I am thinking of gluing the knob of the fridge in a fixed position.
A lot of guests set it on the coldest setting, causing it to freeze up.
Yesterday I found a puddle on the floor, destroying one of my cupboards because a guest put it on max and let it freeze up. Normally the water should go down a little drain in the back, but even that one froze up completely, and the cleaner did not notice this.
The problem is that there are still people on the world that think, that setting the fridge lower will cool things faster.
Like some people think that putting a room thermostat higher, will make it warm up quicker…
