Reset the unit to factory setting by take the master switch off of 10 sec.
Then press and hold the cool and heat button down while turning the master switch back on.

IF the fan continues to run in the OFF position   It possibly could be the switch if this is the one im thinking that it is....the solution would be to replace the board being the switch is built into the board.    But if you are refering to the fan not turning off with the compressor then yes turn the fan cycle switch to auto/cycle.

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

Amana Wall unit blows cold air before heating


The cold that you describe may be just unconditioned air? If you are certain you can hear the comp operating for a couple of minutes, and then the heat starts, I would guess it is a reversing valve issue if it's a heat pump and it probably is. Or the control board acting up. I've had a lot of issues with the boards in the Amanda PTAC units. I can't remember how to configure it, but if you Google "Amanda ptac configuration", there is a lot of info online. May try a reset method first. Hope this helps!

Assuming this is a heat pump I'm guessing you have a bad temp sensor. Your outdoor fan is likely controlled by a temp sensor so it only runs as needed during heating. Fan not coming on and compressor still needs cooled therefore compressor protection kicking in?????

Amana ptac- blows same temperature air whether its set at 80 or 65...any ideas?


Check to see if your compressor is running. Thre are 5/16 screws on either side of the unit holding it to the case. Take those out and you can get to the cpmpressor. These are not complicated units but you may have to have a service tech look at it for you. I do sell a lot of these PTAC units so if your compressor is running you have leak or bad compressor. Russ

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.

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!
