Thank you for your detailed response! I will check to see if the outlet is on the same circuit breaker as out oven. I absolutely would not plug anything else into the same outlet. This is the actual plug we got (which is big enough to cover both outlets so no one accidentally plugs something in.)

Unfortunately we are renting right now (short term, but may have to extend) so not an option.
Do the single GFCI plug adapters on Amazon work? I am not an electrician so I have no knowledge... Haha
