Direct Answer
If your outdoor outlets stop working after rain, the most likely cause is a tripped GFCI outlet that needs to be reset, or a GFCI that has failed and needs replacing. Outdoor outlets are required by code to be GFCI-protected because moisture and electricity are a dangerous combination, and that protection trips fast when water gets involved. In some cases, water has actually entered the outlet box itself, which means the fix goes beyond a simple reset.
Why Rain Triggers a GFCI Trip
A ground fault circuit interrupter works by constantly comparing the current flowing out of the hot wire to the current returning through the neutral. The moment those numbers differ by as little as 5 milliamps, it cuts power in a fraction of a second. Rain creates exactly the kind of leakage path that triggers this response.
Common Ways Moisture Gets In
Even a small gap matters. Cracked or missing weatherproof covers let rain splash directly onto the receptacle face. Old outlet gaskets dry out and shrink over time, leaving space around the edges. Conduit fittings that weren’t sealed properly act as a funnel, directing water straight to the wiring. Any of these paths can cause a nuisance trip or, worse, a ground fault that keeps tripping every time power is restored.
It’s also worth checking whether the outlet box has a “while-in-use” cover. Standard flip covers are only rated for protection when nothing is plugged in. If you’re running a power tool or holiday lights outdoors, you need a bubble-style cover that stays closed around the cord. Many older homes in the area were built before this became standard practice.
When the GFCI Has Actually Failed
A GFCI outlet has a lifespan. Most manufacturers rate them for around 10 to 15 years, and exposure to heat, cold, and moisture shortens that. If you press the reset button and it won’t click, or it trips again within seconds, the device itself may have worn out. A failed GFCI that won’t hold a reset is not something to work around with an extension cord from inside. That’s a replacement job. Switch and outlet installation in Palos Hills covers exactly this kind of repair when a receptacle has reached the end of its service life.
What to Check Before Calling an Electrician
You can safely do a few things yourself before picking up the phone.
Locate the Controlling GFCI
Outdoor outlets are often protected by a GFCI that’s actually located indoors. Garages, bathrooms, and utility rooms are common spots. One GFCI can protect multiple downstream outlets on the same circuit, so the dead outdoor receptacle may be controlled by a GFCI you’ve never touched. Walk through those rooms and look for a black “TEST” button and red “RESET” button on any outlet. Press the reset firmly until you hear a click, then check your outdoor outlet again.
If none of the indoor GFCIs seem connected to the outdoor outlet, check your electrical panel for a tripped breaker. A breaker that has moved to the middle position needs to be pushed fully off before it can be reset to on.
Signs You Need a Pro
Call a licensed electrician when the reset doesn’t hold, when you see burn marks or discoloration around the outlet face, when you smell something burning near the box, or when the outlet is completely dead and no GFCI or breaker appears to be tripped. Water intrusion that reaches the wiring behind the box can damage insulation and create a shock risk that isn’t visible from the outside. A proper electrical inspection in Palos Hills can identify hidden water damage before it becomes a bigger problem.
Homes near the city of Palos Hills that were built in the 1970s and 1980s often have older wiring that wasn’t designed with today’s outdoor power demands in mind. Adding a proper weatherproof outlet with updated GFCI protection is a relatively quick job for a licensed electrician. The OSHA guidance on ground fault hazards makes clear why skipping this repair is not a safe option.

Can I replace an outdoor GFCI outlet myself?
Swapping a GFCI receptacle is within the skill range of a careful DIYer who knows how to turn off the breaker and confirm power is off with a voltage tester. That said, if the wiring inside the box looks corroded, melted, or the box itself has standing water damage, stop and call a licensed electrician. Moisture-compromised wiring needs more than a new outlet.
How many outdoor outlets should a house have on one GFCI circuit?
There’s no strict code limit on how many outlets one GFCI can protect downstream, but practical wiring usually puts two to four outdoor outlets on a single 20-amp circuit. The problem comes when high-draw tools trip the GFCI from overload rather than a ground fault. If your outdoor circuit trips frequently under load, a dedicated outdoor circuit is often the right fix rather than simply resetting the same GFCI over and over.
