So I have read the rapid resolution and watched the Samurai's video, plus read Durhams write up on Samsung refrigerators. All very helpful, but I'm still having some trouble with the refrigerator I'm looking at. I've requested the detailed service manual. In the mean time. The original complaint was a warm fresh food section. There was ice on the floor of the freezer, I've since learned what I need to do to fix the frozen defrost drain issue and fan. Today I went back to try and check some things, I verified the door switch on the freezer door is working and the magnetic switch for both doors is working. I checked voltages to the fan motors and between Grey and Blue (GND- CFan) I got 8.16VDC, Grey and Yellow(GND - Ffan) I got 8.54 VDC, and between Grey and Orange (GND- Rfam) I got 0 VDC. The lights that are on in the picture of the control were not steady but blinking and I was unable to get the control to do anything. Without a manual I don't know if this is a failure code or what else I need to look at.
At this point I think I'm dealing with two different issues, one being the defrost drain freezing and the other being a faulting control board not sending power to the fresh food fan. Any other input for this model would be appreciated. It's in a second home and not used all the time. The customer had unplugged the unit a couple times for several hours before calling me. Thanks in advance.
