How to fix the refrigerator?

Household appliances have become firmly established in our everyday life. There are things without which you can do without effort, but there is, without exaggeration, and essentials. In particular, the failure of the refrigerator causes the owners a state close to panic. The theme of today's article is how to fix a refrigerator. It turns out that there are situations when you can repair the device yourself without contacting the service center. Fortunately, these units are arranged so that most of the failures can be eliminated.

What can I repair myself?

In the refrigeration unit, you can identify several circuits, or design systems.

refrigeration system You can only try to repair it yourself in one case: if there is no way to call a specialist. Before you start repairing the refrigerator with your own hands, at least in the first approximation you need to know how the system works and on what principle.

Important! Careless or incompetent repair is fraught with irreparable consequences. So, if you do not want to go for a new unit - do not try fate better.

The thermoregulation system

Here everything is somewhat simpler. Many home masters carry out this repair themselves. However, to begin with, compare the purchase price of the spare part and the call of the service center employee. Add to this the loss of time and the associated discomfort( most likely, you will need to order spare parts in the online store).

Electrical system

Here the playful handles of the home craftsman have where to go for a walk. Repair is possible and is not particularly complicated. Also, you will not need complicated tools. A tester and a soldering iron are enough. Well, you still need to make it yourself. Repair of refrigerators with their own hands for beginners - than not a way of self-affirmation?

Mechanical system

This includes fasteners, suspensions, seals, etc. There are cases when self-repair is possible.

How

works Depending on the cooling methods, the units are divided into 3 categories.

• Compression.
• Adsorption.
• Thermoelectric( they are also called semiconductor).

Important! The first two categories use liquefied refrigerant. The last category is electrical appliances, devoid of valves and pipelines.

The most common category is compression devices, but on the market are all 3 varieties. Let's take a closer look at the operation of the compression unit:

• With the instrument on, the gas is sucked in by the compressor, and then, passing through the condenser, is compressed.
• In the condenser, the gas is cooled and liquefied.
• The further way of the liquefied gas passes through the drying filter, further - in the evaporator. There is a rapid expansion of liquefied gas, with a sharp decrease in its temperature.

Important! This process continues cyclically until the device is disconnected from the power supply.

How to use the refrigerator correctly - recommendations:

• The right place for installation. If the instrument location is unsuccessful, it needs to work for a long time to ensure the desired temperature. The condenser located in the rear of the refrigerator must be cooled by air currents. For this reason, do not place the appliance near a stove or a heater. Otherwise - often you will think that you need to fix the refrigerator.
• In order to avoid the multiplication of harmful bacteria, the cooked food should be stored in the upper part of the refrigerating chamber, and the raw foods in the lower part. Store meat and fish in plastic containers or in a plate covered with another plate.

Important! The coolest part in the refrigerator is the one that is located near the evaporator.

• The products in the freezer must be stored wrapped or in food containers. Can be stored in foil. Liquid products are stored in plastic containers. It is desirable to paste labels on all products with the date of freezing.

Important! It must be remembered that for different foods there is a different period of freezing.

• Freezer thawing. The work on defrosting the refrigerator can not be pleasantly named, but it is necessary to do it periodically. Even if the unit is equipped with an automatic defrosting system. It is desirable to defrost when the refrigerator is loaded with food at a minimum.

Important! Do not allow the thickness of the frozen ice to exceed 0.5 cm.

• Do not use the knife and other metal objects when defrosting the unit. As thawing, clean the ice with a spatula made of wood.
• Do not neglect to clean the refrigerator! Wash its internal surfaces at least once a month, using soft liquid detergents. Use detergents for seals can not. The use of special antibacterial aerosols in the process of cleaning the interior surfaces from contaminants is welcome.
• Monitor the condition of the drainage channel and the drainage hole. Allow them to clog.
• To ensure that the smell is not "preserved" smells( including, and not very pleasant), make sure that products with a strong odor are tightly closed.

Important! You can use the brand-name deodorizer, which allows you to keep the smell of freshness for a long time. If there is no possibility to purchase a special remedy, put a glass of soda in the refrigerator. This is an excellent natural adsorbent.

The most common malfunctions and their elimination

Consider the most common failures that can be eliminated on their own.

Noise when operating the

unit. Of course, the refrigerator can not be called an absolutely noiseless device, but sometimes decibels are called "off scale":

• Often the cause of excessive noise is the uneven placement in the refrigerator of bottles, plates, pans, etc.
• Sometimes the cause of a strongThe vibration is that the device is installed unevenly. The problem can easily be eliminated by adjusting the legs in height.
• Sometimes it may be necessary to repair the compressor of the refrigerator with your own hands. Noise may occur due to the wear of the compressor rubber feet. To unpleasant sound background is gone, replace them with new ones or simply pull up.

"Puddle" in the refrigerator

The water in the bottom of the refrigerating compartment is quite common. The reason is that the drainage channel is clogged and water is not drained through the drainage hole.

You can clean it with a special device that comes with the cooling unit. If this device is lost, you can use a children's syringe. Type a little water into the enema and "pore out" the hole. Observe if water is not accumulating in the refrigerator. If - no, it means - you did everything right.

The door of the freezer does not open

Do not panic! You do not need to repair the freezer yourself. The vacuum holds the door firmly. Wait a while and try again.

The refrigeration chamber is not illuminated.

To start, press the light switch several times. If the lighting does not turn on, you will have to replace the light bulb. The procedure is as follows:

1. Disconnect the appliance from the mains.
2. Remove the cover from the light bulb.
3. Unscrew the bulb. If it is burnt out, replace it with a new one.
4. Install the cover in place, fasten it to the clips.

Important! Install only those lamps that are provided by the instruction manual.

If, when inspecting the lamp, it turned out that it is in working order, then the problem is in the switch itself. To repair it:

1. Carefully unscrew the fasteners and remove the switch case.
2. Now remove the wire from one of the leads and touch the tester.
3. If the device shows "infinity", if the device button is not pressed, the device is defective.
4. Replace the switch and reinstall it by fastening the fasteners.

Insufficient cooling

Causes may be as follows:

• Incorrect temperature set. Rotating the thermostat knob, set the desired cooling temperature.
• The room temperature is too high. The heat should just wait. And if the device is installed near the heater, think about another place of its location.
• Thermostat is defective. Repairing the refrigerator thermostat with your own hands is a risky and thankless task. Call the wizard.
• The dust on the condenser has accumulated. As a result, the heat exchange between the condenser and air is disrupted. The refrigerant cools down worse than necessary. Remove the dust with a soft textile or vacuum cleaner, and the refrigerator will work.

Important! Before cleaning the condenser, be sure to disconnect the appliance from the mains.

The

door seal is worn. A worn seal causes air to enter the refrigerating compartment and the air does not cool down as needed. The simplest case of repairing an "Ardo" fridge or any other brand with your own hands is a replacement of the seal.

It is more difficult if the seal can not be replaced. I'll have to change the door completely.

Important! If the correct seal is not available, you can buy a universal one.

The device works, but does not cool

Most likely, the problem is a malfunction of the thermostat, violation of the pipeline's passability and the leakage of refrigerant. If the faulty thermostat can be replaced, then the repair of the pipeline and the recovery of the refrigerant is associated with finding the fault location, evacuating the refrigerant from the system and refueling.

Repair the refrigerator in this case only a professional can.

Excessive temperature

Reasons may be as follows:

• Incorrect temperature setting. Adjust it with the thermostat knob and the problem is eliminated.
• Non-activated fast freeze mode. If your refrigerator is equipped with this function, check that this mode is turned off.
• Thermostat fault. Call the master - he will replace the defective part with a working one.
• Automatic defrost heater defective. A specialist can also repair the refrigerator here.

The device "does not give signs of life"

Again, without panic."The patient is more alive than dead."Probably, the reasons are as follows:

• The plug has moved away from the socket. Is it funny? Not really. Calling the master with such a "malfunction" is by no means a rarity.
• Malfunction in the outlet. Hence the lack of power.
• Wire break.
• Fuse in the power plug is defective. If the reason is this, then the fuse can be replaced.

If the above items are all within the norm, call the master.

Perhaps the topic of repairing refrigerators with their own hands for beginners is exhausted. Good luck with the repair of household appliances!
