The u. S. Air conditioner indicated that the compressor was non-compliant。
A missing phase is one of the different circuits of the normal three-phase power source, where the original three-phase equipment reduces its output power to render it non-functional or causes accidents, and therefore the need for additional protection for some important equipment。
The main reasons for the failure of the compressor were:
1. Melting device
The malfunctioning is due to the melting of the melting unit as a result of a single or short circuit between the main circuits of the electric motor, which requires the selection of electric motors and properly installed low-voltage appliances and circuits suited to the surrounding environmental conditions, as well as periodic inspection and maintenance。
2. Acoustic tactile grinding or
When air conditioners work in poor working conditions, they result in the oxidation of the aerodynamic contact head of the contact point, causing wear and tear, severe exposure and malfunction。
Solutions:
In the event of a lack of protection, measure whether one of the three-phase cables supplied to the external aircraft is free of charge, ensuring that all three lines are 380 v, and check carefully whether the power feeder, the internal and external connection, the external connection end and the compressor link are loose or disconnected, or are tightened or reconnected。
If ee is shown after the alignment line, indicating the reverse sequence of the compressor, it is sufficient to align any of the two lines. If the matter is not resolved, contact u. S. After-sales personnel in a timely manner to report。
Extension:
U. S. Air conditioner failure codes are complete:
E1 failure cause:
Outdoor communication failure。
Low pressure alarm, inadequate refrigerant。
3. System high pressure protection。
E1 solutions:
E1 cannot repair it on its own and needs to do so。
Reason for e2 failure:
1. Power failure。
2. Temperature temperature head alert。
E2 solutions:
Press the failback button. If e2 failure is shown after pressing the double button, it may be caused by power outages or fuse melts or wiring errors. We'll have to pay for it。
E3 failure resolution and causes:
The compressor alerts the alarm as soon as the call is made, checking the integrity of the pressure protection and connection lines, and checking the sequence boards and whether the sequences are incorrect。
High/low pressure alert, if malfunctioning after 30 minutes, check whether the indoor pipe temperature sensor is correctly located。
3. The indoor winder feedback alerts and, if operated in 15 seconds, check if the indoor winder feedback lines are connected correctly。
4. Auxiliary heating (indoor wind) overheating alarm to check overheat protection。
5. Official sales personnel in contact with the united states come and repair the shop。
E4 failure cause:
This means that the compressor is ventilated with temperature failure. Outdoor cavity pipe calls。
E4 solutions:
Emission temperature sensor failure (subject to maintenance)。
2. The system is short of fluorinated fluorine。
3. System blackouts or heat dissipation are not good, and it is recommended that interior filters and exterior condensers be cleaned。
4. Official sales personnel in contact with the united states of america come and repair them。
E5 failure cause:
Low voltage overflow protection and internal tube temperature alert。
E5 solutions:
Power voltage is below 187 v. The current air conditioners are all wide power designs, but if they are below this level, they cannot be activated。
2. Protection from internal and external condensers is too dirty. It is recommended that it be cleaned first。
3. Control panel failure, resulting in electrical current instability, requires the installation of pressure stabilizers (required for repair)。
4. Official sales personnel in contact with the united states of america come and repair them。
E6 failed cause:
Communication error。
E6 solutions:
E6 is unable to repair itself and needs to be repaired。
E7 failure cause:
Outdoor ambient temperature detectors。
E7 solutions:
The temperature is too high and can only be broken by prolonged work. After-sales workers need to be contacted for repairs。
Reason for e8 failure:
