Amana PTAC PTC093A35AA won't blow heat

The heat has gone out on my Amana PTAC unit. I've unplugged it to reset it, but it won't work and I can't find the manual reset button. Please help me locate it.

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.

My amana ptac is not heating....the code "np" is displayed....how 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.

I have a AMANA PTh153B50AE (PTAC unit). The air conditioner works fine. It is when I turn on my heater and it does not get warm. It just blows cold air. I have looked at the board and it appears that...


I have the same problem, and I found the manual reset inside the unit. Turn the power off, and unplug the unit. Remove the outer cover of the unit ( inside cover ) , and remove the 2 screws holding the " wire mesh " in the front of the cover. Pull the wire mesh up and out of the way, then carefully pull out the heating element.
On the heating element, where the wires are connected, there is a manual reset button... Push the button in, till it resets...

My reset was on the upper left connection of the wires... just looks like a small push button, but the reset is recessed a bit.
Replace all covers and plug back in.. working fine..

Amana PTAC


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.

Ptac fan keeps blowing


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