What does it mean when p6 appears in the air conditioner, what does it mean when the air conditioner

P6 Fault Cause: Automatic protection of the outdoor unit of the air conditioner. When the outdoor unit fails, it will automatically shut down for protection.

Workaround:1. If the outdoor unit is installed indoors without ventilation or indoors, it will cause poor heat dissipation of the outdoor unit.

It is recommended to reposition the outdoor unit and place it in another location. It is necessary to ensure that the outdoor unit can dissipate heat normally. Other solutions are as follows:

2。If the outdoor unit is facing the direction of the sun, it may automatically shut down for protection due to long exposure time, especially in summer, when the outdoor temperature is high and the daylight hours are long. It is necessary to reinstall the outdoor unit, install it in a suitable location, and add an awning, but it should not affect its heat dissipation.

3.The outdoor unit is outdoors for a long time and is easy to accumulate dust. If there is too much dust in the outdoor condenser, it can also cause clogging.

You can use a dedicated fin cleaner to clean the condenser of your air conditioner. 4.If there is something near the outdoor air conditioner that blocks the heat dissipation of the outdoor air conditioner, remove the blocked thing to ensure the normal heat dissipation of the outdoor air conditioner.

Try not to place items outside the machine to avoid affecting the heat dissipation of the air conditioner. 5.If the compressor overheating protection device is damaged, it needs to be disassembled for repair.

The solution is to replace the compressor overheating protection device. 6.If the cylinder or coil of the compressor burns out.

The solution is to replace the compressor with a new one.

The air conditioner is faulty**P6 indicates that the air conditioner inverter module is faulty. It is possible that after the air conditioner is turned on, the instantaneous high current in the air conditioner impacts the inverter module of the air conditioner, which triggers the position protection of the DC inverter compressor of the air conditioner. In this case, you can turn off the air conditioner first, cut off the power of the air conditioner, and then turn the air conditioner back on.

Midea air conditioning. Analysis of common faults of inverter cabinets** E1: whether the compressor current is too high, whether the compressor is overheated, whether the exhaust temperature is too high, whether the module protection, overload protection is short-circuited, and whether the compressor temperature sensor package is short-circuited. E2: For indoor unit evaporators.

For antifreeze operation, it is necessary to check whether the indoor temperature sensor bag is open, and if so, it can be ruled out. E3: Short circuit or open circuit of the indoor temperature sensing packet.

E4: Indoor pipeline temperature sensing package open circuit or short circuit. e5：

For indoor and outdoor communication failures, check whether the indoor and outdoor connection lines are wrong (whether the neutral line and belt wire are reversed); Whether the signal line is loosely connected with the control room and connector; whether the controller is damaged, etc.

The air conditioner shows the meaning of P6 as follows:

1. The outdoor unit is installed without ventilation or indoors, resulting in poor heat dissipation of the outdoor unit. It is recommended to relocate the unit and adjust the position of the external unit to ensure normal heat dissipation of the outdoor unit.

2. Dust accumulation in outdoor unit or outdoor condenser. The condenser of the air conditioner can be cleaned using a special fin cleaner.

3. The compressor overheating protection device is damaged. The compressor's overheat protection device needs to be replaced.

4. The cylinder or coil of the compressor is burned out. A new compressor needs to be replaced.

Air conditioning maintenance.

After the air conditioner is turned on, the maintenance times during the air conditioner start-up process are determined by many factors such as environmental conditions, climatic conditions, number of hours of start-up, surrounding dust, air cleanliness, and whether the room is clean. The environmental conditions are not good, the weather is hot, the air conditioner is outdated, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner start-up process increases, usually once every month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, the air conditioner is turned on reasonably, and the electric fan is used alternately, the maintenance cycle can be appropriately extended, from the start of the air conditioner to the shutdown of the air conditioner for maintenance 1-2 times. Maintenance should be careful and careful, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and refrigeration effect, and achieve energy saving, freshness and comfort.

The air conditioner shows P7 which means outdoor exhaust high temperature protection.

There are two main reasons why the air conditioner appears p7 prompts:

One is that the air conditioner lacks refrigerant.

As a result, the efficiency of cold and hot cycling is insufficient, and the temperature of the external unit rises.

Another reason is that the dust collection of the outdoor unit of the air conditioner leads to poor heat dissipation, which leads to poor heat dissipationThe temperature of the machine is too high.

The solution after the air conditioner appears p71. Put the air conditioner exhaust temperature sensor first.

Unplug so that its temperature is close to the ambient temperature.

2. Multimeter.

The resistance value of the star measurement sensor, determine whether it is a sensor failure or the corresponding electronic control board failure, if it is a state to take the fan, replace the electric control board, and then contact the maintenance personnel to detect whether there is a lack of fluorine, if the air conditioner is deficient in fluoride, then charge fluorine.

1. P7 is a failure of the indoor ambient temperature sensor, or a failure of the communication between the display board and the indoor control board. 2. The air conditioner shows that P7 is generally caused by a lack of fluorine. 3. If the inverter cabinet shows P7, it is caused by the high outdoor exhaust temperature.

Display P7 solution: 1. Check whether the temperature is really too high or there is a problem with the sensor, if the sensor is burned and there is a problem with the skin blindness, replace the sensor, if the sensor has no problem, you should see if it is the system pressure. 2. Check whether the return air pipe is deflated, compare the resistance of the two fans, I am this kind of god and the situation should be replaced with a new return air pipe.

3. If it is a condenser.

If the air conditioner display shows P7 due to being too dirty, you need to clean the condenser or replace the press starter, or change the fan capacitance to a larger one, remove the exhaust pipe temperature, and then put a little refrigerant.

This glitch will also be resolved. 4. Connect the pressure gauge from the maintenance port to check the freon.

Is not sufficient to work properly Freon should be in, refrigerant.

Deficiencies can also lead to such failures. Or check whether the three-phase power supply voltage is too low or too high, and the voltage instability will also lead to this situation.

Dear, hello, I am very staring at Lu Xing to answer for you: What does it mean that Midea air conditioner appears P6? Answer: Midea's variable air conditioner screen appears P6 indicates:

The position protection of the DC inverter compressor, and the temperature thermistor of the outdoor ring Kaicha environment is abnormal. The reason why the air conditioner displays P6: the set temperature is too high, and the set temperature in the room will be reached for a while, so the external unit is shut down, and the air conditioner is left with the internal unit blowing, so it doesn't feel cold.

The temperature in the room rises, and the air conditioner starts so it is cold, so it is recommended to turn the temperature lower. 2.It may be that the external unit is too dirty and the heat dissipation is not good, so the compressor will overheat after working for a period of time, and then work after it is cold.

It is recommended to see if the external unit is too dirty, and if it is dirty, rinse it with clean water.

If the air conditioner P6 appears, it means that the air conditioner inverter module is faulty. It may be that after the air conditioner is turned on, the large current of the air conditioner instantly impacts the inverter module of the air conditioner, which triggers the position protection of the DC inverter compressor of the air conditioner, resulting in the P6 fault code of the air conditioner. In this case, you can turn off the air conditioner, disconnect the power to the air conditioner, and then turn it on again.

Here's the specific introduction: For Oaks air conditioners.

If there is a P6 failure, it could be the following:1The outdoor unit is installed indoors without ventilation or indoors, resulting in poor heat dissipation of the outdoor unit.

It is recommended to move the outdoor unit again and adjust its position to ensure that the outdoor unit can dissipate heat normally. 2.Dust accumulates in the outdoor unit or outdoor unit condenser.

Special fin cleaners can be used to clean air conditioning condensers.

3.Compressor overheat protection device is damaged. The compressor's overheat protection needs to be replaced.

4.The cylinder or coil of the compressor burns out. A new compressor is needed.

For Midea's variant air conditioning screen, P6 means that the position of the DC inverter compression shaker is protected, and the outdoor ambient temperature thermistor.

Abnormal. 1.It may be that the set temperature is too high, the indoor temperature reaches the set temperature, and the eggplant and bend cause the outside to shut down.

It is recommended to lower the temperature. 2.It may be that there is dirt on the external unit, abnormal heat dissipation, and compressor overheating protection.

It is recommended to remove dirt from the outside of the machine. Shed pie.

P6 is the position protection of the DC inverter compressor, it is recommended to shut down and wait for 5-10 minutes before restarting. Turn off the power of the air conditioner and turn it back on. If it still doesn't work, you can find a professional maintenance hermit to repair it.

The P6 display is due to the instantaneous impact of the large current on the frequency conversion module and the residual hall causes the frequency conversion module display failure, and the fixed speed hang-up and destruction machine shows that P6 is a zero-crossing detection fault; Under normal circumstances, it is sufficient to completely power off the unit, and then power on and restore it.
