The refrigerator makes a cricket sound: what does it mean and how to fix the problem

If your refrigerator suddenly starts making strange sounds that resemble the chirping of a cricket, do not rush to panic. In most cases, this is not a breakdown, but a feature of the operation of the equipment or a signal of a minor malfunction that you can fix yourself.

Crackling, clicking or periodic chirping - a common phenomenon for many models, especially with system No Frost or inverter compressors. However, you should not ignore such sounds: they may indicate wear of parts, improper installation, or even a threat of overheating.

In this article we will analyze all the possible reasons why the refrigerator makes a cricket sound, and we will explain in detail what to do about it. From simple solutions (for example, rearranging equipment) to complex ones (replacing a fan or relay). And if the problem turns out to be serious, we’ll tell you when to call a repairman.

Why the refrigerator crackles like a cricket: 7 main reasons

The chirping of a refrigerator is rarely accidental. This is usually the result of one of the systems or its malfunction. Here are the most common reasons:

• 🔄 Compressor operation —clicking when turning on/off, especially in models with inverter control (LG, Samsung).
• ❄️ Automatic defrosting —ice cracking when defrosting in systems No Frost or Frost Free.
• 🌀 Blower fan —if the blades touch the ice or body, a rhythmic chirping appears.
• 🔌 Compressor start relay —the faulty relay clicks with pauses, simulating the sounds of insects.
• 🧊 Thermostat or temperature sensor —when activated, it may make short sounds.
• 🏠 Incorrect installation —vibration from an uneven floor or nearby furniture.
• ⚡ Electrical problems —voltage surges cause parasitic clicks in the start-up relay.

To accurately determine the source of the sound, listen: rhythmic chirping usually associated with a fan or compressor, and single clicks - with a relay or thermostat. If the sound appears only when the door is opened, the problem is most likely in the system. data-i="75">Only at night No Frost.

Compressor and relay: when clicks are the norm

If refrigerator periodically clicks with an interval of several seconds or minutes, the compressor or its start-up relay is to blame. In modern models (Bosch, Indesit, Atlant) this is standard behavior:

• 🔧 Inverter compressor regulates power smoothly, but when switching modes it can make quiet noises. clicks.
• ⚡ Start relay triggered when the engine starts - the sound is similar to a dry crackling.
• 🔄 Thermal protection turns off the compressor when it overheats, which is accompanied by a characteristic click.

How to distinguish normal from breakdown? Normal clicks:

• Short (less than 1 second).
• Repeated with a pause of 5-15 minutes.
• Not accompanied by a change in temperature in the chamber.

Pathological clicks (require intervention):

• Frequent (every 1-2 seconds) - a sign of a faulty start relay or winding break compressor.
• Accompanied by a hum, but the compressor does not start - it is possible motor wedge.
• Clicks with a burning smell - urgently disconnect refrigerator from the network!

⚠️ Attention: If the compressor clicks, but does not start for more than 10 minutes, and the chamber gets warm, this is a sign interturn. short circuit or failure of the relay. Further operation will lead to burnout of the winding.

No Frost system: why the fan and ice are cracking

Refrigerators with No Frost (Samsung RB37J5230SA, LG GA-B489YDQL) often make chirping sounds due to two reasons:

1. Blowing fan — if the blades touch the ice or the hull, a rhythmic cracking sound appears. This happens when:
• 🧊 Freezing of the evaporator (defrost heater is faulty).
• 🔧 Deformation of the blades (for example, after manual defrosting).

Automatic defrosting — when the ice melts, it cracks, and drops of water fall on the hot heating element, making a hissing sound.

How to check:

1. Open the freezer and listen - if the sound increases, the problem is in the fan.
2. Shine a flashlight on the evaporator (behind the back wall of the freezer). If ice is visible, defrosting is needed.
3. Try to manually turn the fan (after turning off the refrigerator!). If it clings, replacement is required.

⚠️ Attention: If, after defrosting, ice appears on the evaporator again in 1-2 days - faulty defrost sensor or heating element. Self-repair without experience can lead to damage to the freon circuit.

What to do if the fan does not spin?

If the fan does not rotate even after defrosting, check:

1. Winding integrity (with a multimeter in resistance mode).

2. Presence of voltage at the fan power connector (must be 12–24 V).

3. Bearing condition - if there is play or creaking, replacement is required.

Thermostat and sensors: hidden sources of noise

It is rare, but it happens that the chattering comes from thermostat or temperature sensor. These devices are activated when the temperature changes, and their contacts may make quiet clicks.

How to recognize:

• 🔊 The sound comes from the control panel (for example, in Atlant MXM 2835-90).
• 📉 The clicks coincide with the compressor turning on/off.
• 🌡️ The temperature in the chamber fluctuates (either too cold, then too warm).

The most vulnerable models:

• 🏷️ Indesit with mechanical thermostats (series BIAA 13, TSAA 10).
• 🏷️ Biryusa older than 2015 - sensors often oxidize.
• 🏷️ Snaige with electronic control - the relay contacts on the board may malfunction.

What to do:

1. Turn off the refrigerator and remove the thermostat (usually it is hidden under the lid inside the chamber).
2. Check the contacts for oxidation - clean with alcohol or fine sandpaper.
3. If the thermostat is mechanical, turn the regulator: the clicks should be clear, without jamming.
4. For electronic sensors (Samsung RL38NCSW) check the resistance with a multimeter (norm: 4–6 kOhm at +20°C).

Incorrect installation: when the problem is not in the refrigerator

Sometimes a “cricket” appears in the refrigerator due to external factors. Check these points before disassembling the equipment:

• 🏗️ Uneven floor — the vibration of the compressor increases if the refrigerator is tilted. Use a level!
• 🪑 Contact with furniture —if the back wall touches the cabinet, the sound resonates.
• 🔌 Bad socket —weak contact causes sparking and crackling in the relay.
• 🌡️ Overheating —if the refrigerator is standing next to a stove or radiator, the compressor works for wear.

How to fix:

1. Adjust the legs of the refrigerator - it should stand level, without distortions.
2. Move the equipment away from the walls and furniture by 5-10 cm for ventilation.
3. Check the outlet: connect another device (for example, a hair dryer). If it also cracks, replace the socket.
4. Measure the temperature near the refrigerator. If it is above +30°C, move it to a cool place.

⚠️ Attention: If the refrigerator is standing on linoleum or carpet, the vibration increases. Place rubber pads or an anti-vibration mat under the feet.

When to call a technician: 5 warning signs signals

Not all problems can be solved on your own. Contact a specialist if:

• ⚡ The compressor does not starteven though the relay clicks, there may be a break in the winding or a freon leak.
• ❄️ Ice in the freezer does not melt even after defrosting - the defrost heater is faulty.
• 🔥 A burning smell appears - a sign of a short circuit in the winding or control board.
• 📉 The temperature in the chamber does not hold, although the compressor runs without stopping.
• 💧 There are puddles under the refrigerator, and the sound is accompanied by gurgling - a freon leak is possible.

The cost of repairs depends on the breakdown:

If the refrigerator is under warranty, do not disassemble it yourself this voids the manufacturer’s obligations. Contact the service center with a receipt and product passport.

⚠️ Attention: Prices and repair times may vary depending on the region and model of the refrigerator. Check details with the craftsmen before starting work.

Prevention: how to avoid chirping in the future

To keep the refrigerator running quietly, follow these recommendations:

• 🧹 Defrosting - even for No Frost carry it out once at 6–12 months. Use Vacation modeif you are leaving for a long time.
• 🧴 Caring for the seal —wipe the door rubber with soapy water to prevent it from becoming tanned.
• 🔧 Checking the ventilation —do not place food close to the back wall of the freezer.
• ⚡ Voltage stabilizer —will protect the compressor from surges (relevant for cottages and old houses).
• 📦 Correct loading —not overload the shelves, especially in the fan area.

For models with No Frost:

• Do not store liquids in open containers in the freezer - this accelerates freezing.
• If the refrigerator Samsung or LG, update the firmware through the service menu (instructions in the passport).

FAQ: Frequently asked questions about the chirping of the refrigerator

❓ The refrigerator chirps only at night - why?

At night the house is quieter, so the sounds of the compressor or fan become more noticeable. Also, the reason may be:

• Voltage drop in the network (heaters and washing machines turn on at night).
• Automatic defrosting (in No Frost it often occurs in the dark).
• Vibration from a working sewerage system or elevator (if the refrigerator is on the ceiling).

Solution: move the refrigerator away from the walls, check the voltage in the socket at night.

❓ Is it possible to replace the fan in No Frost yourself?

Yes, if you have experience working with equipment. Procedure:

1. Turn off the refrigerator, take out all the food.
2. Remove the back panel of the freezer (usually it is latched).
3. Disconnect the fan power connector.
4. Unscrew the screws holding the fan and replace it to a new one (the model must match!).
5. Assemble everything in reverse order.

Difficulty: 3/5. Risks: damage to the evaporator or freon circuit.

❓ Why does the new refrigerator crack more loudly than the old one?

Modern models (LG InstaView, Samsung Bespoke) are equipped with:

• Inverter compressors that regulate power more often (hence clicks).
• More powerful fans No Frost (noisier when frozen).
• Electronic boards with relays that operate with a characteristic sound.

This is not a breakdown, but a design feature. If the sound does not increase over time, there is no need to worry.

❓ The refrigerator is chirping Atlant —what to do?

In models Atlant (for example, MHM 170-03) most often chirps:

• Start relay (cheap Chinese parts wear out quickly).
• Thermostat (in mechanical models the contacts oxidize).
• Fan, if the model c No Frost.

Solution:

1. Check the relay - if it gets hot or smells burning, replace it (costs ~800 RUR).
2. Clean the thermostat contacts with alcohol.
3. If there is sound from the freezer - defrost refrigerator for 24 hours.

❓ Is it dangerous to ignore the chirping?

Depends on the reason:

• ✅ Safeif it is normal compressor clicks or defrosting.
• ⚠️ Dangerif:
• The compressor does not start after clicking.
• A burning smell or smoke appears.
• The temperature in the chamber rises higher +10°C.

In the latter case, turn off the refrigerator and call a technician.
