Either the new control board is faulty, or the connections are bad, or the issue is somewhere else.

The main problem is that you are not an air conditioning / heating engineer. Some things are not home owner fixable.

FUJITSU Inverter wall mounted split air conditioner Model : AST12LSBCW not working, flashing lights

This is a "PFC circuit abnormal" in the outdoor unit meaning that the outdoor controller board is faulty. Try turning the machine off at the isolator switch for 10 mins, then back on to see if the error resets. If not you will need a new controller PCB.

No power at interior unit. power everywhere else

If this is a mini split ductless there is a control wire with 3-4 wires inside (normally red, white, blue and green) that is connected from the outdoor unit to the indoor unit. This wire feeds voltage from the o.d. unit to the I.d. unit. If all connections at the o.d. unit are good, then check for voltage at these connections at the o.d. unit. If no power at these connections then a circuit board has faulted. Call a tech. and have a tech support number ready (1-800#) in case your service tech don't have it.

The unit either encountered a brown out or a surge which burned up the board for the condenser. It had black marks on the board and the indoor unit was flashing. Replaced the board and the unit is still...

After replacing the burned condenser board, check also the entire condensing unit if still ok ( compressor and fan motor). If the light inside the indoor unit is still flashing, the timer is still not giving signal for the compressor to start. Adjust temperature and wait for 3-5 minutes. It light continue flashing, there is something wrong with the indoor unit control.

My Amana asx 16 seer 4 ton system installed 3 years ago quit working. The alert light is flashing 6 times. What does this mean?

Hi if you are looking at the indoor unit and this is where you see this flashing light, remove the panel. The circuit board is where this led light is. You will also have a 3 to 5 amp fuse plugged into the board. Look for a chart on a panel door. It will be glued there. It will tell you what the problem is according to how many times it flashes. Could be several different safety switches. Make sure there is no door panel switch on the indoor unit, has if there is, the unit will not run after you remove the panel, it kills power to it. You may need to tape it down so you can have power to run it and check it out. Is the indoor unit a gas system or is it a 4 ton heat-pump? If you cant find what I have said, get back to me after checking these things and let me know . Check all breakers. Let me know if this is a package unit or a split, indoor and outdoor unit, or all in one. I will wait to hear back from you on this.
Sincerely,
