The fan probably needs to be oiled? just stops

Is your indoor fan running also? If not, your condenser contactor has welded shut and needs to be replaced

Serial communication error. This means that the indoor unit is not communicating with the outdoor unit usually because the outdoor unit is faulty. You can check the indoor unit by switching it to 'fan' mode and seeing if all functions work normally (fan speed, louvers move as directed). If it responds normally, then it's probably ok so you can turn your attention to the outdoor unit. A common problem with the outdoor controllers is that they are susceptible to bugs, geckos, etc. shorting them out which will mean replacement of the board.

I have had similar problems with Samsung. Apparently, the indoor board fits a lot of different models and each has to be "programmed" in to suit your model. Not sure what was wrong with your machine before but it has been known for these units to have a faulty outdoor fan motor which causes the outdoor board to fail as well. When this happens, the indoor unit will usually work fine for about a minute or 2 and then shut down, with lights flashing. The outdoor wont start at all. If these were the symptoms, I would suggest putting your old indoor PCB back and then getting a new outdoor fan motor and outdoor PCB.

Signal transmission error. Indoor and outdoor PCB's cannot communicate. Usually a faulty controller board in the outdoor unit. If the indoor unit otherwise functions normally (can control fan speed, louvres, beeps in replay to all remote buttons) then it is probably OK so check outdoor controller PCB.

Yes it rated for a maximum out put of 36,000 btu (3 ton) with the right indoor fan coil units which based on the model numbers should give the 36,000 btu's combined when both fan coil units are on, otherwise 18,000 btu's (1.5 ton)per fan coil.

The indoor fan will not run at normal fan speed untill the indoor coil reaches 32oC. This is done so that a cold draught is not felt when outdoor unit is not running. Check to make sure the outdoor unit is operating. If the outdoor fan is running but there is no indoor fan after 5 mins then you must likely have a gas issue or a fault compressor circuit.

I have had this problem with a Fujitsu unit before. If the power is supplied to the outdoor unit first but unit is meant to have power supplied to indoor unit first, outdoor will only stop when power is cut off! In that case, you will have to run the power cable to the indoor unit first and then connect from appropriate terminal back to outdoor unit. (Often the indoor will stop outdoor unit by just cutting the power to it via use of a relay on the pcb.)

You can probably find outdoor blades at Home Depot, Lowes, etc.

There are ways to reduce the warping of indoor blades, but it's too much for most people. I'd suggest replacing them.

You could also surf the net for Hampton Bay stuff -- might be able to find them there, too.

Does the indoor blower come on? If not you might have a low voltage problem in your thermostat circuit or blown breaker or fuse for your furnace which energizes the contactor outdoors. If indoor blower runs check if their are any fuses in your outdoor disconnect.

I need more information. And if you have worked on AC's before? Thes main things to check I believ is the fan motor I just wrote out a long explanation as to what to check and look for and I think it got lost. SO I believe your hearign the compressor continue to run even when the fan stops. 
Eventually the compressor over heats and stops. this is when nothig runs. Here is where I believe te indoor coil has been covered with Ice-frost and when the compressor stops the ICE FROST melts and you get water on your floor. 
The motor could be bad or the run capicator  I also believe your indoor coil (and most likely the outdoor one too) is plugged up or dirty. A dirty outdoor coil is the most often cause of motor over heating and or capicator failure. If you can look through the fins of the outdoor and indoor coil ALL OVER then they are clean. Any area stopped up over 20% and you need to wash them out.
Take your capicator out and have it checke by someone with a capicator checker. They will most likely have a replacement if needed. Check the "STIFFNESS" of the motor bearings. If you spin it and it turns over 2 or 3 times or more the bearings are probably ok.  If it has oil holes add about 20 to 40 drops lite machine oil to the bearings. If they are sealed... Start looking for a repairman or take care if your goin to change it yourself. Too many factors to go into here about changing a motor. And some may or maynot apply.
Hope this helps you if I need to more clear get back to me and well discuss it more. GOOD LUCK!
