Skye for Model Number Samsung Refrigerator RS265TDBP/XAA-01 Coils on Fridge side build up with ice. Is this a temp sensor failure? The fan has been replaced and nothing changed. Thanks!
Answer Skye, this can be caused by a defrost sensor DA32-00029Q, defrost fuse DA47-00301B, defrost heater DA47-00322J, or a main control DA41-00670C failure. The defrost sensor would need to be tested from the main control while a thermometer is directly next to the sensor. Using the wires at the connection CN40, the purple wire at pin 11 and the gray wire at pin 4 would be tested for resistance. The sensor will measure 11,741O at 37°F, 13,290O at 32°F, 15,076O at 26°F, 17142O at 21°F, and 20,418O at 14°F. The defrost fuse should measure as having continuity and if it does not, then it has failed. The defrost heater should measure about 102O when tested for resistance. If these parts test good, the failure would most likely be in the main control. Read More... Answered by AppliancePartsPros.com | Thursday, October 1, 2020
