Outdoor Outlet
Not Working?
Outdoor outlet calls spike every spring after the first rain and again in November when holiday lights go up. Here are the 5 real reasons outdoor outlets fail, in order, with the fix for each.
If your outdoor outlet stopped working, the cause is almost always a tripped GFCI: either at the outlet itself, or at an indoor outlet (often in the bathroom or garage) that protects it. Reset every GFCI in the house first. If that doesn't fix it, the next four causes (in order) are moisture inside the outlet, a failed in-use cover letting water in, a burned-out outlet from sun and temperature exposure, and wire damage from rodents or landscaping.
Outdoor outlet calls hit hardest in two windows. The first is March through May, when the rain returns and a winter's worth of moisture finally pushes a marginal outlet over the edge. The second is November and December, when homeowners plug in holiday lights for the first time in eleven months and discover the outlet has been dead since last spring.
Across Vancouver WA, Camas, Battle Ground, Longview, and the rest of Clark and Cowlitz County, our crew sees the same five causes over and over. Work through them in this order before you call anyone.
1. A tripped GFCI (most likely)
Outdoor outlets are required by code (NEC 210.8) to be GFCI-protected. The GFCI is either built into the outlet itself (the one with test and reset buttons) or it's at an outlet upstream of the outdoor receptacle, often in a bathroom, garage, or laundry room.
Rain is the number one trigger. Even tiny amounts of water inside the outlet box, the cover, or the device plugged in create a path for current to leak to ground. The GFCI senses the leak and trips. The outdoor outlet goes dead. Sometimes this happens hours after the rain stops as water tracks through the box.
The fix:
- Press reset on the outdoor outlet first
- If that doesn't work, reset every GFCI in the kitchen, every bathroom, the garage, and the laundry room
- Unplug whatever was on the outdoor outlet (holiday lights, pump, charger) and try again
- If the GFCI clicks but won't stay reset, see our GFCI won't reset guide
2. Moisture inside the outlet box
Outdoor outlets are sealed with weatherproof gaskets and an in-use cover, but those wear out. Once water gets behind the cover, it pools at the bottom of the box and slowly corrodes the connections. The outlet may work intermittently for weeks before it dies for good.
How to spot it
Pull the cover off and look for any of these:
- ● Green or white corrosion around the screw terminals
- ● Water stains on the box
- ● A musty smell when the cover comes off
- ● Visible standing water at the bottom of the box
If you see any of those, the outlet is done. Don't try to dry it out and reuse it.
The fix:
- Replace the outlet, the box gasket, and the in-use cover together
- Check the wires at the back of the device for corrosion damage
- Replace the box itself if the seal between box and siding has failed
We see this regularly on south- and west-facing walls that take direct rain in PNW storms.
3. The in-use cover failed or is missing
NEC 406.9 requires in-use weatherproof covers on outdoor outlets where anything is plugged in regularly. The deeper bubble-style covers close over a plug while it's still in the receptacle. The flat metal flap covers that were standard on older homes only seal when nothing is plugged in: a holiday-light cord or a pump cord effectively defeats them.
Compliant: in-use cover
Deep bubble cover that seals around a plugged-in cord. Required by NEC 406.9 anywhere something is plugged in regularly.
Old style: flap cover
Flat metal cover that only seals when nothing's plugged in. Common on pre-2008 outdoor outlets. Not compliant for in-use locations.
When an in-use cover breaks (spring fails, plastic cracks, gasket dries out), water gets in and you're back to causes 1 and 2.
The fix: install a proper in-use cover sized for what you're plugging in. Plastic covers from Hubbell, Leviton, or Pass & Seymour run $20 to $40 at the hardware store. Make sure it's rated for the orientation of your outlet (vertical vs horizontal) and that the gasket seats flat against the siding.
"Newman Electric helped me bring my outdoor electrical up to code. They added GFCI protection where it was missing, replaced the broken in-use covers, and ran a new circuit for my landscape lighting. Clean work, fair price, and they handled the permit."

4. The outlet has burned out from sun and temperature exposure
Outdoor outlets live in the worst electrical environment in the house. Direct UV exposure, freeze-thaw cycles every winter, salty marine air on properties closer to the Columbia River, and cumulative moisture all degrade the plastic and the metal contacts inside the device. A residential-grade outlet on a sunny south wall can fail in under ten years.
Signs the outlet itself is shot:
- Yellowed, brittle, or chalky plastic on the face
- A loose feeling when you plug something in
- Visible corrosion or discoloration around the slots
- The outlet works intermittently when you wiggle the plug
- A faint burnt smell, even with nothing plugged in
The fix: replace the outlet with a weather-resistant (WR-rated) GFCI receptacle. Code (NEC 406.9(B)) requires WR-rated devices on all damp and wet locations. Spec-grade or commercial-grade WR outlets last significantly longer than builder-grade residential ones.
5. Wire damage at the box (rodents, landscaping, settling)
Outdoor outlets are usually fed by a wire that runs through a wall or under the eave. Anywhere along that run, the wire can be damaged enough to break the circuit.
Common damage causes
- ● Rodents chewing on Romex insulation in the wall cavity
- ● Landscaping crews driving shovels or edgers into the wall
- ● Settling on older homes pinching the wire where it enters the box
- ● Loose connections at a hidden junction box upstream
How to spot it: the breaker holds (no obvious trip), the GFCI tests fine on the bench, but no power is reaching the outdoor outlet. The break is somewhere in the run between the panel and the receptacle.
The fix: this one needs an electrician with a tone generator and a voltage tester. Tracing a broken conductor inside a wall takes patience. The repair usually involves opening the wall at the break point, splicing fresh wire in a new accessible junction box, and re-pulling the run.
What code requires for outdoor outlets
Under the 2023 NEC (adopted by Washington under WAC 296-46B in April 2024), every outdoor outlet must be:
- GFCI-protected (NEC 210.8(A)(3))
- Weather-resistant (WR) rated device (NEC 406.9(B))
- Fitted with an in-use weatherproof cover where anything is plugged in regularly (NEC 406.9(B))
- Mounted in a weatherproof box with proper gasketing
If your existing outdoor outlet doesn't meet those, the next time an electrician is there is the time to upgrade. It's typically a same-visit fix that takes well under an hour per outlet.
Frequently Asked Questions
Why is my outdoor outlet not working?
Most often a tripped GFCI, either at the outdoor outlet or at an indoor outlet upstream that protects it. Reset every GFCI in the kitchen, bathrooms, garage, and laundry. If that doesn't fix it, suspect moisture inside the outlet, a failed in-use cover, a burned-out outlet, or wire damage somewhere in the run.
Why does my outdoor outlet stop working when it rains?
Rain creates a small current path to ground and the GFCI trips to prevent shock. If your outdoor outlet trips every time it rains, the cover or gasket is letting water in, the outlet has degraded, or whatever is plugged in has compromised insulation. Replace the cover with an in-use bubble cover and check the outlet condition.
Are outdoor outlets supposed to be GFCI?
Yes. NEC 210.8 has required GFCI protection on every outdoor receptacle since 1973. Washington adopted the 2023 NEC under WAC 296-46B effective April 2024. Older homes installed before that requirement may still have non-GFCI outdoor outlets and those should be upgraded as a basic safety improvement.
What is an in-use weatherproof cover?
A deeper outdoor outlet cover (sometimes called a bubble cover) that closes over a plug while it's plugged in, keeping rain off the connection. Code (NEC 406.9) requires in-use covers on all outdoor receptacles where something is plugged in regularly: holiday lights, pumps, yard equipment.
Why does my outdoor Christmas light outlet keep tripping?
Holiday lights are common GFCI trippers. Cracked sockets, loose end caps, and rodent damage to cords all create ground faults. Inspect every strand. Replace any with damaged insulation or cracked sockets. Plug them into a dedicated GFCI outlet rather than chaining strings on a worn extension cord.
How much does it cost to fix or replace an outdoor outlet in Vancouver WA?
Replacing an existing outdoor outlet runs $150 to $300 in Vancouver WA, including a new GFCI receptacle and an in-use cover. Adding a new outdoor outlet from scratch runs $250 to $500 depending on distance from the panel and whether trenching or conduit is needed. Newman Electric provides free on-site estimates.
