What is a relay in a refrigerator?
A relay in a refrigerator is an electrical component that acts as a switch to control the compressor’s operation. When the temperature inside the refrigerator rises above a certain level, the relay sends a signal to turn on the compressor, allowing the refrigerator to cool down. Conversely, when the desired temperature is achieved, the relay turns off the compressor.
This component is crucial for the efficient functioning of the refrigerator, as it ensures that the cooling cycle operates as needed. If the relay fails, it may result in the compressor not starting or stopping at inappropriate times, leading to temperature fluctuations and potential spoilage of food.
