how does a start relay work

A start relay is an electrical component used in refrigeration systems to assist the compressor in starting up. It works by temporarily connecting the start winding of the compressor to the power supply, providing an extra boost of power to get the compressor running. The start relay contains a small electromagnet that is activated when the refrigerator's thermostat calls for cooling. This causes the contacts inside the relay to close, allowing the start winding to receive power and kick-start the compressor. Once the compressor is running, the start relay disengages and the normal operation of the compressor is maintained. This essential component helps prolong the life of the compressor and ensures efficient cooling of the refrigerator. It is compatible with various refrigeration systems and is easy to install. The start relay is a crucial part of a refrigeration system, providing the necessary power boost to get the compressor up and running smoothly.
