The situation when a loved one Whirlpool ceases to perform its main function always takes you by surprise. The food begins to deteriorate, a puddle appears on the shelves, and the inside of the chamber is unbearably stuffy. Why doesn't the refrigerator freeze Whirlpool? This issue becomes critical in the very first minutes of detection of a malfunction. Often the cause is a simple violation of operating rules or an electronics failure, rather than a fatal breakdown of the unit.
Modern brand models are equipped with a complex system No Frost or combined cooling, which requires a competent approach to diagnostics. Owners of two-chamber models Whirlpool 6th sense often encounter the fact that the freezer is working normally, but the refrigerator compartment is warm. And vice versa. Understanding the operating principles of your specific model will help you quickly find the root of the problem.
Do not panic and immediately call a technician if you have just defrosted the device or loaded a lot of warm food into it. The system might simply not have time to reach operating mode. However, if the problem persists for more than a day, it is necessary to conduct a thorough check of all components.
Checking the thermostat and temperature settings
First of all, the human factor should be eliminated. Perhaps one of the household members accidentally touched the regulator or the settings in the electronic control unit were lost. In models with mechanical control, the control is controlled by thermostat, which can be shifted to the "minimum" position.
If you have a model with an electronic display, check whether the "vacation" or "demo mode" mode is activated. In this state, the compressor may not start at all or may operate with long interruptions. To reset the settings, try unplugging the appliance for 10-15 minutes.
How to correctly set the temperature in Whirlpool?
For most models, the optimal temperature in the refrigerator is +4...+5°C, and in the freezer -18°C. Do not set minimum values unless necessary - this increases compressor wear.
Pay attention to the location of the temperature sensors. In some modifications they are located on the back wall and can be covered with food. If the sensor “sees” the cold from a jar of jam lying nearby, it will not give the command to start the engine.
Problems with the No Frost defrosting system
Technology No Frost greatly simplifies the maintenance of equipment, but adds complex components that can fail. If the refrigerator Whirlpool has stopped freezing, and a layer of ice or snow is visible on the back wall, it means that the water drainage or evaporator defrosting system is not working.
The main culprits here are:
- ❄️ Defrost heating element — a heating element that could have burned out and stopped melting the ice on evaporator.
- ❄️ Defrost timer —a mechanism that is “stuck” in the cooling mode and does not switch the system to defrosting.
- ❄️ Drainage hole —a banal blockage, due to which the melt water does not drain, freezes and blocks air circulation.
☑️ Diagnostics of the No Frost system
In models Whirlpool with a system 6th sense an electronic module is often responsible for the defrosting process. If it receives incorrect data from sensors, the cycle may be disrupted. Ice plugs in air ducts are a common reason why cold air simply does not reach food.
⚠️ Attention: If you find ice freezing, do not try to knock it off with a knife or sharp objects. Damage to the evaporator will lead to freon leakage and expensive repairs.
Faults in the compressor and start relay
The heart of any refrigerator is the compressor. If you hear the engine humming, but there is no cold, or it clicks and immediately turns off, the problem is in the starter mechanism. In older models Whirlpool the start-up relay often fails.
Modern inverter compressors are more reliable, but are sensitive to voltage drops. If the relay is stuck or burned out, the motor windings do not receive the impulse to start. Replacing this part is one of the most frequent and inexpensive procedures in the service.
If the compressor operates continuously, but the temperature does not drop, the pump itself may fail (loss of performance) or the circuit may fail. Only a technician with a pressure gauge station can check the pressure in the system.
Leak of refrigerant (freon)
One of the most unpleasant reasons why it does not freeze Whirlpoolis a leak freon. The refrigerant circulates in a closed circuit, and if a microcrack appears in the tubes, the gas escapes. Without a sufficient amount of freon, heat exchange is impossible.
Signs of a leak:
- 🌡️ The compressor works non-stop, trying to gain temperature.
- 🌡️ The condenser grille at the rear remains cold or barely warm.
- 🌡️ In the freezer, a “fur coat” appears only at the entrance of the tubes or in one corner.
Often leaks occur in places of factory soldering or due to metal corrosion (especially in models with a foamed evaporator). It is impossible to find the leak location on your own; special equipment is required for pressure testing and searching.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Ice only at the entrance of the tubes | Leakage freon | High |
| Compressor does not start | Relay or thermostat malfunction | Low |
| Noise and vibration | Problems with the fan or compressor | Medium |
| Water on the floor | Drainage clogged or defrosting | Low |
Clogged capillary tube
The capillary tube is the thinnest channel through which the refrigerant enters the evaporator. Over time, oil oxidation products or moisture can accumulate in the system and form a plug. The circulation of freon stops and the refrigerator stops cooling.
The blockage can be identified by a characteristic sign: the compressor is running, the condenser is hot, but it is warm inside. In this case, the tube before entering the evaporator may be cold, and after it - warm, which indicates a stop in flow.
To eliminate the malfunction, it is necessary to evacuate the system, flush with nitrogen and replace the filter-drier. This is a complex technical procedure that requires qualifications and special tools.
Failures in the operation of the electronic control module
In models Whirlpool with electronic control, all processes are coordinated by the main module. Voltage surges in the network, moisture or manufacturing defects can lead to burning of board elements. As a result, the “brains” of the refrigerator stop sending the correct commands to the actuators.
Symptoms of module failure:
- 🔌 The indicators on the panel blink or light up chaotically.
- 🔌 The refrigerator does not respond to pressing buttons.
- 🔌 Arbitrary switching on and off of the compressor.
⚠️ Attention: Repairing the electronic board is often impractical. In most cases, a complete replacement of the control module with an original or high-quality analogue is required.
Sometimes the problem is solved by flashing it or simply resetting errors, but diagnostics must be carried out by a specialist. Do not try to disassemble the board yourself if you do not have experience working with microelectronics.
When you need to call a specialist
Independent repair is possible only in cases of simple malfunctions: replacing a light bulb, cleaning the drain, replacing the thermostat in available models. If the problem lies in the sealed circuit, compressor or electronics, it is better to trust the professionals.
Contacting service is necessary if:
- You hear the smell of burnt wiring.
- The compressor gets very hot and does not turn off.
- A freon leak has been detected in the system.
- The compressor needs to be replaced or pipes soldered.
Remember that timely repairs are cheaper than buying a new unit or restoring damaged products. Professional diagnostics will take less time than a long search for the cause at random.
Why does a Whirlpool refrigerator freeze but does not turn off?
This may indicate a freon leak, compressor wear, or a violation of the thermal insulation of the housing. Also check the tightness of the door.
How often do you need to defrost Whirlpool No Frost?
No Frost systems do not require regular defrosting. However, once a year it is recommended to carry out preventive defrosting for 24 hours for hygiene and checking drainage.
Can I use a Whirlpool refrigerator if it hums quietly?
A quiet hum is normal operation of the compressor. You should worry if there are knocking sounds, a grinding noise or a hum that becomes very loud.
What to do if there is water in the refrigerator compartment and ice in the freezer?
Most likely, the drainage hole is clogged. Try cleaning it with a soft wire or warm water. If it doesn’t help, the problem is in the defrost system.
How long does the compressor last in a Whirlpool refrigerator?
The average service life of a compressor is 10-15 years with proper operation. Inverter models can work longer thanks to a soft start.
