The freezer in the Ariston refrigerator does not work: reasons and what to do

If the freezer compartment in your refrigerator Ariston stops working, but the refrigerator compartment is functioning normally, this is an alarming signal. This problem can lead not only to food spoilage, but also to serious damage to the compressor or electronics. In 80% of cases, the malfunction is associated with clogging of the capillary tube, failure of the thermostat or problems in the system No Frost (if your model has it).

It is important to understand: refrigerators Ariston (especially models Hotpoint-Ariston and series MBF, MBA) have a specific evaporator design and refrigerant circulation system. For example, in two-compressor models, a freezer may fail due to breakdown separate motor-compressor, while in single-compressor models it often becomes solenoid valve. We will analyze all possible causes - from banal icing to complex electrical malfunctions.

Before starting repairs, check the obvious: whether the power is turned off, whether the freezer is overloaded with food (this blocks air circulation), whether the mode Super Cool or Holidayis set, which turns off the freezer. If everything is in order, read on.

1. Typical signs of a freezer malfunction

The first thing to do is diagnose symptoms. The freezer may “not work” in different ways:

• 🔴 Complete absence of cold —the temperature in the chamber is equal to room temperature, the compressor does not turn on or works without stopping.
• ❄️ Weak cooling —food thaws, but does not defrost completely; frost forms on the walls.
• 💨 Continuous operation of the fan (in models with No Frost) - noise is heard, but the cold does not accumulate.
• 🔥 The compressor overheats — the case is hot, thermal protection is triggered (the refrigerator turns off spontaneously).
• ⚡ Electronic errors —codes appear on the display F05, F08, F11 (see explanation below).

If the freezer Ariston does not freeze, but the refrigerator compartment is workingthe problem lies in one of three components:

1. Circulation system refrigerant (freon leak, capillary tube clogged).
2. Electronics (thermostat, control board, temperature sensors).
3. Mechanical components (No Frost fan, magnetic valve, door seal).

Critical moment: if the compressor runs without stopping for more than 2 hours and the freezer is not cooling, immediately unplug the refrigerator! This can lead to overheating of the windings and complete failure of the motor.

2. The most common causes of freezer failure

Let's look at TOP-5 malfunctionthat lead to freezer failure in refrigerators Ariston (data based on statistics from service centers for 2023–2026).

In models Ariston Hotpoint with system Total No Frost (for example, HBM 13221, HBM 1182) most often fails defrost timer or Evaporator heating element. These parts are responsible for automatic defrosting and, if broken, lead to icing of the air circulation channels.

How to check if the No Frost fan is working?

Open the freezer door and listen. In normal mode, the fan should turn on after 1–2 minutes (light air noise). If you can't hear it, but the compressor is running, the fan is most likely blocked by ice or broken. In models Ariston it is located behind the rear panel of the freezer (you will have to remove the cover).

3. Diagnostics: how to find the cause yourself

Before disassembling the refrigerator, perform preliminary diagnostics:

🔌 Make sure that the refrigerator is connected to the network (check the socket with a multimeter)

❄️ Inspect the door seal for cracks or deformations

📱 Check the error codes on the display (if any)

👂 Listen to the operation of the compressor (should turn on/off with pauses)

🧊 Check if the products are blocking air circulation in the freezer -->

If no external problems are found, proceed to deep diagnostics:

Checking the compressor

The compressor in refrigerators Ariston is usually located at the bottom of the back wall. When the motor is running:

• 🔊 A uniform hum should be heard (no grinding or knocking!).
• 🔥 The compressor housing should heat up (but not burn!).
• ⚡ If the motor does not turn on at all, the problem is start relay, thermal protection or winding breakage.

To check the compressor with a multimeter:

1. Disconnect the refrigerator from network.
2. Remove the starting relay (attached to the compressor).
3. Measure the resistance between the contacts:
   • Common point (C) → Starting (S): ~20–40 Ohm.
   • Common point (C) → Running (R): ~10–20 Ohm.
   • S → R: the sum of the two previous values (for example, 30 + 15 = 45 Ohm).

If the resistance is equal 0 (short circuit) or ∞ (open) - the compressor is faulty.

Checking the thermostat and sensors

In refrigerators Ariston two types of temperature controllers are used:

• 🔘 Mechanical thermostat (in older models, for example, Ariston MG 185).
• 📱 Electronic sensor (in modern ones, for example, Ariston HBM 1182).

To check the mechanical thermostat:

1. Remove the temperature control knob.
2. Disconnect the terminals and connect them together (with a jumper).
3. If the compressor starts, the thermostat is faulty.

Electronic sensors are checked with a multimeter:

• Resistance of a working sensor at room temperature: ~5–7 kOhm.
• When cooling (for example, with ice), the resistance should drop.

⚠️ Attention! In models with electronic control (Ariston HBM 13221, HBM 1182), when replacing the sensor, it may be necessary reflashing the boardIndependent replacement without experience is fraught with errors E03 or F11.

4. Freon leak and capillary tube clogged

If the compressor is working, but the freezer is not cooling, and the condenser (grid) on the back wall) remains cold - this 100% sign of a freon leak or a blockage in the system.

How to determine a freon leak

Symptoms:

• 🔊 The compressor turns on for 5-10 seconds and turns off (protection is triggered).
• 🧊 There is no frost on the evaporator tubes (in normal condition there should be).
• 🔥 The condenser does not heats up.

Repair the leak yourself impossible - required:

1. Detect the location of the leak (most often it is soldered connections or aluminum evaporator).
2. Eliminate damage (soldering, tube replacement).
3. Evacuate the system and charge with freon (usually used Ariston usually used R134a or R600a).

In 60% of cases, a leak occurs in the evaporator of the freezer due to corrosion of aluminum. In such cases, a complete replacement of the evaporator is required, which costs 8,000–15,000 rubles.

Clogged capillary tube

The capillary tube is a thin channel through which freon enters the evaporator. When clogged (for example, with particles of oil or moisture) the refrigerant does not circulateand the freezer stops working.

Symptoms blockage:

• 🔄 The compressor works non-stop, but the freezer does not cool.
• 🧊 The condenser is hot only at the beginning, then it cools down.
• 🔧 If you touch the capillary tube (thin copper tube in front of the evaporator), it will cold.

To remove the blockage, the master:

1. Cuts off the filter drier and capillary tube.
2. Blows the system with nitrogen under pressure.
3. Installs a new filter drier and seals the tube.
4. Evacuates and charges with freon.

⚠️ Attention! Do not try to clean the capillary tube yourself - without special equipment you risk damaging the system. Ariston the tubes are often soldered to the evaporator, and their replacement requires complete disassembly of the freezer.

5. Problems with the No Frost system

If your refrigerator Ariston is equipped with a system No Frost (models HBM, MBA, RSTA), then the freezer failure may be due to c:

• 🔄 Fan malfunction —cold air does not blow.
• ❄️ Icing of the evaporator —the fan is blocked by ice.
• 🔥 Failure of the defrost heating element —the evaporator does not defrosts.
• ⏱️ Failure of the defrost timer —the defrosting cycle does not start.

For diagnostics:

1. Turn off the refrigerator and defrost it for 12–24 hours.
2. After turning it on, listen - if the fan does not start, check:
• Is it blocked by ice (you need to remove the back panel of the freezer).
• The serviceability of the fan motor (check the windings with a multimeter).

If the fan works, but the freezer does not cool, the problem is in defrost sensor or Heating element.

In models Ariston Hotpoint with Full No Frost (for example, HBM 13221) most often fails heating element fuse (costs 200–300 RUR). defrosting, the freezer started working, but after 1-2 weeks the problem returned - the defrosting heating element or the timer is to blame. In this case, defrosting helps temporarily, but the breakdown will remain.

6. Solenoid valve in single-compressor models

In refrigerators Ariston s one compressor (for example, Ariston MBA 2200, MBA 1800) is responsible for the distribution of cold between the chambers. If it breaks down, the refrigerator compartment works, but the freezer does not (or vice versa). electromagnetic valve. If it breaks, the refrigerator compartment works, but the freezer does not (or vice versa).

Signs of valve malfunction:

• 🔊 When switching modes, clicks are heard, but cold does not enter the freezer.
• 🧊 The refrigerator compartment freezes, but the freezer does not cool.
• ⚡ An error may appear on the display F08.

How to check the valve:

1. Unplug the refrigerator.
2. Find the valve (usually located on the tube behind the compressor, has a connector with 2-3 wires).
3. Test the valve winding with a multimeter - the resistance should be ~1–3 kOhm.
4. If the resistance is 0 or ∞ the valve is faulty.

Replacing the valve costs 1,500–3 000 ₽ (part) + 2,000–4,000 ₽ (work). In some models Ariston the valve is soldered into the system, and its replacement requires refilling the freon.

7. Ariston freezer error codes

Modern. refrigerators Ariston (series HBM, MBA, RSTA) are equipped with electronic controls and display error codes on the display. If the freezer does not work, pay attention to the following codes:

If an error appears on the display, first try reset it:

1. Disconnect the refrigerator from the mains for 5–10 minutes.
2. Turn it back on and wait 30 minutes.
3. If the error appears again, diagnostics is required.

⚠️ Attention! In refrigerators Ariston with a display (for example, HBM 13221), resetting errors through the menu can lead to reset all settings. To avoid this, use only a physical power shutdown.

8. When to call a technician, and when you can handle it yourself

Not all freezer breakdowns Ariston require professional repairs. data-i="307">what you can do yourself what you can do yourself:

• ✅ Defrosting - if the problem is No Frost icing.
• ✅ Replacing the door seal - if it is torn or deformed.
• ✅ Cleaning the condenser - dust on the grill worsens heat exchange.
• ✅ Replacing the light bulb - if the freezer is not lit, but there is cold.
• ✅ Checking thermostat/sensor (if you have the skills to work with a multimeter).

In what cases is a technician needed:

• ❌ Freon leakage (evacuation and refilling required).
• ❌ Capillary tube clogged (special equipment required).
• ❌ Replacement compressor or solenoid valve.
• ❌ Repair of the control board (soldering iron and experience required).
• ❌ Replacement of the evaporator (in models with No Frost).

Average cost of repairing a freezer Ariston in service centers:

• 🔧 Diagnostics: 1,000–1,500 ₽.
• 🛠️ Replacement of thermostat/sensor: 2,000–3,500 ₽.
• ❄️ Elimination of leaks freon + refill: 5,000–10,000 ₽.
• 🔄 Compressor replacement: 6,000–12,000 ₽.
• 📱 Repair of control board: 3,000–8,000 ₽.

⚠️ Attention! If your refrigerator Ariston under warranty - do not disassemble it yourself! Opening the seals will result in loss of warranty. Contact an authorized service center (the list can be found on the website Ariston by model number).

FAQ: Frequently asked questions about the Ariston freezer

The freezer does not freeze, but the refrigerator works - what to do first queue?

First check:

1. Is the mode Holiday or Super Cool (turns off the freezer).
2. Are the products blocking the air circulation (in models with No. Frost).
3. Serviceability of the door seal (if it is torn, replace it).
4. Error codes on the display (if any).

If everything is in order, turn off the refrigerator for 12 hours to completely defrost. If after turning on the problem remains, look for a deeper cause (thermostat, valve, freon leak).

How can you tell that there is a freon leak in an Ariston freezer?

Signs of a leak:

• The compressor turns on for 5-10 seconds and turns off.
• The condenser (grid at the back) does not heat up.
• The freezer evaporator tube is not covered with frost.
• If you touch the compressor, it is cold (normally it should heat up).

You cannot fix the leak yourself - you need a technician with equipment for vacuuming and filling.

Is it possible to replace the thermostat in Ariston yourself?

Yes, if you have a mechanical thermostat (in older models). To do this:

1. Disconnect the refrigerator from the mains.
2. Remove the temperature control knob.
3. Disconnect the thermostat terminals and remove it from the housing.
4. Install a new thermostat (suitable for your model, for example, K59-L1938 for Ariston MBA).
5. Connect the terminals and check the operation.

In models with electronic control (Ariston HBM), the thermostat is replaced along with the board or sensor - here it is better to call a technician.

Why Ariston freezer works, but does not turn off?

Possible reasons:

• 🔄 The thermostat has failed —does not give a command to turn off.
• 🧊 Freon leak —the compressor tries to gain temperature, but cannot.
• 🔥 Capillary tube clogged —freon does not circulate.
• 📱 Control board failure (in electronic models).

First defrost the refrigerator for 12 hours. If after turning on the compressor works again without stopping, call a technician.
