Why does Gree air conditioner E1 fail, what is the fault of Gree air conditioner e1 and how to solve

E1 is the fault signal, E1: Compressor high pressure protection. If the compressor current is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected, the overload protector should be checked for disconnection and whether the compressor temperature bag is short-circuited.

The method of excluding Gree E1 is as follows:

1. Determine whether the air conditioner fails after running for a period of time or fails when it is turned on, so as to distinguish whether it is a system fault or a circuit fault.

2. System failure: the newly installed machine is not emptied, over-flushed, and the maintenance has not been processed in place 3. Circuit: short-circuit the OVC and zero line of the motherboard of the internal machine, if the failure continues, the motherboard is defective, and it can be replaced or repaired.

E1 1. There is an obstacle in front of the condenser.

2. The control loop is constant.

3. Three-phase power supply is out of phase.

3. Start refrigeration when the outdoor ambient temperature is higher than 43 degrees.

4. The working current is over-the-top and the protector action or the high-pressure pipe pressure is over-the-top and the high-voltage switch is action.

First of all, determine whether the air conditioner has failed after running for a period of time or has failed when it is turned on, so as to distinguish whether it is a system failure or a circuit failure, and the main considerations in the system are:

1 Empty and clean new installation.

2 Excessive flushing repaired.

3 Poor ventilation due to high temperature of the outdoor machine? Dirty? Harsh environment?

Circuit: short circuit internal machine motherboard OVC and zero line, if the failure continues, the motherboard defective replacement, repair, if there is no failure, check whether the high-voltage switch is on the switch under normal pressure should be on, such as on, check the high-voltage switch and OVC connection, if not, repair the high-voltage switch First determine whether the air conditioner is running for a period of time or fail, in order to distinguish whether it is a system failure or a circuit failure, the main considerations of the system: 1 Emptying is not clean New installation 2 Excessive flushing Repair 3 external machine.

High temperature and poor ventilation? Dirty? Harsh environment?

Circuit: short circuit internal computer motherboard OVC and neutral line, if the failure continues, the motherboard is badly replaced, repaired, if there is no failure, check whether the high-voltage switch is turned on under normal pressure switch should be on, such as on, check the high-voltage switch and OVC connection, if not, repair the high-voltage switch

It could be a quality issue.

Gree air conditioner. Display E1 refers to compressor high pressure protection because of the air conditioning compressor.

The current is too large, so the compressor becomes too hot, the temperature of the air conditioner exhaust is too high, the module protection is activated, the air conditioner cannot work normally, the fault light flashes alarm, and the panel shows E1 fault. Solution to E1: 1. When the air conditioner has E1 failure, first check whether the connecting wire of the indoor unit of the air conditioner is broken, if the connecting line is normal, it may be that the circuit board is damaged and the relevant components need to be replaced.

2. Check the air conditioner sensor, whether the air conditioner body line group is broken or broken, and replace it if there is. Popular science knowledge: 1. It is necessary to determine whether it is a failure when it is turned on, or a fault in the operation of the air conditioner, and distinguish whether it is a system failure or a circuit failure.

Check whether the air conditioner overload protector is disconnected and whether the temperature sensor package of the air conditioner compressor is short-circuited, and replace it if so. 2. It may be used in the long fiber period, there is too much scale and there is no cleaning, at this time, the hot water outlet is obviously much smaller than the cold water output, you need to clean and descale immediately, you can buy a set of fast water heater free descaling machine, use it to inject descaling agent into the water heater to clean the water heater and hot water pipeline, the operation is very simple, and it can also be used for regular cleaning in the future, which can be used to avoid such problems again. When the air conditioner fails, it is recommended to contact the after-sales maintenance personnel for on-site maintenance, and do not disassemble and inspect it yourself.

The air conditioner shows E1, which indicates a compressor high-pressure protection failure. There may be a problem with the compressor, and you need to contact a professional maintenance master to repair the compressor; The air conditioner is not cleaned regularly, and the air conditioner needs to be cleaned regularly; The blades of the air conditioner are clogged by something, and the clogged blades need to be removed.

The specific processing method is as follows:

First, there may be a problem with the compressor, such as the compressor stuck, not getting enough refrigeration oil, or the coil structure of the compressor working normally is aging, resulting in the compressor not being able to continue to work normally. Contact a professional maintenance master to repair the compressor or refuel the compressor.

Second, it is possible that the air conditioner is not cleaned regularly, resulting in the accumulation of dirt in the refrigeration transmission pipe in the refrigeration system inside the air conditioner, and finally the compressor exhaust temperature rises to overheat. In this case, it is necessary to clean the air conditioner regularly.

Third, it may be that the blades of the air conditioner are blocked by something, and the air conditioner cannot normally discharge the hot air through the rotation of the blades, resulting in the high-pressure exhaust temperature barrier of the outdoor unit. You need to contact the maintenance master to remove the clogged blades.

Fourth, it is also possible that the air conditioning fan blades are damaged, resulting in the air conditioning wind is relatively weak, and the compressor heat cannot be dissipated to the outside world normally. You need to contact the maintenance master to replace the fan blades so that the air conditioner can work normally.

The failure of the Gree air conditioner E1 is usually caused by the reason of beating down with pants:

1.Indoor and outdoor unit communication failure: It may be caused by communication line failure, communication board failure, etc.

2.Faulty indoor temperature sensor: The delay may be caused by a damaged sensor or poor connection.

3.Outdoor ambient temperature is too low: When the outdoor temperature is lower than the minimum working temperature of the air conditioner, the air conditioner will automatically shut down and display an E1 fault.

4.The power supply voltage of indoor and outdoor units is unstable: it may be caused by the failure of the power supply line Hu Danxiang and the failure of the power board.

5.Other faults: such as indoor and outdoor fan failure, compressor failure, etc.

1. The phase sequence current of the outdoor unit causes the protection circuit board to be broken.

2. Too much freon is added to cause the high-voltage protector to be disconnected.

3. The outdoor fan is broken, and the fan of the air conditioner does not rotate, resulting in the disconnection of the protector.

4. The outdoor unit accumulates too much dust and is too dirty, resulting in overheating protection of the air conditioner.

5. The machine has been used for too long, there is refrigerant leakage inside the refrigeration system, and the refrigerant or compressor has been replaced after treatment is not paid attention to, and the foreign matter enters the refrigeration system, which causes capillary blockage and cannot achieve throttling, cooling and pressure reduction. As a result, the high pressure of the air conditioner is too high, the low pressure is too low, and the pressure protector is disconnected.

1. What is the fault of Gree air conditioner E1?

1. When E1** is displayed on the air conditioner, it may be that there is a communication problem between the indoor unit and the outdoor unit.

2. It is also possible that the compressor current is too large and the exhaust temperature is high, which makes the temperature sensor package short-circuit and e1** appears.

3. When there is an obstruction in front of the condenser of the air conditioner and the control loop is abnormal, the air conditioner will also appear E1**.

2. How to solve the Gree air conditioner E1 failure.

Causes: When the air conditioner compressor fails, the refrigeration oil inside the compressor is not enough, the coil is aging, etc.

Solution: The refrigeration oil can be replaced in time, or the compressor can be replaced directly.

Cause: The refrigeration system of the air conditioner is clogged with stains, causing the pressure to be too high, causing the exhaust temperature of the air conditioner compressor to rise.

Solution: Clean the refrigeration system regularly, replace the refrigerant and filter capillaries.

Reason: The heat dissipation fins of the air conditioner are clogged with dirt, and the heat dissipation effect of the outdoor unit is poor, resulting in the high pressure exhaust temperature being too high.

Solution: Clean the fins with a special fin cleaner.

Cause: When the air volume of the air conditioner is small and the fan is damaged, the temperature of the air conditioner compressor becomes higher when it is discharged.

Solution: You can replace it with a new capacitor, fan blade, etc.

Reason: The high-voltage protection device is broken.

Solution: Replace or short-circuit with high-voltage protection wire.

Cause: The exhaust temperature switch of the compressor is broken, resulting in an open circuit state of the air conditioner.

Solution: You can choose to replace or short-circuit the solution.

3. Gree air conditioner E1 troubleshooting:

1. Gree air conditioner shows air conditioning failure**E1 may be a communication fault between the indoor unit and the outdoor unit;

2. If there is an air conditioning failure**E1, it means that the compressor current is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected, the overload protector should be checked whether it is disconnected and whether the compressor temperature bag is short-circuited;

3. You can open the indoor case 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 bad, and if it is not flashing, the inner board is bad. This is because the indoor unit only receives the pulse signal sent by the external unit when the green light is on, and at the same time sends a signal to the indoor unit, and the indoor and outdoor units communicate;

4. It may also be due to an obstacle in front of the condenser, refrigeration starts when the outdoor ambient temperature is higher than 43 degrees, the control loop is abnormal, and the pressure of the high-pressure pipe is too much and the high-pressure switch is blocked.
