Oh boy! That is a board unique to the single compressor units. IF you need a new board, the newell board will work, but you will only use half of it. Take a really close look at the compressor connecton, the neutral wire looks like it has been really hot. The original boards have several weaknesses. One is the soldered connection for power in; one is the lands on the back of the board are inadequately sized to carry the current; one is the inadequately sized connector for the compressor and fan motors.

I would pull the board at this point for inspection of the back side. The fixes may be simple if you are handy with a soldering iron.

If the board is totally cooked, there are some “options” other than the Newell board if you are comfortable with basic electronics.

In any case, while i am in there, all the start caps should be replaced
