Samsung DC92-00133A Assy Pcb Main;Purple OEM Part

Replacing the PCB main board did the trick! It's a trivial "monkey swap". The wiring harnesses are even uniquely keyed (different shapes/sizes) making reconnect errors nearly impossible. Accessing the board was easy: the top of the washer comes off with the removal of a few screws on the top rear of the machine and the PCB board is also top rear mounted. The only downside is that both the original and replacement PCB boards are dipped in a thick coating of silicone/urethane making circuit board level repairs impossible. Monkey swap of the board is thus pretty much mandatory.

Each time it happened I would remove the front cover and test pump which would ohm out at 14-16 ohms and also would always run when tested. I left the top off and hooked meter into the purple wire at main circuit board that goes to pump and the other lead to ground. Ran a load and was able to see when acting up no power was coming from board. Installation was very easy diagnosis was much harder

Ordered new control board to replace burnt board. Opened up washer, disconnected old board and connected new board, then put washer back together.

Installed new PCB reassembled machine and powered up. All cycles work properly. The machine pumps out the water. It would be helpful to keep up with where the screws were removed from so they could be replaced in the proper holes.

Verified the door sensor wasn't the culprit by bypassing it, which confirmed it wasn't the issue. The main PCB was exactly the issue, and replacing it was a breeze. I will say that AppliancePartsPros have really come through! The local suppliers were saying 2-3 weeks out. Appliance parts Pros had it to my door the next day! Thank you guys. Great service. Quickest shipping ever.
