My samsung refrigerator had no power to the lights or controls Bill H. • Manchester, GA • October 20, 2014 Appliance: Samsung Refrigerator RF266AASH/XAA-0000 My Repair & Advice The unit had no power to any lights and the digital controls had no life. After a little Google research, I found the circuit and power board panel on the back of the refrigerator. With a Volt meter, I checked power at the input on the circuit board. It had 120V showing. On the output side to the circuit board there was nothing. I have ordered parts for some of my other appliances from APP before and they worked great. I ordered the power board and the circuit board. I felt like the power board was the culprit but wanted to be sure I had what was needed. Once I installed the power board and plugged the fridge into the wall, everything immediately came back to life and it began cooling. I'm returning the circuit board and have been happy with the service from APP. Was this review helpful to you?
