Quick answer
If your outlet isn't working but the breaker is fine, first check if other outlets on the same circuit are affected. Turn off the power at the breaker, then test the outlet with a voltage tester. If no power is detected, inspect the outlet for loose wires or internal damage. Replace the outlet if needed.
Confirm the symptom
- Outlet is not providing power
- Circuit breaker is in the 'on' position
- Other outlets on the same circuit may or may not be working
- No tripped GFCI outlets nearby
- No visible damage or burning smell at the outlet
Tools and prep
- Non-contact voltage tester
- Screwdriver set
- Wire stripper
- Multimeter
- Needle-nose pliers
- Electrical tape
- Outlet tester

Prep & safety
- Turn off the power to the outlet at the circuit breaker before starting any work.
- Ensure the outlet is completely powered down using a voltage tester.
- Work in a dry area to prevent electrical hazards.
- Avoid working alone; have someone nearby in case of emergencies.
Step-by-step troubleshooting
- Check for Tripped GFCI OutletsDo: Look for GFCI outlets in the same area (e.g., kitchen, bathroom) and press the 'Reset' button if tripped.Observe: GFCI outlet resets and powers on.Means: The issue was a tripped GFCI outlet.Next: If the outlet works after resetting, no further action is needed.
- Test Other Outlets on the Same CircuitDo: Use a lamp or small appliance to test other outlets on the same circuit.Observe: Other outlets are either working or not working.Means: If other outlets are also out, the issue is likely with the circuit breaker or wiring. If only one outlet is out, it may be the outlet itself.Next: If only one outlet is out, proceed to the next step. If multiple outlets are out, check the circuit breaker.
- Inspect the Outlet for DamageDo: Visually inspect the outlet for signs of damage, burning, or loose wires.Observe: Outlet shows visible damage or loose wires.Means: The outlet may need to be replaced.Next: If damage or loose wires are found, proceed to the next step. If not, continue troubleshooting.
- Test the Outlet with a Voltage TesterDo: Use a non-contact voltage tester to check if power is reaching the outlet.Observe: Voltage tester lights up or beeps, indicating power is present.Means: Power is reaching the outlet, but the outlet may be faulty.Next: If power is present, proceed to the next step. If not, check the circuit breaker again.
- Check the Circuit BreakerDo: Turn off the power to the outlet at the circuit breaker and then turn it back on.Observe: The circuit breaker resets and powers on.Means: The issue may have been a temporary power interruption.Next: If the outlet still doesn't work, proceed to the next step.
- Test the Outlet with a MultimeterDo: Use a multimeter to test the voltage at the outlet's terminals.Observe: The multimeter reads the expected voltage (typically 120V).Means: The outlet is receiving power but may have internal issues.Next: If the multimeter reads correctly, proceed to the next step. If not, check the wiring.
- Inspect and Tighten WiresDo: Carefully remove the outlet cover and inspect the wiring. Tighten any loose wires.Observe: Wires are secure and properly connected.Means: Loose wires may have been causing the issue.Next: If wires are secure, proceed to the next step.
- Replace the OutletDo: If the outlet is damaged or not working properly, replace it with a new one.Observe: The new outlet powers on and works correctly.Means: The old outlet was faulty and needed replacement.Next: If the new outlet works, the issue is resolved. If not, consult a professional electrician.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Loose or damaged wiring Loose connections can interrupt power flow to the outlet. | Common | Easy–Medium | Wire connectors or outlet |
| Faulty outlet Internal damage or wear can prevent the outlet from functioning properly. | Common | Easy | Outlet |
| Tripped GFCI outlet A tripped GFCI outlet can cut power to other outlets on the same circuit. | Common | Easy | GFCI outlet |
| Circuit breaker issue The circuit breaker may not be supplying power to the outlet. | Sometimes | Medium | Circuit breaker |
| Overloaded circuit An overloaded circuit can cause power to be cut to certain outlets. | Sometimes | Medium | None |
| Damaged electrical panel Damage to the electrical panel can affect power distribution. | Rare | Hard | Electrical panel repair |
Parts you might need
When replacing parts, ensure they match the specifications of the existing components.
- Outlet: match the type (standard, GFCI, AFCI) and amperage rating
- GFCI outlet: match the voltage and amperage rating
- Wire connectors: match the wire gauge and number of wires to connect
- Circuit breaker: match the amperage and type (standard, GFCI, AFCI)
- Electrical panel: match the brand and model for compatibility

When to call a professional
- If you are unsure about any step or feel unsafe working with electricity.
- If the outlet still doesn't work after following all the steps.
- If you suspect damage to the electrical panel or wiring.
- If the issue involves multiple circuits or the main breaker.
- If you detect a burning smell or see signs of electrical arcing.
FAQ
Can a faulty outlet affect other outlets on the same circuit?
Yes, if the outlet is wired in a daisy-chain configuration, a faulty outlet can cause other outlets on the same circuit to stop working.
How do I know if the circuit breaker is faulty?
A faulty circuit breaker may not trip but still not supply power. Test it with a multimeter or consult a professional electrician.
Is it safe to replace an outlet myself?
Yes, if you follow proper safety precautions and turn off the power at the circuit breaker before starting.
What should I do if I smell burning near the outlet?
Immediately turn off the power at the circuit breaker and call a professional electrician.
Can a GFCI outlet cause other outlets to stop working?
Yes, a tripped GFCI outlet can cut power to other outlets on the same circuit until it is reset.
