Seowon L Fullerton , CA March 22, 2020 Appliance: Model SAMSUNG RGF297AARS Inverter board. I requested the service. The man came and checked everything. Then, he said to me to need to replace the inverter board. So I ordered the part from appliancepartspros.com. My hubby replaced the part and it works really well. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
