First you have to hit the plus(more heat) and minus (more cool) and hit off twice then the unit should show c1 and wait till it shows L5 the hit the plus sign till you get to zero then hit off.

My amana ptac is not heating....the code "np" is do I correct this...we just installed the unit and know little about operation. Thanks

I don't see this error code in the manual. I do see nP as an error code for Window Switch lockout. I just had this happen to me and they had me reset the control board.

Remove case, flick master switch to OFF for 10 seconds. Press Heat/Cool same time turn switch back on HOLD until off light comes on.

You should be fixed. Just had to do this for my unit. I was playing around with the settings and turned on the window switch option by accident.

Installed Amana PTAC DigiSmart unit in a patio room, a entertainment bar is located about three feet (3) in front of unit and not the room. The unit only heat and cool the area between unit and the bar...

I have seen this happen many times and if you cannot relocate the bulb of the thermostat to keep it form short cycling, I have mounted a wall thermostat and disconnected the thermostat in the PTAC and wired it in to the wall stat. You may have to install a wall stat in the center of the room away from the bar.

I have an LG AC and the lowest temperature setting is 60 degrees

Lowering the temperature setting doesn't change the temperature of the air coming out of the unit it just lets it run until the room temperature gets colder. Check the temp of the air coming out of the unit. If it isn't as cold as it used to be the charge could be low. First though you should make sure the filters are clean and the coils.You should also check the actual room temp. It's also possible the unit doesn't have enough capacity to keep up with the cooling load of the room.

Need to know what the settings are for the range adjustment A,B,C,D slide switch on the front panel on a Amana PTH123A35AC PTAC

Here they are;

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.
Please rate this answer to let me know if it was the fix.
