An old oven (20+ years) plugged into an 220v 3-pronged outlet suddenly caught fire when we tried to use the oven a week ago. We replaced the appliance today but found that it would not power on when plugging it into the outlet. I took a look at the circuit breaker but there was no tripped circuits. I turned off/then on all of the circuits and, after plugging the new oven in again, I get power (clock on oven turns on).
My concern is that the fire was not caused by the appliance but faulty wiring and I was hoping to get some advice on whether this is safe or not. If it helps, the home is from the late 60-s and the outlet itself is not GCFI.
Thanks in advance!
