The situation when you open the refrigerator door, and it’s warm inside, can take any home cook by surprise. It’s especially a shame if the brand’s equipment Stinol served faithfully for many years. However, there is no need to panic ahead of time: the lack of cold does not always mean that the unit has completely failed and requires replacement.
Often the problem lies in violation of operating rules or malfunctions of electronic components, which can be fixed independently. In this article, we will analyze in detail the main reasons why The Stinol refrigerator has stopped freezingand create an algorithm of actions to identify the malfunction.
The first thing to do when a problem is detected is to conduct an initial visual inspection and listen to the operation of the motor. This will help narrow down the range of possible faults and understand whether you need to call a technician or whether you can do the repair yourself.
Primary diagnostics: listen and inspect
Before disassembling the unit or looking for the service center number, you need to carry out basic diagnostics. Often the answer to the question why Stinol refrigerator it freezes poorly lies on the surface. Carefully inspect the back wall and listen to whether the compressor makes characteristic operating sounds.
If the motor hums, but there is no cold, or it turns on for a few seconds and turns off, these are different breakdown scenarios. It is important to determine whether the cooling system is working at all or whether there is a problem in the air circulation.
- 🔊 The sound of a running compressor: if the motor hums smoothly, but there is no cold, there may be a refrigerant leak or a blockage in the system.
- 🔇 Complete silence: if the unit is silent and does not respond to being plugged in, the problem may be electrical, thermostat or start relay.
- ❄️ Uneven cooling: if the freezer is working in one compartment, but the main one is warm, check the No Frost system or dampers.
⚠️ Attention: If you smell burning or see sparking in the compressor area, immediately unplug the device. Further operation may lead to a fire.
Problems with the thermostat and sensors
One of the most common reasons why The Stinol refrigerator does not turn on or is idling is a malfunction of the thermostat. This component is responsible for maintaining the set temperature inside the chambers. If it fails, the compressor may simply not receive a signal to start.
In electronically controlled models, temperature sensors are responsible for this function. Their readings may be distorted due to oxidation of contacts or software failure. Check whether the indicators on the control panel are lit or flashing in emergency mode.
Mechanical thermostats are characterized by loss of bellows tightness or sticking contacts. In this case, the adjustment knob may become jammed and it will stop clicking when turned. Replacing the thermostat is a simple procedure, but it requires care when connecting the wires.
It is worth noting that in some models Stinol with the system No Frost the failure of one of the defrost sensors can block the operation of the compressor to prevent icing of the evaporator. The self-diagnosis system puts the unit into emergency mode.
Faults of the compressor and start relay
The heart of any refrigerator is the compressor. If The Stinol refrigerator hums, but does not freeze, or a click is heard and silence sets in, the problem often lies in the motor or its harness. The starting relay is responsible for starting the engine; if it burns out, the compressor will not be able to gain the required speed.
You can determine a relay malfunction by a characteristic click when you try to start. If after the click the motor does not start and after a few seconds the shutdown click is heard again, the relay requires replacement. This is a consumable item that often fails during power surges.
A more serious situation is a breakdown of the compressor itself. An interturn short circuit of the winding or jamming of the piston group leads to the motor humming, overheating and being switched off by thermal protection. In this case, a professional replacement of the unit is required.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Clicking, silence, there is cold | Normal operation thermostat | Not required |
| Humming 5-10 seconds, clicking, silence | Malfunction of the starting relay | Low (part replacement) |
| Strong humming, then shutdown | Compressor jamming | High (motor replacement) |
| Works continuously, does not freeze | Freon leakage or blockage | Average (filling/cleaning) |
☑️ Compressor diagnostics
Freon leakage and blockages in the system
If the engine runs non-stop, hums, but the temperature inside the chambers is higher than normal, most likely there is a problem in the refrigerant circulation system depressurization. Freon leak is a common problem with older models Stinol, especially if corrosion has damaged the door perimeter heating circuit or the evaporator.
Visually it is difficult to detect a leak, since freon is a gas without color and smell. An indirect sign may be swelling of the back wall inside the freezer or the appearance of oily spots where the tube is damaged. Also, there may be no condensation on the tubes, which usually forms during normal operation.
Another option is technical blockage of the capillary tube. Compressor wear and tear or moisture that has entered the system clogs the thin channel and the refrigerant cannot circulate. In this case, the filter drier is often covered with frost or, conversely, remains warm.
⚠️ Attention: Self-filling the refrigerator with freon is prohibited without special equipment and a license. Incorrect refilling or use of the wrong refrigerant will lead to complete breakdown of the compressor.
Failures in the No Frost system
Owners of models with automatic defrosting are often faced with a situation where The Stinol refrigerator does not freeze the top, although everything is frozen below, or vice versa. This indicates a violation of the circulation of cold air between the chambers.
The main culprit (culprit) here is the evaporator defrost system. If the defrost heating element, timer or defrost sensor fails, the evaporator becomes overgrown with ice. The fan, which should drive cold air into the chamber, is blocked by ice slush or simply does not turn on due to a sensor error.
The result is the formation of an “ice coat” behind the back wall, which is not visible from the outside. Air stops flowing into the refrigerator compartment and food begins to spoil. A complete defrosting of the unit is required within 24 hours and diagnostics of the defrosting elements.
How to check the defrosting heating element?
To check the heating element, you need a multimeter. It is necessary to ring the spiral for resistance. If the device shows a break (infinity), the heating element has burned out and requires replacement. Normal resistance is usually several hundred ohms.
It is also worth checking the fan. If its impeller is frozen in ice or the motor winding is burned out, air circulation is physically impossible, even if the evaporator is cold. Noisy operation or a complete absence of rotation sound are signs of malfunction.
The influence of the external environment and operating rules
Sometimes the reasons for the lack of cold are trivial and associated with violation of operating conditions. Stinol refrigerator, like any equipment, is sensitive to the temperature in the room. If the unit is placed near the battery, in direct sunlight or in an unheated garage in winter, its operation is disrupted.
Putting it tightly against the wall disrupts the ventilation of the condenser (grids at the back). The compressor overheats and goes into protection. It is also important to check the tightness of the rubber seals on the door. If the magnetic tape is weakened or the rubber is cracked, the cold will evaporate and the motor will run idle.
- 🌡️ Temperature conditions: do not put hot foods inside, this sharply increases the load on the system.
- 🚪 Tightness: check if crumbs are stuck in the seal, interfering with closing.
- 🧊 Loading: do not overcrowd the chambers, air must circulate between the products.
Why does the Stinol refrigerator work, but does not freeze after defrosting?
If after defrosting the cold does not appear within 2-3 hours, there may be a blockage in the system (the water has turned into an ice plug in the capillary) or a freon leak has occurred during the process of breaking off the ice with sharp objects. The thermostat could also have failed.
Is it possible to use a Stinol refrigerator if it is on the balcony?
Operation at temperatures below +5°C or above +35°C is not recommended. The oil in the compressor thickens in the cold, which leads to breakdown, and in the heat the condenser does not have time to give off heat, and the motor overheats.
How long should the refrigerator cool down after transportation before turning it on?
If the refrigerator was transported lying down, it needs to stand upright for at least 4-8 hours (or better yet, a day) for the oil to drain into the crankcase compressor. Switching on ahead of time can lead to water hammer and damage to the valves.
