The freezer does not freeze, not because of breakdowns of the unit itself, but because of simple carelessness during operation. Before you make your refrigerator the verdict "broke", be sure to look at the data of the thermostat. The optimal position, in which both the food is normal and there is no excessive load on the motor, is between 3 and 4. Perhaps you, inadvertently, yourself unscrewed the regulator to a minimum, which caused a thaw in the freezer?
An equally common reason is freezing ice. If there is so much of it that the seal is loose, warm air enters the freezer. When the engine is resting, the ice melts and a puddle forms under the refrigerator. It is necessary to defrost the refrigerator and thoroughly wipe the rubber seal.
If the temperature setting is correct and no ice blocks are found, and the freezer still does not work, then there is some problem.
Range of possible problems:
Most likely, the motor-compressor of the freezer is out of order. As a rule, this occurs as a result of natural wear and tear during long-term operation of the unit, or due to excessive load on the motor (for example, you set the freezer thermostat to the maximum minus in hot weather)
Air sensor of the freezer is faulty. In this case, the control module does not receive information that the temperature in the freezer is lower than the preset one, and does not turn on the motor for cooling.
The thermostat (thermostat) of the freezer compartment is out of order. A faulty thermostat does not inform the "brain" of the refrigerator that it is warm in the freezer, therefore the control element does not switch the motor to cooling the freezer (in single-compressor models) or does not turn on the motor at all (in two-compressor models).
Sometimes, in single-compressor refrigerators with a system "Noufrost" and the weeping evaporator fails the switching valve. It “sticks” in the “cooling the fridge and freezer” position, resulting in insufficient capacity to cool the freezer compartment. As a result, it is warm in the freezer.
There was a leak of freon through the steel circuit. This problem is typical for models with a bottom freezer and a “crying” evaporator in the refrigerator compartment. Blockages in the drainage system cause water to collect underneath the fruit and vegetable drawers and run off to the top and front of the freezer. At this point there is a steel circuit protected by plastic. If water finds microcracks and enters through the plastic onto the steel circuit, corrosion begins. Subsequently, this leads to the appearance of holes through which freon escapes.
It is possible that the circuit was damaged and freon leaked. Especially if you "helped" the refrigerator by breaking ice or putting a bowl of hot water inside the freezer. Attention: please don't rush your refrigerator! Chipping off ice or defrosting by heating is the surest way to "kill" modern units. Only old Soviet models could withstand such operations!
There was a problem in the control module. In this case, the refrigerator is outwardly in perfect order, but the freezer does not freeze, since the "brain" of the unit does not give the command to cool the freezer. If you need help with freezer repair San Jose, call us right now!
