how does a start relay work

A start relay is an electrical component used in refrigeration systems to help start the compressor. It works by temporarily increasing the electrical current to the compressor motor during startup, giving it the extra boost it needs to get up and running. The start relay is activated when the refrigerator's thermostat calls for cooling, and it quickly delivers the necessary current to the compressor. Once the compressor is running, the relay deactivates and allows the normal electrical current to power the motor. This process helps prevent damage to the compressor and extends its lifespan. By effectively controlling the electrical current during startup, a start relay plays a crucial role in the reliable operation of refrigeration systems. It is a simple yet essential component that ensures the smooth and efficient functioning of the compressor, ultimately contributing to the overall performance of the refrigerator.
