Why is my outdoor outlet not working?

The most common cause is a tripped GFCI, often not at the outdoor outlet itself.

Outdoor outlets are normally protected by a GFCI somewhere on the same circuit. The confusing part is that the reset button may not be outside. It may be in a garage, basement, laundry room, powder room, utility room, or at another exterior receptacle around the house.

Start with the simple checks before removing covers or touching wiring:

• Unplug everything from the outdoor outlet.
• Look for a GFCI receptacle with RESET and TEST buttons nearby or upstream.
• Press RESET firmly until it clicks.
• Check the breaker panel for a breaker that is fully tripped or sitting halfway between ON and OFF.
• Turn a tripped breaker fully OFF, then back ON once.

If the outdoor outlet works after resetting an indoor GFCI, the receptacle outside may not be broken at all. It may be downstream on the GFCI’s protected load side.

This is common in older layouts where one GFCI protects several locations. A single device in the garage might feed the front porch, back deck, and side-yard receptacle. When holiday lights, a pressure washer, a pond pump, or rainwater trips it, all of those outlets can appear dead.

If the GFCI immediately trips again with nothing plugged in, stop resetting it. That usually means moisture, a ground fault, a damaged cable, or a failed GFCI device. Repeated resetting is not troubleshooting; it can mask a real fault. For a broader indoor/outdoor diagnostic path, see why outlets stop working when the breaker is not obviously tripped.

If it stopped after rain, assume water got into the outlet, cover, cord, or connected load.

Rain-related failures usually come from water reaching a live part that should have stayed dry. A GFCI is designed to react quickly to leakage current, so it may trip even when the outlet looks normal from the outside.

The weak points are usually very specific:

Outdoor receptacles should be weather-resistant and protected by a proper cover for the location. Where plugs remain connected outside, such as for patio lighting, pumps, seasonal decorations, or security equipment, the cover needs to protect the outlet while the cord is plugged in. That is the job of an in-use cover, often called a bubble cover.

A wet extension cord is not a safe workaround. Do not keep using a cord that has been lying in snow, puddles, wet grass, or a planter bed. Water inside the cord end can trip the GFCI, shock someone handling it, or corrode the plug blades. Unplug it from the source first, keep it away from people and pets, and let an electrician inspect the outlet if it will not reset after everything is disconnected and dry.

Also check what is plugged in. Outdoor lights, inflatable decorations, garden tools, and low-voltage transformers can all introduce faults. If the outlet resets when everything is unplugged but trips when one item is connected, that item may be the fault, not the receptacle. For landscape systems specifically, the fault may be at the transformer, buried low-voltage cable, photocell, or fixture, which is covered separately in why landscape lights are not working.

If it failed after yard work, look for physical damage before blaming the outlet.

Yard work often damages the wiring path, not just the receptacle. A mower, string trimmer, shovel, aerator, hedge trimmer, or fence repair can nick a cord, crack conduit, loosen a box, or pull a cable connection apart.

Common clues include:

• The outlet worked before mowing, trimming, digging, or deck work.
• The cover is loose, crooked, cracked, or hanging from the box.
• The receptacle moves when a plug is inserted.
• A plug feels loose or falls out.
• The breaker trips only when a specific outdoor tool is used.
• There are burn marks, buzzing, heat, or a smell at the outlet.

Do not open an outdoor electrical box after a fault, especially if it is wet. Outdoor boxes can hold water even when the wall looks dry. A tester may show no power at the face while energized conductors are still present inside the box or upstream.

If the outlet is physically damaged, replacement is not just cosmetic. The repair should address the whole assembly: box, cable connector, grounding path, receptacle rating, gasket, cover, and GFCI protection. A new device in a cracked or leaking box will often fail again.

This is also where extension cords create problems. Outdoor cords are meant to be temporary and appropriately rated for outdoor use. They should not be buried, stapled to a fence, run under doors, pinched in windows, or left permanently across wet ground. If you need regular power for a patio, shed area, camera, fountain, or lighting transformer, a permanent outdoor receptacle or circuit is the safer route. See outdoor outlet installation cost if you are comparing repair versus adding a properly located outlet.

The right repair depends on whether the fault is the device, the protection, the box, or the circuit.

A working repair starts by finding where power stops and why. Replacing the visible receptacle without checking upstream protection, grounding, water entry, and the load side can leave the real fault in place.

For an outdoor outlet service call, we normally work through these checks:

• Verify the breaker position and whether the circuit shares other exterior or garage outlets.
• Test upstream GFCI devices, including line and load connections.
• Confirm voltage, polarity, and grounding at the outdoor receptacle.
• Inspect the box for water, corrosion, loose terminals, damaged insulation, and failed gaskets.
• Check whether the receptacle is weather-resistant and suitable for outdoor use.
• Check whether the cover protects the outlet when a cord is plugged in.
• Isolate connected loads such as lights, pumps, timers, transformers, or decorations.

A failed GFCI receptacle is a common repair. Each GFCI outlet installed typically costs $120–$180 including parts, depending on the device and site conditions. If the box, cover, damaged cable, or circuit run also needs work, the repair is quoted in writing after a site visit. Standard outlet or switch replacement is generally $80–$120 each, but outdoor work often needs weatherproofing parts and testing that indoor replacements do not.

If a new outdoor circuit is required, the cost depends on distance from the panel, finished walls, and the route to the exterior. A typical 20A dedicated circuit from the panel is usually $250–$500 where access is straightforward, while heavier outdoor loads cost more. Any ESA notification required for the work should be included in the written scope, not treated as an afterthought.

For outdoor lighting, patio power, soffit outlets, transformers, or controlled exterior receptacles, the outlet may be part of a larger exterior electrical plan. That is when it makes sense to look at outdoor lighting and exterior electrical service, not just a single receptacle swap.

Call an electrician if the outlet will not reset, gets wet repeatedly, or shows damage.

You can safely try resetting a GFCI once, unplugging connected loads, and checking the breaker. After that, repeated resets or temporary cord fixes are not the answer.

Call for service if any of these are true:

• The GFCI trips immediately with nothing plugged in.
• The breaker trips when the outdoor outlet is used.
• The cover, box, or receptacle is cracked or loose.
• You see water inside the cover or staining around the box.
• The outlet worked before digging, deck work, fencing, trimming, or landscaping.
• Plugs feel loose, hot, scorched, or unstable.
• You need power outdoors often enough that extension cords have become permanent.

An outdoor outlet lives in a harsher environment than an indoor receptacle: rain, snow, UV exposure, freeze-thaw movement, insects, corrosion, and mechanical hits from tools and furniture. A proper repair has to survive that environment.
