Vent, Valve & Volt
Light switch, dimmer or outlet warm to the touch

This one needs a licensed pro

Likely cause: a heavy load on the outlet

Heaters, hair dryers and crowded power strips pull a lot of current. Unplug it. If the outlet stays warm, turn the breaker off and call a licensed electrician.

Why this happens

Family Handyman flags high-amp devices and overloaded power strips as a cause of outlets heating up, and says to shut off the breaker and call a licensed electrician if the outlet is hot. CPSC says an outlet may be warm but should never be hot or discolored from heat.

What to do right now

  1. Unplug the heater, hair dryer or power strip, gripping the plug, not the cord.
  2. Wait a while and feel the outlet again.
  3. If it is still warm, or it was ever hot or discolored, turn its breaker OFF at the hinged panel door and leave it off.
  4. Call a licensed electrician before you use that outlet for a heater or other heavy load again.

When to stop. Any burning smell, discoloring or crackling: breaker off now.

What to tell the licensed electrician

  • What was plugged in and for how long.
  • Whether the outlet cooled after you unplugged it.
  • Whether the plug fits snugly or wobbles.
