If your refrigerator has a defrosting circuit, you should check the defrosting circuit to see if it works properly. Temperature Controller Troubleshooting The premise of troubleshooting the temperature controller is that the refrigeration effect is normal, and the compressor can not stop. Many people do not know how to fix the refrigerator compressor, and this article will introduce to you how to fix it. If the refrigeration effect is normal, the temperature controller will tea canister wholesale be failed. Due to the frequent use of the refrigerator, the refrigerator compressor will inevitably occur faults. The condenser is equivalent to a heat exchanger, which turns the high-temperature and high-pressure gaseous refrigerant into low-temperature and high-pressure liquid refrigerant.

The expansion valve of a refrigerator is replaced with the capillary tube commonly because it arrives suddenly from a big tube to a small tube, and there can be the effect of throttling likewise. You remove the thermostat, put it in the freezer, then close the door, short-circuit the two wires connecting the thermostat, and make the compressor run for about 30 minutes. Fix a Refrigerator Compressor that is Running Non-Stop If a refrigerator compressor fails to stop, the key point for its maintenance is the cooling effect. There&39;s an easy way to tell if a thermostat contact breaks.The refrigerator compressor is the core of a refrigerator and achieves the cooling effect. However, it should be noted that the ice in the liner is too thick or the food is of extremely high temperature and the quantity is large, which will also lead to the compressor not stopping.

But the system can cool, even if it is not so good. If this cooling effect is not achieved, the system is low on the Freon and you need to refill it. Then you take out the temperature controller and quickly test its two contacts to see if they disconnect with a multimeter R×1. In addition, according to the needs of control or use, you can choose to install the pressure controller, temperature controller, filter dryer, and other auxiliary devices, the four major parts are necessary, though. If you&39;re confused about how to fix a refrigerator compressor, please check out this article. To determine the cooling effect, you can put a bowl of cold water in the freezer of the fridge, and put the thermostat in a strongly cold position. If your refrigerator does not have a defrosting circuit, you can first shut it down, and artificially frost it, and then turn on the power, so as to solve the non-stop fault. When the compressor is working, the gaseous refrigerant is compressed into the high-temperature and high-pressure gas and enters the condenser. The refrigerant enters the evaporator again for transferring heat and being gasifying, thus becoming the gaseous refrigerant of high temperature and low pressure, and finally returns to the compressor to continue the above cycle. You can make a judgment that if the temperature controller is normal according to this principle, as well as whether the system lacks the Freon. This also leads to the system temperature is high, so that the compressor does not stop. For this, you need to add the Freon to it. You should re-adjust them to observe the cooling effect. In addition, there are obvious temperature differences in the upper, middle, and lower parts of the condenser. Otherwise, it is because the cooling system lacks the Freon and the temperature can not drop to the control point, which leads to the failure of stopping.

You feel the exhaust pipe of the compressor and the intake pipe of the condenser that is hot, about 50℃-60℃. Freon Leakage If you touch the exhaust pipe of the compressor by hand, it does not feel hot, nor does the intake pipe of the condenser.. Lack of Freon There is another phenomenon that the system lacks Freon. And the temperature of the liner cannot drop, which indicates that the Freon in the system has been leaked out. The temperature in the box is not reduced, the contact of the temperature controller is constantly disclosed, and the power supply of the compressor can not be cut off, thus the compressor has been running. This phenomenon is called Freon leakage. An expansion valve is a throttling device, the pressure of the refrigerant out of the expansion valve drops, the temperature drops, and finally, it becomes two phases of gas and liquid. Therefore, the compressor cannot be stopped because the temperature controller is faulty. The contacts of the thermostat are closed at room temperature and can be disconnected at preset low temperatures. Therefore, when you are faced with problems in the refrigerator compressor, it is best to ask professional maintenance workers for help, so as to avoid damage to the refrigerator compressor. If it is still not disconnected at a low temperature, it may indicate that the thermal agent has been completely leaked. After you release the Freon from the system, you need to inspect leaks, pump it and add the Freon, seal it, and follow the maintenance process described above. Under normal circumstances, it can be reached in 30 minutes. If the cooling effect can be achieved, it indicates that the cooling system is normal. If the contact can be disconnected and the heat detector does not deviate from the normal sensing position, it shows that the system is lacking the Freon. If the compressor still does not stop, you need to examine the temperature controller again. Therefore, it is crucial to detect leakages during repair, and then pump out the Freon. At this point, the temperature of the refrigerated room can be reduced to less than 10℃. When you encounter a non-stop fault, you should first stop the compressor power for a few minutes, and then determine the cause of the fault according to the following phenomena. You must adjust the thermostat to a medium-cool mode before putting it in the fridge.
