has any one ever work on it? is there a timer on the board at the condenser after power has been shut off to bring the compressor contactor/condenser fan on? I shut the power at disconnect box and had to wait about 2 mins for the condenser fan to kick on. I already diagnose that it need a new board since I have no 24v at the contactor coil and new contactor since the coil has no continuity. I did not shut the air handler off so it has 24 v coming to Y and C terminal. look at the wiring diagram and it doesn't tell you jack of sequence of operation.... normal split AC would've just start as soon as you put power back on w/ call for cooling (after it equalize ofcourse).
