Steve for Model Number Samsung RF4287HARS/XAA-0001 My Samsung RF4287HARS/XAA-0001 regrigerator evaporator fan is not working, no voltage coming out from connector and ice build up on the coil. Is it main board problems or sensor? Steve
Answer Steve, to test for fan functionality, the main control will need to be accessed. At connection CN76 you will want to test for 7-12VDC from pin 4 with the red probe of a meter to pin 1 with the black probe. If there is 7-12VDC, either there is a wiring issue or the fan motor DA31-00146B would have failed. If there is not voltage, then the main control DA92-00233D has failed. If the fan does not operate, it can cause the refrigerator evaporator to have an ice build-up due to excessive compressor run time. Read More...
