Temp is set at 68 and changing the fan control has no effect on fan speed
Change the thermostat wire , if not change your board.

Try setting the fan control to "AUTO" this will cause it to cut out with the compressor.

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.

your control board is shot and your ac can't tell the room is cold enough. 1-888-855-9987

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.
SOURCE: looking for manuel reset on heater amana ptac
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.
