What are the typical faults of air conditioners?

There are 10 typical faults in air conditioners:

1. There is often the sound of water flowing, or the sound of water boiling.

This is the sound of refrigerant flowing in the air conditioner, even when it stops.

2. There is often a "poof" sound.

This is the switching sound of a change in the direction of refrigerant flow in the air conditioner.

3. When it starts to run or stops running, the outdoor unit has a "click" sound.

This is the sound that the reversing valve makes when it opens or closes.

4. In the refrigeration operation or induction dehumidification operation, the wind blows out in the form of fog.

This is because the hot air in the room is formed when it is blown through by cold air.

5. Blow out the odor from the air conditioner.

This is due to the fact that various flavors in the air (cigarette smoke, cosmetics, food, etc.) are blown out after adhering to a filter that has no special function.

6. Change the running sound of the outdoor unit of the inverter.

This is due to the change in the speed of the compressor according to the change in room temperature.

7. During defrosting, there is steam emitted from the outdoor unit.

This is caused by the melting and evaporation of frost attached to the heat exchanger of the outdoor unit.

8. Even if you press "Stop", the air conditioner will still rotate.

This is due to automatic fresh defrosting (when the heating operation is stopped, the microcomputer device in the unit detects that there is a considerable degree of frost accumulation in the outdoor unit, and it is necessary to automatically remove the defrost command issued by the defrost command).

9. The indoor unit has a small "click" sound.

This is due to the change in the speed of the fan motor of the indoor unit or the sound emitted when the air conditioner itself expands and contracts due to the temperature change.

10. The running light is lit - flashing - lit.

This is due to the protection circuit and preheating sensor when switching from refrigeration to heating during preheating from stop to operation.

No refrigeration, no heating, water leakage, work stops suddenly.

Common fault range of air conditioner 1, air conditioner only blows air and does not refrigerate fault range: outdoor unit does not work; lack of fluoride in air conditioners; Compressor damage; The compressor starter capacitor is damaged. 2. The air conditioner is not turned on, including the portable unit.

3. The air conditioner does not start. 4. The outdoor fan of the air conditioner does not close the beam work. 5. The compressor of the air conditioner does not start.

6. The air conditioner is not cold enough. 7. The air conditioner can be turned on manually and the remote control can not be turned on. 8. The remote control of the air conditioner can be turned on, and the manual can not be turned on the car.

20 common faults of air conditioner 1, air conditioner only blows air and does not refrigerate. Scope of failure: the outdoor unit does not work; lack of fluoride in air conditioners; Compressor damage; The compressor starter capacitor is damaged.

2. The air conditioner does not turn on. 3. The air conditioner does not start. 4. The outdoor fan of the air conditioner does not work.

5. The compressor of the air conditioner does not start. 6. The air conditioner is not cold enough. 7. The air conditioner can be turned on manually and the remote control can not be turned on.

8. The remote control of the air conditioner can be turned on manually, but it cannot be turned on manually.

1.The air conditioner does not cool or does not heat enough: It may be due to insufficient refrigerant, compressor failure, blockage of the radiator of the lead outdoor unit, etc.

2.The air conditioner is noisy: It may be that the fan, compressor, motor and other components of the indoor or outdoor unit are faulty or loose.

3.Air conditioner leakage: It may be that the water tank, water pipes, drainage holes and other parts of the indoor unit or outdoor unit are blocked or damaged.

4.Air conditioner remote control failure: It may be due to the remote control battery is dead, the remote control is damaged, or the indoor unit receiver is malfunctioning.

5.Air conditioner power failure: It may be due to a loose power cord, blown fuse, circuit board failure, etc.

6.Air conditioner odor: It may be that dust, bacteria and other dirt have accumulated on the filter, evaporator, drain pipe and other parts of the indoor or outdoor unit.

7.Insufficient air volume of the air conditioner: It may be that the fan, filter, evaporator and other components of the indoor unit or outdoor unit are blocked or damaged.

8.Automatic shutdown of the air conditioner: It may be due to the temperature sensor failure of the indoor unit or outdoor unit, the failure of the circuit board, etc.

What are the common faults of household air care?

1. Insufficient refrigeration Insufficient refrigeration is one of the common problems in the use of air conditioners.

2. Peculiar smell After the air conditioner has been used for a long time, it is easy to have peculiar smell.

3. The air conditioner does not heat The air conditioner does not heat the wide circle before it is a problem often encountered in winter.

4. Loud noise It is not possible to turn on the air conditioner in summer, but the air conditioner is too noisy and noisy, which also affects the living experience.

5. High air humidity.

6. The air conditioner suddenly stops working.

7. The air conditioner starts slowly.

8. Water leakage.

There are 10 common main faults of air conditioners, namely: poor cooling or heating effect, air conditioner does not start, air conditioner water leakage, air conditioner noise, air conditioner odor, indoor and outdoor unit mismatch, outdoor unit freezing, air conditioner remote control failure, air conditioner circuit failure and air conditioner automatic on/off.

The common major faults of air conditioners are as follows:

1. Poor refrigeration or heating effect: it is generally caused by insufficient refrigerant, blocked filter, and excessive temperature difference between indoor and outdoor.

2. The air conditioner does not start: it is generally caused by power supply problems, remote control failure, fuse blowing, circuit board failure, etc.

3. Air conditioner leakage: caused by blocked drain pipes, unbalanced installation, and rupture of condensate trays.

4. Air conditioner noise: caused by damage to fan blades, vibration of outdoor units, compressor failure, etc.

5. Peculiar smell of the air conditioner: caused by dirty filter, mold breeding inside the air conditioner, refrigerant leakage, etc.

6. Mismatch between indoor and outdoor units: Indoor and outdoor units are caused by inconsistent models, connection line failures, communication failures, etc.

7. Freezing of outdoor unit: caused by insufficient refrigerant, low outdoor temperature, poor air circulation, etc.

8. Remote control failure: the remote control battery is exhausted, the remote control is faulty, the receiver is faulty, etc.

9. Air conditioning circuit failure: caused by short circuit of circuit board, damage to components, loose terminals, etc.

10. Automatic power on/off of air conditioner: caused by thermostat failure, overheat protection, overload protection and other reasons.

The above is an overview of the common faults of air conditioners, and the specific faults need to be judged and repaired according to the actual situation. When encountering the above air conditioning failures, do not blindly disassemble the machine for self-repair, because most non-professionals do not have a special understanding of the air conditioning structure, and there are no professional maintenance tools, which may cause secondary damage to the air conditioner, therefore, it is recommended to contact professional maintenance personnel for inspection and maintenance.
