The LG refrigerator makes a sound like a cricket: what to do and how to eliminate the noise

Have you noticed that your refrigerator LG has begun to make strange sounds, similar to the chirping of a cricket, crackling or periodic crackling? Such noise can appear both during the day and at night, interfering with sleep or creating discomfort. In most cases, this is not a critical breakdown, but you should not ignore the problem - some reasons can lead to serious malfunctions over time.

In this article we will analyze 7 main reasonswhy the refrigerator LG makes sounds like a cricket, and we will also give step-by-step instructionshow to diagnose and fix the problem on your own. From simple solutions (for example, adjusting the legs) to more complex ones (cleaning the fan or replacing parts). You will also find out in which cases it is better to immediately call a specialist so as not to aggravate the situation.

Why the LG refrigerator chirps like a cricket: the main reasons

Sounds similar to a cricket in refrigerator LG usually occur due to vibrations, friction or malfunctions of mechanical components. Here are the most common sources of noise:

  • 🔧 Uneven installation — the refrigerator rocks or stands at an angle, causing the compressor and other parts to vibrate.
  • 🌀 Contamination fan No Frost —the blades cling to ice or dust, making a cracking noise.
  • ❄️ Evaporator freezing —ice cracks when the temperature changes.
  • 🔌 Problems with the compressor —wear of bearings or fasteners.
  • 📦 Loose fastenings of internal parts —tubes, shelves or the capacitor is in contact with the housing.
  • 🔋 Malfunction of the starting relay —clicks and rattles when starting the compressor.
  • 🌡️ Thermoregulator or temperature sensor —activation with a characteristic sound.

Most often the problem lies in the first three points - they can be fixed independently without disassembling the equipment. If the sound appears suddenly and is accompanied by other symptoms (for example, the refrigerator does not freeze well), this may indicate wear of the compressor or electronic components.

How to determine the source of the sound: step-by-step diagnostics

Before starting repairs, it is important to localize the source of the noise. Here's how to do it:

  1. Unplug the refrigerator for 5-10 minutes, then turn it on again. If the sound appears immediately after startup, the problem is most likely in the compressor or start relay.

  2. Listen to where exactly the chirping comes from:

    • Bottom - compressor or condenser.
    • Rear in the upper part - No Frost fan.
    • Inside the chamber - evaporator or ice build-up.

  • Open the refrigerator door. If the sound intensifies, it’s the fault fan or freezing. If it disappears, the problem is tightness of the seal.

  • Try to slightly rock the refrigerator. If a cracking sound appears, you need adjust the legs or secure the tubes.

  • If after diagnostics you realized that the sound comes from fan or evaporator, you can try to fix the problem yourself. In the case of compressor or relay it is better to contact a specialist - improper repairs can damage the equipment.

    Solution 1: Adjusting the legs and leveling the refrigerator

    If the refrigerator LG is uneven, vibrations from the compressor increase, and a cricket-like chirping sound appears. This is the simplest problem that can be fixed in 10 minutes.

    Here's how to properly level the refrigerator:

    1. Take a building level (or use a leveling app on your smartphone).

    2. Place it on the top lid of the refrigerator. If the air bubble is displaced, you need to adjust the legs.

    3. Twist the front legs clockwise to raise the refrigerator, or counterclockwise to lower it. The rear legs are usually adjusted by a special mechanism (see the instructions for the model).

    4. Check that the refrigerator does not rock when you lightly press the corners.

    If the sound does not disappear after leveling, check whether the tubes or hoses are touching the back wall. Sometimes they rub against the body, making a chattering sound. Carefully bend them to the side.

    Solution 2: Cleaning the No Frost fan

    B refrigerators LG with a system No Frost the fan is responsible for blowing the evaporator. Over time, dust, ice or condensation accumulates on its blades, causing a crackling or chattering sound when rotating. If the sound intensifies when you open the door, the problem is in the fan.

    To clean it:

    1. Unplug the refrigerator and wait for complete defrosting (at least 6-8 hours).

    2. Remove the back panel in the freezer compartment (usually it is attached to latches or screws).

    3. Carefully remove ice and dust from the fan blades with a soft brush or vacuum cleaner. Do not use sharp objects!

    4. Check that the fan rotates freely. If it clings to the body, bend the blades a little.

    5. Make sure that there are no foreign objects near the fan (for example, pieces of packaging).

    After cleaning, turn on the refrigerator and listen. If the sound disappears, the problem was in the fan. If not, you may need to replace the bearing or the entire assembly.

    What to do if the fan does not spin at all?

    If after cleaning the fan does not start, check:

    1. Power —the connector may have come loose.

    2. Engine — when voltage is applied, it should vibrate slightly.

    3. Defrost sensor —if it is faulty, the fan may be blocked.

    In this case, it is better to call a technician, as diagnostics will be required electronics.

    Solution 3: Eliminating evaporator freezing

    If the refrigerator LG chirps like a cricket, and inside the freezer you can see ice on the back wall - the problem is freezing of the evaporator. This happens due to:

    • 🔁 Incorrect operation of the defrost system (defroster).
    • 🚪 Frequent or prolonged opening of the door.
    • 🌡️ Malfunction of the temperature sensor.
    • 💧 Moisture getting inside the chamber (for example, due to a leaky seal).

    To eliminate freezing:

    1. Completely defrost the refrigerator (at least 12 hours).

    2. Check the rubber seal on the door. If it is torn or deformed, replace it.

    3. After defrosting, set the temperature in the freezer to -18°C, and in the refrigerator - to +4°C.

    4. If ice forms again after 1-2 weeks, it is faulty defrost heater or timer. Replacement required.

    In LG models with the Smart Diagnosis system, evaporator freezing may be accompanied by a dH or Er IF error on the display. In this case, defrosting will not help - the control board needs to be repaired.

    Solution 4: Problems with the compressor and start relay

    If the sound is similar to rhythmic chirping or clicks, especially when starting the refrigerator, the problem may be:

    • 🔌 Start relay —it clicks when you try to start the compressor.
    • 🔄 Worn compressor mounts —vibrations are transmitted to the housing.
    • ⚙️ Compressor bearings —a hum with periodic cracking appears.

    You can independently check only the compressor mounts:

    1. Disconnect the refrigerator and move it away from walls.

    2. Remove the back cover (if there is one).

    3. Check whether the compressor is tightly secured. If the bolts are loose, tighten them.

    4. Make sure that the tubes coming from the compressor do not rub against the housing.

    If the problem is start relay or compressor, do not try to repair them yourself! This may lead to fire or freon leak. It is better to call a specialist with diagnostic equipment.

    When you need to call a technician: signs of serious breakdowns

    Not all problems with sound in the refrigerator LG can be fixed on your own. Contact a specialist if:

    Symptom Possible cause What to do
    The chirping is accompanied by overheating of the compressor (hot to the touch). Interturn short circuit in the compressor windings. Replacement of the compressor is required.
    Refrigerator does not freeze, but chirps. Freon leak or capillary tube malfunction. The tubes need to be refilled or replaced.
    Sound appears only when the door is opened and does not disappears after cleaning the fan. Faulty temperature sensor or control board. Diagnostics and replacement of electronic components.
    The display lights up error (Er, dH, FF). Failure in the defrost system or electronic module. Flashing or replacing the board.

    Average cost of repairing refrigerators LG for such malfunctions:

    • 🔧 Replacement of the start relay - from 1,500 ₽.
    • ❄️ Repair of the No Frost system - from 3,000 ₽.
    • 🔄 Replacement of the compressor - from 5,000 ₽ (excluding freon).
    • 📱 Diagnostics of the electronic module - from 2,000 ₽.

    If your refrigerator is under warranty, do not disassemble it yourself this may lead to refusal of free repairs. Contact the service center LG.

    Prevention: how to avoid the appearance of extraneous sounds

    To ensure that the refrigerator LG works quietly and does not make sounds like a cricket, follow these recommendations:

    • 📏 Check the refrigerator level regularly (once every 3–6 months).
    • 🧊 Defreeze the refrigerator at the first signs of freezing (ice thickness more than 5 mm).
    • 🧹 Clean the rear grille from dust at least once a year.
    • 🚪 Keep an eye on the seal —wipe it with soapy water and check for leaks.
    • 🌡️ Do not overload the refrigerator products - this interferes with air circulation.
    • 🔌 Use a voltage stabilizerif your network has frequent surges.

    Also avoid installing the refrigerator near heat sources (batteries, stove, direct sunlight). This forces the compressor to work harder, which accelerates the wear of parts.

    If you buy a new refrigerator LG, pay attention to models with inverter compressor (for example, series GA-B489 or GR-B459). They are quieter and break down less often.

    ⚠️ Attention: If your refrigerator LG was manufactured before 2018, some parts (for example, control boards or compressors) may be discontinued. Check their availability at the service center before repair.

    FAQ: Frequently asked questions about noise in LG refrigerators

    Why does the LG refrigerator chirp only at night?

    At night the room is quieter, so the sounds from the refrigerator become louder more noticeable. Possible reasons:

    • The compressor operates in increased mode due to increasing temperature in the chamber (for example, if the door is poorly closed).
    • Fan No Frost turns on to blow the evaporator.
    • Tubes or parts compress/expand as the temperature changes.

    Try to level the refrigerator and check the seal. If the sound does not disappear, write it down and show it to the technician.

    Is it possible to use a refrigerator if it chirps like a cricket?

    If the refrigerator freezes normally and the sound is not accompanied by other symptoms (overheating, errors on the display), then you can use it. However:

    • The chirping noise from fan or freezing over time can lead to breakdown.
    • Sound from compressor or relay indicates the risk of a serious malfunction.

    It is better not to delay diagnosis for long.

    How to distinguish normal refrigerator noise from a breakdown?

    Normal refrigerator sounds LG:

    • Quiet murmuring or gurgling (freon circulation).
    • One-time click when starting/stopping the compressor.
    • Light rumble from the fan.

    Signs of failure:

    • Rhythmic crackling or crackling.
    • Constant gnashing or squealing.
    • Sound is accompanied interruptions in operation (does not freeze, often turns off).
    How much does it cost to repair a rattling LG refrigerator?

    The cost depends on the reason:

    Problem Price (₽)
    Fan cleaning 500–1 500
    Replacing the seal 1 000–2 500
    System repair No Frost 3 000–6 000
    Replacement of the compressor 5 000–12 000

    The technician will tell you the exact price after diagnosis. In service centers LG fixed prices apply.

    Is it possible to replace the fan in an LG refrigerator yourself?

    Theoretically yes, but:

    • It will require complete defrosting disassembly freezer compartment.
    • You need to select exact fan model (for example, for LG GA-B489 suitable 6601JB1006A).
    • Yes risk of damaging evaporator or wiring.
