Why does the Ariston Hotpoint refrigerator make noise: normal or broken?

Did your refrigerator Ariston Hotpoint suddenly begin to hum loudly, crackle or vibrate? Don’t rush to panic - in 70% of cases it’s not a breakdown, but the peculiarities of the equipment’s operation. But how can you distinguish normal noise from a malfunction signal? In this article we will examine 8 main causes of hum the models Hotpoint-Ariston (including popular series HB 3800, HBM 1201, CBA 3300), explain when you can handle it yourself, and when you need a master. You will also find step-by-step diagnostic instructionsa table of characteristic sounds and answers to frequently asked questions from owners.

Important to understand: modern refrigerators Ariston equipped with inverter compressors and a system No Frostthat are quieter than older models, but still make sounds. For example, cyclic switching on of the compressor (every 10–20 minutes) or refrigerant flow through the pipes is the norm. But constant high-frequency whistle or metallic grinding is a cause for concern. Next, we will teach you to distinguish one from the other.

1. Normal operating sounds of an Ariston Hotpoint refrigerator

Before committing a breakdown, make sure that the noise is not the standard operating sounds of the appliance. The manufacturer Ariston in the instructions for the models (for example, HBM 1182 or CBA 3200) directly indicates that the refrigerator can emit:

• 🔄 Low-frequency hum (25–45 dB) - compressor operation. In inverter models, the sound is smoother, in conventional ones - with pulsation.
• 💨 Air noise (up to 40 dB) - circulation of flows during cooling or defrosting (system No Frost).
• 💧 Gurgling or liquid overflow - movement of refrigerant (freon) through the pipes of the circuit.
• 🔊 Clicks - activation of the thermostat or compressor relay (especially noticeable when turning on/off).

These sounds may intensify in the first hours after connecting a new refrigerator or after defrosting. Also, the hum becomes louder if:

• 🌡️ The room is hot (above +30°C) - the compressor works more intensely.
• 📦 The refrigerator is loaded with food to capacity - it is disrupted air circulation.
• 🔌 Happened power outage —after power is restored, the equipment starts in enhanced mode.

⚠️ Attention: If the refrigerator Ariston Hotpoint is louder than 50 dB (comparable to a vacuum cleaner), this is no longer the norm. Measure the noise level using a sound meter app on your smartphone.

2. The compressor: why it is humming and how to check its operation

The compressor is the “heart” of the refrigerator, and its noise most often bothers owners. Models Ariston Hotpoint use two types of compressors:

• Ordinary (linear) — turn on/off with pauses, emitting a loud hum (up to 48 dB) and clicks.
• Inverter —operate continuously at reduced power, the noise is more uniform (35–42 dB).

If the compressor starts to make noise louder than usual, check:

1. Location of the refrigerator: it should be on a flat surface, without distortions. Use a level or check if the equipment is shaking when you press it. corners.
2. Gaps around the body: the minimum distance to walls and furniture is 5 cm (for models with No Frost - 10 cm). If ventilation is poor, the compressor overheats and wears out.
3. Condition of the legs: over time, the rubber shock absorbers wear out, and vibration is transmitted to the body. Check if the legs are wobbly.

If the compressor does not turn off for more than 2 hours or makes noises metallic clanging, this may indicate:

• 🔧 Wear of the piston group (typical for refrigerators older than 8 years).
• 🧊 Refrigerant leak —the compressor is trying to compensate for the deficiency freon.
• 🌡️ Thermostat malfunction —the sensor incorrectly reads the temperature, causing the compressor to work without stopping.

Listen for any extraneous sounds (grinding, knocking) during operation-->

3. No Frost fan: crackling, whistling and other sounds

Models Ariston Hotpoint with the system No Frost (for example, HBM 1192, CBA 3301) are equipped with a fan for uniform distribution of cold air. Its operation may be accompanied by:

• 🌀 A slight buzzing — normal rotation sound. blades.
• 🍃 Air flow - heard when the door is open or in a quiet room.

But if you hear:

• 🔊 Loud crackling or grinding - perhaps the fan blades touch ice or a foreign object (for example, a piece of packaging).
• 🎵 Whistling or howling —a sign of bearing wear or deformation of the blades.
• 🛑 Sharp impacts —the fan is blocked ice (often after a power outage).

To fix the problem:

1. Unplug the refrigerator for 10-15 minutes, then turn it on again. Sometimes this is enough for the ice to melt.
2. If there is noise. remained defrost the refrigerator completely (minimum 12 hours). In models No Frost ice may form in hidden areas.
3. Check whether a foreign object (for example, a label from product).

⚠️ Attention: Do not try to disassemble the fan yourself - in models Ariston Hotpoint it is located next to the evaporator, and careless actions can lead to freon leakage.

4. Problems with the condenser: hum and overheating

The condenser (grid on the back wall of the refrigerator) is responsible for cooling refrigerant. If it is contaminated or damaged, the compressor wears out, which leads to increased hum i overheating. Ariston Hotpoint the capacitor often suffers from:

• 🕷️ Dust and cobwebs - accumulate on the grille, worsening heat transfer.
• 🐾 Pet hair - especially important if the refrigerator is located next to the place where the pet sleeps.
• 🔧 Mechanical damage - bent tubes or corrosion.

How clean the condenser:

1. Disconnect the refrigerator from the mains.
2. Move it away from the wall (it is more convenient to work with an assistant).
3. Carefully vacuum the grille or remove dust with a soft brush. Do not use metal objects - it can be damaged tubes.
4. Check whether the tubes are bent. If so, call a specialist to restore the shape.

If after cleaning the noise does not decrease, more serious problems are possible:

• 🔥 Overheating of the compressor due to a faulty condenser fan (available in some models, for example, HBM 1382).
• 🧊 Clogged capillary tube - the refrigerant is not circulates normally, the compressor works without stopping.

5. Malfunctions requiring repair

If you have ruled out all “household” causes of noise, but the refrigerator Ariston Hotpoint continues to operate loudly, the problem may lie in serious damage. Let's consider the most common ones:

5.1. Refrigerant leak (freon)

Symptoms:

• The compressor works without stopping, but the refrigerator does not cool.
• On the back wall you can see oily stains (freon is mixed with oil).
• The noise becomes higher frequencyas if the compressor is “whistling.”

Cause: microcracks in the tubes or corrosion of the condenser. It is impossible to eliminate the leak on your own - soldering equipment and refilling with freon are required.

5.2 Wear of the motor-compressor

Signs:

• The hum is accompanied by a metallic knock or a grinding.
• Compressor does not turn on or turns off a few seconds after start.
• There is a strong vibration on the refrigerator body Severe vibration.

Reason: exhaustion of the resource (the average compressor life is 10–15 years). In some cases, changing the oil helps, but more often it requires installing a new motor.

5.3. Malfunction of the starting relay

Symptoms:

• Compressor clicks, but does not start.
• The refrigerator doesn’t freezealthough the light inside is on.
• Audible 5-10 minutes after switching on loud bang (protection is triggered).

Cause: oxidation of contacts or failure of the relay coil. The part is inexpensive, but to replace it you need to know the model of the refrigerator (relays are selected individually).

⚠️ Attention: If you suspect one of these breakdowns do not delay repair. Operating a faulty compressor "for wear" can lead to fire hazard (overheating of the windings) or total failure equipment is out of order.

6. How to reduce the noise of an Ariston Hotpoint refrigerator with your own hands

If the diagnostics did not reveal any serious damage, but the noise still bothers you, try these methods:

• 🔧 Adjust the legs: tighten them so that the refrigerator is stable, without distortions.
• 🧲 Install anti-vibration pads: you can buy them in hardware stores or make them from rubber. Glue them under the legs.
• 📦 Redistribute food: place heavy cans and bottles on the lower shelves, and light ones on the upper ones. This will reduce the load on the shelves. compressor.
• 🌡️ Reduce the room temperature: if the refrigerator is located next to a stove or radiator, move it or install a heat-reflecting screen.
• 🔌 Check the outlet: loose contact can cause voltage surges that cause the compressor is unstable.

If the refrigerator Ariston Hotpoint makes noise only at night, the reason may be network voltage drop (many houses are connected to a “night” tariff, and the network is overloaded. In this case, it will help voltage stabilizer.

What to do if noise appears after moving?

If the refrigerator began to make noise after transportation, most likely the compressor fastenings were loosened or the shock absorbers were damaged. In this case:

1. Disconnect the equipment from the network for 4–6 hours (let the oil drain into the compressor).

2. Check whether the compressor is touching the housing or pipes.

3. If the noise does not disappear, call a technician to adjust the fasteners.

7. technicians: checklist for owners

Not all problems can be solved on your own. Contact the service center if:

The refrigerator makes a noise louder than 50 dB (like a vacuum cleaner)|

The compressor does not turn off for more than 2 hours|

Oil stains are visible on the back wall|

The refrigerator does not cool, although the light inside is on|

You can hear a metallic grinding or knocking-->

When you call a technician, check:

• Refrigerator model (located on a sticker inside the chamber or on the back wall).
• When the noise appeared and how it changed over time.
• Were there voltage drops or power outages.

The cost of repairs depends on the breakdown:

• 🔧 Replacement of the starting relay: from 1,500 to 3,000 rubles.
• 🧊 Refilling with freon: from 3,500 to 6 000 rub.
• 🔄 Replacement of the compressor: from 8,000 to 15,000 rubles (depending on the model).

⚠️ Attention: Parts for refrigerators Ariston Hotpoint may vary even within the same series. is the spare part specifically for your model.

8. Frequently asked questions about the noise of Ariston Hotpoint refrigerators

🔊 Why is the new Ariston refrigerator noisier than the old one?

Modern models are equipped with a system No Frost and fans that create additional noise. refrigerators often use inverter compressors - they operate continuously, but at reduced power, which can be perceived as a “background” hum. If the noise does not exceed 45 dB, this is normal.

🌡️ The Ariston refrigerator is humming and does not freeze - what to do?

This is a sign of one of the serious breakdowns: leaks. freon, compressor malfunction or clogged capillary tube. Disconnect the refrigerator from the network and call a specialist. Self-repair can aggravate the problem.

🔌 Can the noise of the refrigerator be related to the voltage in the network?

Yes. If the voltage is below 200 V or above 240 V, the compressor is unstable, which leads to increased hum or vibration. Install voltage stabilizer or a surge protector.

🛠️ How often should you clean the refrigerator condenser? Ariston?

It is recommended to clean the condenser grille every 6 monthsIf there are animals in the house or the refrigerator is in the kitchen with an active stove, cleaning should be done every 3 months.

📅 After how many years does the refrigerator compressor begin to make noise?

The average service life of the compressor is 10–15 years. After 8–10 years of operation, it may appear additional vibrations or knockingrelated to wear of the piston group. If the refrigerator is more than 10 years old, noise may be a harbinger of an emergency. breakdowns.
