Thomas S Tampa , FL June 05, 2023 Appliance: Samsung Range Electric NE59J7850WS/AA No convection heat in top oven. The spade connector on the board overheated and burned wire and the spade connector on the board. Replaced oven control board and wiring harness. It took a bit to find the right replacement parts, but both the Main PCB and wire harness were perfect matches! Many of the spade connectors have locks that require a small flat screwdriver to be inserted from the wire end to release the latch, then pull the connector and screwdriver together. Once I figured that out the rest were easy. I may have been able to replace just the single spade connector that was burnt but didn't know how far back I would need to cut the wire back to get to undamaged wire, and it was a shortish lead. Plus, the burnt connector was a dual spade connector. Not sure if the original connector was loose which caused the overheating, but new board and harness and it's like factory new. Read More...
