The annoying sound that occurs every time you open or close the refrigerator compartment can piss off even the calmest person. This creaking not only disturbs the silence in the apartment, but also signals that the mechanism lacks care. If you ignore the problem, the friction of metal on metal or plastic will increase, which will lead to premature wear of the hinges and even misalignment of the door.
Fortunately, you can fix this defect yourself, without the help of a specialist. All you need is a basic set of tools and the right lubricant. In this article, we will look in detail at why noise occurs, what means are truly effective, and how to carry out the procedure in such a way as to forget about the problem for many years.
The first thing that needs to be done before starting any work is to determine the source of the sound. Often, equipment owners mistakenly believe that it is the hinge that is creaking, while the sound may come from the contact of the seal with the body or from the vibration of the internal shelves. Listen carefully: if the sound is metallic and harsh, then the problem is definitely in opening mechanism. If the sound is dull and stringy, perhaps the problem is in the rubber seal, which has dried out or become dirty.
Why creaking occurs: the main reasons
The mechanism for opening the refrigerator door is a simple but constantly working system. Over time, the factory lubricant applied by the manufacturer at the factory dries, hardens, or is washed away by detergents during cleaning. The absence of a lubricating layer leads to dry friction, which generates a characteristic unpleasant sound. This happens especially often in models with a system No Frostwhere doors are opened more often due to the need for quick access to products.
The second common reason is the ingress of moisture and dirt. The kitchen is a place where microparticles of fat and water are constantly floating in the air. When they settle on the open parts of the hinges, they form an abrasive mixture, which not only causes squeaking, but also accelerates corrosion. If you notice rust on the hinge rods, you need to act immediately, otherwise the metal will begin to crumble.
⚠️ Attention: If the creaking is accompanied by difficulty closing the door or it begins to open spontaneously, simple lubrication may not help. In this case, the hinge itself may be bent or the bushing may wear out, which will require replacement of the part.
It is also worth considering temperature changes. The refrigerator constantly vibrates when the compressor is running, and frequent opening of the door changes the temperature in the hinge area. This leads to expansion and burning of materials, which compromises the integrity of the lubricant layer. Plastic bushings in budget models of appliances are especially sensitive to this.
Choosing a lubricant: dos and don'ts
The issue of choosing a product is key, since the wrong product can ruin plastic elements or harm products. The market offers many options, but not all of them are suitable for use in food technology. The main requirement is chemical inertness and resistance to low temperatures, because part of the mechanism may be located in the cooling zone.
Edible silicone oil is considered one of the best solutions. It is odorless, non-toxic and retains its properties over a wide range of temperatures. Silicone prevents water from lingering on the metal, preventing corrosion, and does not destroy rubber seals. If you are looking for a universal product that can be found in any hardware store, pay attention to aerosols marked “for food production.”
It is strictly not recommended to use regular sunflower or olive oil. Even though it is edible, over time it oxidizes, thickens and turns into a sticky mass resembling glue. This will lead to the door jamming after a couple of months, and it will be extremely difficult to clean this substance. Also avoid solid oils and lithols with a strong odor, as their vapors can be absorbed into the food.
Can WD-40 be used?
WD-40 is an excellent rust solvent and moisture displacer, but a poor lubricant. It quickly evaporates and washes away the remaining factory lubricant. It can only be used for the initial cleaning of a rusty hinge, after which it is necessary to apply a full-fledged lubricant, otherwise the creaking will return in a week.
For modern models with decorative overlays, it is important to choose products that do not leave marks and do not contain aggressive solvents. Aggressive chemicals can corrode the paint on the case or make the plastic brittle. Always check the instructions on the can: it should indicate that the composition is safe for plastics and rubber.
Necessary tools and preparation
Before getting started, you need to prepare your workplace and tools. You don't need a complex professional kit, but having certain items will make the task easier and make the process safe. The main purpose of preparation is to provide access to the hinges and protect the floor and interior of the refrigerator from chemicals.
For work you will need:
- 🧴 Selected lubricant (spray or oil with a dispenser).
- 🔧 A set of screwdrivers (phillips and flat) or a screwdriver with the appropriate with bats.
- 🧽 Rags, paper towels or cotton swabs to remove dirt.
- 🧼 Mild detergent for initial cleaning.
- 🧤 Gloves to protect hands.
Always the first step there must be cleaning. It makes no sense to apply new lubricant on top of a layer of dust and old grease - this will only worsen the situation. Wipe the hinges thoroughly with a damp cloth, removing all visible dirt. If there is old rust, you can carefully use fine sandpaper, but be careful not to scratch the body.
An important point is to secure the door. If the refrigerator model allows you to remove the door, it is better to dismantle it completely. This will provide perfect access to all hidden hinge surfaces. If you do not plan to remove the door, ask someone in the household to hold it in the open position so that the mechanism is maximally straightened for processing.
☑️ Preparation for lubrication
Step-by-step instructions for lubrication of hinges
The lubrication process does not require engineering education, but requires accuracy and consistency. If you decide not to remove the door, then try to open it to the maximum angle in order to (expose) the working surface of the rod and bushing. In some models, this requires simply opening the sash wide; in others, you may need to temporarily remove the decorative plastic plug.
Apply lubricant pointwise. If you are using an aerosol, do not spray it directly at close range to avoid clouding the food or the interior walls of the chamber. It is better to spray the product onto a cotton swab or brush, and then carefully treat the rubbing parts. Pay special attention to the places where the metal rod enters the body - this is where friction most often occurs.
After applying the product, you must slowly open and close the door several times. This action will help distribute the lubricant over the entire surface of the mechanism and squeeze out any remaining dirt. Remove any leaked mixture immediately with a dry cloth. If after the first treatment the squeaking does not disappear completely, the procedure should be repeated after 15-20 minutes, when the composition will better penetrate the microcracks.
| Problem type | Recommended action | Treatment frequency |
|---|---|---|
| Slight squeaking | Cleaning and applying silicone spray | Once every 6-12 months |
| Strong metal grinding | Removing the door, removing rust, greasing | Immediately, then control |
| Sealant creaking | Wipe with glycerin or talcum powder | At each general cleaning |
| Mechanism jamming | Check alignment, replacement bushings | Repair required |
Do not forget to check the tightness of the door after completing the work. Sometimes excess lubricant can prevent the seal from closing tightly, resulting in loss of coolness. Wipe the outside of the hinges clean to prevent dust from sticking to them in the future.
What to do if a rubber seal squeaks
Sometimes the source of sound is not metal, but rubber. Plasma rubber loses its elasticity over time and begins to “stick” to the body of the refrigerator when closing, producing a slurping or creaking sound. This is especially true for new refrigerators or after a thorough wash, when the surface is degreased.
To eliminate this problem, you cannot lubricate the rubber with oil - it will destroy the structure of the material. The best solution is to use talc (regular baby powder) or a special rubber conditioner. You need to lightly powder the surface of the seal around the entire perimeter with talcum powder. This will eliminate the sticking effect and make the door move silently.
If the seal is severely deformed or cracked, no lubricant will help. In this case, the tires must be replaced. Also try wiping the seal with a vinegar solution to remove any grease that may be causing sticking. Regular care of rubber extends its service life and preserves the energy-saving properties of the equipment.
⚠️ Attention: Never use alcohol-containing liquids or acetone to lubricate the seal. They overdry the rubber, making it brittle, which will lead to depressurization of the chamber and breakdown of the compressor due to constant operation.
Lubricant features for different types of refrigerators
The design of the hinges may vary depending on the brand and model. In two-chamber refrigerators Indesit or Atlant the hinges are often hidden under decorative covers that need to be carefully pryed off with a knife or screwdriver. In models Bosch i Siemens the mechanism may be more complex, with closers that require caution during disassembly.
Refrigerators with the system No Frost have more massive doors due to additional insulation and fans, so the load is on their hinges above. Here you cannot save on lubricants - use only high-quality compounds with high anti-friction properties. Built-in appliances require special attention: access to the hinges there is limited by the furniture facade, so it is better to carry out preventive maintenance more often so that you do not have to disassemble the kitchen set.
If you have an old Soviet refrigerator, the hinges there may be open and often subject to corrosion. In such cases, a rust converter treatment may be required before lubrication. Modern models, as a rule, have protected units where preventive maintenance is sufficient.
Frequent errors when servicing doors
Many users, wanting how you can get rid of noise faster, they make mistakes that are then difficult to correct. The most common one is excessive lubrication. The excess flows down, stains the floor, attracts dust and creates a sticky layer that acts as a magnet for dirt. You need to lubricate with the thinnest layer, literally “spray” or drip drop by drop.
Another mistake is ignoring the skew of the door. If the door is skewed, then even the best lubricant will not completely eliminate the squeak, since the load on one of the hinges will be critical. Before lubricating, always check that the refrigerator is level and adjust the legs if necessary. The door should close on its own if you open it 45 degrees.
Also, do not use mixtures of oils. If you apply one product and decide to add another on top (for example, silicone on machine oil), a chemical reaction may occur, leading to the formation of hard lumps. Always completely remove old grease before applying new one.
Is it possible to lubricate the hinges without defrosting the refrigerator?
Technically, you can lubricate the hinges without defrosting, if access to them is open. However, if your model requires the door to be removed for proper maintenance, and the system does not allow you to turn off the fan or sensors without defrosting, it is better to perform a full defrost. This is also an excellent opportunity to clean the condensate trays.
How often should the lubrication procedure be repeated?
Preventive lubrication is recommended to be carried out at least once a year. If you live in an area with high humidity or there is a lot of cooking in the kitchen (greasy steam), the interval should be reduced to 6 months. Regular checking will help identify the problem at an early stage.
Will lubricant help if the door does not fit well?
No, lubricant eliminates friction and squeaking, but does not restore the geometry of the door. If the door is skewed or the seal is worn, you will need to adjust the height of the refrigerator legs or replace the sealing rubber. The creaking in this case is only a secondary symptom.
Is it safe to use WD-40 near food?
It is strictly forbidden to use WD-40 inside a chamber or where vapors can get on food. This is a chemical solvent. If you used it to clean the outside of the hinge, wipe the surface thoroughly and let it dry before closing the door for a long time.
Why does a new refrigerator squeak?
New refrigerators can squeak because the parts of the mechanism have not yet gotten used to each other, or because of shipping locks that were forgotten to be removed. The reason may also be the protective film on the seal. Usually, after a week of active use, the sound disappears on its own.
