If a new unit is constantly gurgling and making noise, there is no way to fix the problem, the system uses isobutane as the refrigerant. The units are tested at the factory for noise level, which is less than 50 decibels.
You hear the refrigerator humming particularly loudly when the door is closed. When the door is open, the compressor automatically shuts off and the movement of the refrigerant stops. When the door closes, the system turns on and freon starts gurgling through the tubes.
The refrigerator has been disconnected for a long time and started gurgling loudly when plugged in. It takes time for the machinery to settle down to a regular mode; the sound level decreases after a couple of days.
Often the main reason for the increased noise of the refrigerator is the compressor. It is the power unit that can create sounds with a hum and a knock. If the motor is old, the pistons and wheels may be worn out. The performance of the unit is disturbed – the work of the motor is accompanied by a hum, and a rumble, the system starts up with decompression braking. The unit is unusable, replacement is required.
If the refrigerator compressor began to noise at the moment of start and stop, the reason can be the weakened shock absorbers. They can be adjusted. A strong hum of the compressor can be heard if the motor is defective. The part should be replaced.
It happens, the compressor of the old refrigerator suddenly began to make a lot of noise whistling, heating – the reasons may be different – the lack of freon or the work of the motor with an increased load. Perhaps the capillary tube is clogged, or there is excess freon in the system. In each case, the final diagnosis will be made by a specialist.
If the refrigerator became strongly noisy, the reasons can be different – the chambers frosted over, the centering of the device disturbed, the fasteners loosened, the fan with icy blades works loudly or there is a backlash in the motor bearing. It is necessary to carry out diagnostics and inspection of the unit units.
If the refrigerator has been installed incorrectly, during the operation, because of the vibration, the compressor motor may move from its mounting pads. Adjust the feet of the refrigerator so that it stands strictly vertically.
You can try putting something soft and resilient, such as rubber or linoleum, under the motor or its mounting pads.
Make sure that the distance from the compressor to the wall is at least 5-7 cm.
It is possible that you are just unlucky, and the loud operation of the compressor is a design feature of this model or a defect in your particular instance. In the first case, you can not do anything, in the second case, you should contact the warranty repair shop.
The compressor begins to work more intensively, and accordingly, the noise, immediately after a long downtime: you have not closed the door of the chamber for a long time, when you first turn on the device, after defrosting, etc. This is a normal procedure, you just need to wait until the set temperature in the chamber is reached.
A strong hum in the back can also indicate a breakdown of the compressor motor: if it is very hot to the touch, then you are out of luck and need to replace it.
If your fridge is humming when it has been in good working order, it can be because of the natural wear and tear of the compressor: call a master, and he will decide what to do with it.
When the compressor is in good working order it never works continuously. The motor turns on briefly every 20-25 minutes and turns off after reaching the user-defined temperature inside the working chamber. While the motor is running, a quiet, even hum is heard, which is the absolute norm for all Electrolux refrigerators.
Whether you can find the breakdown on your own or at some stage of the search, calling a handyman is up to you. Not only that, in the absence of experience disassembly and assembly of refrigerator is better to limit the external examination and search for simple damage, and then call our master.
