if you have it set at 60 F and it is working at 65 to 68 F then that would be about right
as the air is cooled the cold air falls to the floor and out under the door, open window or anywhere else it can escape
the unit has to be at 80% room height so if it is set in a window then when the cold air gets up to the thermostat or ac level in the window then it will stop cooling
So if the ac unit is say 4ft from the floor and the ceiling height is 8 ft then the ac will only cool the bottom 4 ft
cold air does not rise but falls down
if you are using a ceiling fan then the cold air is stirred up and the 65F sounds about right
remember that the setting temp ( what you set it at) is the lowest temp that it will go down to before it stops cooling and if that is not reached it will keep working to attain that temp and if the room is too big, air leaks under door . around the fit in the window , no insulated walls , hot exterior wall,etc then maybe 65 F is the best you will get
Sounds like it could be low on freon I believe these units have about 1.5 pounds of freon in them and are critical in not undercharging or overcharging them if it is a freon 410 ac unit the pressures should be about 135 and both lines cold if is low on freon a service tec will need to be called to try to repair the leak if possiable
Make sure the filter and the evaporator coil are clean. Also check condenser coil in the outside unit is clean.
When unit is turned on there should be (on the led display, inside unit) one green light on for the blower and another one for the compressor, both lights should be ON untill the unit reaches the preset temp. If the light for the compressor (usually the light on the right side) does not stay ON, check the outside unit.
On the outside unit, check that when turned on, both the fan and the compressor kick in and stay running. If the fan motor stops, the compressor overheats and the thermal proteccion shuts it down to prevent damage. Also, if the R22 gas is low, the low pressure switch prevents the compressor from running.
Remove the window unit and dissasemble,and clean it out,careful not to bend the fins on the condense and evaporator,but clean them out,and the inside of the unit also,then see what happens,if the problem persist,then find the probe on the evaporator and move it away from the evaporator until the compressor stays on longer.
undersized is just that...you and I got taken to the cleaners.but i did put an adjustable vent in the cod air return vent duct next to the floor...it helped mine but i say some installers should.....well you know
Position A, Cool 70-78, Heat 65-73
Position B, Cool 68-81, Heat 68-76
Position C, Cool 66-83, Heat 61-78
Position D, Cool 63-88, Heat 58-83
Amana calls this a Temerature Limiter and says to only set one switch on at a time. If all switches are off then the unit is at full operating range.

Mine was doing the same thing and it was really frustrating! I would come home and it would be 88* inside. I found out that this model air conditoner has had problems with moisture getting in the control panel and shorting it out when it's humid outside. I have the part number if anyone wants it. It cost me about $45 from Sears Parts.
