Why the Whirlpool refrigerator does not freeze: a complete analysis of the reasons and solutions

The refrigerator Whirlpool stopped freezing, and food is thawing in the freezer? This problem is familiar to many owners of American brand equipment. The reasons may lie in both trivial operating errors and complex technical malfunctions. It is important to quickly understand the situation in order to prevent food spoilage and avoid expensive repairs.

In this article we will analyze in detail all the possible reasons why a refrigerator Whirlpool (including popular models WRB322DMBB, WRT311FZDW, WRX735SDHZ) may stop freezing. You will learn how to diagnose the problem yourself, what manipulations can be performed without calling a specialist, and in which cases it is better to trust the professionals. We will pay special attention to specific “diseases” of equipment Whirlpoolthat are not found in other brands.

Let us note right away: if your refrigerator is does not turn on at all, this is a different story. Here we are considering precisely the cases when the equipment works (buzzes, the light inside is on), but does not cool or does not freeze hard enough. Let's start with the simplest and most obvious reasons, gradually moving on to more complex ones.

1. Operating errors: what you might have missed

Before committing a breakdown, check whether the lack of cold is due to improper use of the refrigerator. Whirlpool - equipment is sensitive to operating conditions, especially models with a system No Frost.

Start with the basics:

• 🔌 Power: Make sure that the refrigerator is connected to the outlet and it works (try turning on another appliance). Sometimes the plug may fall out of the socket a little, especially if the socket is old.
• 🌡️ Temperature mode: Check whether the freezer is set to Defrost (defrost) or Vacation (vacation). In some models Whirlpool these modes are activated by accidentally pressing buttons.
• 🚪 Closing tightness: The door may not fit tightly due to a skewed hinge, a worn seal, or simply because it was overloaded with products. Check to see if the light inside is on when the door is closed.
• 📦 Overload of products: If you have recently loaded a lot of warm food (for example, after shopping), the compressor may not be able to cope. Give the refrigerator 6-8 hours to restore temperature.

Pay special attention to display (if any). In models Whirlpool with electronic control (for example, WRX988SIBM), codes F1, F2 or F7are often displayed when operating errors occur. We will provide the decoding of these codes in a separate table below.

2. Problems with the door seal: how to check and fix

A worn or dirty seal is one of the most common causes of poor frost. In refrigerators Whirlpool the seal often loses its elasticity due to temperature changes, especially if the appliance is located next to a stove or window.

How to diagnose the problem:

1. Take a sheet of A4 paper.
2. Place it between the seal and the body refrigerator.
3. Close the door and try to pull out the sheet. If it comes out without effort, the seal is not sealed.

Check the seal around the entire perimeter. Pay special attention to the corners - this is where gaps most often form. If the seal is dirty (you can see plaque or sticky spots on it), you can try cleaning it with a soap solution. If the rubber is cracked or deformed, replacement is necessary.

In models Whirlpool with a system Adaptive Defrost (for example, WRF535SWHZ), a leaky door can lead to icing of the evaporator and malfunction of the fan. If you notice that the refrigerator has begun to thaw more often or ice has appeared on the back wall, this is an indirect sign of problems with the seal.

3. Malfunctions of the thermostat and temperature sensors

The thermostat (or thermostat) is the “brain” of the refrigerator that controls the temperature. In Whirlpool electronic sensors are often used, which can fail over time. If the thermostat is faulty, the compressor either does not turn on at all, or works without stopping, but does not cool.

Signs of a broken thermostat:

• 🔄 The compressor turns on for 5-10 seconds and immediately turns off.
• 🌡️ Temperature in chambers does not correspond to the installed one (for example, they set it to -18°C, but in reality -5°C).
• ❄️ A “coat” of ice forms on the back wall of the refrigerator compartment.
• 🔊 The refrigerator makes clicks, but the motor does not start.

B models Whirlpool with a display (for example, WRB322DMBB) if the sensor malfunctions, an error F3 or F5may be displayed. Check if the temperature indicator is flashing.

How to check the thermostat yourself:

1. Unplug the refrigerator.
2. Remove the protective cover (usually it is located inside the refrigerator compartment, next to the lamp).
3. Find the thermostat - this is a small box with tube attached to the evaporator.
4. Carefully remove the terminals and check the resistance with a multimeter. At room temperature, it should be within 2–5 kOhm.

Where is the thermostat located in the Whirlpool WRX735SDHZ refrigerator?

In this model, the thermostat is located behind the plastic panel in the upper part of the refrigerator compartment, on the right. To get to it, you need to remove the shelf and unscrew the two screws securing the panel. Be careful - the backlight wires pass nearby.

If the thermostat is faulty, it must be replaced. For models Whirlpool original parts with article numbers W10196474, W10872825 or WPW10509886 are suitable (depending on the series). When replacing, be sure to unplug the refrigerator and discharge the capacitor!

4. Compressor breakdowns: when you can’t do without a repairman

The compressor is the “heart” of the refrigerator, which pumps refrigerant through the system. In Whirlpool inverter compressors are often installed (for example, in models WRX988SIBM), which are more reliable, but they can also fail.

Signs of a compressor malfunction:

• 🔇 The refrigerator does not hum at all (no sound running motor).
• 🔥 The compressor housing (the black “barrel” at the back of the refrigerator) gets very hot.
• ⚡ When turned on, protection is triggered (knocks out plugs or RCD).
• 🕒 The compressor works without stopping, but there is no cold.

The most common causes of compressor failure Whirlpool:

Repair yourself the compressor is not recommended - this is a complex and dangerous procedure that requires special equipment (vacuum pump, pressure gauges, refrigerant cylinder). In Whirlpool models with inverter compressors, attempting to charge freon yourself can lead to failure of the electronic control unit.

5. Clogged capillary tube and freon leak

The capillary tube is a thin channel through which the refrigerant enters the evaporator. In refrigerators Whirlpool it often becomes clogged due to moisture or small particles. This leads to the fact that freon does not circulate normally and the refrigerator stops freezing.

Signs of a clogged capillary tube:

• The compressor works without stopping.
• The condenser (grid at the back of the refrigerator) does not heat up.
• The freezer compartment does not freeze well, and the refrigerator compartment does not cool at all.

Freon leakage is another common problem. B Whirlpool leaks often occur at the soldering points of the tubes or due to corrosion of the evaporator. You can determine a leak by the following signs:

• 🛢️ Oily stains have appeared on the floor under the refrigerator (refrigerant mixed with oil).
• 🔍 Traces of corrosion are visible on the tubes (especially at the bottom of the refrigerator).
• 🌬️ The refrigerator is blowing warm air, even if the compressor is running.

To eliminate a blockage or leak, you need to:

1. Pump out the remaining freon.
2. Purge the system with nitrogen.
3. Remove the blockage or solder the leak.
4. Refill with new refrigerant ( Whirlpool usually freon is used R-134a or R-600a).

The compressor runs without stopping for more than 2 hours | The condenser is cold, although it should be warm | Frost or ice is visible on the tubes | The refrigerator does not freeze, but the light inside is on-->

It is not recommended to carry out this work yourself - errors during refilling can lead to failure of the compressor. The average cost of refilling freon Whirlpool is from 3,500 to 6,000 rubles (depending on the model and type of refrigerant).

6. Malfunctions of the electronic control unit

Refrigerators Whirlpool with electronic control (series 6th Sense, FreshControl) are equipped with complex circuit boards that can fail due to voltage surges, moisture or manufacturing defects. If the control unit is faulty, the refrigerator. can:

• 🔄 Turn on and turn off immediately.
• 🌡️ Do not respond to temperature changes.
• 📛 Give errors F8, F9 or E1.
• 🔇 Do not turn on compressor or fan.

The most vulnerable elements of the board are Whirlpool:

• 🔌 Compressor relay (contacts often burn).
• 🌡️ Temperature sensor drivers.
• 🔋 Capacitors (swell due to overheating).

How to check the control unit:

1. Unplug the refrigerator.
2. Remove the back cover (in most models the unit is located at the bottom, next to the compressor).
3. Inspect the board for blackened tracks, swollen capacitors or traces of oxidation.
4. Check the voltage at the output of the unit (should be 12-24 V depending on the model).

If you do not understand electronics, it is better to entrust the repair of the board to professionals. Service centers Whirlpool often offer not repair, but a complete replacement of the unit, which costs 8. 000–15,000 rubles. However, in some cases the board can be repaired (for example, replacing the capacitors or re-soldering the relay), which is 2-3 times cheaper.

7. Problems with the No Frost system: fan and evaporator

Refrigerators Whirlpool with the system No Frost (for example WRT311FZDW, WRX735SDHZ) have additional vulnerable elements: fan and evaporator. stops working, cold air does not circulate through the chambers, and the temperature rises.

Signs of a fan malfunction:

• 🔇 It has become quieter in the refrigerator (no characteristic air noise).
• ❄️ On the back wall of the freezer there is increasing ice.
• 🌬️ The refrigerator compartment does not cool, but the freezer is working normally.

To check the fan:

1. Unplug the refrigerator.
2. Remove the back panel in the freezer compartment (usually it is attached on latches or screws).
3. Try to turn the fan blades by hand. If they do not rotate or rotate with difficulty, the problem is in the bearings.
4. Check whether the evaporator is iced up (if ice is blocking the blades, it must be removed).

If the fan is not frozen. works, the reasons may be the following:

• 🔌 The fan motor is faulty (needs replacement, article number W10822776 for many models).
• 🧊 The blades are blocked by ice (you need to defrost the refrigerator).
• 🔌 Problems with power supply (check the wires and connectors).

In models Whirlpool with Dual Cooling (separate cooling of the chambers), the fan in only one of the chambers may fail. In this case, for example, the freezer works, but the refrigerator compartment does not.

8. When to call a technician: criteria and cost of repair

Not all breakdowns can be repaired yourself. Here are the cases when it is better to contact a service center:

• 🔧 refilling freon or soldering of pipes is required.
• 🔌 Faulty compressor or electronic unit.
• ⚡ Refrigerator electric shock or the RCD is triggered.
• 📛 The display shows errors F6, F8, E2 (related to electronic components).

Average prices for refrigerator repairs Whirlpool c 2026:

When choosing a service center, pay attention to the following points:

• 📋 Availability guarantees for work (minimum 6 months).
• 🔧 Use original spare parts (ask for articles).
• 🚚 Possibility home visit (in some cases the refrigerator cannot transport).

In some cases, repairs may be unprofitable. For example, if the compressor fails. refrigerator is older than 10 years, it is cheaper to buy new equipment. The average service life of refrigerators Whirlpool is 12–15 years.

Frequently asked questions

The Whirlpool refrigerator hums, but does not freeze. What is the reason?

If. the compressor hums, but the refrigerator does not cool, the following reasons are possible:

1. Freon leak —the compressor is running “idle.”
2. Clogged capillary tubes —the refrigerant does not circulate.
3. Malfunction of the switching valve (in models with two compressors).
4. Failure of the starting relay —the compressor cannot gain the required power.

It is difficult to diagnose the problem on your own - it is better to call a technician with a pressure gauge to check the pressure in the system.

Error F7 appears on the display of the Whirlpool refrigerator. What should I do?

Error F7 in refrigerators Whirlpool indicates a problem with freezer temperature sensor. Possible reasons:

• The sensor has failed (needs replacement, article number W10757896).
• The contacts on the board have oxidized controls.
• Problems with the wiring (the cable is frayed or broken).

Try to turn off the refrigerator for 10 minutes - sometimes this resets the error. If the error appears again, diagnostics are required.

Is it possible to fill freon into a Whirlpool refrigerator yourself?

No, refilling freon is a complex procedure that requires special equipment and skills. Errors during refueling can lead to:

• Damage to the compressor due to water hammer.
• Air entering the system, which will worsen cooling.
• Failure of valves or capillary tube.

In addition, modern refrigerators Whirlpool use refrigerant R-600a (isobutane), which is explosive if mishandled.

Whirlpool refrigerator freezes, but does not turn off. Is this normal?

No, the compressor must be turned off periodically (the operating cycle is usually 20-30 minutes of operation and 10-15 minutes of rest). If it works without stopping, the following problems are possible:

• Freon leak —the compressor is trying to compensate for the lack of refrigerant.
• Thermostat malfunction —it does not “see” the real temperature.
• Condenser contamination (grids at the back) - heat transfer is deteriorating.
• The temperature is set too low (for example, -24°C instead of -18°C).

Check whether the indicator light is on display error F3 or F5 - they often accompany this problem.

How much does it cost to replace a compressor in a Whirlpool refrigerator?

The cost of replacing a compressor depends on the model and type of compressor:

• Regular compressor (non-inverter): 8,000 - 12,000 ₽.
• Inverter compressor: 12 000 – 18 000 ₽.
• Compressor for Side-by-Side: 15 000 – 25 000 ₽.

The price includes:

• The compressor itself (original or analogue).
• Freon refilling.
• System diagnostics.

The service life of a new compressor is 10–15 years with proper operation.
