The refrigerator rumbles and makes noise: 7 reasons and what to do right now

You are standing in the kitchen, and suddenly the refrigerator starts rattling so loudas if a tractor had started inside it. The sound either increases or decreases, and sometimes turns into a vibration that makes the floor tremble. The first thought: “We urgently need to do something!” But before you grab the phone and call the technician, let's figure out why this happens and whether you can handle it yourself.

Modern refrigerators (Indesit, Samsung, Atlant, LG etc.) really should not operate absolutely silently - the compressor, fans and refrigerant circulation create background noise. However, if the sound becomes sharp, intermittent or accompanied by blows, this is a signal of a malfunction. In 80% of cases, the problem can be fixed without calling a specialist, saving up to 5,000 rubles on diagnostics.

In this article you will find:

• 🔍 Diagnostics based on the nature of noise — how to determine by sound what is broken.
• 🛠️ Step-by-step instructions to eliminate each cause (with photos and video links).
• ⚠️ Warningswhen self-repair is dangerous.
• 📊 Comparative table repair costs from craftsmen vs. independently.

1. The compressor knocks or “shoots” - what does this mean?

If the refrigerator makes sounds similar to hammer blows, with a 95% probability the problem is in the compressor. This sound is often compared to "shooting" or "rattling" from an engine. The reasons may be different: rhythmic metal knocking, similar to hammer blows, with a 95% probability the problem is in the compressor. This sound is often compared to "shooting" or "rattling" from an engine. The reasons may be different:

• 🔧 The compressor mounts are loose - during operation it vibrates and hits the body.
• ⚡ Problems with the start relay - if the knock is accompanied by clicks, the relay cannot start the engine.
• ❄️ System overload —the compressor is wearing out due to a freon leak or a clogged capillary tube.

The first thing to do is move the refrigerator away from the wall and inspect the compressor (black “drum” at the bottom). If it wobbles or shows signs of impacts on the body, the fastenings have become loose. In this case:

Check whether the compressor is touching the tubes or housing|Tighten the fastening bolts (a 10 or 12 wrench is required)|If the knocking is accompanied by clicks, turn off the refrigerator and check the start relay|Call a technician if, after tightening the fasteners, there is no sound disappeared-->

⚠️ Attention: If the compressor hot to the touch and knocking repeats every 5-10 seconds, this is a sign interturn short circuit in the winding. In this case, independent repair is impossible - the compressor needs to be replaced (cost from 8,000 rubles).

2. The refrigerator vibrates and “hums” - check the fan

A periodic hum clicking or grinding often comes from the fan that blows on the evaporator (in models with No Frost). If the fan blades touch ice or foreign objects, the sound becomes similar to “rattling.”

How to check:

1. Unplug the refrigerator.
2. Open the freezer compartment and remove the back panel (in most models it is secured with latches).
3. Inspect the fan for ice or frost. If there is ice, defrost the refrigerator at least 12 hours.
4. Check whether crumbs or food packaging have gotten inside.

💡 Useful advice: In refrigerators Samsung and LG with a system No Frost the fan may make noise due to faulty defrost sensor. If after defrosting the problem returns after 1-2 days, the sensor needs to be replaced (the cost of the part is ~1,500 rubles).

3. Shaking and knocking on the body is a problem with shock absorbers

If the refrigerator not only makes noise, but also knocks on the floor, the compressor shock absorbers are to blame. These rubber parts dampen vibration, but over time they harden or tear. This happens especially often in older models ( literally “jumps” and knocks on the floor, the compressor shock absorbers are to blame. These rubber parts dampen vibration, but over time they harden or tear. This happens especially often in older models (Stinol, Biryusa, Atlant over 10 years).

How to eliminate:

• 🔨 Replace the shock absorbers —they cost from 200 rubles apiece. Replacement will require a screwdriver and 15 minutes of time.
• 📏 Check the floor level —if the refrigerator is crooked, the vibration increases. Use a building level.
• 🧲 Place anti-vibration pads under the legs (sold in hardware stores).

⚠️ Attention: If the shock absorbers are torn and the compressor is broken hot and publishes uneven knocking, this may be a sign wear of the piston group. In this case, the repair will cost more than a new refrigerator (from 15,000 rubles).

4. Rattling when turned on - the start relay is faulty

If the refrigerator rumbles only when the start relay is turned onand then works normally, the problem is almost certainly in start relay. This small block is responsible for starting the compressor. If the relay malfunctions, the compressor “twitches”, trying to start, which is accompanied by loud clicks and knocks.

Signs of a faulty relay:

• 🔊 The knocking sound is repeated every 5-10 seconds, then the refrigerator goes quiet.
• 🕒 The compressor does not start the first time (multiple attempts are heard).
• ⚡ In some cases it works protection from overheatingand the refrigerator turns off.

The relay costs from 500 to 2,000 rubles, depending on the model. You can replace it yourself:

1. Disconnect the refrigerator from the network.
2. Remove the protective casing from the compressor (usually it is attached to one screw).
3. Disconnect the relay (it is connected to the compressor by wires) and install a new one.

📌 Important: Before purchasing a relay, check its brand - it is indicated on the body. For example, for refrigerators Atlant a relay is often used DANFOSS 103N0022, and for Indesit — RBM-10.

5. It makes noise and rattles after moving - the transport bolts

If the refrigerator starts to rattle immediately after delivery or moving, most likely they are to blame shipping bolts. They secure the compressor during transportation, and if they are not removed, the refrigerator will vibrate and knock during operation.

How to check:

• 🔧 Inspect the back wall refrigerator - the shipping bolts are usually located next to the compressor.
• 📋 The instructions for the refrigerator have a diagram of their location (section "Preparation for operation").
• ⚠️ If the bolts are not removed, this may lead to compressor breakdown!

💡 Helpful advice: In some models (Samsung RB30J3000WW, LG GA-B489YGQZ) transportation bolts are hidden under the decorative panel. If you are not sure, watch the video instructions for your model on YouTube.

6. Rattling and grinding is a problem with the capacitor

If the refrigerator makes noise metal grinding or rattlingand the sound comes from the back, check capacitor (the grill on the back wall). Over time, it can become dirty or bent, which leads to vibration and noise.

What to do:

• 🧹 Clean the condenser from dust vacuum cleaner or brush. This will improve heat transfer and reduce the load on the compressor.
• 🔨 Align the bent plates with pliers (carefully so as not to damage the tubes!).
• 📏 Check the distance to the wall - if the condenser touches the wall, it will vibrate.

⚠️ Attention: If the capacitor hot and traces of oil are visible on it, this is a sign refrigerant leaks. In this case, refilling with freon is required (cost from 3,500 rubles).

7. When to call a technician: 3 critical signs

Not all breakdowns can be fixed on your own. Immediately unplug the refrigerator and call a technician if:

💰 Cost comparison: Calling a technician to your home will cost 1,500–2,500 rubles (diagnostics only). If the problem is in the compressor or electronics, repairs can reach 50% of the cost of a new refrigerator. In such cases, it is more advisable to consider purchasing new equipment. Cost comparison: If the refrigerator is under warranty, this will void the warranty. data-i="206">etc.).

⚠️ Attention: If the refrigerator is under warranty, do not disassemble it yourself - this will void the warranty. Contact the brand's service center (Atlant, Bosch, Liebherr etc.).

How to find an official service center?

To avoid scammers, check service centers on the manufacturer's website. For example, for Samsung this is [samsung.com/ru/support](https://www.samsung.com/ru/support) (enter the refrigerator model in the search). For Indesit and Hotpoint-Ariston —[indesit.ru/support](https://www.indesit.ru/support). center authorized —this guarantees original spare parts.

FAQ: Frequently asked questions about a rattling refrigerator

❓ The refrigerator rattles only at night.

At night, the apartment is quieter, so the usual noise of a compressor or fan seems louder. However, if the sound appears suddenly, check:

• 🌡️ Room temperature - if it is cooler at night, the compressor works more intensely.
• 🔌 Network voltage - at night there may be surges that affect operation. relay.
• ❄️ Fan icing (in models No Frost) - defrost the refrigerator.

❓ Is it possible to use the refrigerator if it rumbles?

If the refrigerator cools normally and the rattling is not accompanied by other signs (overheating, shutdowns, errors on the display), you can use it. However:

• ⚠️ Monitor the temperature in the chambers - if it is. rises, turn off the refrigerator.
• 🕒 Do not delay diagnostics for too long - some breakdowns (for example, freon leakage) get worse over time.

❓ How much does it cost to replace a compressor in a refrigerator?

The cost depends on the model and type of compressor:

• 💰 Regular compressor (for example, for Atlant MHM 1705) - from 8,000 rubles (with work).
• 💰 Inverter compressor (for Samsung RB37J5240SA) - from 15,000 rubles.
• 💰 Compressor for premium models (Liebherr, Miele) - from 20,000 rubles.

💡 Tip: Before replacing the compressor ask the technician to check system integrity - if there is a freon leak, additional repairs will be required.

❓ Why does the new refrigerator rumble louder than the old one?

Modern refrigerators (No Frost, inverter compressors) may make a different noise than older models. Reasons:

• 🔄 Inverter compressor works non-stop, but at different speeds (it may seem like it is “rattling”).
• ❄️ System No Frost turns on fans that create additional noise.
• 📉 Energy efficient models (class A+++) may make more noise due to intensive work.

📌 Check noise level in the technical data sheet - if it does not exceed 40 dB, this normal.

❓ How to reduce the noise of a refrigerator without repair?

If the refrigerator is working, but makes too much noise, try:

• 🔧 Align the legs —use a level to eliminate vibration.
• 🧊 Check the door seal —if it is worn out, the compressor works harder.
• 📦 Do not place the refrigerator close together to the wall —leave a gap of 5–10 cm for ventilation.
• 🔌 Connect through a voltage stabilizer — surges in the network increase the load on the compressor.
