E05 and stops charging; may occur during hot weather or long high-current sessions.

Safety: Overheating can lead to fire. Turn OFF the breaker and allow the unit to cool before touching it.

• 1. Check installation clearance:
  • Ensure at least the manufacturer-recommended clearance around the AMPROAD charger (typically several inches on all sides).
  • Remove any objects blocking airflow or covering vents.
• 2. Inspect for dust and debris:
  • With power OFF, open the enclosure and gently blow out dust from heat sinks, vents, and the internal fan using dry compressed air.
• 3. Verify fan operation:
  • Restore power and start a charge session while observing the internal cooling fan (if visible through vents).
  • If the fan does not spin when the unit is under load, the fan or its driver circuit may be faulty and should be replaced.
• 4. Check terminal tightness:
  • Turn power OFF again and inspect the main power terminals for discoloration or melted insulation.
  • Tighten loose terminals and replace any heat-damaged wiring.
• 5. Temperature sensor check:
  • If the unit reports E05 even when cold, the temperature sensor on the power board may be defective.
  • Replace the power board or sensor assembly per AMPROAD service documentation.
• 6. Retest: After corrections, power-cycle the unit and run a monitored charge session to confirm normal operation without E05.
