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!

Formula to calculate rating of capacitors in
It's not fixed formula, but as per basic rule, easy method tocalculate for motor capacitor.
(2650 X full load amps) divided by supply voltage(mentionedin capacitor)= MFD. (Plus or minus 10% to 15%)
Ex: 1 Tr which gives full load amps of 6 amps (2650 X 6)=15900 divided by 240(VAC)volts=66.25MFD
(10% to 15% plus or minus) You can fix 56.32 mfd or 76.18mfd
So, you can go in between 56.32 mfd and 76.18 mfd.
If you calculate of 440VAC capacitor, it will be 36 mfd.
Hope, it will be helpful . Thanks.

I have an Amana ptac hotel type thru the wall
If you reset the GFCI button and then when you go to turn it on the button pops again, then you have a short inside the units probably in the fan motor or the compressor..

My heat pump is shot and is operating off the
You mean you are using the Emergency heat setting instead of the heat pump????...You're using Natural gas only now tn emergency heat????That's fine...I wouldn't replace a heat pump if you have Natural gas....it's too expensive compared to Gas....you may be able to still use the heat pump as an Air Conditioner only , it depends on what's wrong with it...otherwise you will have to get a Central Air unit instead...cheaper and just use the Gas for heat

Fan runs all the time and no heat
br means brown out protection engaged. Power was lost or voltage is to low, check for incoming power at correct voltage

Heater, ac and fan speeds all working fine. Compressor not kicking in...just auxiliary heat working.
Outside temp too low, so outside thermostat and it's settings will not allow the heat pump to work. But insist on the ausilary heat to work instead. Heat pumps usually do not produce enough heat when below 40F outside temp. If you have Gas heat, it may be more economical than the heat pump below 40F. If electric auxilarry heat, it may compete at 32F. Talk to your dealer, installer, or manufacture.
