Refrigerator manufacturers try to reduce the noise level of the operating unit as much as possible. And if you compare modern refrigerating equipment with the models of 10 years ago, the refrigerators of newer collections are much quieter than their predecessors. However, it was not yet possible to completely get rid of extraneous noises.
In this article, we will discuss the main reasons why the refrigerator makes noise and when it is too early to “sound the alarm,” and when it is necessary to immediately contact a specialist for refrigerator repair in Montreal.
Search for reasons
First of all, let’s determine under what circumstances the refrigerator makes noise:
– in some cases, during cooling or freezing;
– units with the No-Frost defrost system crackle, but in addition to the crackle, there will be a clear deterioration of the temperature in the refrigerating compartment;
– when you turn on the compressor: there will be a loud crackling sound, and it will immediately shut off before it has time to work;
– after defrosting or on the first day of use of newly purchased refrigerators, although the temperature in the chambers will be correct, and the device successfully cools.
Next, we offer to consider more serious reasons why a working refrigerator may start to crackle, unrelated to the compressor motor or freon circulation system.
Common causes may be:
Crackling is observed both in new devices and in those that have been serving their owners for a long time. Therefore, the following are the reasons:
1. Poor adjustment of the fasteners. This failure appears in units regardless of their service life. New models can crackle due to poor fastener adjustment. In older units, this is mainly due to vibration acting on the housing, which eventually loosens the fasteners. An adjustment of the fasteners is required.
2. Wear and tear of the shock-absorbing parts. This again occurs on the basis of vibration. And it will be enough to replace the shock-absorbing elements.
3. A badly fixed capacitor. Under such conditions, the crack will be accompanied by a powerful vibration, so such a cause can be determined unambiguously.
4. Failure of the starting relay. Such breakdown practically puts the refrigerator out of operation; only the lamp lights up. The equipment stops freezing completely and emits the corresponding crackle. Replacement of the protection relay is required.
5. The thermostat is broken. At the same time, the light in the middle is on, but there is no cold. This means that the thermostat is not sending temperature change signals. Intermediate clicks can be traced at the same time as the crackling.
6. The compressor does not work. This is the most undesirable breakdown, as the compressor is the heart of the unit and will be expensive to replace. You will notice that the refrigerator turns on but immediately shuts off after a loud clicking sound.
As we can see, there are many reasons why your refrigerator crackles. Fast and high-quality refrigerator repair will help restore its performance and avoid further aggravation of the problem. As soon as the first signs have been noticed, contact a refrigerator repair company as soon as possible.
The company will conduct a comprehensive diagnosis of your device, determine the exact cause of failure, and identify other hidden faults if any.
