Whirlpool refrigerator is making a clicking sound

Modern refrigeration technology runs almost silently. Any additional sounds that the refrigerator makes in excess of the intended quiet hum - knocking, clicking, crackling - make the owner alert. But the unusual "clicking" sound of the unit does not necessarily indicate a malfunction. Naturally, the first thing to check if you hear unusual sounds is whether the refrigerator freezes at all? If everything is visually in order, the temperature reaches the set value and there is nothing special, except for clicks in the operation of the refrigerator, there may be several reasons for this sound. If a clicking sound is heard while the compressor is resting, the sound appears most likely due to material deformation during cooling and heating. Both plastic parts and tubes of the evaporator can crackle. There is nothing wrong with such noises - the design of the refrigerator allows some expansion and contraction of materials, and this will not lead to breakdowns. If you hear clicks when turning the refrigerator on or off, this is most likely the sound of the thermostat. Some models of temperature sensors are more sonorous and can be heard quite well. This is not considered a breakdown. However, if this is exactly your case, the refrigerator should click from the first hours of work in your house not more. If you hear clicking sounds when the refrigerator is running, important components might be defective. If your fridge stopped working and you hear a click every two to five minutes, there might be a problem with the start relay. The start relay is a device that starts up the compressor in order to compress and cool gas and liquid in the appliance. There might be a problem with your fridge, and it’s time to get to the root of it. Disconnect power from the refrigerator and remove the start relay from its socket on the side of the compressor. Give the relay a shake. If there is a rattle, your start relay is faulty and should be replaced. In some cases, you may need to test your relay using a multimeter to determine whether it has continuity. If you suspect your refrigerator’s start relay is bad, it’s easy to replace. Unplug the refrigerator and unplug the start relay. Plug the new one in, and it should work correctly. If the problem remains, you will have to run diagnostics using professional assistance.
