Possible Causes

Marginal sealing at cable gland or enclosure, Micro-cracks in connector allowing moisture in, Contaminated GFCI sensor, Condensation on internal boards

How to Fix / Troubleshooting

Safety first: Treat weather-related trips as potential ground faults. Turn off power before opening the unit.

Steps to troubleshoot:

  • Inspect seals and glands: Check the cable entry and enclosure seams for gaps or deteriorated gaskets. Replace or reseal as needed.
  • Connector condition: Look for hairline cracks or gaps in the J1772 handle body. Replace if compromised.
  • Clean internal components: Dry and clean the GFCI sensor and nearby wiring with isopropyl alcohol if contamination is visible.

If weather continues to affect operation after sealing and cleaning, the GFCI sensor or main control board may need replacement.
