If the air conditioner fails, the symbol code will also appear on the display. Let's take Haier refrigerator as an example. What's the matter with E0 in Haier refrigerator? What causes it? How to solve it? Let's get to know with Xiaobian.
Why Haier refrigerator E0
The alarm of the machine shows E0: the temperature sensor of the refrigerator / freezer is faulty, that is, the temperature controller switch is broken.
The two screens flash and display E0: This indicates that there is a fault in both the freezer and freezer.
Alarm display E0 in variable temperature area: sensor failure of variable temperature greenhouse.
The left / right temperature area of the refrigeration / freezing chamber shows E1: the evaporator sensor of the refrigeration chamber is faulty.
Cold chamber temperature display E2: cold sensor and cold frost sensor are all in fault.
In a word, E0 is generally due to the failure of the temperature controller. Replace the temperature controller.
Analysis of other faults of Haier air conditioner
1. The "operation" and "alarm" lights flash at the same time: it should be caused by the failure of the refrigeration system, such as the leakage of refrigerant, ice, dirty blockage, etc.; it may also be caused by the stuck fan blades or the falling off of motor leads and poor contact.
2. 'H' and 'e' and 'alarm' lights flash: mainly due to the open circuit, short circuit or failure of the temperature sensor, where 'e' refers to the failure of the sensor in the refrigeration room; and 'H' refers to the failure of the sensor in the refrigeration or variable greenhouse.
3. The refrigerator gear "high, low" and "alarm" flash at the same time: This indicates that the air door of the refrigerator is faulty. If the refrigerator adopts electric damper, it is driven by stepping motor. It should be that there is a problem in the motor drive part, or it may be that the in place switch fails, the signal is open circuit or the line card is in poor contact, a small part of the reason may be that the motor is poor.
4. Change the greenhouse gear to "refrigerate" and "micro freeze" flash together with "alarm": this should be caused by the failure of the air door of the change greenhouse.
5. 'l' and 'alarm' flicker: This is a phenomenon when the temperature of the refrigeration room is lower than zero. It is mainly because the air door is deformed or the air door is not closed tightly due to other reasons, resulting in too many air-conditioners entering the refrigeration room.
6. "Defrost" and "alarm" flash: This is caused by the defrost sensor loose or poor contact; or the heater of the defroster does not work.
7. 'quick freeze' and 'alarm' flash: This is caused by an open fuse on the defroster heater.
8. "Alarm" flickers: this may be caused by the failure of the refrigerator door lamp switch or the door body deformation does not contact the door lamp switch.
Sometimes the Haier refrigerator that I bought fails. For example, I can see the reason why the refrigerator shows E0 and how to solve this problem.
Haier refrigerator instructions
1. Temperature regulation
There is an adjustment and rotation button in the refrigerator. You can adjust that button to adjust the temperature. When we need quick freezing, we can adjust the gear up, the higher the gear, the lower the temperature.
2. Refrigerator use
The refrigerator is generally divided into two parts: refrigeration and freezing. We put the frozen food in the frozen layer, the fresh food in the cold layer, and some normal temperature food in the refrigerator. Do not put the overheated food in the refrigerator immediately, but put it in the refrigerator after it is cool.
3. Clean water tank
There will be a lot of water in the refrigerator when it is used for a long time. We need to clean the refrigerator sink regularly. Generally, the location of the sink of each model of refrigerator can be said to be different. It will be written in detail in the refrigerator manual.
4. Defrost
The frequent use of refrigerators will lead to a lot of ice in the freezer. We need to defrost regularly, otherwise the frost will affect the refrigeration effect of refrigerators. First, we need to stop the refrigerator, open the refrigerator door and wait for the ice to melt for a while. If you want to hurry up, you can use the hot air blower to blow it.
