Does the refrigerator crack when the door is closed: is it normal or a signal of a breakdown?

When closing the refrigerator door, do you suddenly hear a sharp crack, creaking or clicking sound? This sound can range from a subtle crackling sound to a loud crunching sound that can be heard even in the next room. Many users ignore such signals, attributing them to “model features” - but in 60% of cases they indicate a developing malfunction. In this article we will analyze all possible causes cod - from harmless (for example, loop distortion) to critical (breakage thermostat or compressor), and also give step-by-step instructions for diagnosis and repair.

It is important to understand: the nature of the sound is directly related to its source. For example, metal grinding most often speaks of friction of parts, and plastic crunch - wear of the seal or guides. We collected data from service centers and analysis of 150+ refrigerator models (Atlant, Samsung, Indesit, LG, Beko etc.) to identify patterns. It turned out that in 8 out of 10 cases the problem can be fixed on your own - without calling a technician. But there are exceptions, when a crack becomes the first sign of a serious breakdown.

Before starting repairs, answer three questions:

1. How long ago did the cracking appear? (Today / a week ago / several months)
2. Is it accompanied by other symptoms? (Poor cooling, flickering light bulbs, condensation on the walls)
3. Has the sound frequency changed over time? (It has become louder/quieter, appears more often)

1. Wear or contamination of the sealing rubber is reason No. 1

The seal (aka magnetic circuit) is a rubber band around the perimeter of the door that ensures tightness. Over time, it loses elasticity, becomes covered with microcracks or sticks due to fat and crumbs. When you close the door, the rubber band clings to the body of the refrigerator, creating a characteristic crack or click. According to service centers, this problem occurs in 45% of cases of complaints about extraneous sounds.

How to check the seal:

• 🔍 Visual inspection: bend the rubber band and shine it with a flashlight - if light gaps are visible, the tightness is broken.
• 📏 Test with a sheet of paper: close the door, first placing a sheet between the seal and the body. If it pulls out easily, the elastic band does not fit.
• 🧼 Checking for contamination: run your finger along the seal. Sticky residue or crumbs? The cause of the cracking has been found.

Solutions:

1. Cleaning. Wipe the rubber with soapy water (1 tablespoon of product per 1 liter of water), then lubricate with silicone grease or WD-40 (only for external sides!).
2. Alignment. If the seal is deformed, heat it with a hairdryer (temperature 50–60°C) and shape it with your hands.
3. Replacement. For models Samsung RB30J3 or Atlant MXM 170 original rubber bands cost 800–1500 ₽. More information about the selection is in the section on repairs.

2. Skewed or weakened door hinges

If the refrigerator creaks when opening/closing and the door “sags” down, the hinges are to blame. Over time, they become loose due to:

• 🏋️ Overloading of the shelves on the door (bottles, cans).
• 🔧 Loose fastenings (screws have become loose).
• 🚪 Incorrect installation (the refrigerator is on a slope).

Diagnostics:

1. Open the door and try to slightly lift it up. If it “walks”, the hinges are loose.
2. Look at the gap between the door and the body from above and below. If it is uneven (for example, 5 mm below, 1 mm above) - there is a skew.

3. Friction of plastic parts: guides and shelves

Modern refrigerators (LG DoorCooling+, Beko CNPE5252) often use plastic guides for drawers and shelves. Over time, they are used. are erased or deformed, and when closing the door, crunching or grindingoccurs. This is especially noticeable in models with a system No Frostwhere air circulates actively and creates additional load.

Typical “culprits” sound:

• 📦 Boxes for vegetables: if they are not pulled out completely, when closing the door they touch the body.
• 🧊 Ice tray: in models with a dispenser (Samsung RS6HA), the tray can cling to the mechanism.
• 🔄 Ventilation grilles: If they are moved, the air flow creates vibration and crackling.

How to fix:

1. Remove all removable elements (shelves, drawers) and check them for deformation. The plastic should not have nicks or cracks.
2. Lubricate the guides with silicone grease (do not use oils!).
3. If the part is broken, order a replacement from the manufacturer. For example, a drawer. for Atlant it costs 300–600 ₽, for Bosch — 800–1200 ₽.

What to do if the cracking noise comes from the freezer?

In 90% of cases, it is the fault No Frost system fanthat touches the ice with the blades. Try defrosting the refrigerator on. 10–12 hours. If the sound remains, the fan requires replacement (cost of the part: 1500–2500 ₽).

4. Problems with the compressor: when a cracking sound is serious

If the refrigerator not only cracks when closing, but and poor freezing, takes a long time to gain temperature or turns off 5-10 seconds after starting —the problem may be in the compressor. In this case, the crackling noise occurs due to:

• 🔧 Loose fastenings (the compressor vibrates and touches the housing).
• ⚡ Breakdown of the starting relay (characteristic click when turned on).
• ❄️ Motor jamming (loud grinding noise, after which the refrigerator turns off).

Compressor diagnostics:

1. Disconnect the refrigerator from the mains and wait 10 minutes.
2. Turn it on again. repeated clicks (every 5-10 seconds) - the relay is faulty.
3. Touch the compressor with your hand (it is located at the bottom at the back). Strong vibration means the fastenings are loose or the shock absorbers are worn out.

Solutions:

5. Deformation or breakage of internal parts

Sometimes cracking occurs due to hidden defectsthat are not visible during a superficial inspection. Here are the most common:

• 🧲 Magnetic valve (in models with Multi Air Flow) may stick and click when activated.
• 🔌 Thermostat (if it mechanical) makes a click when the compressor is turned on/off.
• 💡 Light bulb (in older models) may crack due to poor contact.
• ❄️ Evaporator (in systems No Frost) when frozen, creates a crackling sound when thawing.

How to identify the problem:

1. If the crackling coincides with turning on/off the refrigerator —check the thermostat and relay.
2. If the sound comes from top part - inspect the light bulb and the fan.
3. If a cracking sound appears 1-2 hours after closing - it's to blame evaporator (needs defrosting).

How to check the thermostat without tools?

Turn off the refrigerator, remove all food and leave the door open for 30 minutes. Then turn it on again. If the compressor does not start, the thermostat is faulty (replacement cost: 1000–2000 ₽).

6. External factors: floor, socket, vibration

Sometimes the reason for the crackling sound lies not in the refrigerator itself, but in its environment. Here's what's worth checking:

• 🔌 Socket: if the contacts are loose, you may hear a clicking sound when you turn on the compressor.
• 🏗️ Floor: an uneven surface (especially a wooden floor) increases vibration and creates extraneous sounds.
• 📦 Connecting items: If the refrigerator is close to a wall or furniture, a resonating crack may occur when the door is closed.

Solutions:

1. Check the socket: connect another appliance (for example, hair dryer). If it also “cracks” when turned on, replace the socket.
2. Use anti-vibration pads under the legs of the refrigerator (cost 200–400 ₽ in furniture fittings stores).
3. Leave a gap of 5–10 cm between the refrigerator and the wall/furniture.

7. When to contact a technician: 5 warning signs

Not all breakdowns can be fixed on your own. Call a specialist immediatelyif:

⚠️ Attention! If the refrigerator makes noises continuous loud grinding (as if “something scratches metal"), this may be compressor jamming. Further operation will lead to its complete failure and leakage of freon!

• ⚡ Refrigerator turns off after a few seconds after startup (clicks are heard).
• ❄️ The temperature in the chambers does not fall below +10°C, despite the maximum mode.
• 💧 An oily puddle appears on the back wall The refrigerator body (a freon leak).
• 🔥 Refrigerator body heats up more than usual (especially at the bottom).
• 🔊 A cracking sound is accompanied by burnt smell (electrical problems).

FAQ: Frequently asked questions about refrigerator cracking

Why does a new refrigerator crack when closing? Is this a defect?

In the first 1-2 weeks after purchase, a crash may be the norm - the parts are “grinding in” (especially plastic guides). But if the sound is loud or accompanied by other symptoms (poor cooling, condensation), contact the warranty store. In 20% of cases, the fault is defective seal or improper assembly of hinges.

The refrigerator only cracks at night. What's the matter?

At night, the compressor works harder (since the room temperature is usually lower and the thermostat turns on the cooling more often). If there is no sound during the day, but it appears at night, check:

1. Vibration level (perhaps resonating sounds intensify at night).
2. Fan operation (in models No Frost it can touch ice).
3. Network voltage (at night it is often lower, which leads to unstable operation of the compressor).

Is it possible to lubricate refrigerator hinges with WD-40?

❌ No! WD-40 is non-lubricantand a rust solvent. It will temporarily eliminate the squeak, but after 1-2 weeks the hinges will begin to creak even more, as it washes away the factory lubricant. Use WD-40 washes away the factory lubricant. Use silicone grease or Litol-24.

How often do you need to change the rubber seal?

The service life of the seal is 5–10 years (depending on the model and care). It needs to be changed if:

• Visible cracks or deformation.
• Loss of tightness (checked with a sheet of paper).
• The appearance of condensation on the walls of the refrigerator.

For models Samsung i LG original rubber bands last longer (7-12 years), for budget brands (Birusa, Posis) - 3-5 years.

The cracking appeared after the move. What to do?

Most likely, during transportation:

1. Loose compressor mounts (you need to tighten the bolts).
2. Warped door (adjust the hinges).
3. Damaged seal (check for creases).

Let the refrigerator stand 4–6 hours before turning on - this time is needed to stabilize the freon pressure.
