Condenser fan motor was running slow. This was not a problem included in your list of possible problems. I thought that maybe the capacitor was bad but have no way to check it. So I ordered one. when I received it, I installed it. That was not the problem. So I ordered a fan motor and installed it. That was not the problem. So finally I ordered a control board and installed it. That solved the problem. So maybe you should put "cond.fan motor runs slow" in your list of possible faults and what causes that problem. Capacitor was easy to install, simply remove the cover plate, flip off retaining wire, unplug the capacitor and replace. Fan motor was a bit more difficult. It must be removed from mount after fan scroll is removed. Remove one screw that holds scroll, bend the top down and remove. Then pull hard on fan blade to remove it. It must be installed on new motor. Two screws in frame mount can be removed with some effort if you have a 1/4" drive ratchet with a Phillips screwdriver bit. Then pull frame open and install new motor. Push fan blade on new motor shaft hard. Replacing control board was easy. I used a pair of long nose pliers with 90 degree bend to get mounting pins closed to pull board off.
