Samsung RSG257AARS - Cooling Issues
« on: August 03, 2014, 11:12:39 AM »
I'm into a Samsung Refrigerator RSG257AARS that seems not wanting to pull down colder than 21' Degrees in Freezer and 45' Degrees in Refrigerator. Tried running diagnostics but no errors turned up on the display. I've tried all diagnostics but can't seem to get anywhere. I pulled a Vacuum and put new dose of 134a - 7.5 oz. but don't getting cold enough. Should I try new (main and inverter) boards or am I jumping into a open pit? No ERROR DISPLAY for thermistor check when 1st starter either. Any advice would be helpful. Couldn't find Service Manual either just the FAST TRACK.

Ohm out all thermisters. The board will only give you an error if the thermister is shorted. The best way to test is to put each thermister in ice water for two minutes. I found two defrost thermisters way out if range low on a Samsung that wouldn't cool. Actual temp was 32 deg and I got a reading of -16 deg.

UPDATE ON THIS FRIDGE - FIXED ~~ !!


I changed out the MAIN Board and within a couple hours the Fridge pulled down to -4' Degrees in the Freezer and 34' Degrees in the Refrigerator Side


Everything is back to Spec !! Crazy how the Diagnostics did not pick up any Faults or Error Codes.....
