The fan has the job of cooling the coils and compressor so they don’t overheat and reduce the cooling capacity of the refrigerator. And if you have pets that shed, you may have to clean them more often.įinally, fixing a faulty condenser fan helps reduce overheating on the coils and the compressor. They cause an overload of heat on the compressor, and the motor begins to click.Ĭlean the coils thoroughly and be sure to clean them according to the recommendations of the manufacturer. In addition to the above, the condenser coils can cause clicking noise from the compressor. Doing this allows the compressor to cool and restart normally. Unplug the refrigerator and wait a few minutes before plugging it back into power. Then, it shuts itself down in self-protection. Sometimes, the compressor draws more power than it needs and begins to click. Since the device supplies the power for the compressor to start and run, the compressor will have a hard time starting if the relay fails.Īnother reason for the clicking noise is a power overload. The compressor clicks off and on if the relay is faulty. If the relay shows no continuity, replace it. If it does not rattle, test it for continuity between its terminals. Typically, the relay should not rattle but if it does, replace the component. Detach the relay from the side of the compressor, and shake it while holding it. Refrigerator Compressor Clicking – How to FixĬheck the start relay if the compressor is clicking. If the timer is under the refrigerator and makes a rattling as the motor fails, you may think it is the compressor. Tighten the pan or find support for it to stop the rattling noise.įinally, check the defrost timer. A loose drain pan rattles whenever the refrigerator powers up or down. Like the condenser fan, its location makes it easy to assume the compressor is rattling when the noise is from the pan. And because it is close to the compressor, you may assume it is coming from the motor.Īlso, check the drain pan. Sometimes, the condenser fan makes the same noise when the blades are loose. However, be sure the rattling noise is coming from the compressor. But if it continues, the compressor may have internal damages and may need a replacement. For this, it may mean the compressor has some loose screws or bolts. When you should worry is when the noise is too loud and continuous. While the noise may seem like a problem, it is expected in some refrigerators. You may hear the rattling noise more clearly at night. Typically, a compressor makes a rattling noise when the refrigerator shuts down or turns on during normal operations. Refrigerator Compressor Rattling Noise – What to Do If the above fixes don’t apply to your refrigerator compressor, or they don’t fix the knocking noise, contact a qualified technician to check the compressor and determine whether or not it needs to be replaced. And when it moves, it hits other components and creates a knocking noise. When they become loose, they cause the compressor to move when the refrigerator moves. Tighten the bolts and screws holding the compressor in place. ![]() Lower the refrigerator and plug it back into the wall outlet. Then, tilt it a little to the back and turn the leveling feet until the front is slightly higher than the back. Unplug it from the wall outlet before starting. If the noise comes from the compressor, level the refrigerator. Clean the condenser fan and compressor, and make sure there is no ice around the evaporator fan. Sometimes, a knocking noise comes from the evaporator fan or even the condenser fan. ![]() While this noise is normal, it helps to leave the refrigerator without moving it around a lot, especially when you just installed it or powered it.īut there are other causes of a knocking noise from a refrigerator compressor, and to determine what is causing it, take the following steps: Step 1Įnsure the noise is coming from the compressor. The gas in the compressor can create a knocking noise when you move the refrigerator around.
