How do I remove cover from fridge temperature...

Question

I need to replace the thermostat on my fridge but can't see how to remove the cover off the fridge temperature control panel (the thermostat is housed behind it). There are no visible screws and I'm a little unsure as to whether to try removing (pulling off) the temperature control dial to see if there's a s***w behind it as I'm not sure whether it's supposed to come off. Can anyone help?
