Amana ptac is blowing cold air ot with heat on and showing FP code

SOURCE: amana ptac shuts on and off constantly

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

SOURCE: ptac not heating

the board or the heater need to be replaced

SOURCE: Amana PTAC PTC093A35AA won't blow heat

The reset button is located behing a panel on the front of the unit that is labeled Heat Reset. If that label is gone then look around, it is a small hole, small enough for a paper clip to fit through.
That being said, I have 137 of these units in one of my hotels and have not had a single one needing to be reset. You probably are going to need a new control board kit. These can be purchased from Amana. They are $130. Make sure that you have pulled the heater coil out and inspected it first. Also, there was a recall years ago where Amana was supposed to contact and send out new voltage switches. These are the round black things that the Brown heater wires connect to on the upper and lower side of the heating coil. You should also try to replace those if you find the coil in good condition. I have had those resolve heating issues. Most of the heating issues were a result of a bad relay on the control board though.
Please remember to rate this fix.
