Riddle me This

If you're comfortable taking the cover off your load center (panel) check all the wire terminals on the breakers. Then check all the ground and neutral connections.
Stove connections are very prone to getting loose with time due to stranded wire and extended load time.

That too. But I'd be more interested in the connections at the stove. I've seen burned/broken connections there.
Brian, can you take a picture of the outlet for the stove for me?

Had a few pokes but nothing too bad. Rental had a electrified cast iron sewer line somehow.

Not licensed but experienced and love a good puzzle. Ran into something similar once. Subpanel at patio? Ground and neutrals cannot be mixed and must be separate.

I'd take covers off and post pics.

Especially a subpanel. Though, it is a good practice on all panels even if the ground bar isn't isolated.
