Samsung Compressor & Sealed System

This is a positive temperature coefficient (PTC) start relay that helps the refrigerator compressor start up by providing an initial boost of electrical current. It is mounted on the side of the compressor and is essential for proper cooling operation. Replace this relay if your refrigerator is not cooling, the compressor clicks on and off repeatedly without running, or you hear a buzzing sound coming from the back of the unit.

Refrigerator won't cool or freezer stopped working? A failed compressor prevents refrigerant circulation. Professional repair recommended due to complexity.
