Cassandra O Los Angeles , CA February 09, 2017 Appliance: Model SAMSUNG REFRIGERATOR The motherboard burn and inverter burn my samsung refrigerator was not cooling at all I called the repairman and he diagnosed my refrigerator he tried to charge me $500 but I got the part from you guys and only spent $340. All we had to do was unplug the refrigerator and I'm plugged all the little switches from the motherboard in the inverter and easily came out and we just attached all the switches to the motherboard in the inverter. It was very easy it only took my husband like 15 minutes. At first the refrigerator would not turn on so he rechecked all the switches and realize that one of them was loose. When did click back the refrigerator turned on and now it's working better than ever. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
