How can I stop the oven door closing on me??

Maybe these kind of things would do the trick?

Shove a few £50 notes under it,hahahaha. It should have levels underneath I know mine has along with other white goods which are free-standing.

Had aimilar problem with washing machine in daughters house (rocking and rolling)
She has now placed a sheet of plywood under machine.
Found easier to get the wood level on uneven tiles.
The washing machine feet were much easier to adjust on a flat surface.

I had this problem in a rented flat. The oven door was metal and swung right back to the adjoining kitchen unit so I stuck a magnet to the unit with Command fixings that peeled off easily when I left.

When the oven door was fully open it attached itself to the magnet, if you see what I mean.

We used to live in a 17th c farmhouse without a right angle in the place and we had wooden wedges everywhere under furniture etc.
But doesn’t your cooker have self levelling feet (I know my fridge does)
