Do-it-yourself whirlpool arc 4010 refrigerator repair

A favorable investment climate and cheap labor force lead to an increasing concentration of industrial production in the dynamically developing Third World countries such as Brazil. Whirlpool is one of the multinational corporations that have located large-scale production of household appliances in this country. The products of the company's plant in Joinville are now familiar to the Russian consumer as well.

Two-door refrigerators of the classic layout (freezer on top) of the ARC 4010/4020/4030 models have a No Frost system in the refrigerating and freezing chambers and an electronic control system.

The fan of the No Frost system is located in the freezer, from which the cooled air enters the air distribution device (diffuser) on the rear wall of the refrigerator.

The main technical characteristics of these refrigerators are given in table. one.

A review of The Bodyguard starring Colin Farrell was supposed to appear on this site this morning. But, waking up closer to lunchtime to Jack Sparrow's shouting "Go to places, the dogs are garbage!", I walked sleepily to the refrigerator and found that the lazy cattle had stopped working.

My first thought was to run to the store for a new one, but I was stopped by the alarming roar of a hungry beast, coming from the depths of my stomach.

From the contents of the refrigerator thawed overnight in a warm state, only Bestuzhev could be consumed,

which I did not fail to do.

Having dined, I decided not to flog a fever and to think it over properly.

As a result, I didn’t run to any store, because after “Bestuzhev” my legs were treacherously braided. I just figured it would be nice to apply my colossal experience in installing, repairing and maintaining air conditioners to revive the old Whirlpool.

According to the good old tradition of previous repair publications, I try to do with the least amount of tools, since a fierce set of craft gadgets is rarely found in an average Russian family.

In today's opus, we need surprisingly little - the most ordinary tester, a pair of Phillips screwdrivers and basic knowledge from the school physics course.

I hope every reader of this article has this modest baggage.

By the way, do not be embarrassed if your broken refrigerator is not like the author's. The principle of operation and design of the No Frost single compressor system is identical on all models.

Step # 1 - check the compressor

The most expensive and technologically complex unit of any refrigerator is the compressor. If it breaks down, Whirlpool can be safely thrown into the trash due to the high cost and inappropriateness of subsequent repairs.

Fortunately, the most expensive part of a refrigerator is incredibly easy to test.

We free the refrigerator and roll it away from the wall.

To remove the protective cover of the compressor, you need to unscrew the four bolts.

Compressor contact group.

The yellow / green wires are ground. Brown and blue, extending from the white braid, are powered from the mains. The black and second brown, going to the compressor, supply power to the compressor. Blue and black are already closed.

You don't need to be seven inches in the forehead to understand - to start the compressor in manual mode, it is enough to disconnect the contact group,

and with a piece of wire,

close the contacts of the two brown wires.

Then feel free to plug the plug into the outlet. If the compressor is silent, it's time to run to the store for a new refrigerator.If it works, go to step # 2, remembering to connect the contact group back, put the back cover on and slide the refrigerator into place.

Step # 2 - checking the fan

Since our old Whirlpool is a No Frost system, there is a fan in its design that drives cold air from the evaporator inside the freezer.

In any refrigeration equipment, the compressor supply circuit is always tied to the fan, so that if the latter fails, premature freezing of the evaporator tubes does not occur.

Open the freezer and remove the back wall with a fan.

There are only two contacts on it, to which you need to supply power.

You can use a broken cord from an old electrical appliance to supply power.

The polarity does not matter; in the worst case, the fan will spin in the opposite direction.

If, after energizing, the blades are spinning, go to step # 3. If not, we move to the spare parts store, the malfunction has been identified.

Step # 3 - checking the thermal fuse

So, take a close look at the freezer compartment.

It is quite easy to find the temperature fuse - a metal cylinder sealed in transparent plastic.

This fuse breaks when the evaporator defrost heater overheats. We disconnect the plug and check it with an ordinary tester.

From this, it can be indirectly concluded that the evaporator temperature sensor is also in order!

We put the fuse in place and assemble the freezer. It's time to move on to step # 4.

By the way, if the temperature fuse shows an open circuit, replacing it alone is not enough. It is necessary to figure out why the heating element is overheating. In most cases, the reason lies in the defrost timer, and therefore it will also be useful for you to familiarize yourself with the next point.

So, we checked almost all the components of the refrigerator, but we still did not find the problem. We climb into the refrigerator

and remove the control unit for cooling modes,

which contains a lighting lamp (left) and a thermostat with a timer (right).

For further manipulations, the electrical circuit of the refrigerator, which is glued on the back wall, will greatly help.

It can be seen from the diagram that there is nothing to break in the thermostat, while the timer is teeming with a set of connectors and closes the fan and compressor power circuits.

Fortunately, I have it mechanical. It is better to send the electronic timer to the service immediately for diagnostics.

Before removing the contacts from it, it is advisable to sign the color of the wires with a marker.

Now we are carefully studying the scheme.The red / brown wire from the thermostat should be shorted to the brown wire that supplies power to the compressor and fan.

We disassemble the timer by carefully removing the top cover from it.

Now the blue and brown ones are closed, the power to the compressor and the fan will not be supplied to the network when the refrigerator is turned on.

We turn the drive gear with a slot for a screwdriver a millimeter clockwise. The contact closes the red-brown and brown wires.

We assemble the temperature control unit and turn on the refrigerator. Working.

You can now fill the old man with food.

The malfunction turned out to be the simplest - the drive gear of the mechanical timer of the refrigerator was stuck.

As you can see, it is possible to make an initial diagnosis of a failed refrigerator at home. And if thanks to this manual you manage to fix it, the author's joy will be unlimited, and his hand will reach for ...

All the best, and see you again on the pages of the site, friends!

A refrigerator is a household appliance that has a rather complex structure. All functional units are combined into one system filled with a special gas. With the integrity of the system, the device performs all its functions and works without failures and breakdowns. But you can always run into problems, therefore, possible malfunctions in Whirlpool refrigerators and options for solving them in some cases and on their own... After all, you don't want to take your favorite device to the workshop when you can fix some of the faults yourself.

It is worth noting that the Whirlpool trademark has been loved by the user for a long time, as their refrigerators are durable and easy to use. At the same time, they have established themselves as convenient and functional devices. And it is not surprising, because only the newest are used in the production of equipment. Energy Saving Technologieswhich allow Whirlpool refrigerators to work for a long time without breakdowns.

But even such reliable devices have failures and malfunctions. Experts identify the most common types of breakdowns of Whirlpool brand equipment.

• breakdown of the electronic unit, which is responsible for control;
• temperature failures, which can be represented by the formation of ice or moisture;
• freezer compressor failure;
• loose door closing.

Refrigerator malfunctions often occur due to improper operation. Such breakdowns can always be eliminated on your own - for this it is worth familiarizing yourself with the instructions attached to the technique and observing all the points that are indicated there during further use. This small list does not mean at all that such breakdowns will appear during the operation of the refrigerator, but different things can happen, so it is worth considering the malfunctions of Whirlpool refrigerators in more detail.

Malfunctions in the refrigerator can be very diverse, but it is possible to draw up a specific list of problems that the user encounters most often.

The following problems can be grouped into this group:

• the device itself does not turn on, but the light comes on;
• the device does not turn on, even the light does not come on;
• it turns on, but after 5-10 minutes it turns off by itself.

The described problems are typical for heater breakdowns., temperature sensors, timer. If you have electrical engineering knowledge, then it is quite possible to ring the electronic circuit of the device and identify the faulty element. Very often, when you turn on the refrigerator and then turn it off, you can observe the appearance of characteristic oil stains on the floor, indicating a compressor malfunction.

Most often, such malfunctions of Whirlpool refrigerators can be found if the No Frost system is present. Such models are quite complex in their implementation and, as a rule, malfunctions occur precisely in them.

Refrigerator compressor repair

The second most common are breakdowns:

• the freezer does not freeze, but simply cools, while in the refrigerator compartment there is a normal cold temperature;
• the refrigerator compartment is not working and the freezer is functioning perfectly;
• appears on the walls fur coat or bloat.

There are a lot of reasons that can lead to this state, for example:

• breakdown of the thermostat or fan of the No Frost system;
• freon leak;
• damage to the motor-compressor;
• evaporator problems;
• clogged filter.

To establish the exact cause, a professional diagnosis should be made.

Timer thermostat (right)

Owners of electronically controlled refrigerators often encounter such malfunctions as a breakdown of the thermostat or clogged drain tube, which lead to the formation of water. Malfunctions of this type can be caused by the fact that a faulty sensor does not give a timely signal about an increase in temperature, and the motor does not readjust to the desired operating mode.

Very often, many malfunctions occur without any special visible signs, so it is quite difficult to visually determine what is broken.Professional help is needed here.

Drain tube (drain tube) location options

Among such breakdowns, the following are most common:

• the refrigerator makes too loud a sound during operation;
• the door does not close tightly;
• damage to fittings.

Such malfunctions often arise due to trivial mechanical damage. Sometimes it is enough to carefully examine the unit to find the cause of the strange sound: perhaps the fasteners of some unit are loose or a foreign object has got into the device. Loose door closing may be due to deformations gum sealantthat could be caused by liquid spills.

Details about such problems are described in the recommendations for the operation of Whirlpool refrigerators.

It is always worth remembering that even the slightest malfunction of the refrigerator, which, in principle, does not disrupt the cooling and freezing processes of food, over time can cause great harm to the nodes that are not yet damaged. This happens as a result of the fact that "healthy" nodes receive increased load, which leads to their faster wear. If, during operation, the owner noticed that the refrigerator has changed its work, rattles, does not freeze enough or simply works outside the box, then you should definitely seek the help of specialists who are able to fix all failures in the shortest possible time.

Whirlpool refrigerators have gained worldwide fame. They are beautiful, functional and reliable. But any technique can have a latent defect that manifests itself during operation. In quantitative terms, Whirlpool refrigerators do not come in for repairs more often than others. Typical malfunctions are associated with freon leakage, electronic control and clogging of the condensate drainage system.

The main purpose of refrigerators is to create the required temperature in the refrigerator and freezer. If the temperature in the plus cabinet is such that the food freezes or is higher than the set one, it is necessary to find the reason. For this, all nodes participating in the process are checked:

• operation of the control unit;
• serviceability of the thermal sensor and thermal relay;
• tightness of the cooling circuit;
• compressor state - duration of switching cycles, extraneous noise;
• the presence and amount of isobutane in the system is established:
• the correct operation of the condensate drainage circuits.

All of these factors can cause a disturbance in the cold chamber operation.

The electronic control unit is the most vulnerable part in case of unstable voltage in the network. It is possible to find a malfunction in advance, if there is no reaction to the commands, error codes appear chaotically, the panel does not respond to the shutdown button.

A faulty temperature sensor will not give a signal to start the compressor or stop it at a given temperature. The cabinet heats up to room temperature or freezes. It depends what position the compressor was in before the sensor failed.

The geared motor may not turn on if the starting relay is faulty or the motor is faulty. The unit may hum strongly when the compressor is jammed, but overheating, it will shut down.

Lack of freon will force the compressor to work non-stop, but there is not enough cold, the temperature rises. It also rises when the cold wall in the cabinet is covered with a snow coat - the condensate defrost system is faulty, the evaporator sensor or heater has failed. But the "fur coat", accompanied by the swelling of the cabinet walls, also indicates a refrigerant leak.

There are many reasons, even the incandescent bulb inside may not turn off, adding heat to the camera. By following the instructions, all user-dependent factors must be excluded. The diagnostics must be entrusted to a service center specialist.

The freezer is designed for long-term preservation of cold in autonomous mode. If it shows signs of defrosting, the circuit has been inactive for several hours. To find the cause, it is necessary to completely defrost the chamber and dry it. If after switching on the cold is not recruited, and the compressor is working, there is no freon in the system. A leak has occurred due to a leak in the circuit. Another reason for defrosting can be:

• failure of the electronic control module;
• sensor failure;
• compressor malfunction - insufficient gas compression.

If the cold builds up, the chamber freezes, you need to make sure that the condensate removal system is working correctly. There is no melting of frost, freezing of the evaporator begins, poor heat dissipation. A specialist will help you find the reason why the Whirlpool refrigerator does not produce enough cold for the freezer.

A typical malfunction of an overseas refrigerator is considered a failure of the defrosting system of a cold cabinet. At the same time, the No Frost system detects a malfunction with one of the following signs:

• the compressor works constantly, which means that there is no defrost interval, the walls of the chamber are frozen over;
• there is not enough cold in the plus section, drops of water flow down the back wall in the freezer;
• On the board there is an emergency signal and sound notification.

In the refrigerating chamber with a drip defrosting system, condensation does not come off, the hole is clogged. If the cause is not eliminated, ice will begin to freeze at the bottom of the chamber, the defrost system will become unusable. Sometimes the water does not come out because the drain tube is clogged or frozen over. The water will then flow downward, forming ice in the freezer.

A puddle that has formed under the refrigerator indicates a malfunction of the drainage system. The condensate is discharged through a rubber-sealed tube. It is directed to the chute mounted on the compressor. During operation, the power unit is hot, the liquid evaporates. But a crack in the tube may appear, the bowl may budge or bend over. All the water will be under the refrigerator.

You can correct the vessel yourself. It is necessary to correctly install the tubing using the cuff. In this case, you need to inspect the system for other damage. A wizard will be required if you were unable to eliminate the condensate leak.

Single compressor refrigerator with bottom freezer and electronic control. The temperature is maintained by a mechanical regulator. The green LED indicates that it is connected to the network. Red - temperature rise in the freezer. The orange LED is on when the freezer is set to hard freeze. Manual thermostats for cameras are located under the control panel cover.

Freon leakage is a typical malfunction of this model. The high pressure tubing is routed in the foam section between the chambers. When the drain from the refrigerator is clogged, water penetrates into the foam, the tube corrodes. As a result of the repair, the circuit is removed from the foamed part, the system is filled with isobutane (R600a).

Two-compartment refrigerator with one compressor and a 110 liter freezer. The body is made of stainless steel. The No Frost system is used in the freezer. Electromechanical control.

Typical malfunctions of the Whirlpool ARC 4190 ix refrigerator include:

• problems with the defrost and condensate removal system;
• failure of the evaporator heater or defrost timer;
• control board failure.

The refrigerator has one evaporator installed in the freezer.During defrosting, water flows into the drain located behind the decorative panel. If there is a problem with the removal of condensate, it is necessary to clean the hole and pipe.

There is snow in the freezer - you need to check if the heater is working when the compressor is resting. This cycle depends on the defrost sensor, which gives the command to turn on the heating element with a build-up on the evaporator tubes up to 0.5 cm thick. Sometimes defrosting and drying the refrigerator during the day will help eliminate leakage.

As a result of a power surge, moisture on the panel, the electronic control unit may fail. Therefore, you cannot put fresh flowers on the refrigerator - you can accidentally spill water.

Two-compartment refrigerator with a small freezer located on top. Refrigerant freon, electronic control. Both chambers use the No Frost defrost system.

Malfunctions that may occur during the operation of the refrigerator are reflected in the section of the instructions "Troubleshooting Guide". The developers advise first to independently check the reasons for the refusal using step-by-step instructions.

Electronic self-diagnosis of faults will help to draw attention to the problem. So, if the Whirlpool refrigerator beeps, this is a signal of a violation of the temperature regime inside the chamber, caused by a depressurization of the circuit. If the door is closed, the seal is not worn out, the abutment is good, the door opening sensor, condenser should be examined. They are located inside the control panel.

If the Whirlpool refrigerator does not work, malfunctions are possible in any node, but the most common cause is freon leakage, damage to the electronic unit and the failure of the Know Frost system.

Two-door two-compartment refrigerator with an overhead freezer and a Nou Frost defrost system. Electromechanical control system. Opening and incomplete closing of the door is accompanied by a sound signal.

The problem is if the regime is violated. This is due to various reasons. This model has a problem with starting the compressor. At the same time, attempts to turn on are accompanied by clicks of the relay. The cause may be a faulty starting relay or a burnt out motor winding. This is evidenced by the fact that at start-up, the compressor turns off without even having worked for 30 seconds.

Failure of the control module is a real reason for voltage drops in the network and work without a stabilizer. However, isobutane leaks or capillary tube clogging is possible.

All refrigerators with the Know Frost system have problems with defrosting and removing condensate.If there are remarks about the operation of the device, it is necessary to free the chambers from food, defrost, dry and try to start again. If the mode is not restored, contact the service center.

Single-compressor combined refrigerator, freezer below, installed No Frost system and electronic control with a display on the external panel. The model refers to those where self-diagnosis and maintenance of a constant mode "6th sense" is installed. The error codes are listed in the operating instructions, in the troubleshooting section of the Whirlpool ARC 8140 refrigerator. If you need to reset any of the errors, press the "OK" button and hold for at least 5 seconds.

Often the problems of this model are a malfunction of the control module, lack or lack of refrigerant. In the defrosting system, the heating element for defrosting the evaporator fails and the fan breaks down.

Having become acquainted with the listed models, the conclusion suggests itself - Whirlpool refrigerators have a prestigious appearance, good functionality, but the models are vulnerable when connected directly to the network. Their energy unit may break down, leaks in the refrigerant circuit may appear. With proper operation, Whirlpool household refrigerators serve for a long time. Troubleshooting is performed by the service center masters. Spare parts are expensive.
