The Five Causes
- A tripped GFCI upstream — check every GFCI in the house, especially bathrooms, garage, and outside
- A tripped breaker — one may be halfway between on and off; flip fully off, then back on
- A loose back-stab connection — cheap outlets have push-in wire connections that loosen over time
- A failed outlet — the internal contacts wear out, usually after 20–30 years
- A break in the wire — rare, but rodents, remodel damage, or old cloth-insulated wire can fail mid-run
Safe DIY Steps
1. Check breakers and GFCIs. 2. Test the outlet with a plug-in tester ($10 at any hardware store). 3. If the outlet is dead but others on the circuit work, the outlet itself is likely at fault.

When to Call
If multiple outlets are dead and no breaker is tripped, or you see scorching, or you're not comfortable replacing an outlet, call a licensed electrician. Loose connections cause fires, and there's no way to know how many exist in the wall without opening boxes.
Frequently Asked Questions
Can I replace an outlet myself?+
In California, minor outlet replacement is generally allowed for homeowners on their primary residence. Turn off the breaker, verify with a tester, note the wire positions, and match them. If you see aluminum wire, back-stab connections, or anything unfamiliar, stop and call.
