Gree air conditioner display 146? What is the problem with Gree air conditioner display 13?

Refrigeration during protection: the compressor is stopped, and the internal fan is running; Heating: All loads are stopped.

High voltage protection via pressure switch.

Detect whether the operating pressure of the system is too high, the pressure switch is normally closed under normal conditions, disconnect the protection switch when the pressure is too high, input the signal to the controller, and stop the operation of the compressor to protect the long-term reliable operation of the compressor.

2. Check the fault point:

The high-voltage switch is faulty or the wiring is loose.

The electrical box of the outdoor unit is faulty.

The speed of the indoor and outdoor motors is low (cooling and heating rooms).

The indoor and outdoor air inlet and outlet environment is not smooth (refrigeration outdoor heating room), and the indoor and outdoor heat exchangers are dirty (refrigeration outdoor heating room).

System blockage (dirty blockage, ice blockage, oil blockage, weld blockage, small valve not fully opened) There is air in the system.

Gree air conditioner display 146, so that Gree air conditioner display 146, it should be the problem of failure, look at the instruction manual or ask professional personnel to overhaul or after-sales customer service in the middle of the month.

FO Fault**: Refrigerant leakage.

1.This protection occurs when the valve is blocked or in the state of fluorine deficiency.

2.Charging mode: System fluoride deficiency or blockage protection, exhaust protection.

3.Represents system fluoride deficiency or blockage protection.

Indicates a refrigerant leak. If the new machine is not installed, it will generally not leak. It is also possible that the protection is caused by a malfunctioning part.

: Gree doesn't have this yet**, the air conditioner is inverter, is it fixed-frequency? The fixed frequency is that the motherboard is broken.

This should be a system failure, is there an air conditioner to restart, or switch the power supply, and then reconnect it.

Some of the displays of Gree air conditioners, most of them are running, and there may be some numbers representing specific patterns.

It should be a fault**, you can check what is the problem of the fault of 146**? Well, you can consult customer service to see how to solve it?

This is a fault of Gree air conditioner**, it may be that there is a problem with the circuit of your air conditioner, which causes the compressor not to start, you can find after-sales service to solve it.

Hello, first of all, turn off the power. Then call the after-sales customer service, and they will deal with it as soon as possible.

There are several reasons why Gree air conditioner shows L3:

1. Check whether the pins are loose, the contact is poor or the wire is broken, the temperature signal is lost after loosening, and the system will not work.

2. Check whether the temperature sensor of the indoor unit is damaged, there will be no temperature signal if the sensor is broken, and the sensor can be replaced.

3. Check whether the filter screen of the indoor unit is blocked, clean the filter screen, and the specific operation steps are as follows:

1. Turn on the air conditioner panel.

2. Pull and hold the air conditioner filter.

3. Remove the air conditioner filter.

4. Clean the air conditioner filter.

5. Replace the air conditioner filter.

Summary. Hello dear<>

Glad your question Gree air conditioner display 145 The reason for Gree air conditioner display 145 is the phenomenon of the compressor protection device tripping. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high. 1. Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately. 2. Poor heat dissipation.

Check the condenser pipe for dirt and dirt and clean the condenser. 3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned. 5. Fluoride deficiency is also possible.

When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

Gree air conditioner shows 145

Please wait patiently for a few minutes, it is being sorted out, and we will answer you immediately.

Dear, hello [Flower Shengcha], very happy for your question Gree air conditioner shows 145 The reason why Gree air conditioner shows 145 is the phenomenon that the compressor protection device jumps. Compressor overload will trip, which means that the high pressure of the system is too high or the overheating current is too large. 1. Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately. 2. Poor heat dissipation.

Check the condenser pipe for dirt and dirt and clean the condenser. 3. The pipeline system is clogged. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned. 5. Fluoride deficiency is also possible.

When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

Hello dear, <>

If my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your wide concession and praise, your efforts are very important to me, and your support is also the driving force for my progress.

Hello, Gree air conditioner display 145, there are the following reasons for the beam base grinding: 1. The power supply is not connected or there is no power, check whether the power supply, wires, and sockets are in poor contact with Fengjing, and check whether the power supply guide rubber bucket wire is aging, and the power supply problem will cause the air conditioning compressor to not work. 2. If the circuit is faulty, check whether the circuit is normal, 3. The voltage is not enough, so that the host cannot be started; A voltage regulator can be installed.

4. If the button on the temperature controller is not dialed to the appropriate position, the compressor cannot start running.

Gree air conditioner has 144** faults, only H4 faults, which is a system failure.

Meaning of alarm**: system failure, air conditioning work detection internal pipe temperature abnormality 3 times to report the fault, the internal temperature is too high, the temperature sensor feels that the temperature is not within the appropriate range to change, and the alarm will be made.

Solution: Open the shell of the internal machine to clean up the internal machine and the internal dust and garbage, and practice the after-sales repair personnel to repair.

The extender takes the information sensitive socks:Other Gree Air Conditioner Alarm ** Meaning:

1. E1, system high voltage protection.

2. E2, anti-freeze protection of the internal machine.

3. E3, system low voltage protection.

4. E4, compressor exhaust protection.

5. E5, low voltage overcurrent protection.

6. E6, communication failure.

7, e7, mode conflict.

8. E8, anti-high temperature protection.

Summary. Hello, I am glad to serve you, about the question you asked, "how to solve the problem of Gree air conditioner display 144" has been queried for you as follows: 144 appears after Gree air conditioner heating, which may indicate that the system is abnormal, solution:

1.Check whether the pressure of the system is heating when it is there. 2.

Check that the system is not dirty, and if it is, it needs to be cleaned.

Hello dear, I am happy to serve you, about the question you asked, "how to solve the problem of Gree air conditioner difference track rise display 144" has been queried for you as follows: Gree air conditioner appears 144 after heating, which may indicate that the system is abnormal, solution: 1

Check whether the pressure of the system is heating when it is there. 2.Check whether the system is dirty, and if it is dirty, it needs to be cleaned.

144 appears after Gree air conditioner heating, which may indicate that the system is abnormal, and the method of unrubbing and arguing is: 1. Check whether the pressure of the system is heating when it is there. 2. Check whether the system is dirty and blocked, if it is dirty, it needs to be cleaned.

3. Check whether the compressor is deficient in fluorine, if it lacks pure fluorine, it needs to be fluoridated. Excluding the above, it may also be a positive indication of air conditioning defrosting.
