A power outlet that’s slightly warm to the touch is not uncommon during heavy use, but it can also be a sign of danger.
If you suspect a problem, run a quick check.
- Start by unplugging any devices that are using the outlet, and then feel it again. If the warmth disappears, the problem may be the appliance or a loose plug. Test the device on another outlet.
- If the outlet remains warm with nothing plugged in, do not use it. That suggests loose wiring, a failing receptacle or an overloaded circuit. Call an electrician to diagnose the trouble.
- Never use extension cords or ungrounded adapters as a long-term fix. Limit high-draw appliances, such as space heaters, hair dryers, microwaves and portable air conditioners, to dedicated circuits, and never run space heaters from a power strip.
- If you see discoloration, smell burning or notice sparks, shut off power to the circuit and call a licensed electrician.
- Once the outlet is fixed, avoid over-loading circuits and consider a professional inspection of your entire electrical system.
