Not sure where to post oven troubles

So I have a whirlpool gas oven/stove.

Well my oven keeps turning on in the middle of the night. My oven is the type that have a buzzer that goes off when it is done preheating, so I know it hasn’t been just left on. Several times now it’s went of around 2 or 3 am not sure exact time but some time around there because I’m in bed around 12 or 1.

I am starting to get frustrated because a) it keeps scaring the crap out of my kids and b) doesn’t seem safe. Last night I unplugged it when it went off!

Any one have any idea of suggestions?

Sorry if I post in wrong place just not sure where to post! I’ve called a few appliance places but next to no where is open in my area and the people I did reach said they’ve never heard of this!
