My Goodman DSZ160361AE doesn't run. When I start it up it will run for about 4 seconds then shut off. I get an error code of 7 yellow blinks which means run circuit or compressor windings
The unit worked for 5 months then the circuit board burned up along with some of the wire harnesses. I replaced the board and harnesses. When I turned the unit back on it tried to run for 4 seconds then everything shut down and I got the error code. When I unplugged the power plug from the compressor the fan on the unit will stay running, but when I leave the power plug in everything shuts down. So I replaced the compressor and the run\start capacitor and the hard start cap. I still have the same problem. I don't know if I have a bad circuit board or the wrong one. It seems the run circuit is the problem but I don't know. I also bypassed the high and low pressure switches to see if that was the issue, nothing. Any ideas what I can do from here

Get rid of the hard start cap. Hard start capacitors should never be used in conjuction with normal compressor operation. Contact your local dealer for goodman and find the correct dual capactor for your machine and install it. Odds are your dual capacitor is either not functioning properly due to over voltage strike or it is the wrong size. On the wiring to your compressor, black is normally common and lead directly back to your main contactor. The red wire is the running lead and again normally goes to the c connection on the dual capacitor which leads back to the other side of the main contactor. The remaining wire on your compressor goes back to the herm connection on your dual capacitor. You may have swapped the wires for your power supply to your capacitor. I did this once and I figured it out about 5 hours later after I performed a wire by wire check against the wiring diagram. If you switch the wire around you turn the start windings into run windings and vice versa. They are not designed to be interchangeble. Just check your wiring against the diagram and the problem should clear up.
Hope this helps.
