SOURCE: ptac fan keeps blowing

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

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: 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.

I know this is late but I had to add a solution to this problem since I had the exact same problem and was able to solve it. The probelm is not your control board. On these units, the heat pump compressor will not kick in unless the temperature you set on the control panel is within 2-1/4 degrees (or 4 degrees depending on your unit model. Otherwise, the unit locks out the compressor until the electric heat coil bring the indoor temperature up to that level - and then will switch the compressor back on for heat pump operation. So the problem is not the control panel or the compressor, it the electric heat coil. The coil has two manual limit switches on it that may be tripped and should be checked. The coil can be easily accessed by shutting down the power, removing 4 screws around the air outlet, pushing the screen up and sliding the panel out the top. The power wires can remain in place while the limit switches are reset. Hope it works.

Amana PTAC PTH093E Fan runs at single speed only regardless of setting-auto/low/high Hot or cool air is coming out so compressor/heat coil is working. Reset unit and replaced fan motor-no change.


I've replaced many Amanda control boards. They have micro relays attached to the board. These relays are about a half inch by 1 inch in size, and control line voltage to the compressor and blower motor, and give up quite often. Its probably the board if its a digital controlled board. If it has manual, turn to select, type knob, it will be in that fan section knob. Hope this helps!

You said in another post that the error was c7. That means evaporator freeze. Too cold. That could be lack of air flow, bad sensor, ice on the coils.

2 problems.. AC Comp cuts out. And Fan will not stop.


Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!

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.
