The stove suddenly quit working, with only the broiler still working. Upon investigation, the 3 prong stove outlet prongs inside of the outlet appeared to have been spread apart too far so the 3 prong stove plug-in was no longer making a good connection. He pushed the prongs inside the outlet closer together, now there is good contact again with the stove plug. But should I replace the outlet for safety? And What would cause the outlet prongs to spread apart inside of the wall? My feeling is the stove must have been unplugged by someone and then not plugged in correctly or jammed in or maybe when it was pulled out from the wall for cleaning, it was yanked.
