Maytag M7Y15F2A fan is working but no cold air is coming out

SOURCE: Maytag M7Y15F2A-D A/C - won't turn on -long beep then nothing

The beeping might be an alarm that indicates the coils are iced over by too much humidity in the air...and/or the unit is overheating etc.
shut off power to the unit for a few hours, go out somewhere if it is too stuffy inside.. see if the unit operates better when you return... I also suggest not running these things constantly, this causes some units to ice up and **** up the power..
hope the unit does get replaced, newer ones are more efficient.
