Panasonic inverter air conditioner turns on the heating and the internal fan does not rotate, and it

If it is just turned on for heating, the fan in the air conditioner does not turn, it is normal, because at the beginning of the air conditioner is cool breeze, generally about a minute, and the air in the air conditioner is heated, the internal fan will turn, so that the air conditioner blows out is hot air.

As for freezing, it should be that the indoor air humidity is relatively high, and the temperature is relatively low, which leads to the appearance of icing.

The four-way valve is not connected, when you adjust the heating, the indoor fan will only turn when the induction temperature reaches a certain value (about 30 degrees), otherwise it will blow out cold air. Almost all air conditioners will turn on the fan after two minutes of heating mode. The internal machine is icing, which means that the four-way valve is not connected or does not work, so the refrigerant is running in a normal refrigeration way, so the internal machine will freeze (under normal circumstances, it will not freeze, because the internal fan will rotate and blow the cold air into the room, but you adjust the heating, and the temperature sensing cannot sense the corresponding temperature, the internal fan will not rotate, so the internal machine will freeze).

- Panasonic air conditioner malfunctioned? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner fails, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

If you still don't understand, it is recommended that you go to the [Air Conditioning Fault **Net] basic knowledge area and take a look at the maintenance cases to get started.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish you all the best in your work, fix the air conditioner as soon as possible, and live happily ———

Find after-sales service, it is estimated that the refrigerant is leaking or missing!

If it's refrigeration, then the air conditioning is problematic. If it is heating, the internal fan will not run at the moment of start-up, and the internal fan will only run after the external unit heats up the internal evaporator.

And any household air conditioner has this phenomenon, this phenomenon is called anti-cold air function. If the internal evaporator is not hot, the air blown by the fan is cold air instead of hot air. Therefore, household air conditioners are designed to prevent cold air.

If there is no refrigerant in the refrigeration system of the air conditioner, and the evaporator of the internal unit will not be hot for how long the external unit runs, then the internal fan will start to run in about 5-10 minutes.

After the internal fan is running, the wind blowing out is very small, and this wind speed is not adjustable. If this happens, it means that the air conditioning refrigerant is not available or the compressor is not running.

In this case, the only way to find a professional master is to add refrigerant or supplement refrigerant. At present, there are only three types of refrigerant for air conditioners in China, namely: R410A, R22 and R32.

These three types of smart machines cannot be mixed, and which type of refrigerator must be added with which refrigerant.

The nameplate of the outdoor unit of the air conditioner indicates the type of refrigerant and the amount of refrigerant to be filled. When filling the refrigerant, it must be filled in strict accordance with the amount and refrigerant model marked on the nameplate of the external machine.

The possible situation is as follows, lack of freon, broken tube temperature sensor, broken fan and circuit board.

Household air conditioners have a logic to prevent cold air from blowing in the heating mode, that is, the fan does not rotate when the indoor coil temperature is lower than a certain value, so in the heating mode, when the outdoor unit is working when it is just turned on, the indoor fan does not rotate, and after a period of time (different air conditioners have different times under the same outdoor temperature conditions), the indoor temperature rises before the fan turns.

If your air conditioner's indoor fan does not turn while heating, there may be a number of reasons:

The sensor for indoor coil temperature detection is loose or the temperature measurement is inaccurate.

The system is not having enough refrigerant.

Are you in the north? What is the ambient temperature like now "Outdoor"?

There is also indoor control defrosting or outdoor motherboard defrosting "home machine for the inner motherboard".

Defrost runs. Defrost the condenser sensor.

Defrost entry conditions: Defrost can be entered if any of the following conditions are met.

1.T3<0 for 50 minutes and T3<-3 for 1 minute. (T3 is the temperature of the external condenser) This value is inconsistent according to different manufacturers (similar to the same).

2.From the end of the latest defrosting, only the outdoor fan was turned off and the compressor was not turned off for a total of 90 minutes in the evaporator high temperature protection.

Note: When the defrost is over or T3 20 is restarted, the whole shutdown or mode change counter is not cleared.

Defrosting end conditions: When any of the following conditions are met, the defrosting is terminated and the defrosting is transferred to general heating.

1.The defrosting time reaches the required 10 minutes; Defrosting Action:

2.The indoor fan turns to a light breeze (low air) after the compressor is stopped and continues to run for 15 seconds and then shuts down;

2.After stopping the defrosting, it is transferred to normal heating operation, (the indoor fan is started with the set wind at T2 42,) the function after starting is operated according to the cold wind condition.

Summary: Is 1 a cold-proof state? Mistaken for defrosting. "Defrosting Procedure Up".

2. Please check whether the outdoor heat exchange effect is ideal for the external fan! Is the installation environment ventilated?

If it is the first item. then the fault is reconfirmed.

Air conditioning manufacturers usually have anti-cold air when heating, that is, when heating, the external unit starts first, and the internal unit waits until the pipe is hot.

If you don't move, you can consider whether there is a problem.

It may be that the external unit is broken, and you can repair it.

Check the external fan power supply or relay signal line, and then check the capacitor motor.

Heating starts immediately Indicates that the cold air failure Check the temperature of the inner machine tube Check the capacitance of the external fan.

The preheating time of the air conditioner is 30 minutes, and the indoor fan does not rotate for 20 minutes, because the preheating time has not yet been reached. Just be patient.

The fan you said refers to the inside or outside, no matter which fan, in the air conditioning refrigeration or heating, must be turned, about the air conditioning you said can not be heated, but can be cooled, I judge that it may be in the four-way valve this problem,

1. The refrigeration is not enough, and the machine will turn after a while. 2. If the fan is not refrigerated, it will not rotate.
