Usually the sound signal of the refrigerator is heard only “on business” - when the user forgets to close the door or selects a specific function in some models. You quickly get used to such sounds and stop noticing them. But what if the sound of the refrigerator is heard all the time or occurs periodically even with the door closed? If at the same time the bulbs also flash or other “symptoms” appear, then the problem is obvious.
Next, we will look at why the refrigerator squeaks, when to worry, and when not.
The refrigerator makes strange noises - when it's normal
There are times when he bothers with a squeak, but at the same time remains absolutely working. Then you need to exclude situations in which there is no question of damage:
- Check how tightly closed the door refrigerator or freezer; something may interfere with her. It is possible that the case tilts forward, which provokes the spontaneous opening of the refrigerator. To solve the problem, you need to adjust the legs so that the body is tilted slightly back.
- Maybe you decided to do a lot of frost at once, because of which the temperature inside the refrigerator increased. Unload shelves and refrigerate in batches or wait for the motor to reach the desired temperature. The standard freezer is designed to freeze 6 kg of food per day. If you loaded 6 or more kg per day to maintain the compressor, it is better to turn it off for 1 hour every day.
- Worries signal of a brand new refrigerator? Do not worry: the equipment needs time to enter the full-fledged operating mode and catch up with the desired temperature level in the compartments. For the same reasons, the refrigerator beeps after defrosting - in this case, it also needs to be given time to “disperse”.
- Look in the freezer - if you did not defrost the camera for a long time, then it could freeze a lot of snow or ice. Ice or a “fur coat” interferes with the sensor, therefore incorrect data is being received. Defrosting is required within 10-24 hours.
- Maybe, Super Freeze launched. In some models, this function turns off independently after a few hours, while others require manual intervention and stop the mode.
If the sounds continue, or vice versa - the equipment does not squeak with the door open, the system clearly has a failure. It will be useful for you to know the causes of its occurrence for prompt troubleshooting.
Why does the refrigerator squeak
If you are ready to solve a problem, but an obsessive sound prevents you from concentrating and making a decision, turn it off before a specialist arrives. Usually the shutdown button is located directly on the user panel. It is indicated in different brands and models in different ways: for example, ALARM or OK. A speaker is drawn on the Bosch models, and a crossed-out bell symbol on the Nord. If you did not find such a button intuitively, de-energize the equipment and wait for a specialist.
Important! A sound indicates a malfunction. Therefore, it is necessary not only to remove it, so as not to “unnerve. After shutting down, proceed to self-repair or call the wizard, so as not to bring the equipment to a major breakdown.
If the equipment does not just squeak with the door closed, but it also weakly cools the food, the reason for this may be:
- refrigerant leak;
- temperature sensor breakdown;
- decompression or loss of engine performance;
- electronic board failure;
- violation of the defrost system;
- cooler breakdown;
- jamming of the shutter;
- door seal wear.
These causes of squeaking can occur during normal operation of both cameras:
- The closed door sensor has broken.
- The integrity of the plume of the electronic scoreboard is violated.
- One or more buttons on the user panel are faulty.
This is a short list of possible causes of constant squeak. Next, we will understand each failure separately and give brief instructions for action.
Beeps the fridge: what to do
Breaking | Sign | Cause | Elimination |
Refrigerant leak. | In the refrigerator with one compressor, both compartments do not work, and in the model with two motors - one of them. The compressor works without shutdowns or pauses too short to compensate for the lack of cold. In some models, the LED light is on or blinking. | The system is damaged, there is a gas leak. | Find the leak, seal the system and charge the circuit with refrigerant. |
Damage to the temperature sensor. | In the model with one engine, both compartments do not freeze, with two - one. A light is on on the user panel, the motor does not rest. In electronic models, the corresponding error code is lit. | Due to the breakdown of the thermistor in the compartments, it becomes warmer, which provokes the inclusion of an alarm. | Replace faulty temperature sensor |
Failure of the motor-compressor. | 1. There is a constant squeak, the motor is constantly buzzing. The offices are too warm. There is light in the chamber. In addition to the above, indicators may flash on the panel. 2. A squeak is heard, the compressor is trying to start, but unsuccessfully. The cells are warm, the motor housing can also warm up. 3. The compressor switches off for short periods of time or does not turn off at all. The compartments are not cold enough. In addition to the alarm, red / yellow lights on the control panel may blink or light. | Damage to the components of the compressor, decompression. | Change the motor to a new one. |
Board failed. | In the single compressor model there is no cold in one of the compartments, in the refrigerator with two motors it is warm in both chambers. Failure is accompanied by a flashing red light. | Failure can be caused by voltage drop. In rare cases, factory defects are to blame. Due to the high humidity in the room, the board contacts may oxidize. | Firmware or full module replacement. |
Violation of the defrost system. | In the model with the No Frost function, the temperature regime is too high, the alarm works, the red lamp flickers. A layer of ice is cut on the evaporator. | One of the elements of the defrost system could break. | It is necessary to replace the faulty assembly. |
Fan breakdown. | In the freezer with No Frost, the temperature is high, the compressor is working, but the fan does not spin. There is a constant squeak. In the “drip” models, the second camera works as expected, and in the refrigerator with Full No Frost (full) both compartments do not work. | The cameras do not cool, because a broken cooler does not distill cold air. | Change the fan (or cooler motor, if it breaks). |
The shutter has stalled. | In systems with Full No Frost, the temperature in the compartments is too high, the ALARM lamp squeaks and flashes (Attention!). | Air does not flow from the freezer to the second compartment. This could also happen due to freezing of the shutter or a breakdown of the reed switch. The cause of the problem may be the gear motor. | Repair or replace broken parts. |
The seal was worn. | A squeak is heard constantly, and the door cannot be closed tightly. The compressor began to run less frequently. In some models, the emergency LED is lit. | The seal may be damaged if the operating rules are not followed, but natural wear is not excluded. Frequent opening and closing of doors and pops contribute especially to quick wear. | Check the tightness of the elastic by laying a small strip of paper in all suspicious places. Where the seal does not stick to the body, the paper will fall out. Gum should be glued or replaced with a new one. |
What to do if the technique freezes, but still interferes with a piercing squeak
Problem | Sign | Cause | How to eliminate |
The closed door sensor has broken. | The sound is uninterrupted. The red LED is on or flashing. | Reed switch mistakenly “thinks” that the door is open, so it constantly makes the refrigerator squeak. | Replace the sensor with a working element. |
The integrity of the plume of the electronic scoreboard is violated. | In addition to squeaking, you may find that the electronic display does not work. Damage may be accompanied by a lack of light in the chamber. | Due to the integrity of the loop, the contact of the door with the control module is lost. | Replace the screen cable. |
One or more buttons on the user panel are faulty. | It can be a start key or temperature control knobs. The squeak is heard periodically, the bulbs can glow randomly. | Broken buttons cause the user panel to malfunction. | Replace buttons or immediately the entire panel. Carry out maintenance, clean and solder unreliable connections. |
Now you know everything about why your refrigerator squeaks. Moreover - you know the causes of the squeak, and you know exactly what to do.
