Guoxiang air conditioner shows faults 14 and 7

Fault phenomenon: 14 faults are displayed, and the air conditioner does not work and does not refrigerate.

Solution: 1. Once the indoor temperature E reaches the set temperature, the air conditioner will not run, and only the air conditioner temperature needs to be adjusted.

2. The contactor controlling the compressor and the cooling fan is damaged and needs to be repaired.

3. If the refrigerant is insufficient, add it.

4. The circuit board is damaged, there is no output signal, and it needs to be repaired.

5. Air conditioner overheating protection, stop using for one hour and then try at start.

6. The heat dissipation fan itself and related wiring faults need to be repaired.

When 7 is displayed, the sensor is changed.

Solution: Just replace the external sensor.

Common faults of Guoxiang air conditioner:

01 Refrigerant leakage internal fan Auxiliary heat can be operated, and other peripherals are turned off.

02 Compressor stall rotor closes the compressor The external fan and the inner machine can be operated.

03 Outdoor coil temperature sensor failure to shut down the compressor The outer fan and the inner fan can be operated.

04 Failure of the temperature sensor of the indoor coil"Fixed frequency machine: turn off the outer fan of the compressor, and the inner fan can operate; Inverter: Reduced frequency operation"。

05 The ambient temperature sensor of the indoor unit is faulty"The temperature sensor of the wire controller is invoked, and it is operating normally.

06The ambient temperature sensor of the outdoor unit is faulty"Fixed frequency machine: in heat2 4 specifications, skip the relevant conditions and continue to operate; Inverter: Reduced frequency operation"。

07 Exhaust or compressor top temperature sensor failure: shut down the compressor external fan.

08IPM module protection shuts down the compressor and the external fan continues to operate.

09. The overvoltage and undervoltage voltage of the outdoor unit will be restored after normal.

10. The compressor exhaust temperature is too high, and the compressor external fan is turned off.

11. The indoor unit corresponding to the abnormal communication between the indoor and outdoor units stops working.

12 retained, unused.

You can support the brand that we really master the core technology, Gree has always taken the route of environmental protection and energy saving, such as this Gree.

KFR-26GW (26561)FNAA-3 not only has an excellent thin design, the product is also very powerful, the energy efficiency ratio of the air conditioner can be up to the highest, only, the use of 2 generations of seamless evaporator, 21 dB ultra-quiet, 3-dimensional three-dimensional air supply, 7 levels of wind speed adjustable, intelligent energy saving and power saving. Can be considered.

Hello, the following is Guoxiang**Common Faults of Air Conditioners**Daquan: E0: Ambient temperature sensor failure.

E1: Indoor temperature sensor is faulty. e2：

The coil temperature sensor is faulty. E3: Exhaust gas temperature sensor is faulty.

E4: Faulty compressor high pressure sensor. e5：

Faulty compressor low pressure sensor. E6: Indoor and outdoor communication line failure.

E8: Compressor back-to-back mountain running overload protection. e9：

Compressor shutdown protection. f0: The indoor fan motor is faulty.

F1: Coil fan motor failure. f2：

The motor of the outdoor fan is faulty. F3: Indoor and outdoor communication line leakage fault.

F4: Compressor reversal protection. f5：

Anti-freezing protection of the outdoor unit. H1: Indoor temperature is too high protection.

H2: Indoor temperature too low protection. h3：

Coil temperature too high protection. H4: Coil temperature too low protection.

H5: Outdoor unit compressor overload protection. h6：

Low voltage protection of outdoor unit. H7: High voltage protection of outdoor unit.

p0: Drain pump failure. p1：

Indoor water pump malfunction. P2: Coil pump failure.

The above is the common fault of the air conditioner and its meaning. If you encounter other problems, you can consider contacting the technical support team of the aircon brand or seeking professional help.

Guoxiang air conditioner fault**Daquan Hello dear, 1 no power on D1-D4, D5, D6, D9 short circuit, IC6 short circuit, fuse open circuit 2 No wind motor does not rotate DC10 deterioration 3 No wind motor jitter, no + adjust R28 4 The compressor will stop working for a while, no compressor CT current CT1 open circuit Daqing Kuai EQ series 1 is not powered on (the power-on indicator light is not on) is not powered C1, C4, C19 deteriorate, T1, R4, R60 open circuit, VDZ2, D3, VD4, VD6, VD3, VD2, VD16, VD17, VC1 Short Circuit Spring Demolition Liquid Sensitive (1) When the Timer indicator is on, the RUN indicator flashes for 1 time for 8 seconds. Most of the causes of this failure occur in the abnormal thermistor of the heat exchanger of the indoor unit: please first check whether the thermistor is disconnected, measure and bury the jujube with the resistance file of the multimeter, 25 in normal times, and the measured resistance value is 5k (the thermistor is a resistance with a negative temperature coefficient, the resistance decreases with the increase of temperature, and the resistance value decreases with the temperature decreases).

If the resistance value is infinite, the thermistor should be replaced, and if the resistance value is normal, the printed circuit board should be replaced. (2) When the timer indicator is lit, the RUN indicator flashes 2 times for 8 seconds, the cause of this failure is caused by the disconnection of the suction thermistor of the indoor unit or poor contact. The inspection method is the same as (1).

Hello, glad to answer for you. <>

Guoxiang air conditioner failure**Daquan: First, if EE is displayed, it means that the communication between the indoor unit of the air conditioner and the wire controller is abnormal. Second, if e:

00 means that the temperature sensor of the environmental modification rubber environment of the line annihilation control is faulty. Third, the presence of e:01 indicates a leak in the refrigerant.

Fourth, if the air conditioner has e:03, it means that the temperature sensor of the outdoor coil is faulty. Guoxiang Air Conditioning is a large-scale high-tech air conditioning enterprise integrating product research and development, production, manufacturing and sales services.
