DA35-00043U - Samsung Refrigerator Start Relay

This Samsung Refrigerator Start Relay (DA35-00043U) is a genuine part designed for use specifically in Samsung refrigerators. It plays a crucial role in initiating the compressor's operation at power-on, ensuring reliable compressor operation each time cooling is demanded. The start relay operates by activating an internal electromagnet that closes its relay contacts when the refrigerator thermostat calls for cooling. This action permits a large inrush of current to flow to the compressor, providing the necessary torque to overcome inertia and start the motor. Once the compressor is up to speed, the start relay deactivates, allowing the compressor to run on the main windings alone. Known also as a "Relay Protector O/L," this key component is essential for efficient compressor startup and operation. Symptoms indicating the start relay may be failing include the refrigerator failing to cool adequately, the compressor struggling to start, or not starting at all. If you notice these symptoms, a replacement might be necessary to ensure your refrigerator operates smoothly. Verify your refrigerator's model number for compatibility before purchasing to ensure this part will fit and function correctly in your appliance.
