20 solutions if the refrigerator does not cool or freeze

Food spoilage and a great deal of frustration can result from your refrigerator not cooling or freezing properly. Gaining insight into the cause of your refrigerator’s malfunction can help you quickly resolve the issue and get your life back on track.

A refrigerator may not cool down or freeze for a number of common reasons. Certain problems are easy to fix, such as cleaning the vents or adjusting the thermostat. Others might need further troubleshooting, like inspecting the condenser coils or checking the door seals.

This guide will go over 20 workable fixes to assist you in identifying and resolving refrigeration issues. These steps will help you find the source of the problem and possibly avoid having to replace or repair expensive equipment.

Reasons

You must be aware of the primary malfunctions’ characteristics. This will assist you in determining whether to seek professional assistance or attempt the repair yourself.

The cord is pulled out

Make sure the device is connected to the power grid and that the power indicator is on before contacting a technician. It might turn out that everything is fine and that all you need to do is plug your two-chamber buddy into the outlet.

The door is not closed

The device’s performance will be considerably diminished by even a small space between the door seal and the body. Verify that the door fits securely.

The seal is torn or hardened

You will need to purchase a new rubber gasket if the existing one is torn. Look for the original component.

It’s not necessary to replace the seal right away if it’s become overly hard from age or certain household chemicals. You can attempt to reestablish elasticity with makeshift methods. The techniques are inexpensive and easy to use.

Initially, the rubber must be removed:

1. Today, the seal is usually secured with foam, glue, or inserted into a special groove. Dismantling in this case does not cause any particular difficulties.
2. In Soviet models, the rubber is mounted on nails or rivets. When removing, you must act carefully so as not to damage the element.

You must scald the rubber with several liters of boiling water in order to restore its elasticity.

Until the hot liquid cools completely, leave the seal in place. This process frequently aids the rubber in regaining qualities that it has lost over time.

The defrost mode is on

The refrigerator may occasionally be in the defrost mode and you fail to notice it or simply forget it. All you have to do is flip it to cooling mode.

The temperature is set to high

The temperature in the upper positive chamber may rise on a hot summer day when sunlight is present. For optimal performance, you should modify the thermostat in consideration of variations in outside circumstances.

Setting it to maximum in hot weather is not recommended as the compressor can malfunction.

The temperature sensor is broken

Modern refrigerators frequently have malfunctioning temperature sensors if they don’t freeze. The "electronic brain" receives false signals, which prevents the system from signaling the compressor to turn on. Although a new one is less expensive, the sensor’s quality directly affects how long it will last.

The so-called thermal relay (thermostat), which malfunctions in older equipment, can be repaired further here.

The compressor motor burned out or overheated

The following indicators indicate a failed compressor motor:

1. When you open the door, the light comes on, but the refrigerator itself does not work and does not cool the food.
2. The motor turns on and almost immediately turns off. Before turning off, you can hear the relay click (more about strange sounds). The light is on, but none of the chambers freeze.
3. The electric motor hums, but there is no cooling.

The element must be changed in the event of such a breakdown.

The device might not freeze if the compressor overheats. Usually, the starting relay’s failure is the root cause. You must get in touch with a specialist for repairs.

The fan is frozen

This issue could arise in gadgets that have the No Frost system installed.

1. If the fan in the device is frozen, the temperature regime of the entire cooling system is disrupted. This happens extremely rarely, a complete defrosting will help.
2. The fan runs continuously, producing a characteristic buzzing sound. The system cannot cool the chambers to the required temperature due to ice frozen in the air passages. To solve the problem, it is necessary to defrost the refrigerator for 12 hours.

Freon leak

To fix the problem, locate the leak, replace the filter and dryer, and add more freon to the cooling system.

The release of cooling gas in single-compressor models may be indicated by the following symptoms:

1. After defrosting, the light inside the chamber lights up, but the refrigerator does not freeze and does not turn on.
2. The compressor runs constantly, but the device does not cool well.
3. After defrosting, the unit worked for a little while, but then turned off and does not turn on.

The indications of leakage in dual-compressor models are identical, but they only apply to the freezer or top compartment.

It typically happens in the heating circuit, the evaporator, and the locations where the tubes are soldered. You can read more about this here.

Electronic unit glitches

The refrigerator may behave erratically or not at all when the control unit fails. There will be temperature jumps in various chambers. The gadget might briefly turn on before shutting off once more.

Modern models alert users to the temperature increase with sound or light signals, such as when the red LED blinks or illuminates.

On the liquid crystal screen, those who have a display show a text message with an error.

Moisture intrusion is the most common cause. This typically occurs when defrosting. The control module needs to be fixed or replaced entirely.

Dead defrost heating element

Ice can occasionally build up in the heat-removing air cavities of a refrigerator if it doesn’t freeze. This occurs when the heating element burns out in these cavities, causing the ice to defrost.

Defrosting the chambers is required in order to diagnose the issue, after which the heating element’s functionality must be examined. This is a common element that facilitates the melting of snow and ice.

Damage to the evaporator

The back wall radiator, or evaporator, may have the following issues:

1. Oil clogging. To eliminate the malfunction, it is necessary to unsolder the system where the compressor and capillary tube are connected. The evaporator, capillary and suction tube are washed with liquid freon.
2. Freon leak. The evaporator needs to be replaced.
3. The refrigerator operates continuously (does not turn off temporarily). This indicates that there is no contact between the evaporator suction tube and the thermostat siphon tube.

The capillary tube is clogged

In older models of refrigerators, capillary tube clogging is a fairly common problem. The circuit is the part of the device that is most susceptible to damage.

Though extremely difficult, it is still possible to repair at home.

To begin with, make sure you have all the equipment and tools needed to fill freon and refrigerant. You must get in touch with a service center if you don’t have all of these.

Various plans exist for self-maintenance:

1. Do not clean, but cut out the clogged part of the circuit. The cut is made approximately 20 mm from the place where freon enters the capillary. This repair method is not suitable in cases where the blockage is much further.
2. Clean the tube using compressed nitrogen. It is necessary to inject in the opposite direction from the movement of freon. A blow-off press is needed for repair.
3. If blowing does not help, dismantle the evaporator, heat it in hot water and repeat the procedure.
4. Cut the tube from the filter. A copper tube with an internal cross-section of 6 mm is soldered to the cut side. A pressure gauge on a hose is connected to it, and then the entire structure is attached to the discharge outlet. Before performing the last step, pour about 10 ml of solvent into the hose. The motor turns on until 25 atmospheres reach, and then turns off. If the blockage remains, the procedure is repeated. In some cases, up to 30 cycles are required.

Should the provided techniques prove ineffective, replacing the capillary system will be necessary.

Oxidation and rust inside and out of important modules

When repairs are not done correctly into a hermetically sealed system, moisture seeps in and corrodes the tube walls, creating micro-firmness that allows refrigerant to escape into the surrounding air. The freezer’s temperature progressively rises. Just the damaged areas’ drainage to new is done here.

The compressor will eventually break from continuous operation if you fail to address the issue in a timely manner.

Rust converters are used to get rid of corrosion spots outdoors. You can find them in specialty shops. Additionally, you can use nine percent vinegar in place of a means.

Mechanical and chemical damage

There may be cracks and holes in the body. When something is moved, improper transportation is usually the cause of this kind of damage.

Holes allow warm air to enter the refrigeration chamber. The compressor runs continuously but is unable to cool the chambers because the temperature does not reach the necessary level.

You can fix small cracks on your own. It is necessary to defrost and dry the device. The damaged area is removed and replaced with fresh insulation, such as foam fragments. Polyurethane foam can be used to hold the pieces in place; once it hardens, trim off any excess.

It should be kept in mind that certain places are more likely to experience cracks. These are the locations of all fasteners, including doors. Breakages may result from bolts that are overtightened.

Most often, chemical damage happens when washing. Use of aggressive chemicals is prohibited. It is necessary to repair any externally applied enamel damage in order to stop rust from spreading.

If the No Frost system is installed

Nearly every challenge mentioned above also applies to models that have the No Frost system.

1. Freon leak.
2. Compressor failure.
3. Failure of the thermostat.
4. Failure of the heating element.
5. Fan freezing.
6. Incorrect operation of the control unit.

It is best to get in touch with an expert to avoid breaking anything else. One should only attempt independent repairs if one has a rudimentary understanding of this field.

Question and answer

After a power surge

1. Check the RCD and circuit breakers on the panel in the apartment or house, perhaps the “plugs” have simply blown.
2. If it does not freeze after a strong voltage drop, the network filter built into the housing has failed.
3. The motor winding has burned out.
4. The electronic control board has burned out.

Be cautious, the final three issues will need major repairs.

After moving or rearranging

Recall that you did not drop it on its side or strike it on a hard surface while dragging?

• If it falls on its side, there is a risk that the motor inside the compressor unit (that black thing at the back under the radiator) will fly off the spring-loaded guides, bend the tubes and the system will stop cooling.
• The loaders hit the radiator against the wall and the circuit became depressurized. There will be a specific unpleasant smell. You will have to look for a leak and refill the freon.

The problem is observed after defrosting

Do not panic if your unit stops cooling after defrosting. Maybe it’s just reaching the right temperature. Hold off for a day or so. The device will revert to operating mode during this period.

One of the issues mentioned above has happened if, after a day, the issue has not been resolved and the engine is operating virtually continuously. In this scenario, you will need to identify the issue and fix it.
