It has to completely thaw first. If indoor fan is running and the filter is clean it is freezing up because of a lack of refrigerant .

Short of gas, have it refilled

either the inside coil is dirty or system is overcharged.

there is a leak and need to fix it before you can charge it

unit is freezing up because it either has too much freon or not enough. the pressure should be checked on both the low and high sides and corrected.

SOUNDS LIKE THE FAN SPEED MAY BE TO LOW SO AS THE AIR GOES THROUGH THE COIL IT WILL START TO FREEZE HAVE SOMEONE CHECK THE FAN SPEED MAKE SURE IT IS ON HIGH ALSO MAKE SURE IF THAT IS THE ONLY FILTER ON THE SYSTEM

The contactor on the outside unit is sticking and must be replaced. The inside unit cycles off and the outside continues to run causing the refrigerant lines to freeze up.

Do you have any frost on the lines going to the outside unit. If the large line is frosted your evaporator (Cooling coil in the furnace) could be frozen up. Operating it with the fan in automatic with the cooling on will sometimes be the cause of this condition.

If there is not frost on the large line going to the outside unit and you are getting air circulation inside the house the problem could be a loss of refrigerant charge. Look at the joints where the pipes were soldered to the inside and outside units for signs of oil. If you find oil at any point it is the indication of a refrigerant leak.
