One outlet is dead. You check the breaker panel — everything looks ON. No tripped breaker. This is one of the most common mysteries homeowners call us about, and the answer is almost always one of three things: a tripped GFCI you have not found yet, a loose wire at the outlet or upstream connection, or a failed outlet.
Most Common Causes
- Upstream GFCI tripped. One GFCI in a bathroom, garage, or exterior wall can protect multiple standard outlets downstream — including in other rooms. The dead outlet may not be a GFCI at all.
- Tripped AFCI or GFCI breaker in panel. Some circuits use breaker-type protection instead of outlet GFCIs. The breaker may be tripped even if it does not look obviously off.
- Loose stab-in connection. Outlets pushed into the back of the device (“back-stab”) loosen over time — especially with Florida humidity cycles.
- Broken neutral. A loose neutral can kill multiple outlets on a circuit while the breaker stays on — this is a fire hazard.
Safe DIY Troubleshooting
- Search for ALL GFCIs. Check bathrooms, kitchen, garage, laundry, exterior, and pool area. Press RESET on each.
- Firmly cycle the breaker. OFF, wait 5 seconds, ON — even if it looks fine.
- Test with a lamp. Plug a known-good lamp into the dead outlet after resets.
- Check half-hot switched outlets. A wall switch may control one half of a duplex outlet — switch ON.
- Stop if multiple rooms lose power. Call an electrician — possible neutral or multi-wire branch circuit issue.
