Sudden crunch under the weight of food or an accidental impact when loading vegetables - and you find a crack at the bottom of the container. Damaged refrigerator drawer becomes a serious problem: warm air penetrates inside through the cracks, which disrupts the temperature regime and causes the compressor to wear out. In addition, food begins to rot faster, and condensation accumulates at the bottom of the chamber, creating an ideal environment for bacteria.
Fortunately, in most cases, a complete replacement of the expensive original is not required. Modern polymers, such as ABS plastic or polystyrene, are highly recoverable with the right approach. You do not need to be a professional engineer to return the tray to functionality, but you will need accuracy and knowledge of the nuances of working with In this material we will analyze all restoration methods: from quick gluing to major repairs with structural strengthening.

In this material we will analyze all restoration methods: from quick gluing to major repairs with structural strengthening. You will learn which materials should absolutely not be used, how to properly prepare the surface, and when it is cheaper to buy a universal analogue than to look for the original.
Diagnostics of damage and assessment of the scale of work
First of all, you need to remove the damaged element from the camera and carefully inspect it in good lighting. Often microcracks are invisible at first glance, but they are the centers of further destruction of plastic under the influence of cold. Pay special attention to the places where the shelves are attached and the corner areas where the stress of the material is maximum.
If the box is simply cracked at the seam or has a small chip, it can be restored. However, if the plastic has become brittle, crumbles when touched, or has multiple deep breaks, repair may not be practical. In this case, it is better to consider the option of replacing it with universal analogue or searching for a used spare part.
⚠️ Attention: Before starting any work, be sure to disconnect the refrigerator from the power supply. Although the box itself is non-conductive, you will be working in close proximity to the camera's internal components where the sensors and wiring are located.
A ruler and marker will be required for an accurate assessment. Measure the length of the crack and the overall geometry of the product. This data will be needed if you decide to order a new tray or look for a donor for spare parts. Also check if the guides on which the box moves inside the chamber are damaged - sometimes the problem lies precisely there.
Preparation of tools and choice of glue
The success of the operation depends 80% on the correct choice adhesive composition. Regular superglue (cyanoacrylate) will not work: it becomes glassy and brittle at low temperatures, so the seam will come apart in a couple of days. You need specialized compounds that retain elasticity in the freezer.
The optimal choice is a two-component epoxy adhesive or special compounds for plastic marked “Flex” (flexible). Polyurethane-based adhesives have also proven themselves to be excellent. They create a seam that can withstand the expansion and contraction cycles of the plastic without losing its seal.
In addition to the glue, you will need:
- 🧼 Sandpaper (P120-P240 grit) to clean the edges.
- 💊 Rubbing alcohol or degreaser to prepare the surface.
- 🔧 Clips or clamps to hold parts in place while drying.
- 🛠️ Hairdryer (construction or household) for preheating the plastic.
- 🧵 Reinforcing mesh or fiberglass (to strengthen large cracks).
It is important to prepare the workplace. It should be well ventilated, as glue fumes can be toxic. Also take care to protect your hands - use gloves to avoid getting dirty and getting a chemical burn.
Technology for gluing cracks and chips
The restoration process begins with careful preparation. The edges of the crack must be cleaned with sandpaper, creating roughness for better adhesion. If the crack is through, it is recommended to make small notches across it to increase the contact area of the glue.
After cleaning, the surface is degreased with alcohol. Apply the glue in a thin layer, trying to avoid bubbles. If you are using a two-component composition, mix the components strictly according to the instructions, observing the proportions. For large cracks, use the “sandwich” method: a layer of glue, a reinforcing mesh, again a layer of glue.
☑️ Algorithm for gluing a box
Polymerization time can vary from 12 to 24 hours depending on room temperature and type of glue. Do not rush to put the box back into the refrigerator - the glue must gain full strength. It is not recommended to speed up the process by heating, as this can lead to deformation of thin plastic.
⚠️ Attention: Do not use the box immediately after gluing. Even if the glue “sets” in an hour, it will gain full strength only after a day. Early loading will lead to repeated destruction of the seam.
For aesthetics, after drying, the seam can be carefully sanded with fine-grained sandpaper. If the color of the patch differs from the color of the box, you can use food dyes or special markers for plastic that are safe for contact with products (after complete polymerization).
Repair of fixtures and shelves
Broken “ears” of fixtures or cracked partitions are a common problem. Here simple gluing is not enough, since these elements bear the main mechanical load. A more serious approach using reinforcement will be required.
If the fastener breaks off, it is best to drill small holes in the whole part and in the fragment itself, thread copper wire there or use plastic ties, and then fill the joint with epoxy resin. This will create a kind of “reinforcement” that will take the load on itself.
| Type of damage | Repair method | Required materials | Strength |
|---|---|---|---|
| Crack at the bottom | Gluing with reinforcement | Epoxy, fiberglass | High |
| Broken mounting ear | Drilling + wire + glue | Drill, copper wire, resin | Medium |
| Chipped corner | Plastic extension | Glue for plastic, file | Low |
| Crack on the wall | Gluing + clamp | Two-component adhesive | High |
In some cases, especially for glass shelves with plastic edging; repair of plastic is impossible without loss of tightness. If the plastic rim itself is cracked, you can try to replace it by choosing a similar one in size, or completely remove it, leaving the glass (if the design allows), but this will reduce the safety of operation.
Can a soldering iron be used for repairs?
Yes, the heat-soldering method is effective for thermoplastic plastics (polystyrene, ABS). The crack is sealed with molten plastic, but skill is required so as not to burn the bottom or deform the box.
Where to find spare parts and analogues
If repair is impossible, you will have to look for a replacement. Original boxes for models LG, Samsung, Bosch or Indesit are often unreasonably expensive and are supplied only through official service centers. The waiting period can be several months.
An alternative is universal boxes, which can be found on marketplaces or in spare parts stores. They are divided into several types according to the installation method: on wheels, on runners or hanging. The main thing when choosing is to take exact measurements of the old box: length, width, height and distance between the guides.
It is also worth considering the secondary market. Advertising sites often sell refrigerators “for spare parts” after a compressor has broken down, but with the insides intact. Purchasing such a donor may be more profitable than purchasing a new original container.
When ordering online, carefully study the product photo. Sometimes sellers post a photo of one box and send another. Check with the seller for compatibility with your model, citing the full device index, which is indicated on the nameplate inside the camera.
Prevention of repeated breakdowns
After a successful repair or replacement, it is important to follow the operating rules so that the problem does not recur. Plastic becomes brittle at low temperatures, so avoid sharp impacts and heavy objects (such as frozen packaged meat) falling to the bottom of the box.
Do not overload containers. Each drawer has a maximum load, exceeding which leads to deformation of the bottom and breakage of the guides. Distribute the weight of the products evenly, do not dump everything in one pile in the center.
Regularly check the cleanliness of the guides. If there are crumbs or ice stuck to them, the drawer will move stiffly, and when you open the door, you can accidentally yank it too hard, which will lead to breakage of the fasteners.
⚠️ Attention: Never try to force the drawer into place if it does not fit into the grooves. This is a sure sign of misalignment or the presence of an obstruction. Forced installation is guaranteed to lead to chips and cracks.
Following these simple rules will extend the life of the plastic elements of your refrigerator. Remember that caring for equipment is not only saving money on repairs, but also guaranteeing the safety of your products.
Frequently asked questions (FAQ)
What is the best way to glue plastic in the freezer?
Two-component epoxy adhesives with marked “for plastic” and “frost-resistant”. They retain elasticity at low temperatures and do not crack, unlike cyanoacrylate (super) glues.
Can the box be used immediately after gluing?
No, you must wait at least 24 hours for the glue to completely polymerize. Early use or cold storage can disrupt the curing process and damage the seam.
Where can I find the box number to order?
The part number is often stamped on the inside of the box itself, usually on the bottom or back wall. It can also be found in the instructions for the refrigerator or on spare parts websites for the refrigerator model.
Why does plastic turn yellow over time?
Yellowness appears due to exposure to ultraviolet radiation (if the refrigerator is located near a window) and oxidation of the plastic. It is difficult to bleach it, sometimes treatment with hydrogen peroxide helps, but this is a temporary solution.
