What is the fault of the air conditioner showing E1, and how to solve the fault E1 displayed on the

1.If the air conditioner has an E1 fault code, it may be that the compressor current is too large and the air conditioner start protection is not in place, or it may be that the compressor is overheated and the air conditioner start protection is not in place. 2.

If the E1 fault code occurs in the air conditioner, it may also be that the exhaust air temperature of the outdoor unit is too high, the air conditioner starts protection, or the phase sequence current protection circuit board of the outdoor unit is damaged. This phenomenon cannot be solved by restarting the air conditioner after a power outage. Appears in the air conditioner.

If it is because the compressor cylinder is stuck or the refrigeration oil is insufficient, you can add enough refrigeration oil to the air conditioner. After refueling, restart the air conditioner and it will return to normal. If the compressor is damaged, it needs to be replaced.

It appears in the air conditioner, probably because the refrigeration mechanism is blocked, the branch pipe is blocked, which will increase the pressure and increase the compressor exhaust temperature. When the compressor overheats, it will stop the protection. You can clean the system.

If the branch pipe is clogged, the pipe needs to be cleaned or replaced. Appearing in the air conditioner, it may be because the heat sink of the outdoor unit of the air conditioner is blocked, the heat sink cannot work properly, the heat of the outdoor unit cannot be discharged, and the outdoor unit is overheated, which will also protect the shutdown. You can clean your fins with a fin cleaner.

In the air conditioner, it may be because the air fan blades are damaged and cannot work normally, so that the heat of the compressor cannot be dissipated normally, and the temperature is too high to shut down for protection. Broken blades need to be replaced.

Hello, the air conditioner shows that E1 is a compressor high pressure protection, common reasons:

1. It may be that the compressor is faulty, the compressor is stuck or the refrigeration oil is insufficient. Replace the refrigeration oil or directly replace the air conditioning compressor;

2. It may also be that the heat dissipation fins are dirty and blocked, and the high-pressure exhaust temperature is too high due to poor outdoor heat dissipation. Clean the fins with a special fin cleaner;

3. When the compressor exhaust temperature switch is damaged, the measurement is not working, and the open circuit is open, E1 failure may also occur, and the line may be replaced or shorted;

4. When the air volume is small, the fan is damaged, and the capacity of the fan starting capacitor is insufficient, it will also cause the compressor exhaust temperature to be too high and cause protection. It can be repaired by replacing capacitors, fan capacitors, fan blades, etc.

Fault **e1 description Compressor current is too large, compressor overheating, exhaust temperature is high, module protection, should check whether the overload protector is disconnected and whether the compressor temperature sensor is short-circuited.

Open the indoor chassis to observe whether the green indicator light on the circuit board of the indoor unit is shining, if it is shining, the outer board is broken, and if it is not, the inner board is bad. This is because the green light will only turn on when the indoor unit receives the pulse signal sent by the external unit, and at the same time send a signal to the indoor unit, and the indoor and outdoor units communicate.

The air conditioner shows E1, what to do.

No matter how good the air conditioner is, if the service life is too long, there will be some failures, such as E1 failure, compressor high-pressure protection. Those who don't understand the failure of the air conditioner may not know how to repair it. This section describes how to overhaul the E1.

1. The problem of compressor, if the compressor is stuck, does not get enough refrigeration oil or the compressor working coil structure is aging, it will lead to the compression failure to work normally and E1. If the refrigeration oil is missing, you can add refrigeration oil, and if the compressor is damaged, it is recommended to replace it with a new one.

2. If it is because the refrigeration tissue is blocked by dirt. Check whether the branch pipe is blocked, causing the locking pressure to be too high, and the compressor exhaust temperature rises to overheat protection and stops. Treatment: Clean the system, unclog or replace the filter capillary.

3. If the fins of the outdoor unit of the air conditioner are blocked by stolen objects and cannot operate normally, the heat of the outdoor unit cannot be discharged, resulting in the high-pressure exhaust temperature and protection of the outdoor unit. Solution: To clean the fins of the outdoor unit, it is recommended to use a special fin cleaning agent.

Gree air conditioner failure**E1 is the system high voltage protection.

Generally, the possibility of this problem is: line problem, motherboard problem, and protector itself problem.

What you need to do is to check the line, whether the connection line between the internal and external machine is broken, and whether there is a grounding wire, and whether the pipeline has been added, the copper pipe has been added, and the line should be added at the same time as the pipe, and then see whether the power line and the signal line are connected.

Then check whether it is a motherboard problem, whether it is a leakage of the host, you need to check the line first and then check the compressor, if the compressor can only be replaced. In addition, there is also whether the outdoor unit dissipates heat, whether the heat dissipation of the external unit is ideal, whether it is caused by the dirty filter screen of the internal and external machine, that is, the condenser is dirty, if the filter screen and condenser are discharged, it is necessary to see if it is caused by the refrigerant, that is, to check whether the fluorine is too much or too little, if not, then it is the problem of the protector itself. It may be that the current is too large instantaneously, resulting in the action of the protector or the pressure of the high-pressure pipe, resulting in high-voltage protection.

Simply say to read the manual, the general manual has a fault ** and the content of the representation and the solution! If you really can't understand or can't find it, it is recommended that you find after-sales service!

It is generally a problem with the temperature sensor, check whether the sensor probe is in poor contact.

**What is the reason for the display of e 1 on the motor control panel of the water air conditioner?

Three Ace Fixed Frequency Air Conditioners show what is wrong with E1.

The room temperature sensor of the unit in E1 is faulty.

It's OK to pick it up.

It means that the high-voltage protection caused by the communication between the indoor unit and the outdoor unit is faulty.

E1 is the fault of the air conditioner** (compressor overcurrent protection, compressor overheating protection, outdoor unit exhaust temperature too high protection, outdoor unit phase sequence current protection circuit board is broken).

The reasons for the failure are as follows:

1. Freon multi-cause the action (disconnection) of the high-voltage protector.

2. The machine has been used for too long, there is a leakage inside the refrigeration system, and the refrigerant is often added or the compressor is replaced after treatment, and the dirt enters the refrigeration system and causes capillary blockage, which can not achieve throttling, cooling and pressure reduction. Pour until the high pressure of the air conditioner is too high, the low pressure is too low, and the pressure protector is activated (disconnected).

3. The outdoor fan is broken (note: the capacitance of the fan is broken, and the fan does not move), does not rotate, and pours to the protector action (disconnection).

4. The phase sequence current protection circuit board of the outdoor unit is broken.

5. The outdoor condenser accumulates too much dust and dirt, which leads to overheating protection of the air conditioner.

Treatment: It is necessary to clean the condenser of the outdoor unit of the air conditioner, and it is recommended to find a professional to clean it.

Air conditioner display E1 is what is the fault Hello dear, happy to answer for you.

1. What does air conditioner E1 mean 1. The air conditioner has an E1 failure**, which may be because the compressor current is too large, and the air conditioner starts protection, or it may be because the compressor is overheated, and the air conditioner starts the protection program. 2. If the air conditioner has an E1 fault**, it may also be because the exhaust temperature of the outdoor unit is too high, the air conditioner starts protection, or the phase sequence current protection circuit board of the outdoor unit is damaged. This phenomenon cannot be solved by restarting the air conditioner by powering off.

2. What is the fault of the air conditioner E1 and how to solve it 1. If the air conditioner appears E1, if it is because the compressor is stuck or there is not enough refrigeration oil, you can add enough refrigeration oil to the air conditioner, and after adding, restart the air conditioner, and it can return to normal. If the compressor is damaged, the compressor needs to be replaced. 2. The appearance of E1 in the air conditioner may be because the refrigeration organization is blocked, and the branch pipeline is blocked, the pressure will increase, the exhaust temperature of the compressor will rise, and the compressor will be shut down for protection when the compressor is overheated.

The system can be cleaned and if the branch pipe is clogged, the pipe needs to be cleaned or replaced. 3. The appearance of E1 in the air conditioner may be because the fins of the outdoor unit of the air conditioner are blocked, the fins cannot work normally, the heat of the outdoor unit cannot be discharged, and the temperature of the outdoor unit is overheated, which will also protect the shutdown. The fins can be cleaned with a fin cleaner.

4. The air conditioner appears E1, which may be due to damage to the empty fan blades and cannot work normally, and the heat of the compressor cannot be dissipated normally, and the temperature is too high, and it will be shut down for protection. Broken blades need to be replaced.

How to solve the fault E1 displayed on the air conditioner.

Reasons: 1. Leakage protection of external aircraft. Inspect the circuit system and repair the damaged circuit.

2. Excessive freon filling causes the high voltage protector to be disconnected. Release some freon.

3. If the outdoor fan is broken and the air conditioner has no heat dissipation capacity, it will enter the E1 shutdown state and replace the fan motor. Household air conditioners are usually turned off in September and turned on in May or June of the following year, which is more than half a year. Therefore, before turning on the air conditioner, be sure to do a comprehensive "diagnosis" to check whether the air conditioning equipment is "faulty".

According to the results of the inventory, under the guidance of professional and technical personnel, do a good job of maintenance and cleaning. This maintenance and cleaning should be in place, including the housing, body and filter of the outdoor and indoor units, and then start the trial run to observe the refrigeration rate and effect.

What is the reason for the failure of Burrese air conditioner E1,71?

There should be corresponding instructions on the manual, and it is recommended to refer to the manual to solve the brand after-sales consultation.

TECO**Air Conditioning Failure**E1

01 Condenser Obstacle: Due to poor heat dissipation, the air conditioner appears E1. It is necessary to observe the ventilation and heat dissipation of the outdoor unit, as well as whether the environment used by the air conditioner is caused by excessive dust and oil smoke pollution.

If yes, what can you use to clean the radiator outside. If the floor is too high, it is necessary for a professional to repair the technical fault (abnormal loop control): check whether the signal connection of the outdoor unit is normal.

The air conditioner is basically a heating and cooling air conditioner and needs to be repaired. 03 three-phase power supply phase: it is caused by the change of indoor power supply in the later stage, so friends who are decorating or modifying the house should pay attention to the air conditioning power supply system, otherwise the three-phase power supply will be very troublesome system high-voltage protection, fault ** E1 line problem:

Check that the connection between the inside and outside of the machine is not interrupted, that the underground cables are connected, that the pipes are added (add copper pipes, addwire), and that the power cables and signal cables are connected correctly. 05 Motherboard problem: whether the host is leaking, check the circuit first and then check the compressor, if so, then you need to replace the new skin pressing and positive shrinking machine.

Check if there is too much or too little fluorine, and consider the problem of fluoride. If not, it's a matter of the protection itself. It may be that the current is too large for a while, resulting in overvoltage or excessive pressure in the high-pressure pipeline, resulting in high-voltage protection.

06 Cooling starts when the outdoor temperature is higher than 43: It is generally caused by damage or malfunction of indoor and outdoor temperature sensors. It is recommended to replace the original air conditioner temperature sensor.
