Unplug the power lead from the AC compressor.If it stays locked up it a mechanical issue with the new Clutch. If it unlocks check the following. Look at the AC Relay. If it has fused or failed in the closed position the ac clutch will remain engaged. As I don't have the vehicle details I can't provide further details
Most generally the original circuit board has a model number on it that should be the same as a replacement board. If it does not match, then you may have the wrong replacement. Why did the board burn up? It may have caused a short that you have not diagnosed, thus possibly shorting out the new board. The fan stays running because the call for cooling is not satisfied.
it's either low (in spite of your readings) or your a/c clutch is not working correctly or you have too big an air gap in the clutch.
First, just disconnect the 2 pin connector from the a/c pressure cycling swithc and jumper the 2 pins with a wire to force the clutch to stay engaged. See if it blows cold then, and stays engaged. You can run this way for about 15 minutes before you have to pull the plug.

first discharge the capacitor for safetys sake,then touch the meter leads of a multi-meter set to RX100 to the caps leads if the needle stays on 0 the cap is shorted(but that would trip the wall breaker),if it doesnt move at all its open,if it goes to 0 and slowly climbs back towards infinity its good,i believe you will find the ptc overload relay on the compressor is defective,its in combination with the capacitor,the cap is only on there to take the power spikes off the relay contacts during start-up,the ptc overload relay is what aids in compressor start-up/run/and overload protection if compressor wont fire,change them both and it will run
One of your fans works off the coolant temperature sensors input and will only engage when the coolant temperature reaches and/or exceeds a certain preset degree. The other runs off of your a/c compressor and when it engages so will the auxiliary or secondary cooling fan. Start the engine cold, turn on the a/c and listen for the secondary fan to engage then as it warms up listen to see if the primary fan engages. when it reaches running temperature. Please rate me on this answer.
Check your gas filter. When you ran out of gas, you got any rust in your lines and filters. Change the inline filter and use an air compressor and blow the line TOWARDS THE TANK. Take the gas cap off first. There is also a filter in your tank.By blowing the line you may unstop that filter.
