Question about Ruud UBHC Air Conditioner
I have a RUUD AC UBHA-17J15SFDA unit which was not blowing cold air for several weeks, I thaught because the weather, we were over the 100 degrees outside but I just opened the inside unit finding ice inside.
It is likely low on coolant or as some say "freon" that or the indoor fan motor has not run properly. let it thaw completely by shutting it off and just turning on your fan switch from auto to the on positon. if you begin to feel air flow eventually you need coolant added b/c you probably have a leak from the system being old

Also, check the evaporator coil (air handler coil ). If it is dirt, that tool will cause AC to ice up and prevents air to pulled through the coil which actuary causes the cooling effect.

Low temp setting and low fan speeds will permit the icing of the coils., so will a low refrigerant charge. Some people set the ac to cold cold and the fan to low thinking to just maintain a cool level all day. It is better to set the temp at a point of around 72 -74 degrees and set the fan at meduium to high. This gives the unit a chance. to cycle off and on periodically so it can defrost in the breaks. Icing is also an indication of a low refrigerant charge, but see if the fan temp settings help.do not have fan speed ontrols so you may have to call out a service tyech to chk the refrigerant charge.by all means, chk the condition of your air filters. Good Luck, Ned
