I have a Crown RC3020-30 that is doing a hard plug both forward and reverse, sometimes resulting in a PMT to where you have to turn the key off and back on to reset. I have replaced both Fwd/Rev contactors, the plugging contactor at the bottom, the 4 REC B in the contactor panel, and tested the 4 REC by the control board. I have also changed and adjusted the forward reverse switches for the off chance that was affecting it. If it is turned either direction where it drops out one of the motors, it doesn't do it, but both motors seem to be in good shape where one of them is fairly new within the last couple of months. Any other ideas?
