The oven wasn’t turning on, the clock and display were lighting up. I think when I turned the cooktop on, 120 volts was backfeeding to the oven display thru the common 220 volt connection.
The clock runs off of 120v. And again that shouldn't happen. If you connect 120 to the stove, then run the same connection off of a leg to the oven, it shouldn't come on based on the stove's activity. I'd still check the polarity, but that's just me and I borrow trouble all the time.

If that stove or oven ever shocks you though, it could be a hum dinger!

If it's a digital clock, it takes less than 20V (possibly less than 10) and only a tiny amount of current (milliAmps). The clock and stove probably share a common neutral that may or may not be earth grounded. Stranger things have happened.

You might also check for voltage between the stove's frame and a known earth ground (metal sink with copper pipes, etc.).

Agreed. Checking voltage from the stove and a ground might give you an idea of if the outside is hot.

Not an electrician either, & this may well not even apply to your situation- but I have 'fixed' several appliances ('newer' ones, with chips) by simply unplugging them & letting all that annoying computer crap 'reset' itself. It's always worth a try, & often solves the issue.
Also; I have an older washing machine that was given to me, but it suddenly decided to give me a little electrical shock whenever I touched wet clothes or the water in the machine...kinda annoying. Turns out, the problem was with a 'safety' plug that was between the cord & the socket it was plugged into. After tossing the darned thing, & plugging the washer directly into the wall socket- it's worked fine ever since. Apparently, this is a common thing.

Same damn thing happened to me! It went 10-7 into the trash.
