Make sure you have the temperature set right. We keep ours set at eighty degrees. It helps if the thermostat works correctly.

Turn off the unit and let it thaw out for 24 hours. When it is dry and completely free of ice, get an HVAC technician to repair it.

Check to see if there is something restricting the air flow through your cooling coil. The return line to the compressor will be frosted if it is restricted.

never set the temp below 68. if you do drop the temperature a few degrees at a time to keep from overworking the system

If you are referring to the heat dissipating grillwork on the outside compressor, the problem is that you are low on refrigerant. Have it serviced by a professional.

Turn your unit off, but turn your fan on. Let the fan run until it melts the ice away and then your unit should be good to go.
