Why is one outlet dead when the breaker is on?

Urgency: urgent
What this means
Check nearby GFCI reset buttons and wall switches without removing the cover plate.
Safe checks
- Test the appliance elsewhere
- press Test then Reset on accessible GFCIs
- check whether a wall switch controls the outlet.
Stop and get help if
- Do not open the outlet. Call an electrician for heat, arcing, burning odour, water exposure, or persistent failure.
