Several days ago, GFCI receptacle in kitchen blew while Windex'ing ants, because they were coming out of the prong holes. My middle name is not Darwin, needless to say. 20-40 second period of rapid clicking, followed by a pop sound, followed by a puff of smoke, but no odors of burnt anything. Removed cover plate, all looked okay. Not sure what else is on that circuit. Haven't plugged in anything. All other outlets and loads working 100% correctly (which is odd if something else is on that circuit).
If that GFCI were the only load/receptacle on that circuit (granted that is unlikely), how urgent, if at all, is replacement?
Edit from OP:
I plugged a floor lamp into the GFCI. The outlet works. I found the controlling circuit breaker. No other kitchen services are on that circuit. The circuit appears to be dedicated to that one outlet, however, ts just a normal wall outlet about 8" above the counter, under the upper cabinets. The microwave is above the range and is on a different circuit.
I'll still DIY replace the outlet, but my take at this point is the the GFCI worked as designed (clicking noise), and that the puff of smoke was not smoke, but shorting drop of windex vaporizing away, which leads me to conclude, in short, that there was/is no urgency and that replacing the GFCI is highly likely to be overkill.
