Larry A New Orleans , LA December 29, 2019 Appliance: Samsung Electric Range NE594R0ABBB/AA-01 Samsung Range Ne594r0abbb/Aa-01: Missing display numbers and some non working keypad buttons. How to replace Assy Pcb Main;Led,Oas-Ag. Received control panel, installed, and nothing! I reviewed the picture I took of the wiring and confirmed all connections were correct. Still no power on the new control panel. I call customer service and spoke with a tech regarding this issue. I was sent another control panel with the thinking the first was defective. I also ordered a new membrane due to some of the buttons not working. A few days later, I received both items, installed, closed up the back of the range, and now ready for the big test. Plugged in the power cord, and YES! All is good! All the buttons work. Totally satisfied with your customer service department. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
