When you refer to the intake grill, what are you talking about and where is it located? There is a return air grill that will never ice over and there is an indoor coil that can ice over. If you are referring to the evaporator coil, the reason it is icing over could be 1. Dirty filter 2. Not enough air blowing accross coil 3. Low on refrigerant, which indicates the system has a leak. Check the outdoor unit and see if hot air is blowing off the top of the condenser fan. If it is cool, you do not have enough refrigerant in your system and probably have a leak. Call a service tech to check your system.
