Dual AC have Error code E4 on unit1.

Need help fixing unit 1 AC with E4 code. Tried reset of thermostat, removal of fuse, unplugged everything and still get code. Is mother board bad in AC unit?

Is the trailer plugged in? Is the breaker for the a/c tripped?

Pretty sure that's the code I see on the thermostat whenever I have tripped a circuit breaker on the AC panel.
