My 4.5 yr old free standing, double-oven LG gas range was not in use at the time of the incident. I heard a bang and went into the kitchen - saw nothing.
Heard a louder bang and went back into the kitchen. The "CL" clock rest on the range was displayed and black, acrid smoke was coming out of the control panel. I pulled the plug and called an electrician.
He examined the outlet and said it was fine. Luckily we were home at the time of the incident or the house may have burned.
