Have you found a crack on the inside back wall of the refrigerator? This is a common problem that can occur in both new and old models. Most often, cracks appear due to temperature changes, mechanical damage or manufacturing defects. But don’t rush to panic: in most cases, the situation can be corrected without expensive repairs.
In this article we will look at why the back wall of the refrigerator cracks, what safety measures need to be followed, and what to do depending on the type of damage. You will learn when you can do it yourself and when it is better to call a specialist. We will also take a detailed look at what materials and tools will be needed for repairs, and how to prevent the recurrence of cracks.
Why the back wall of the refrigerator cracks: 7 main reasons
The back wall of the refrigerator is not just a decorative element. It performs important functions: it protects internal parts from moisture, maintains thermal insulation and prevents the formation of condensation. Cracks can appear on it for various reasons, and not all of them are associated with faulty equipment.
Here are the most common reasons:
- 🔥 Temperature changes — if the refrigerator is often opened or it is standing next to a heat source (stove, radiator), the plastic may deform and crack.
- ❄️ Improper defrosting — using sharp objects to remove ice often leads to mechanical damage.
- 🏗️ Factory defect —thin or low-quality plastic can crack even during normal use.
- 💧 High humidity —if the door seal worn out, condensation accumulates inside the refrigerator, which over time destroys the plastic.
- ⚡ Compressor vibrations - in older models, vibration can be transmitted to the back wall, causing microcracks.
- 🧊 Water freezing in the drainage hole - if the drainage is clogged, ice can put pressure on the wall from the inside.
- 🔧 Improper installation —if the refrigerator is not level, this creates additional stress on the back panel.
In some cases, a crack may be the result of a more serious problem, for example, refrigerant leaks or thermostat malfunctions. If, in addition to a crack, you notice that the refrigerator is not cooling well, making unusual sounds, or too much frost is forming on the walls, this is a reason for diagnosis.
Is it dangerous: when a crack threatens the operation of the refrigerator
Not every crack on the back wall of the refrigerator requires urgent repair. However, there are signs that indicate that the problem is more serious than it seems:
- 🚨 Crack passes through the drainage hole - this can lead to stagnation of water and the appearance of mold.
- 🔌 Visible exposed wires or contacts behind the wall - high risk of short circuit.
- ❄️ Around the crack ice or frost - the thermal insulation may be damaged.
- 💨 From a crack cold air is blowing is a sign of depressurization of the chamber.
If the crack is small (up to 5 cm) and is not accompanied by other symptoms, you can repair it yourself. But if you notice at least one of the listed signs, it is better not to risk it and call a specialist.
⚠️ Attention: If a crack appeared after strong impact (for example, when moving), there is a risk of damage freon circuit. In this case, the refrigerator cannot be turned on - you urgently need to disconnect it from the network and call a specialist.
| Crack type | Danger | Can I repair it myself? |
|---|---|---|
| Small (up to 2 cm), without additional symptoms | Low | Yes |
| Medium (2-5 cm), with slight frost around | Medium | Yes, but you need to monitor the condition |
| Large (more than 5 cm), with visible wires | High | No, a master is required |
| Crack with liquid leaking or a strange smell | Critical | No, turn off the refrigerator immediately! |
What to do first: 5 steps when a crack is detected
If you notice a crack on the back wall refrigerator, don't panic. Follow this algorithm:
- Unplug the refrigerator —this will prevent the risk of a short circuit if the crack touches electrical components.
- Empty the chamber of food —move them to a cool place (for example, in a cooler bag or on the balcony if it’s winter outside).
- Inspect the crack in good lighting —use a flashlight to assess its depth and the presence of additional damage.
- Check for a refrigerant leak —if you smell a chemical smell or there are oily stains on the floor under the refrigerator, immediately ventilate the room and do not turn it on equipment.
- Take a photo of the damage - this will help when contacting a service center or for comparison after repair.
If the crack is small and is not accompanied by other problems, you can proceed with the repair yourself. Otherwise, it is better to call a specialist.

How to repair a crack with your own hands: step-by-step instructions
If the crack is shallow and does not affect critical elements, you can repair it yourself. For this you will need:
- 🧴 Glue for plastic (for example, Loctite Plastics or Cosmofen).
- 🧊 Epoxy resin (for large cracks).
- 📄 Fiberglass or plastic patch (if it is necessary to strengthen the repair area).
- 🧼 Degreaser (alcohol, acetone).
- 🔧 Spatula or plastic spatula for applying glue.
Step-by-step process:
- Cleaning the surface - remove dirt and grease with a damp cloth, then degrease the crack.
- Preparing the glue - if you are using epoxy resin, mix it with the hardener according instructions.
- Applying glue —carefully fill the crack with glue, trying not to go beyond its edges. For deep cracks, you can use a syringe.
- Installing the patch —if the crack is large, stick fiberglass or plastic on top patch, then cover with glue again.
- Drying — leave the refrigerator turned off for 12-24 hours (depending on the type of glue).
- Grinding —after drying, carefully sand the repair area fine sandpaper.
To mask the repaired area, you can use acrylic paint the color of the refrigerator or a special sticker.
When to call a professional: 4 signs that homemade repairs will not help
Not all damage to the back wall of the refrigerator can be repaired at home. There are situations when you can’t do without professional help:
- ⚡ Electrical components are damaged - if a crack has exposed wires or contacts, independent repair is dangerous.
- ❄️ Thermal insulation is broken - if ice constantly forms around the crack or the refrigerator does not freeze well, the problem may be deeper than it seems.
- 💨 Refrigerant leak —if you smell a chemical smell or the refrigerator has stopped cooling, you need professional diagnostics.
- 🔧 Crack on warranty refrigerator —self-repair may void your warranty.
The cost of repairs at the service center depends on the model of the refrigerator and the complexity of the work. On average, replacing the rear panel costs up to 3,000–8,000 rubles, and restoring thermal insulation costs up to 15,000 rubles. However, if the problem is related to a freon leak, repairs may be more expensive.
⚠️ Attention: If your refrigerator is under warranty, Do not try to repair it yourself - this will automatically void the manufacturer's warranty.. Contact an authorized service center.
How to prevent cracks from appearing: 6 simple rules
The best repair is prevention. To keep the back of your refrigerator intact for as long as possible, follow these tips:
- 🧊 Defrost the refrigerator correctly —do not use knives or forks to remove ice. It’s better to wait until it thaws on its own, or use a plastic scraper.
- 🌡️ Control the temperature —do not place the refrigerator next to a stove, radiator or window that receives direct sunlight.
- 🚪 Keep an eye on the door seal —if it is worn out, moisture will accumulate inside the refrigerator, which will accelerate the destruction of the plastic.
- 🧼 Wash the refrigerator regularly —dirt and grease can corrode the plastic, making it more fragile.
- 📦 Do not overload the shelves —heavy products (for example, cans of preserves) can deform the back wall.
- 🔧 Check the drainage hole —if it is clogged, water will accumulate and freeze, creating pressure on the plastic.
It is also worth paying attention to vibration level the refrigerator. If it rattles a lot during operation, check whether it is level and, if necessary, adjust the legs.
What to do if a crack appears on a new refrigerator?
If your refrigerator is under warranty (usually 1-2 years), contact the brand's service center. According to the Law “On the Protection of Consumer Rights,” you have the right to free repair or replacement of equipment if a manufacturing defect is detected. The main thing is not to try to repair the refrigerator yourself, otherwise the warranty will expire. Save the receipt and photographs of the defect - this will speed up the process of considering your application.
Common mistakes during repairs: what not to do
Many try to repair a crack on the back wall of the refrigerator with improvised means, but some methods can only aggravate the problem. Here's what you absolutely cannot do:
- 🔥 Use superglue or PVA —they are not intended for plastic and can crack over time.
- 🔨 Drill holes to “tie” the crack —this can damage the internal parts of the refrigerator.
- 🧴 Apply adhesive tape or electrical tape —they are not airtight and can fall off, blocking the drainage.
- 💨 Ignore the smell of refrigerant —if a chemical smell is felt, the refrigerator must be turned off urgently.
- 🔌 Turn on the refrigerator with a wet back wall - this can lead to a short circuit.
Also, don’t try paint over the crack without preliminary repair - this will not solve the problem, but will only mask it for a while. If the crack is deep, the paint will quickly peel off.
FAQ: Answers to frequently asked questions
Can I use the refrigerator if the crack is small?
Yes, but with caution. If the crack does not affect electrical components and does not lead to cold leakage, the refrigerator can be used. However, it is better to repair it as soon as possible to avoid further destruction of the plastic.
