Hi All, Samsung damper is apparently closed, freezer fine but fridge around 50'sF. I took the damper out, opened up, no lock-ups found, removed motor so gears no engaged and bench tested the actual small motor by 12V DC, it was jerking a bit when DC applied but not spinning, it was spinning freely only by hand when power off and when power on, it was holding but I could spin it with more force and could feel the magnetic field acting in steps, no mechanic obstruction. I couldn't cross and find these little motors on the web but I feel it may be powered by different voltage then DC. Perhaps some pulse if not AC generated by the PC board but I am just guessing so if anyone ever played with this please let me know. I tend always go to detail since it is a hobby to me as well. Didn't check thermistors voltage drop yet but tonight I'll do it after smacking all back together. Perhaps the circuit on the PC board has an issue not making the proper current/voltage type so it can not spin and it maybe originally making by factory less than 12 Volts. All 3 thermistors checked OK at ambient room temp. and in Icy water and all are type sealed. Other fridge Kenmore similar to this one some time ago have shown good thermistors after test but under the load the freezer-one failed apparently making fridge running non stop. I just replaced the thermistor and it runs good ever-since. Didn't check voltage drop at that time so who knows but apparently basic test using ice water is not enough in some cases especially where freezer goes to bellow 0F. Thanks for attention.......................
