The temperature controls in most fridges really get my design goat. Are they a thermostatic 'temperature' control or a 'power' control? They're not giving anything away! If I want my fridge to be colder should I turn up the control to 5 for maximum cooling power, or turn it down to 1 as in 1 degree centigrade? Labelling it 1 to 5 is just begging for confusion. If it's truly a thermostat (and well enough calibrated) then make it clear with 'c' markings. If it's a power control then make that clear with "cooler" / "warmer", red / blue gradients or something. Perhaps I need to buy more expensive fridges with digital thermostatic controls.
