side by side not cooling (both sides) but no ice on coils - not sure its te compressor
i posted this problem 2 weeks ago and had some good advice and some bad advice, but i still have a question.... here is the original post"
"Both freezer and fridge stopped cooling suddenly. no ice on coils. fans are running, lights work. i've read about the adaptive control board and see there is a way to test it by jumpering two points forcing it to go from compressor mode to defrost mode. i am hoping there is a way to test it to go from defrost to compressor mode, since the compressor is not running. also, do the fridge and freezer have separate thermostats... if so, the thermostat(s) are not the culprits since both compartments stopped cooling at the same time. any other culprits if the board is not the problem??"
here's why i think it may not be a compressor problem: even though the compressor is not running, i measure 120VAC at the input and, when the connector is removed, the start windings are at 4.2 Ohm, the run windings are at 3.3 Ohms, there is 8.3 ohms between run and start and there is no short between the pins and the compressor body.
doesn't it make sense that the defrost control board could be forcing a continuous defrost? if that is the case, it would turn the compressor off but keep the fans running, right? is there a way to jumper the board to force the compressor on? if so, then i can determine if my compressor is good or not.
does anyone out there know enough about the defrost control board to help me with this?

Ok RPP, all 3 of us techs here have told you the problem.
Lock-up means your compressor internally won’t start the internal
compressor piston, thus the compressor can’t start.
Nothing will make the compressor run when its locked-up
