Haier air conditioner shows e9, Haier air conditioner shows e

Air conditioning in Haier.

According to the internal information of after-sales service, "E9" indicates a high-load protection failure, which is the normal overload protection of the air conditioner, not the fault problem of the air conditioner.

Solution: 1. After the air conditioner is powered off again, wait for a while and then power on the test machine, lower the set temperature, increase the wind speed of the indoor unit, increase the heat exchange of the indoor unit, reduce the power consumption of the air conditioner, and achieve the maximum energy-saving effect of the air conditioner.

2. If it still does not improve, you can call Haier's after-sales service** and ask the service personnel to come to the door for maintenance.

Disconnect the main power supply of the air conditioner and turn it on after 5 minutes, if that's fine, or just occasionally, it might be a voltage problem.

If your air conditioner is hang-up, E9 means that the refrigeration system is faulty, and E9 is a large current protection shutdown, which causes the high current to cause the power supply voltage to be too low, the outdoor unit filter screen is rising, and the capacitance capacity of the external fan is smaller, which may make the current larger.

This is generally due to the communication failure of the indoor unit and the outdoor unit. Workaround:

1. Check whether the communication line is short-circuited or broken.

2. Check whether the thermal sensor of the internal machine is faulty, and the sensor failure will not send the correct working signal.

Haier air conditioning. E9** indicates a high-load protection failure, which is the normal overload protection of the air conditioner, not the fault of the air conditioner.

Solution: After the air conditioner is powered off again, wait for a while and then power on the test machine, lower the set temperature, increase the wind speed of the indoor unit, increase the heat exchange of the indoor unit, reduce the power consumption of the air conditioner, and achieve the maximum energy-saving effect of the air conditioner.

In heating mode, the outdoor machine will frost due to low temperatures, affecting the heating capacity. At this time, the air compressor will automatically enter the defrost mode, and the temperature of the indoor coil will be reduced. In order to prevent cold air from blowing out, the indoor fan will also stop running and display **e9, which means that the air conditioner is currently in the defrosting phase and the internal fan stops supplying air.

To prevent cold air, the E9 display disappears after defrosting.

1.If the air conditioner shows E9, it means that the air conditioner is in the defrosting state at this time, which is not actually a fault. Because the temperature of the outdoor unit is too low, it will lead to frost, which is generally more common in winter, which will affect the heating effect.

2.At this time, the air conditioner compressor will automatically enter the defrost mode, mainly to prevent the cold air from blowing out, the indoor heating will stop, the fan will stop rotating, and the E9** will be displayed on the LCD screen.

3.After the defrosting work is over, it will automatically switch to heating mode, the E9 on the LCD screen will automatically eliminate, and the fan will gradually turn.

You are very close to the front hall, I am happy to answer for you, Haier**Air conditioner E9 is a fault**, mainly manifested in the air conditioner does not work, does not start, etc. Solution: 1. Whether the AC contactor of the outdoor unit is in poor contact with the base or the coil is open or short-circuited.

2. Whether the air switch (leakage switch) of the main power supply of the air conditioner has tripped or been damaged. 3. Check whether the 380V power cord is connected incorrectly. 4. Check whether the three-phase electricity is inverted.

5. Check whether the external compressor is damaged. 6. Check whether the phase sequence detection circuit (outdoor unit motherboard) is out of order or damaged.

1. In the heating operation mode, the outdoor machine will frost due to low temperature, which will affect the heating production, at this time, the air compressor will automatically enter the defrost mode, the temperature of the indoor coil will be reduced, in order to prevent cold air from blowing, the indoor fan will also stop running, and display **E9, indicating that the air conditioner is currently in the defrosting stage, and the internal fan will stop supplying air, in order to prevent cold air, when the defrosting is over, the E9 display will disappear.

2. If the temperature of the indoor coil unit has been reached, the fan will fail if it does not rotate. In addition to the fan failure, the most likely reason is that the room Qichun and the inner coil sensor have an open-circuit fault, which makes the CPU misjudge the temperature too low and has been in a state of cold wind. Another reason is that the coil is quietly staring at the temperature but does not rise, and the refrigeration system fails.

Haier's household air conditioner displays E9 indicating that the high load protection fault rises to the wild, and the air conditioner is normally overload protected. In this case, it is recommended to turn off the power supply of the air conditioner for three minutes and then restart it, turn the set temperature down, and increase the wind speed of the noisy shouting machine in the room. If e9 is still displayed, you can contact Haier customer service.

Summary. **E9 indicates high load protection failure, air conditioner normal overload protection. It is recommended to turn off the air conditioner again and then power on the test machine, lower the set temperature, increase the wind speed of the indoor unit, and increase the heat exchange of the indoor unit, so that the load on the air conditioner will be reduced.

Haier air conditioner display fault**E9, how to deal with it?

**E9 indicates high load protection failure, air conditioner normal overload protection. It is recommended to turn off the air conditioner again after the power is turned on, and the set temperature will be lowered in Jizhou, and the wind speed of the indoor unit will be increased, so as to increase the heat exchange of the indoor unit, so that the load on the air conditioner will be reduced.

I'm Haier air conditioner to treat cold Mo is the same?

Well, yes. The power was cut off a few days ago, and today it was just turned on and turned for ten minutes.

Don't lower the temperature all at once, let the machine run for a while, and it takes a process for the compressor to start.

After a while, the e9 will appear.

You need to contact after-sales, the voltage is unstable, or the capacitor is a problem.

I'm Haier small ** air conditioner.

Thank you. You're welcome, be sure not to get it yourself, pay attention to safety, after all, it's something electrified.
