What is a refrigerator relay and what does it do?
A refrigerator relay is a crucial component that helps manage the compressor’s operation within the refrigeration system. It acts as a switch that controls the electric current flowing to the compressor, allowing it to turn on and off as needed based on the temperature settings. Proper functioning of the relay ensures that the refrigerator maintains the desired temperature while preventing the compressor from constantly running, which can lead to overheating and increased energy consumption.
When the temperature inside the fridge rises above the set point, the relay sends power to the compressor, activating it to cool down the interior. Conversely, when the desired temperature is reached, the relay disconnects the power, shutting off the compressor. A malfunctioning relay can result in continuous running of the compressor or failure to start, leading to temperature irregularities and spoilage of stored food.
How can I tell if my refrigerator relay is faulty?
Identifying a faulty relay can be done through a few common symptoms. One of the most evident signs is that the refrigerator is not cooling properly, which may indicate that the compressor is not receiving power.
