*** If you don't see your model number , please contact us to check it for you *** The PC Main Assembly is an OEM circuit board for Samsung top-loading washing machines. As the master control module, it handles input/output communication for all washing operations. Causes of failure usually involve moisture exposure over many cycles, which can lead to circuit erosion. Continuous vibration stresses solder joints and normal electrical overload risks damage.
