I have a FEDDERS a/c unit, model CKF036A7A, serial #CP175732. The coils inside the air handler are not getting cold. This happened overnight. Both units, indoor and out seem to operating as they normally do. What can be my problem?

We know that there is power at the outdoor unit because the outdoor fan is running.
I suspect that the compressor is NOT running. If you can reach it and touch it you can see if it is hot at the top and bottom or at same temperature as its surroundings (Ambient temperature). If it is hot, it may be off on a safety device or have a damage wire or contactor switch. If it is hot and running you may be very short of refrigerant or have a non-pumping (broken) compressor.
The indoor coil could be iced up if the compressor is running and the top of the compressor is cool or cold. If so, check your filter and defrost the coil to check it for dirt as well.
