Ralph L Beavercreek , OH February 04, 2019 Appliance: Samsung Refrigerator RB215LASH/XAA-0000 Samsung Refrigerator Rb215lash/Xaa-0000 / : Our Samsung ice maker quit working. How to replace Refrigerator Main Control Board Assembly. I researched on YouTube what others with Samsung refrigerators did with similar problems. I was able to come to the conclusion that is was not likely the icemaker but the main board. I also diagnosed a noisy fan motor in the freezer compartment. And while I was at it I decided to replace the led readout board that had recently become dim after a power outage. All in all the three repairs took a little over three hours. Thanks to the upselling of Sally I also purchased a brush for cleaning the fins in the machine area of the refrigerator. I am very thankful for this job to be done and thankful for the assistance of Appliance Parts Pros. Our refrigerator works as good as new with the ice maker working once again. Thank you Ralph Lofthouse 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
