Charger gets very hot to the touch during normal charging, though it continues to operate.

Safety first: If the housing is too hot to touch comfortably, stop charging and allow it to cool. Overheating can lead to failure or fire.

• 1. Improve airflow:
  • Ensure the charger is mounted with adequate clearance on all sides.
  • Remove any objects leaning against or covering the unit.
• 2. Check internal fan:
  • With power off, open the housing and inspect the fan (if present).
  • Clean dust and verify the fan spins freely; replace if not running when the charger is active.
• 3. Verify wiring size:
  • Have an electrician confirm that the circuit wiring and breaker are correctly sized for the charger’s current rating.
• 4. Reduce duty cycle:
  • If possible, lower the charging current setting on the vehicle or charger (for adjustable Megear models).
  • Avoid charging continuously at maximum current in very hot conditions.

Persistent excessive heating indicates a need for professional evaluation of the charger and supply wiring.
