Why can t I turn on the electric auxiliary heat of my 4 HP Gree inverter air conditioner, and there

1. Do not pay attention to maintenance.

The filter in the air conditioner accumulates too much dust, blocking the circulation of air, making the heat unable to output in time, resulting in insufficient heating, which will make people feel that the heating effect of the air conditioner is not good or even no heating. This situation is easy to solve, you only need to remove the filter, wash it with clean water, dry it in a ventilated place and then install it back on the air conditioner. Do not use laundry detergent.

Detergent such as detergent should be cleaned, and the filter should not be dried on an open flame. In addition, users should maintain a good habit of cleaning the air conditioner filter regularly, generally once a month.

Second, the outdoor temperature is too low.

The lower the outdoor temperature, the more electricity the air conditioner needs to consume to defrost, the power attenuation is large, and the heating effect is not ideal. In this case, you can use a tool to artificially remove the frost from the outdoor unit of the air conditioner to help the air conditioner defrost quickly. If you have a water system in your home** air conditioner, you can also use it with a wall-hung stove.

The linkage can not only assist the outdoor defrosting of the air conditioner, improve the heating efficiency of the air conditioner, but also provide domestic hot water at the same time, killing two birds with one stone.

3. Lack of freon.

Nowadays, most air conditioners are heat pump type or heat pump plus auxiliary electric heating type, and the heating of these two air conditioners is to use freon evaporation to absorb heat from the outside air. If there is a lack of fluorine, it will not be able to absorb heat, and the air conditioner will not be able to heat. In this case, you need to contact a professional to come to your home for fluoride.

These are just a few of the main reasons why air conditioners don't heat. If the above three methods fail to solve the trouble of the air conditioner not heating in your home, it may be that the air conditioner is out of order, and you need to contact the after-sales personnel for door-to-door service. Although the current air conditioner is generally summer and winter.

Dual-purpose, but the specialty of the air conditioner is still manifested in refrigeration, even if it works normally, the heating is not comfortable enough. If possible, it is recommended to use underfloor heating or radiators.

way of heating.

1. Remote control:

1. The screen appears garbled or frozen. Press the reset button to disarm, or the battery is low.

2. The temperature is not displayed. In air supply or automatic mode, the remote control does not display the temperature.

3. If the receiving head is broken or cannot work normally due to moisture, check the transmission of the remote control signal. Use a digital camera (mobile phone is also available) to point at the transmitter port of the remote control, and press any button on the remote control to see if there is an infrared signal emitted.

4. The remote control mode is incorrect, or the temperature setting does not meet the boot conditions. When cooling, the set temperature should be less than the indoor temperature, and when heating, the set temperature should be greater than the indoor temperature.

5. The battery of the remote control is low, which will cause the remote control distance to be short or unable to be remotely controlled. It is recommended to remove the remote control battery when the Gree air conditioner is not in use, and reinstall or replace it when in use.

2. Power supply voltage:

1. The power supply is not connected or out of power, the power conductor socket is not in good contact, or the power conductor wire diameter is thin or aging.

2. The power supply voltage is low. Fixed frequency Gree air conditioner starting voltage: 187V, voltage fluctuation range:

198-242V, the starting voltage of the inverter Gree air conditioner: 156V, the voltage fluctuation range: 176-264V, it is recommended to install a voltage regulator at home.

1.It should be related to the environment, and when the outdoor temperature is high, you try, when the outdoor temperature is too low, the air conditioner can not play a heating effect, the auxiliary heat is forced to turn on the program, and you can't blow cold air! If it's not too cold outside, it's an air conditioning problem!

2.The air conditioner does not have this feature, so it does not respond. If so, try turning up the temperature.

4。Limit state: The outside temperature is too low, lower than the minimum outdoor temperature that can be heated by the air conditioner, and only auxiliary heat is operated.

5。When the air conditioner is in the defrosting state, it means that the radiator of the outdoor unit is full of frost, running in reverse, the fan stops, and the compressor works.

6。The air conditioner was broken.

It may be caused by poor key contact, it is recommended to open the remote control shell and wipe the conductive rubber keys with anhydrous alcohol.

If there is no problem with the other buttons, but only the auxiliary power selection button does not respond, you can judge the quality through the mobile phone camera.

The method is to turn on the mobile phone camera, and then press the button of the remote control corresponding to the camera lens, if there is a small red dot flashing, it means that the remote control is good.

If there is no red dot flashing, the remote control is damaged.

If you don't hear a "beep" sound after pressing the key, it means that the remote control does not send a signal, and the fault is that the remote control button is out of order.

If you hear a "beep" sound after pressing the button, it is normal, Gree air conditioner.

The electric auxiliary heating function will automatically shut down when the tube temperature reaches 55. Some models after 2018 are automatically controlled by electric auxiliary heating, which is only controlled by the feedback of the tube temperature sensor in heating mode, which will automatically turn on when the machine is turned on, and automatically turn off when the tube temperature reaches 55 or 65. Gree's full range of air conditioners will automatically turn off when the tube temperature reaches 65, and the manual opening command is still accepted at this time.

When the tube temperature reaches 75, the whole series of Gree air conditioners will be forced to turn off the electric auxiliary heat, and do not accept the manual control command to turn on, some models will simultaneously extinguish the panel "auxiliary heat" indicator, at this time, press the remote control auxiliary heat function will only hear the "tick" sound prompt, but the air conditioner will not make any response.

Check whether the remote control of the air conditioner is out of power or not, replace it in time and try again, the auxiliary heating function needs to wait for a while before heating.

It should be that the remote control button is broken.

Tools to prepare: Gree air conditioner, remote control.

1. Take Gree KFR-35GW (35594) FNHAA-A4 air conditioner as an example, first turn on the switch of the air conditioner.

2. There is a "Dry and Auxiliary Heat" button on the remote control of the air conditioner. Press once to open it, press the second time to turn it off, which is mainly drying. Some will have a secondary heating function.

3. If the electric auxiliary heating function has been turned on, find the "Mode" button first, and you can press the mode of the remote control to select.

4. When you press the mode, when you see a small sun icon, that is, the electric auxiliary heating function is turned on, and then press it to turn on another function, that is, the electric auxiliary heating function has been turned off.

5. Generally, it is in the winter when it is particularly cold to turn on the auxiliary heat, it is best not to open it often, when the air conditioner is heating, the external unit may freeze, and the ice should be melted regularly, and the ice can not be heated.

<> Gree air conditioner. Why can't the auxiliary heat be turned off: it can still be turned off. Press the "On/Off" button once. Then on the remote control of the air conditioner.

, press the "Mode" switch to switch to "Heating Mode". After that, the "heating mode" will be displayed on the remote control of the air conditioner. Then on the remote control of the air conditioner, press the "auxiliary heat" switch. Finally, in the heating mode, turn off the auxiliary heating function.

This answer is applicable to most air conditioner models such as Gree KFR-35GW K(35556)D1-N1 and Gree KFR-35GW (35557)FNDE-A3.

Auxiliary heating is the meaning of auxiliary heating, there is an electric heating wire in the air conditioner can assist the heating of the air conditioner, improve the heating speed and heating effect, use the "dry auxiliary heating" button in the "heating" state can be controlled, it is recommended to open when "heating".

To turn on the electric auxiliary heating function of the Gree air conditioner, you need to press the dry and auxiliary heat button on the air conditioner when the air conditioner is turned on.

In order to improve the heating effect of the air conditioner in cold weather, the heat generated by the heating wire will be blown into the room after being heated by the heating wire, which will increase the air outlet temperature of the air conditioner. The heating efficiency of the air conditioner is greatly improved. Therefore, the temperature of the air conditioner with electric auxiliary heat rises faster.

Secondly, when the temperature is below 0 degrees Celsius, the heating effect of the air conditioner is not good, and after increasing the electric auxiliary heat, the electrical energy is directly converted into heat energy, and it can also be heated at minus a few degrees in winter.

In addition to turning on the electric auxiliary heating function to increase the heating temperature in winter, the following measures can also be taken:

1. The room heats up more rapidly when the warm air blows: the proportion of cold air is heavy, and the proportion of hot air is light. Therefore, the air conditioner heats the air outlet downward, that is, the hot air blows downward!

Doing so will cause the hot air to rise naturally, which will increase the overall temperature in the room, greatly improving thermal efficiency and comfort, and reducing power consumption.

2. Do not switch on and off the air conditioner frequently in a short time: the start of the air conditioner is also accompanied by the synchronous start of the outdoor unit compressor, and every time the compressor is started, a large current is required, and the frequent switching of the air conditioner in a short period of time also means that the compressor is also started repeatedly, which indirectly causes additional power consumption, and may also cause damage to the compressor and affect the service life.

Tool Material: Take Gree KFR-26GW air conditioner remote control as an example.

1. First of all, on the Gree KFR-26GW air conditioner remote control, press the "Run on and off" button.

2. Then on the Gree KFR-26GW air conditioner remote control, press the "Mode" button and set it to "Heating Mode".

3. Then on the remote control of the Gree KFR-26GW air conditioner, the "heating mode" is displayed.

4. Furthermore, on the remote control of the Gree KFR-26GW air conditioner, press the "auxiliary heat" button.

5. Finally, on the remote control of Gree KFR-26GW air conditioner, turn on the electric heating function of Gree KFR-26GW air conditioner.

If there is a special electric auxiliary button on the remote control, pressing it once will turn on the electric auxiliary heating work, and press it again to turn it off.

If it is the old model, there is no special manual switch on the remote control to switch the electric auxiliary heating button, that is, the temperature control circuit of the motherboard detects the temperature difference between the room temperature and the set temperature to automatically control its opening and stopping.

Press the auxiliary heat button on the left side of the remote control, and select the auxiliary heat function to turn off or on.

It is recommended to choose according to the outdoor ambient temperature, when the outdoor ambient temperature is high and the heating effect of the air conditioner is very good, the auxiliary heating function should be turned off, which is also more energy-saving. When the outdoor ambient temperature is very low and the heating effect of the air conditioner is not good, you can turn on the auxiliary heating function to improve the heating effect of the air conditioner, of course, this power consumption is also very large.

Attached: Common sense of air conditioning use:

1. First of all, it is necessary to carry out reasonable maintenance of the air conditioner, keep the inside and outside of the air conditioner body clean and clean, and regularly clean the filter screen and the outdoor fin-shaped aluminum foil heat sink to make the air conditioner in the best working condition and achieve the purpose of saving electricity and prolonging life.

2. The temperature difference between indoor and outdoor should not be adjusted too much, and the best temperature for the human body to feel the environment is between 18-25 degrees. Considering the factor of power saving, when the air conditioner is refrigerated in summer, the higher the indoor temperature is adjusted, the more electricity is saved, and the indoor temperature will increase by 5-8% for every degree lowered, and the general adjustment is between 26-29 degrees, as long as it does not feel hot. It can also be used in conjunction with an electric fan to improve indoor comfort.

In winter, the temperature in the heating room of the air conditioner should not be adjusted too high, and it is advisable to set and adjust it at about 16-22 degrees, the higher the temperature, the greater the power consumption, because the heating consumption of the air conditioner is about twice as large as that of refrigeration.

3. Try to seal the doors and windows of the room, if the sun is directly irradiated, thickened curtains should be installed to improve the sealing and thermal insulation effect of the room.

4. When the air conditioner is working for refrigeration, the wind deflector of the indoor unit should be adjusted to blow the air in the horizontal direction, and the wind speed should also be adjusted to the automatic wind speed, and the air conditioner will automatically adjust the wind speed according to the indoor temperature. If the air conditioner is blowing directly on the bed or person, you can buy a wind deflector online to use it. When the air conditioner heats and heats in winter, it is the opposite, and the air should be adjusted to blow downward, so that the indoor temperature is the most uniform, because the cold air flow is downward, while the hot air flow is upward.

5. In summer, if the outdoor unit is directly exposed to the sun when working, it is best to install a sunshade to improve the heat dissipation effect.
