Outlet Has No Power
A dead outlet is almost never a complicated electrical problem — the fix is usually a tripped GFCI outlet somewhere else in the home or a tripped circuit breaker. GFCI outlets can protect multiple downstream outlets in other rooms, and many homeowners never learn which outlets are connected. Before any wiring work, spend two minutes resetting every GFCI outlet in every bathroom, the kitchen, the garage, and any outdoor outlets. This resolves about 80% of dead outlet calls.

Common Symptoms
- Outlet has no power — lamp or device doesn't work
- Only some outlets in a room are dead
- Outlet worked yesterday and now is completely dead
- Multiple outlets in different rooms suddenly dead at once
- Outlet tester shows 'open hot' or 'open neutral' condition
Most Likely Causes
- 1
Tripped GFCI Outlet Upstream (Most Common)
A single GFCI outlet can protect many downstream outlets wired through its LOAD terminals — outlets that may be in completely different rooms or areas of the home. When the GFCI trips (from a ground fault, moisture, or a faulty appliance), all protected downstream outlets lose power simultaneously. These dead outlets give no indication that they're GFCI-protected — they look like ordinary outlets. Reset every GFCI in the home before investigating further.
- 2
Tripped Circuit Breaker
The circuit breaker for the dead outlet has tripped, cutting power to the entire circuit. Single-pole 120V breakers trip to the OFF or middle position — look for any breaker that appears slightly different from the others. Reset by pushing fully to OFF then back to ON. Breakers can trip from overloaded circuits (too many high-draw devices on one circuit) or from ground faults.
- 3
Open Neutral or Hot Wire Connection
A wire connection has come loose at the dead outlet or at a device earlier in the circuit. Outlets are commonly wired in series (daisy-chained) — a loose connection at one outlet breaks power to all outlets connected after it on the same circuit. The break can be at the outlet's screw terminal or, less commonly, a wire nut connection in a junction box has failed.
- 4
Wiring Fault — Open or Damaged Wire
Less common than the above causes, but a physically damaged wire (from a nail puncture, rodent damage, or failed splice) can cause permanent open circuit. A wire punctured by a drywall screw or nail is a particularly common cause of newly-dead outlets after renovation work in adjacent walls or ceilings.

Quick DIY Checks
Turn off the circuit breaker before removing an outlet from its box or touching any outlet wiring. Verify the circuit is off with a non-contact voltage tester before proceeding — circuits can be wired in unexpected ways, and the breaker you think controls the outlet may not be correct.
- 1Before touching any wiring, locate and reset EVERY GFCI outlet in the home — bathrooms (all of them), kitchen countertop areas, garage, laundry room, basement, and any outdoor outlets. Press the RESET button firmly until it clicks on each one. Then retest the dead outlet.
- 2Check the circuit breaker panel for any breaker that looks different from the others — in the middle (tripped) position, or slightly offset. On older Federal Pacific or Zinsco panels, breakers may not visually indicate a trip. Reset suspect breakers by pushing fully OFF then back to ON.
- 3Use an outlet tester (a plug-in device with indicator lights, available at any hardware store for $10–$15) to check the dead outlet. The indicator lights show: correct wiring, open hot, open neutral, open ground, hot/neutral reversed, or hot/ground reversed. This tells you exactly what type of fault is present.

Check the screw terminal connections on the back of the outlet — wires should be firmly attached. Also check the outlet directly before this one on the circuit (if identifiable) for loose connections.
- 5Test voltage at the outlet terminals directly with a voltmeter (with breaker on): L1 to ground should read 120V. If you read 0V, the hot wire is open; if you read 120V but the outlet tester showed open neutral, the neutral wire connection is broken. These readings guide whether the problem is at this outlet or upstream in the circuit.

Repair vs Replace
Dead outlets are almost always resolved by resetting a GFCI, resetting a breaker, or replacing a $3–$8 outlet. The diagnostic process takes longer than the actual repair. Only escalate to significant cost if the wiring itself is damaged — from a nail, rodent, or failed splice — which requires opening the wall or accessing junction boxes.
Est. Repair Cost
$0 (GFCI reset) to $30 (outlet replacement)
Est. Replacement Cost
N/A — outlet replacement is the standard repair; wire repair or rewiring costs $200–$600 if wiring is damaged

Frequently Asked Questions
- Why would resetting a GFCI in the bathroom fix an outlet in a completely different room?
- GFCI outlets protect downstream outlets wired through their LOAD terminals — outlets that can be anywhere in the home, not just in the same room. Code requires GFCI protection in wet locations (bathrooms, kitchens, garages, outdoors), and electricians often wire multiple downstream outlets through a single GFCI to minimize cost. The result is that a bathroom GFCI can protect a hallway outlet, a garage GFCI can protect outdoor outlets, and so on. It's intentional, but confusing when you don't know the wiring map.
- I reset every GFCI and all the breakers and the outlet is still dead — what's left?
- At this point the fault is in the outlet itself or the wiring to it. Use an outlet tester to check the outlet's wiring condition, then turn off the breaker, remove the outlet, and check all terminal connections for loose wires. If connections are tight and the outlet tests as wired correctly but has no power, the fault is upstream in the circuit — a loose wire nut in a junction box or a failed connection at an outlet earlier on the circuit. Tracing the circuit requires an electrician or a circuit tracer tool.
- My outlet tester shows 'open ground' — is that why there's no power?
- No — an open ground means the outlet has no functional ground wire, but the outlet still has power (hot and neutral are connected). An outlet tester that shows 'open ground' indicates a wiring deficiency (missing or disconnected ground conductor) but does not cause loss of power. If the outlet has 'open ground' and also no power, there are two separate issues. Fix the power problem first (tripped GFCI or breaker, loose connection), then address the open ground separately.
