A few questions:
- Is servicemanuals.net any good? They have a manual for this fridge, but their "sample" has nothing within it which would indicate the quality of the full document.
- Is there a test mode for Samsung fridges, akin to what I've seen on an LG model in this video?
- What might cause all the fans in the freezer/fridge compartments to not blow?
- How can I test them? Either the sensors or the fans themselves.
My compressors runs, judging by the noise. The fan between the compressor and the coils is spinning, blowing fairly hard.
There is no airflow from any of the vents in the fridge/freezer. We first noticed the problem in the freezer, and as of right now the freezer is 56 degrees and the fridge is holding steady at 38 despite being in Power Cool mode.
I'm wondering if there is some single point of failure that would cause all 4 fans to not run. The easiest thing would be to replace the motherboard, but how can I verify that this is the real problem? I've found on the circuit diagram a connector with labels for various fans. I disconnected it and tested the voltage between the ground pin and each of the others, both on the plug and the receptacle, and got noting for any of the pairs. I was pretty sure that when I pulled the connector some of the humming stopped, like I'd perhaps killed a single functional fan. I just tried that again, and it's definitely stopping something (not the compressor) when I unplug it. It sounds like it's coming from the lower fridge compartment, and indeed there are pop cans in there that are still quite cold. Seems strange that 3 out of 4 would go bad together.
