Johnald for Model Number RFG298AARS I recently had a power outage and the fridge would not cool. I am getting 5 flashes on the LED for the Power Control Board. I followed the procedure in this link below. https://www.appliancepartspros.com/answers-for-samsung-assy-pcb-sub-da41-00614f-ap4981905-question-259712.html Everything checks out OK, except I am reading 2.0 volts instead of 2.5 volts for pin 4 of CN75. Is the Main Board or the Power Control Board the issue? Thanks. From the original question: ******************************* At connection CN75, you will want to place the red probe of a multimeter onto pin 4 and the black probe onto pin 2 of CN32. If there is not 2.5VDC, then the main control [DA41-00620B] has failed. If the DC voltage tests at 2.5V then you will want to check the incoming voltage at the inverter (leave the black probe in place at CN32 pin 2) which would be the orange wire, and it should read the same. If it does not, then there is a wiring issue. If the voltage reads the same, then you will want to test the brown wire for 5VDC. If this fails, then there is a main control failure. If it checks good, then you will want to test the red and gray wire at the inverter for 120VAC. If this all checks good, then the failure would likely be in the inverter control [DA41-00614F].
Answer Johnald, Based on the information provided the 5 flashes are for an "UNDER VOLTAGE" issue and you would need to check the "INPUT VOLTAGE". Read More... Answered by AppliancePartsPros.com | Friday, September 10, 2021
