The Main Malfunctions of Refrigerators: Making the Correct Diagnosis


Often our appliances become just a necessary background in the kitchen, which should perform their functions and not bring us problems. However, sooner or later, there comes a moment when the bulb does not light up, or the refrigerator simply stops “freezing”. Then we can only helplessly watch how our food melts and deteriorates. In this case, it is very important to determine the problem to make a correct diagnosis for the subsequent “treatment” of the fridge. It is often recommended to turn to professional craftsmen who will conduct a thorough diagnosis and issue a verdict, but sometimes you can handle it yourself. To do this, you need to know the main causes of breakdowns and possible symptoms.

The main malfunctions

1. The main chamber does not freeze, but the freezer works properly

Typically, this problem may be due to a loose seal of the chamber or the bad operation of the fan. In this case, it is necessary to completely defrost the refrigerator. If these measures do not lead to a positive effect, we recommend disconnecting the unit from the power supply and contacting the master.

2. Motor starts and then immediately stops

Perhaps the problem is the motor compressor. If this is the case, the repair will not work, and the part will need to be replaced. Fortunately, you can quickly order the appliance repair in Mississauga at In rare cases, there may be problems with the control board. If the compressor runs for a few seconds and turns off, the configuration of the board will help.

3. Snow inside the chamber

In this case, it is difficult to determine the exact reason. An ice crust on the back surface of the chamber may indicate a failure of the defrosting system. “Snow” on the bottom may indicate a malfunction of the drainage system. There are also situations when the cause is a lack of tightness due to a loosely closed door, a sensor malfunction, and other factors.

4. The motor does not turn off

Perhaps, in this case, we are talking about the leakage of freon as the result of microcracks. To determine the problem, you need to turn the refrigerator. In the case of normal operation, the condenser must be hot. Also, the reason may be the complete or partial blockage of the refrigerating unit, as well as the failure of the thermostat. If your fridge experiences these symptoms, we also recommend you contact a specialist for more information.

5. Too much freeze

The most commonplace advice is to check the settings. Often, a problem can suddenly occur, when the regulator is accidentally turned to the maximum. If, after checking, you concluded that everything is ok with the settings, then we are dealing with a malfunction. Perhaps, there is a problem with the seal. In such cases, ice is formed. Also, the drainage hole may become clogged – it can be washed with warm water. Sometimes, the problem can be related to a faulty thermostat.

6. The motor does not turn on 

Most likely, this is due to a malfunction of the compressor or the thermostat. To solve these problems, knowledge of electricians is required, therefore it is highly not recommended to carry out diagnostics on your own because often, the short circuit leads to malfunctions that can become irreversible.

How to prepare the refrigerator for the master’s arrival?

The absence of any simple actions can increase the time and the price of the repair. However, the intervention in the rather complicated mechanism of the refrigerator without certain skills and experience can frequently make repairs simply impossible. In this case, the client loses money, time, and nerves.

Before calling the service centre or directly to the master, find the necessary documents for the equipment with the model name. Typically, if such information is lost, you can find the answer on the Internet. It would also be useful to inspect the refrigerator: it may be possible to visually determine the source of the problem (something sparks, the compressor is cold, there is water below, etc.). After these simple procedures, you can safely call a specialist and report a breakdown.

To repair as fast as possible, describe the problem in as much detail as possible, starting from the model name and duration of operation, ending with the symptoms. Feel free to look like an amateur in matters of repair, because it is much easier to ask again and get clear recommendations on how to proceed than to aggravate the problem. Wipe the walls and outer surface of the appliance with a damp cloth. Working in a clean environment, the master will be grateful to you and will repay you with fast and high-quality work, while saving your money and nerves.
