An outdoor or garage Ground Fault Circuit Interrupter (GFCI) outlet frequently refuses to reset after heavy rainfall because moisture ingress has created an electrical bridge or ground fault inside the receptacle housing or exterior weatherproof box. Water is conductive and triggers the GFCI safety mechanism to trip continuously, preventing power delivery to avoid shock hazards. Until the moisture evaporates completely or is dried out, the internal latching solenoid will not hold. You can troubleshoot weather-related faults safely by isolating power first. You can verify that your corrective action is successful when shutting off the breaker, drying out the junction box thoroughly with a hairdryer, and ensuring a tight weatherproof cover is installed allows the reset button to click and hold power securely.
