How do you get the cover off the switch for the light in a GE refrigerator?

The light will not work in our GE refrig. We got a new bulb but it still doesn%26#039;t work. How do you get the cover off of the light switch to change the switch?|||first i would unplug the frig and check the socket, it might have corrison from moisture in it not allowing the bulb to make contact to light up.....otherwise the switches 99% of the time snap into place you just need to pry it out.....but if you don%26#039;t know how to do that i would call a repairman
