Does your refrigerator Ariston Hotpoint work around the clock, does not turn off and hums like a tractor? This is not just an annoying noise - it is a signal of a malfunction that can lead to compressor failure, frozen food or a spike in electricity bills. In 80% of cases, the problem is solved without calling a technician, if the cause is correctly diagnosed. But it is important to act quickly: continuous operation in 24/7 mode reduces the service life of equipment by 30-40%.
In this article we will analyze all possible reasons - from a banal clogged capillary tube to complex breakdowns of the electronic control unit. You will learn how to check the thermostat with a multimeter, why refrigerators Hotpoint-Ariston series HB i CBD more often suffer from freon leaks, and when exactly it’s time to call a specialist. And for models with the system Total No Frost we have prepared a separate diagnostic checklist.
Spoiler: in 6 out of 10 cases, it is not a broken compressor that is to blame, but violation of operating rules for example, installation close to the wall or overloading the freezer. But there are also insidious “invisible” breakdowns that cannot be determined without tools. Let's start with the simplest.
1. Checking the obvious: 5 reasons that 90% of users miss
Before disassembling the refrigerator or calling the service center, exclude these basic factors. They do not require repairs, but it is because of them that the equipment often works without stopping.
- 🔌 Super Freeze mode or "Quick cooling" is activated. In models Ariston Hotpoint it may turn on accidentally when you press the display or touch the button with products. Check the indicators on the panel - if the icon
SUPERor the snowflake ❄️ is on, turn off the mode manually. - 🌡️ The room temperature is above 30°C. Refrigerators Hotpoint with climate class
SN-T(most models) are designed to operate up to +32°C, but the compressor will turn on more often. If in the summer the appliances are in the kitchen without air conditioning, this is normal - but not optimal. - 🚪 The door is not closed tightly. Even a micro gap of 1-2 mm makes the refrigerator work without interruption. Check the seal: if it is dirty or deformed, replace it (part number for Ariston —
C00368966). - 🍖 Overload with food. Full shelves block air circulation, especially in models with No Frost. Unload the chambers by 30% and check if the operating mode changes after 6-8 hours.
- ☀️ Direct sunlight or heat from the stove. If the refrigerator is located next to the oven or under a window, its sensors detect false “warming” and force the compressor to work longer.
If none of the points apply, go to deep diagnostics. But first answer the question:
2. Thermostat: how to check and replace it yourself
The thermostat (or thermostat) is the “brain” of the refrigerator, which sends a signal to the compressor to turn on/off. In models Ariston Hotpoint it often fails due to power surges or natural wear and tear. malfunctions:
- ❄️ The compressor works continuously, but in the fridge compartment too cold (products freeze slightly).
- 🔥 The compressor does not turn off, but in the chamber heat (the thermostat "does not see" the real temperature).
- 🔄 The refrigerator turns off, but after 5-10 minutes it turns on again (false sensor signals).
To check the thermostat, you will need a multimeter:
- Unplug the refrigerator and remove the protective cover from the thermostat (usually located next to the light bulb).
- Disconnect the wires from the terminals. In models Hotpoint this is usually
3or4contact. data-i="99">Switch the multimeter to resistance testing mode (ohmmeter) and measure the resistance between the terminals - Set the multimeter to resistance test mode (ohmmeter) and measure the resistance between the terminals
3 and 4(or1 and 2- see the diagram on the thermostat body). - Turn the thermostat knob (if it is mechanical). If the sensor is working, the resistance should change smoothly from
0to∞.
If the resistance does not change or is equal to 0/∞ in any position, the thermostat is faulty. data-i="108">original spare parts are suitable: Ariston Hotpoint Original spare parts are suitable:

Replacing the thermostat takes 15-20 minutes. The main thing is not to mix up the wires. connection. If you are not confident in your abilities, contact the service. But remember:
3. data-i="116">In models
Leakage of refrigerant (freon) is the most dangerous reason for the continuous operation of the refrigerator. Without freon, the compressor runs “idle”, overheats and can burn out. 1-2 days. In models Ariston Hotpoint leakage often occurs in places where pipes are soldered or due to corrosion of the circuit. Signs:
- ⏳ The compressor works more than 20 minutes without stopping, but there is no cold in the chamber.
- 🧊 Condenser (grid at the back of the refrigerator) does not heat up (normally it should be warm).
- 💧 Appears on the floor under the refrigerator oily puddle (freon is mixed with compressor oil).
You cannot fix the leak yourself - you need special equipment for vacuuming and refilling. But you can prevent compressor breakdownif you turn off the refrigerator in time and call a technician:
- Leak diagnostics:
1 000–1 500 ₽. - Refilling with freon (R134a or R600a):
2 500–4 000 ₽. - Replacing the evaporator (in case of severe corrosion):
5 000–8 000 ₽.
Attention: if the leak occurred in the freezer, do not try to defrost refrigerator! This can accelerate the corrosion of the tubes. It is better to immediately disconnect it from the network and leave the doors open for ventilation.
What will happen if you ignore the leak of freon?
The compressor will overheat and fail - replacing it will cost 70-80% of the cost of a new refrigerator. cause dizziness and nausea if inhaled in a closed room.
4. Compressor failure: symptoms and solutions
The compressor is the “heart” of the refrigerator, and its malfunction often leads to continuous operation in models Ariston Hotpoint compressors. data-i="140">or Embraco or Secop serve on average 10-15 years, but may fail earlier due to:
- ⚡ Voltage surges (especially important for houses with old wiring).
- 🔥 Overheating due to a clogged capacitor.
- 🛠️ Incorrect refilling of freon after repair.
How to check the compressor:
- Unplug the refrigerator and wait 10 minutes.
- Remove the back cover (in most models Hotpoint it is secured with 4-6 screws).
- Find the compressor - it’s a black “barrel” with tubes. Turn on the refrigerator and listen:
| Compressor sound | What does this mean | Solution |
|---|---|---|
| Loud humming, but no vibration | The piston is stuck or burned out winding | Replacing the compressor (6 000–12 000 ₽) |
| Clicks every 5-10 seconds | The start-up relay is activated | Checking the relay or replacing the compressor |
| Quiet buzzing, but no cold | Freon leak or clogged capillary tube | Diagnostics of the cooling system |
If the compressor is hot to the touch and does not turn off for more than 30 minutes, immediately disconnect the refrigerator from the network. Further operation may lead to a fire!
5. Clogged capillary tube: how to clean it without a technician
The capillary tube is a thin channel through which freon enters the evaporator. Ariston Hotpoint it often becomes clogged due to:
- 🔧 Remains of oil after poor-quality freon refilling.
- 🧊 Formation of an ice plug (in models with No Frost).
- 🛢️ Moisture entering the system (during depressurization).
Symptoms blockage:
- The compressor works without stopping, but the freezer compartment frozenand the refrigerator compartment is warm.
- Condenser (grid at the back) hot in only one part.
- After turning off the refrigerator for 10-12 hours, the problem does not disappear.
To clean the capillary tube you will need:
- Turn off the refrigerator and defrost it for 24 hours.
- Remove the back panel and find the capillary tube (a thin copper tube running from the condenser to the evaporator).
- Gently tap it with a wooden stick (not metal!) to remove the ice plug.
- If the blockage is hard (oil, dirt), you will need purging with nitrogen —this is done only in service centers.
Attention: do not try to clean the tube with a wire or a needle! This may damage its walls and lead to freon leakage.

6. Problems with the electronic control unit
In modern models Ariston Hotpoint (for example, series HF or BAA) the electronic control unit (ECU) is responsible for the operating mode. Its breakdown can lead to:
- 🤖 Continuous operation of the compressor due to false sensor signals.
- 📛 Errors on the display (codes
F01,F05,F11). - 🔄 Spontaneous turning on modes
Super CoolorHoliday.
How to diagnose the problem:
- Turn off the refrigerator for 10 minutes, then turn it on again. If the problem disappears, it was a firmware failure.
- Check the error codes on the display (see the instructions for decoding). model).
- If the refrigerator does not respond to buttons or shows inadequate temperatures (for example,
-30°Cin the refrigerator compartment), the ECU is faulty.
ECU repair cost:
- Reflashing:
1 500–2 500 ₽. - Replacing the unit:
4 000–7 000 ₽(depending on the model).
Attention: if your refrigerator is under warranty, do not try to repair the ECU yourself! This will lead to loss of warranty.
How to reset errors on the display Ariston Hotpoint?
Press and hold the buttons Super Cool + Holiday for 10 seconds. If the error remains, diagnostics of the master is required.
7. Temperature sensors: why they lie
In refrigerators Ariston Hotpoint with electronic control (series HF, BAA, CBD) sensors NTC or PTCare responsible for the temperature. Their malfunction leads to the compressor receiving incorrect data and running without stopping. Signs:
- 🌡️ Temperature on the display does not correspond to the real one (for example, shows
+5°C, but in the chamber0°C). - 🔄 The compressor turns on too often (every 5-10 minutes).
- ❄️ In the freezer is formed snow coat", switched on No Frost.
How to check the sensor:
- Turn off the refrigerator and find the sensor (usually it is located behind the back wall of the refrigerator compartment, next to the evaporator).
- Disconnect the connector and measure the resistance with a multimeter. At room temperature (
+20°C) it should be:
- For the sensor NTC:
4.7–5.3 kOhm. - For the sensor PTC:
1.8–2.2 kOhm.
If the resistance is equal to 0 or ∞, its replacement will cost 800–1 500 ₽ (depending on the model).
8. When to call a technician: 3 critical cases
Some breakdowns cannot be repaired yourself. Contact the service center if:
- Freon leak - the system needs to be vacuumed and charged.
- The compressor burned out - it replacement requires special equipment.
- Failure of the electronic unit —without diagnostics at the stand it is impossible to determine the exact cause.
