Now, I share all the tips I’ve learned on this blog. If you ever hear your refrigerator begin making a clicking sound, you’ll know what to check first. However, another benefit of building a unit like this is that you can fill the cupboards with stuff, which just adds more mass to the structure. Finally, avoid placing too much or too little food into the fridge. The inner workings of compressors can be a challenge to navigate, so if your compressor appears to be the problem, it’s best to call a professional. Clean down the inside of the fridge and remove all shelves (and food). This stems from the compressor trying to re-start itself. Some manufacturers of sound deadening mats, such as Hushmat or Dynamat (Amazon links), make products for use in the home. As I’ve covered above, a fridge needs air to flow around its coils in order to cool them. It's time to call a tech for a compressor job, or to think about getting a new fridge. You will hear the overload in the "3-in-1" cycling (CLICK-BUZZZZ-CLICK.) However, this also means that they can’t be covered up. Increased noise can be a sign that parts are worn out or broken, meaning these (or the whole fridge) might need to be replaced. A noisy sound coming from the back of the fridge is probably the condenser fan or the compressor. Regularly Clean the Compressor and the Fans. He graduated from the University of Nebraska at Omaha where he obtained a Finance and Banking degree. Afterward, plug it back in and switch it on. Also, as the compressor overheats due to dirty condenser coils, it turns on and off, causing clicking sounds to come from the back of the fridge every 2-3 minutes. After all, this noise might be an indication of something being loose or broken. Now that we’ve gone through some of the general noises a fridge makes, along with their sources, it should be much easier to explain how to make them quieter. Another worthwhile option for making the condenser quieter is to try cleaning it, as it could just be old or dirty. Here is a short but helpful video for cleaning compressor coils. You’re not the first person to dislike noisy fridges, and it’s likely some people will talk about this in their review. Doing so could cause the fridge to overheat, which will cause the compressor to overwork and break down. If you think the start relay may be the source of refrigerator clicking, it’s easy to see for yourself without calling a professional just yet. One issue the refrigerator’s compressor may be having is a bad start relay. If you take good care of your refrigerator, you’ll keep it in better working condition, avoid unnecessary repair service calls, and increase its overall lifespan.

This makes it great at absorbing sound waves and vibrations. 6. Otherwise, you can use a vacuum and a dry, clean cloth. If neither runs and the compressor is hot, unplug the fridge and point a fan or a hair dryer set to “no heat” at the compressor. If not, that’s great news – you fixed it with a simple cleaning of the condenser coil! As a formerly licensed real estate agent and property manager of 500 single-family homes, Andrew knows real estate. Stable and even are two different things, and your refrigerator might be stable but wonky if it’s on a wonky floor. Then, follow behind with a dry, clean cloth to remove any remaining dirt. This stems from the compressor trying to re-start itself. If dirty condenser coils are the culprit, the clicking sound you hear is actually the sound of the refrigerator’s compressor turning on over and over. If you were able to stop the refrigerator clicking sound by cleaning the condenser coils, replacing the start relay, or reshaping the condenser fan, keep the solution that worked in mind. This is commonly a case of the fan becoming blocked from a build up of dust, reducing air flow, resulting in a knocking or clicking noise. Similarly, over time, as a result of vibrations and general use, these legs might come loose or move around. If the clicking sound is accompanied by a loss of cooling (and a puddle of water or spoiled food), keep reading to determine what the issue stems from. A noisy fridge produces a lot of sounds, and it might be tricky to spot where each sound is coming from. If you ever hear your refrigerator begin making a clicking sound, you’ll know what to check first. A bad compressor may be accompanied with little to no cooling taking place in your refrigerator. You can now use the condenser brush to get in between the bends of the coil and thoroughly clean it off. fits various makes and models. Does it sound like a grinding, scraping, or knocking, as if something is being hit by a fan’s blades? However, it is possible that the sound is caused by compressor overload. Do bear in mind the space that’ll take up, as a quarter-inch thick material will take up over an inch of space here. After it is compressed, the coolant gas moves through condenser coils to help the heat dissipate from the gas so it can be compressed again. If you do hear a humming noise, but the food in your fridge is warm, your compressor may be functioning improperly (or it may be a different issue causing the problem altogether). 5. Within the refrigerator itself, you have many reasons for the sudden increase in the noise such as : Compressor: Due to different mechanisms of liquid flowing through, you might hear a noise like a whirr, drip, or hiss. With so many different models and types of refrigerators and no shortage of information available online, you may end up spending lots of money on unneeded parts, damage essential parts of your refrigerator, and waste time troubleshooting. Shake n’ Tell for a Bad Compressor The first step to making a loud fridge quiet is identifying the source of the sound. Refrigerator clicking is caused by one of a few reasons. If you hear your refrigerator clicking, you might worry the unit is going out and will need to be replaced. The only issue with this is that condensers can be an expensive part to buy, and may even make the whole exercise unviable. If it moves, then you need to adjust the legs accordingly. Replace the lower back panel and plug the refrigerator in again to see if it worked. You may even find that this is actually the most helpful thing you could’ve done. If you notice that your refrigerator's compressor clicks on and off or … Again, it might be worth getting a professional out to do this. I was wiggling it last night to try and track down the noise, and it's the internals of the deal hitting the outside housing. Your refrigerator’s compressor has a simple job: Compress the gas that cools your refrigerator. Doing this basically means the sound waves are trapped in a smaller space and have less chance of bouncing around the room. I’m not going to go into how you should build a shelving unit, because that’ll mostly depend on the space you have available. The dirt and grime essentially create a physical barrier that stops the coils from getting rid of the excess heat from the compressed gas. In the rest of this article, I look at ways to combat the majority of noises a fridge makes, but I’ll be concentrating on the compressor. It’s a good idea to run through these simple troubleshooting methods to see if you can quickly and fix the problem when your refrigerator is making a clicking sound. Condenser fans can have a few issues. The clicking sound may come from your fridge’s condenser coils, the compressor, start relay, or the condenser fan. This fridge has two separate evap coils one … The rear of the refrigerator has the compression coils, through which the fluids pass to release excess heat energy. Try to turn the condenser fan by hand. I started soundproofing when I built my home theater room. If you’re not too sure whether the noises your refrigerator is making are normal, then I’d obviously recommend getting a professional to look at it. The mats are generally less than an inch thick but do a great job. Soundproofing behind the fridge will take care of part of it. Hopefully, you’ve noticed a significant reduction in airborne noise! However, the most likely source of noise is going to be the compressor. Plug the refrigerator back in and listen to see if you hear more refrigerator clicking.

Rather than helping the issue, that’ll just make it worse! So, even if you set them properly when you first installed the fridge, it’d be worth checking them again. If you’ve got a more modern energy-efficient refrigerator, its compressor is designed to work long and low, so don’t be surprised if it stays on for quite a while. The fan will stop when the refrigerator reaches the set temperature. You may want to stop by a store that sells plumbing items and pick up a special condenser brush designed to effectively clean condenser coils. In this article, I look at some creative ways to make your refrigerator quieter, but also some advice for troubleshooting this problem. This is due to the compressor attempting to turn on, failing, and trying again in a set interval. If the condenser fan isn’t turning, the clicking sound is likely due to the compressor overheating. The mats are made of something called butyl rubber, which is a very dense material with little elasticity. This will save them time and help them find the real culprit for the refrigerator clicking faster. Step 6 - Check the Defrost Setting The fridge’s age. Put the Fridge on an Acoustic Mat. Either way, if you feel confident enough then it’s definitely worth having a poke around inside the fridge to see if you can solve any of the problems with a bit of light cleaning.

They will be able to diagnose and repair any issue happening to your refrigerator. 4. Remove the lower back panel and look inside for a small fan near the compressor. If you’re looking to upgrade then you’ll probably be looking for a brand new one, but this advice applies to secondhand ones too. Similarly, adding a sheet of mass loaded vinyl to the wall behind your fridge will stop any impact noises that might occur. Some compact fridges, and some normal sized ones too, don’t actually have fans as part of their cooling mechanism. Read on to learn more. In this case, you will need a new condenser fan. Mass loaded vinyl is limp mass, and so doesn’t pass on vibrations caused by sound waves. When the refrigerator compressor starts up or shuts off, it may make sounds similar to an ignition from a car engine. Hopefully, this will help you to relax a bit more at home!
