Outlet not working?

First, find out why you had arcing and correct that problem. Then, inspect the outlet for any unusual burning or melting or loose wires. Lastly, go to your circuit breaker panel and reset the circuit breaker. 

look on the outlet itself for a small reset button. If there is one, push to reset.  If there's not, turn off power to the kitchen outlets and remove the problem outlet.  If you see any thing at all that looks discolored, replace the outlet.  If the cord for the iron is not "factory installed," you should look at it and likely replace it, too. 

Check all breakers or fuses. Be sure. Look for GFI outlets anywhere you could come in contact with water such as sinks bathtubs , outside or garage. Test each one and reset. Check your out let again. If it still doesnt work pull outlet out and check to see if the voltage is available at the outlet. If it is then replace the outlet if the connections.are tight and the wires are not broken. If you are not comfortable to work on this call a electrician. Grampa B

You seem to have isolated it to that one outlet, so I doubt if it's a breaker that has popped. Still worth checking, though.

Most likely a problem with the wiring behind the outlet, maybe a failed/burnt connection. I know you'll ensure the power is OFF before you do anything to it.

circuit breaker probably popped off. and if that's not it, the most likely cause is the wiring behind the outlet needs to be repaired

If you do not have a clue working with electricity, please call a licensed electrician.  You can DIE working with electricity.

If the fuse didn't shut down, you probably had a small electrical fire in the outlet. Probably the connection of the wire to the outlet screw was not that good. You should have sufficient length of wire to restrip the end and you will also need a new outlet. Get the kind where you stick the bare wire straight into the hole and a mechanism holds the bare end securely. As opposed to the screw type that is hard to fit.

Outlets in kitchens are often protected by a ground fault circuit interrupter (GFCI), a kind of mini-breaker that is super-sensitive and super-fast acting.  The switch is right there on the outlet itself.

Ask your wife to check to see if the GFCI (if it's there) is tripped.  If so, just reset it by pushing the appropriate button on the outlet.

If it won't reset, the GFCI may be done.  That happens, they wear out.  Part of what makes them so fast-acting is also what makes them way less durable in use than regular outlets.  But no biggie, they're only about $12-20 and no more difficult to replace than any other outlet.

Not a GFCI?  Check the breaker.  Usually a breaker will protect more than one outlet though, so I'm inclined to think GFCI.

Go look at your circuit breakers first. See if one is tripped. If it is, reset it.
