[image|2451363][image|2451362]My samsung side by side model RSG257AARS stopped cooling on both sides. Gave me several codes upon entering diagnostic mode. A sensor, a fan motor (even though both fan motors were operational upon inspection) and P<->M communication error. I tested voltage at CN79 and only had 1.89 V DC across the compressor signal pins instead of the 2.5 V DC specified. I also only had 10 V DC across CN76-5 instead of 13 V DC specified. I'm used to working on a little more simple units and just needing some help diagnosing. Are these readings off of spec enough to call this a bad pcb?
