Check the GFCI Reset Button First
Outdoor outlet troubleshooting has gotten complicated with all the conflicting advice flying around. As someone who has chased down dead outdoor outlets through three different houses, I learned everything there is to know about this particular headache. Today, I will share it all with you.
But what is GFCI protection? In essence, it’s a safety system that cuts power the instant it detects current leaking somewhere it shouldn’t. But it’s much more than that — it’s also the reason your outlet is dead right now and you have no idea why.
Here’s the thing most people miss: outdoor outlets are either GFCI outlets themselves (the ones with “TEST” and “RESET” buttons right on the face) or they’re wired downstream from a GFCI breaker or outlet sitting somewhere inside your home. That upstream protector is usually in the garage, a bathroom, the laundry room — or on another outdoor outlet you completely forgot existed.
I spent twenty minutes crouched behind my barbecue inspecting an outlet on the back of my house. Checked the wiring twice. The real problem was a GFCI outlet I’d installed in the garage back in 2019 and never looked at again. One reset button. Everything worked. Don’t make my mistake.
So, without further ado, let’s dive in. Here’s how to find your GFCI:
- Look at the dead outlet first. Two buttons on the face means it’s a GFCI outlet itself — press the RESET button, usually red or black.
- Standard outlet face with no buttons? Trace the circuit backward. Check the garage, every bathroom, and any other outdoor outlet on the same wall or circuit.
- No outlet GFCI found anywhere? Head to your main electrical panel and look for a breaker with a small RESET button built into it. That’s a GFCI breaker.
- Press the RESET button firmly. Hold it a full second. After a wet trip, the button sometimes doesn’t pop out visibly even though the outlet is completely dead. Press it anyway.
This single step resolves most cases. Probably 60% of outdoor outlet failures after rain come down to a tripped GFCI waiting for someone to push a button.
Why Rain Causes Outdoor Outlets to Trip
GFCI devices measure the difference between current flowing out and current returning. Water bridging that gap looks like current leaking to ground — and the device shuts down immediately. That’s not a malfunction. The technology is working exactly as designed. That’s what makes GFCI protection endearing to us homeowners who’d rather not get electrocuted.
The actual problem is almost always the weatherproof cover. A cracked gasket, a missing cover, a box sitting even slightly proud of the wall — any of those creates a gap. Rain finds gaps. Even an opening the width of a dime lets enough moisture inside the electrical box to trigger a fault.
Inspect the Weatherproof Cover and Box for Damage
Probably should have opened with this section, honestly. Once you’ve reset the GFCI and power is restored, look at what’s actually protecting the outlet from weather.
Standard flip covers — the basic $5 plastic ones on most installations — fail regularly in sustained rain. The gasket dries out around year three or four. The plastic warps. Water pools on top and works its way around the edges. I’m apparently a chronic under-buyer of weatherproof hardware, and a $6 Home Depot cover works for me until it doesn’t, while a properly rated in-use cover never lets water in at all.
Walk outside and check these specific points:
- Is the weatherproof cover actually there? Sounds obvious. Covers get broken, removed during a project, and never reinstalled.
- Is the gasket cracked or compressed? The rubber seal inside the cover should feel pliable. Hard, brittle, or split means it’s not sealing anything.
- Does the outlet box sit flush against the wall? A visible gap — especially common when siding gets added after the original installation — lets water run directly behind the cover and into the box.
- Is there water or mineral residue inside the box? Open the cover and look. White crusty deposits mean moisture has been getting in for a while.
I’ve watched people replace entire outlets when the fix was a $15 weatherproof cover. The outlet was fine. The cover was a disaster.
When to Reset the Breaker vs Call an Electrician
If the GFCI reset worked and the outlet has power again, you’re not finished. Test it.
Plug in something small — a radio, a lamp, a phone charger. Low-power, nothing demanding. If the outlet holds and stays on, you probably caught it early. Moisture dried out, the GFCI did its job, done. If it trips again within seconds or minutes, stop using it.
Call a licensed electrician if any of these apply:
- The outlet trips immediately on use, even with a low-draw device plugged in.
- There’s a smell of burning plastic or visible scorch marks around the outlet or cover.
- You can see water inside the electrical box itself or on the wiring.
- The outlet has tripped more than twice in the past week despite your efforts to dry it out.
Water inside a live electrical box is a fire hazard. Full stop. Repeated faults mean either the box is compromised or something in the circuit is damaged — neither of those is a DIY fix. A typical electrician diagnosis visit runs $150 to $250, parts included for a simple repair. That’s cheaper than a house fire. It won’t fix itself. It won’t.
Preventing the Problem After the Fix
Once the outlet is working again, upgrade what’s protecting it.
While you won’t need a full electrical renovation, you will need a handful of inexpensive materials. Standard flip covers run $5 to $10 and fail on a schedule. In-use weatherproof covers — sometimes labeled “while-in-use” covers — run $20 to $40 and stay sealed even with a cord plugged through them. Hubbell and Leviton both make solid versions. They’re deeper, better-gasketed, and built for exactly this scenario.
Hubbell’s WP26 might be the best option, as outdoor protection requires a genuine seal under load. That is because standard covers were never designed to stay weathertight with a cord running through the hinge gap — in-use covers solve that by design.
Beyond the cover, check the caulking where the outlet box meets your siding or sheathing. Cracked or missing caulk means water runs behind the box entirely — no cover fixes that. Seal it with exterior-grade silicone, something like GE Silicone II in clear. A $6 tube.
Two or three steps and you’ve actually solved it:
- Install an in-use weatherproof cover rated for your climate and usage.
- Seal the box perimeter with exterior silicone caulk.
- Check the cover and gasket once a season — before heavy rain arrives, not after.
First, you should have a licensed electrician inspect the box and wiring before you button everything back up — at least if the outlet has tripped more than twice in the last month. The inspection costs less than the repair if you catch something early. Peace of mind is worth the call.
