Carrier air-v AC is not blowing cold air

Check outdoor unit ,if the outdoor fan is spinning ,check if the compressor is coming on , if both fan and compresseor are working
it may be low on refrigerant

Possible indoor fan motor not working or if it's blowing air just not cold air then compressor not coming on on outdoor condenser

There is ice forming on the evaporator coils. This is either from a low freon charge or a leak in the seals or windows and doors. Could also be that the drains are not working and water is building up and freezing

The cooling light not coming on, on the ac unit

These units are known for not working too well even if the rear coil is the least bit stopped up. This is the first thing you need to check. Pull the unit out of the case, (unplugged) Peer through the rear fan blade and inspect the rear coil. The rear coil looks like a radiator. When it is plugged up with dirt, the unit will only work partially and will overheat quickly. The compressor may only work part of the time. If this is not the problem, you either have a compressor that has weak rotary veins (valves) or low on refigerant.

Cleaning the coil: The rear coil is screwed to a rear fan shroud. You can take these screws out and carefully pull the rear coil out enough to wash it out good with a water hose and sprayer. Be aware, there are two line of tubing connected to the coil . If you are too agressive pulling this coil out of the shroud you can break these copper lines or kink them causing all kinds of problems. So, be careful and take your time. Also, make sure you don't have a real high pressure coming out of the sprayer so that you won't bend the aluminum fins. Hope this finds your problem

TO LO OR HIGH!!! ALSO THE FILTERS COULD BE DIRTY OR AN AIR RESTRICTION IN YOUR RETURN AIR DUCTWORK OR DUCT IS NOT BIG ENOUGH.{ NOT ENOUHG AIR BLOWING ACROSS THE INDOOR COIL} IF THE UNIT ISEQUIPPED WITH A TXV THIS COULD BE CLOGGED AND WILL HAVE TO BE REPLACED BY A CERTIFIED A/C TECHNICIAN. FIND A FRIEND WHO HAS A TRUSTED AND HONEST A/C GUY... GOOD LUCK

Take it back or call Sears. A 2 week old unit should not do that. I'll assume the settings are right like set on AC Auto or Max cool and not just fan. Are the coils icing or were they icing behind the filter? If not, I think it may need to be serviced.

Go to the outside unit and see if the compressor is running. It may be hard to hear. If you need to you can disconnect one fan lead so you can hear the compressor. If it isn't running then check the capacitor. If it is running then get the refrigerant charge checked. Also check air filter(s) and make sure the coils are clean.

Check the outdoor unit to see if it is discharging hot air out of the top ofd the unit, check the insulated suction line to make sure it is cold or sweating. Try to listen to the outdoor fan and the compressor to make sure they are both operating

Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ
