I need a service manual for a Samsung Quattro RM257ABRS to trouble shoot it and hopefully pull some error codes. My fridge is almost 6 years old.
I came from a 5-day vacation and found my fridge not cooling at all, both freezer/fridge. The compressor is not running and hasn’t ran since. i noticed water on my tile floor was already dry, so must of happened at least 1-2 days prior. i checked compressor overload and still good. I’m getting 115v at each of the compressor terminals. I checked resistance of compressed and get 10.9, 10.0 and 10.9 ohms between the terminals. I think thats ok assuming its a 3-phase compressor. I know on other compressors, combined resistance of two of the terminals are supposed to add up to the third. I also did the ground test to each terminal and all seems ok, no indication that the compressor is bad, other than it is not starting.
I’ve replaced the power and inverter pc boards, but still no compressor. I also replaced the defrost thermostat on the freezer side and still no luck. i checked resistance at the freezer defrost heater and read about 60 ohms and about 160 ohms on the fridge side, I don’t know if thats good or not.
At this point i feel i’m just shot-gunning parts in and hoping for the best. I"m assuming its a defrost issue and find Samsung fridges with defrost heater issues on a large number of their models . I found the heaters for not that much online, so i’m continuing the shotgun approach. Temp sensors are only about $6, so I might as well swap out the ones i can get too and hope an open circuit is what is not allowing the compressor to kick on.
Any help/advice is appreciated. Thx.
