Question about Amana In Wall Install Kit For Digismart Ptac Units - Wall Sleeve, And Grill
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.

Sounds like if this is a heat pump, maybe it tripped out on high pressure. Maybe just unplugging the system may reset the control boards. This maybe due to a dirty filter or dirty evaporator coil.

I have a Amana PTAC Model PTH153A50AC with the DigiSmart upgrade kit (DSUK01B) which as of last night stoped generating heat. I tried the Diagnostic and got a "LF" displayed. But I find no reference to what LF means. HELP please. Also I looked but can't find a reset button either.
House without heat
