Question about Heating & Cooling
I have an Amana PTAC model PTF153A50AA. Recently it starting kicking out after running for several hours. Now it will not come on except on the fan setting. Could this be the thermostat? I can't hear it clicking anymore when I move it.

Most likely you will need to either replace transformer or there may be a low voltage flat type "car fuse" usually 3 amp or 5 amp for just such an occasion. Good luck!

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.
