The patio outlet works all summer. Then the rain starts and it won't stay on.
That's the GFCI doing its job. A GFCI doesn't watch for too much power — that's the breaker's job. It watches for current leaking where it shouldn't go, like through water or a damaged cord, and shuts the outlet off in a fraction of a second. When it trips every time it rains, something is giving current a path it shouldn't have.
Rain doesn't create the problem. It finds it. The usual suspects:
- Water getting into an outdoor outlet box or cord connection. The cover might look fine from the driveway and still let water in around the edges.
- A cracked or UV-damaged fixture or cord that's been sitting in the weather for years.
- Yard equipment or lights plugged in with indoor-rated cords.
- An outlet or cover that was never rated for wet locations to begin with.
Here's what helps us find it: where the outlet is, what's plugged into it, and when it trips. "Trips ten minutes into every rainstorm, nothing plugged in" tells a different story than "trips when the string lights are on." Note it from inside the house. Don't open the box, don't touch wet equipment, and don't stand in a puddle messing with an outlet.
What not to do: don't replace the GFCI with a regular outlet to "fix" it. Don't hold the reset button down or reset it over and over hoping it sticks. The tripping is the protection working. Bypassing it is how people get hurt.
What we'll check: the outlet itself, the connections inside the box, the cover, and the circuit it's on. Sometimes the device has failed — GFCIs wear out, especially outdoors. Sometimes the cover needs replacing with a proper in-use weatherproof cover. Sometimes the wiring needs attention. The fix follows what we find.
Does a tripping GFCI mean it's bad? Not necessarily. It usually means it's doing exactly what it was installed to do. And a cover on the outlet doesn't prove anything — a cheap or broken cover is often part of the problem, not the solution.
