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

The refrigerator Whirlpool is a reliable assistant in the kitchen, but even the highest quality equipment can fail. One of the most common problems that owners face: the unit does not turn offworks around the clock, consumes electricity at an increased rate, and the products are either frozen or not cooled enough. If your refrigerator VIRPOOL (this is how the brand is sometimes mistakenly written) hums without interruption, do not rush to call a repairman - in half of the cases the cause can be eliminated yourself.

In this article we will examine all possible causeswhy the refrigerator Whirlpool does not turn off: from trivial (incorrect temperature setting) to serious (refrigerant leak). You will learn how to carry out primary diagnostics, which components to check first, and in which cases you cannot do without professional repairs. We will also give step-by-step instructions for troubleshooting problems that do not require special tools.

⚠️ Attention! If the refrigerator Whirlpool not only does not turn off, but also makes uncharacteristic sounds (knocking, grinding, hissing), turn it off immediately it from the network. This may indicate critical compressor malfunction or freon leak - further operation is dangerous!

1. Incorrect temperature settings

The first thing to check is refrigerator operating mode. Often the problem lies in accidentally changed settings or activated additional functions. In models Whirlpool (for example, WRB322DMBB, WRT311FZDW), the temperature range is usually adjusted manually or via an electronic panel.

If the refrigerator works without stopping, but freezes too much, the mode may be set super freeze (Super Freeze) or intensive cooling (Fast Cool). These functions are designed to quickly lower the temperature, but if they are not turned off, the compressor will run continuously.

• 🔹 Check the current mode on the display (if available). The snowflake icon or inscription Super indicates the activated function.
• 🔹 In mechanical models (with a rotary control), set the knob to position 2-3 (average value).
• 🔹 In electronic refrigerators, go to the menu and reset the settings to factory settings (Reset).

If, after resetting the settings, the refrigerator Whirlpool still does not turn off, proceed to the next steps.

2. Problems with the thermostat or temperature sensor

The thermostat (or thermostat) is key elementthat controls the operation of the compressor. If it fails, the refrigerator Whirlpool "does not understand" when to turn off and works without interruption. Modern models use electronic sensors instead of a mechanical thermostat, but the principle of operation remains the same.

How to check the thermostat:

1. Unplug the refrigerator and defrost it (if there is one). ice on the walls).
2. Find the thermostat - in most models Whirlpool it is located inside the chamber, under the plastic panel.
3. Remove the protective casing and inspect the contacts. If there are signs of oxidation or burning, the part must be replaced.
4. For accurate diagnosis, use. multimeter: at room temperature, the thermostat contacts must be closed.

⚠️ Attention! In refrigerators Whirlpool with a system No Frost the thermostat can be integrated into the electronic control unit in this case, independent replacement is not recommended - flashing the module is required.

3. Freon leak or clogged capillary tube

If The refrigerator Whirlpool does not turn off, but cools poorly.the problem may lie in refrigerant leak (freon) or clogged capillary tube. These faults require professional repair, but they can be diagnosed independently.

Signs of a freon leak:

• 🔍 The compressor runs non-stop, but the chambers are warm.
• 🔍 There is no condensation on the back wall of the refrigerator (normally it should appear during prolonged periods work).
• 🔍 There may be traces of oil at the leak site (usually on the circuit tubes).

A clogged capillary tube manifests itself with similar symptoms, but most often this happens after incorrect refilling of freon or moisture entering the system. In both cases, you will need:

1. Evacuation. system.
2. Replacing the filter-drier.
3. Recharging with new refrigerant (in models Whirlpool usually used R134a or R600a).

What happens if you ignore a freon leak?

Prolonged operation of the compressor without refrigerant leads to its overheating and failure. In some cases, this can cause a fire due to a short circuit in the motor winding.

4. Compressor malfunction

The compressor is the “heart” of the refrigerator. If it works without stopping, this does not always mean it is broken. However, there are signs that indicate a motor malfunction:

• 🔧 The compressor gets very hot (it burns your hand when touched).
• 🔧 Uncharacteristic noise appears: knocking, grinding, hum.
• 🔧 On traces of oil are visible on the compressor housing (leakage through the oil seal).

The most common problems with the compressor in refrigerators Whirlpool:

1. Interturn short circuit —the motor windings short-circuit to each other, which leads to overheating.
2. Wear of the piston group — the compressor works, but does not create the required pressure.
3. Shaft jamming —the motor hums, but does not start (replacement is required).

⚠️ Attention! If the compressor refrigerator Whirlpool turns off 1-2 seconds after starting and turns on again, this is a sign faulty start-up relayReplacing it will cost less than repairing the motor.

5. Problems with the door seal

If the sealing rubber is on the refrigerator door Whirlpool worn out or dirty, warm air constantly enters the chamber. The compressor is forced to work without stopping to compensate for the loss of cold. This problem is especially relevant for older models (for example, Whirlpool ARC 4200), where the rubber loses its elasticity over time.

How to check the seal:

1. Close the door and try to insert a sheet of paper between it and the body. If it passes easily, the seal is leaking.
2. Inspect the rubber for cracks, tears or deformations.
3. Check for traces of mold or sticky deposits on the seal (they can be cleaned with soapy water).

If the seal damaged, it needs to be replaced. In models Whirlpool it is attached either with self-tapping screws or with special latches. The number of the original part can be found in the instructions or on the manufacturer’s website for the refrigerator model.

6. Malfunction of the electronic control unit

In modern refrigerators Whirlpool (for example, WRX735SDHZ, WRF535SWHZ) the electronic module is responsible for the operation of the compressor. If it fails, various failures may occur, including continuous operation of the motor. Frequent reasons:

• 🔌 Power surges in the network.
• 🔌 Moisture on the board.
• 🔌 Short circuit in the sensor circuit.

Signs of a faulty electronic unit:

• 📛 Errors appear on the display (E1, F5, PF).
• 📛 The refrigerator turns on/off spontaneously.
• 📛 Does not respond to button presses.

Independent repair of the board is possible only if you have experience working with electronics. In most cases, the following is required:

1. Reflashing the microcontroller.
2. Replacement of burnt elements (resistors, transistors).
3. Soldering of damaged ones tracks.

⚠️ Attention! If the refrigerator Whirlpool is connected through a surge protector or stabilizer, but the problem persists, check the socket. Low voltage (less than 200V) may cause malfunctions of the electronic unit.

7. No Frost systems

Refrigerators Whirlpool with a system No Frost (for example, WRF560SMYM, WRX988SIBM) require regular maintenance. If the fan or evaporator becomes clogged with ice or dust, air circulation is disrupted and the compressor is forced to work non-stop to maintain. temperature.

How to clean the system No Frost:

1. Disconnect the refrigerator and defrost it (at least 12 hours).
2. Remove the back panel in the freezer (usually it is secured with latches).
3. Clean the fan and evaporator from ice and dirt using a soft brush.
4. Check the drainage hole - if it is clogged, water will accumulate and freeze.

FAQ: Frequent questions about the continuous operation of the Whirlpool refrigerator

My Whirlpool refrigerator works without stopping, but it freezes normally. What's wrong?

Most likely the problem is thermostat or temperature sensorThe compressor does not receive a signal that the desired temperature has been reached and continues to work. Check the settings. and inspect the contacts of the thermostat. If everything is in order, the sensor needs to be replaced.

The Whirlpool refrigerator does not turn off and gets very hot on the sides. What should I do?

This is normal - the sides. the walls of the refrigerator heat up due to the operation of the condenser. However, if the heating is excessive (burns your hand), check ventilation (the distance to the wall should be at least 5 cm) and cleanliness of the condenser (dust impairs heat transfer).

After defrosting, the Whirlpool refrigerator does not turn off. Why?

Probably moisture got into the system, which led to clogging of the capillary tube or icing of the evaporatorTry to defrost the refrigerator again (on 24 hours) and dry it. If the problem persists, contact the service.

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

Theoretically yes, but in practice this requires special equipment (vacuum pump, pressure manifold) and skills. An error during refueling can lead to damage to the compressor or leakage. refrigerant. It is better to entrust this to professionals.

The Whirlpool refrigerator is new, but it does not turn off from the first day. What is wrong?

It may be defective compressor or incorrect setting at the factoryYou need to contact the service center under warranty. Do not try to repair it yourself - this may void. warranty.
