CP5176 FET compressor / Re: Resistor R57 burned on setup guide ..

Swapping the power transistors was the issue; it's working now.  Originally I checked the orientation of each power transistor to the heatsink boards but not their designations and orientation to the DOA as a whole; I think the phrase "did you flip the power transistors" in the original SK25 troubleshooting post might have thrown me off.  Thanks for the help!

Try again after removing the DOA.
If back to normal then check the DOA.

The problem was on the DOA.

I've ordered one already made and tested from you and replaced the resistor, everything ok. Installed mine and it burned again, so the problem is on DOA..


Thanks for everything

I have the exact same issue; resistor 56 & 57 burning on setup guide step instructing to include DOA.  I have checked the DOA as instructed in the thread and don't have any of the listed issues.  Recommendation?
