How to repair Galanz air conditioner E2 fault

- Is the air conditioner malfunctioning? With my 8 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 Conditioning Fault Code Network] to check 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.

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 ———

- If you think it's good, please click on the answer, give a good review, and wish you a better life———

The machine is generally faulty**, you can check it. Or take a look at the instructions.

<> Galanz air conditioner E2 fault indicates anti-freezing protection. If there is frost, there are three possibilities: the system lacks fluorine, the temperature is below 25, and the surface of the evaporator is too dirty, resulting in a small air volume.

It is recommended to add fluoride or clean the filter screen of the indoor unit and the condenser of the outdoor unit in time.

If the evaporator is not frosted, it may be that the position of the indoor tube temperature head is not right, resulting in the local temperature being too low, and the tube temperature head can be moved out to try again. Excluding the above possibilities, it may also be that the indoor tube temperature sensor package is damaged or broken, the display itself is faulty or the control board is problematic, the indoor motor speed is too low, etc., and the corresponding device can be replaced or repaired.

1. The cause of Galanz air conditioner E2 fault code.

Fault content: indoor evaporator antifreeze protection.

Cause of failure: 1. The sensor rental pin is loose or has poor contact.

2. The sensor is damaged and the resistance value is wrong.

3. If the control circuit board fails, there is no good way to receive and send out the control signal.

4. The refrigerant of the evaporator is overcooled, resulting in frosting.

It is recommended to find a professional maintenance personnel to check it.

2. Galanz air conditioner failure**.

E1: If the compressor current is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected, check whether the overload protector is disconnected and whether the compressor temperature sensor package is short-circuited.

E3: Indoor temperature sensing head short circuit or open circuit.

E4: Short circuit or open circuit of the temperature sensing head of the indoor evaporator tube.

e5: Indoor and outdoor communication failure.

F6 or FF 06 indicates a PG motor failure.

F7 or FF 07 indicates a room temperature sensor failure.

F8 or FF 08 indicates a faulty room tube temperature sensor.

F9 or FF 09 indicates a faulty outdoor tube temperature sensor.

3. How to maintain Galanz air conditioner.

1.The main engine of the air conditioner is equipped with a protective cover.

In the season when the air conditioner is not in use, a protective cover should be added to the outdoor unit to prevent damage to the air conditioner unit in bad weather as much as possible. The protective cover material is waterproof and dustproof.

2.In thunderstorms, it is best not to turn on the air conditioner.

At this time, if the air conditioner is in a state of power failure, the possibility of burning the motherboard due to lightning and rain is minimized.

3.Use it frequently in wet weather.

People are afraid of moisture, electronic components are also afraid of moisture, ** air conditioning maintenance because moisture will not only reduce the insulation performance of the parts, but also corrode the parts, causing machine failure. Especially in the rainy season in the eastern coastal areas and southern plum confines, the normally open air conditioner can not only dehumidify the room, maintain the indoor air quality and avoid the dampness of indoor items, but also protect the air conditioner itself from the harm of moisture.

4.Repair in time when the situation is found.

Home ** air conditioner is a system, if there is an abnormal situation during use, please stop immediately, do not wait until a small problem causes a big failure to think of after-sales service.

The meaning of the E2 fault of the air conditioner is anti-freezing protection, and the anti-freezing protection is that when the evaporator temperature is too low, the air conditioner enters a protective state in order to protect itself. Solution: If the evaporator is not frosted, it may be that the position of the indoor tube temperature head is wrong, resulting in the local temperature being too low, and the tube temperature head can be moved out to try again.

Extended: Precautions for the use of air conditioners.

1. Wait about 10 minutes before turning on the air conditioner, first take Peizen to discharge the dirt inside the air conditioner, and then close the window, which can prevent people from absorbing the dirt inside the air conditioner, thus producing respiratory diseases and avoiding adverse effects on our health.

2. If you go out for a long time, we don't need to turn off the air conditioner, many people think that turning off the air conditioner can save energy, stupid dust is actually incorrect, the air conditioner switch is too frequent, not only can not save electricity, but also consume more electricity, because usually the power consumed by the inverter air conditioner to start a chain is about the same as the consumption of running for two hours.

Summary. Fault**: E2 Fault content: Cause of failure of anti-freezing protection of indoor unit evaporator:

The indoor fan does not rotate or the tuyere is blocked.

The indoor ambient temperature is below 18 degrees.

The thermometer head of the tube is broken.
