Galanz air conditioner shows what to do with F9

Galanz air conditioner F9 fault means that the outdoor temperature sensor is faulty, first see if the connection line of the sensor is broken, if not, use a multimeter to measure the resistance value, the resistance value is normal at about 5k, otherwise it should be replaced.

Galanz air conditioner F9 failure indicates that the outdoor temperature sensor is faulty.

Maintenance method: 1, see if the connection line of the sensor is broken, 2, use a multimeter to measure the resistance value, the resistance value is about 5k is normal.

Burn the thermostat of the internal unit with a fire and it will start. What's going on?

The air conditioner shows that F9 is faulty**: F9 refers to the protection of the PFC frequency board or the abnormal start of the outdoor fan. Scope of failure:

1.The frequency conversion module of the outdoor unit is short-circuited. 2.

The data of the outdoor unit is changed to the vertical finger frequency motherboard. 3.The temperature detection circuit of the outdoor unit is abnormal.

4.High voltage protection of the outdoor unit. 5.

The compressor is abnormal. Troubleshooting: first observe whether it can be started, check whether the power supply is good, whether the internal and external units are well ventilated, whether the pressure capacitance, whether the press is good or bad, whether the internal and external fans are rotating, whether the fan and fan capacitance are normal, and whether the AC contactor is working normally.

Summary. Hello, F9 refers to PFC frequency board protection or outdoor fan start abnormality.

Scope of failure: 1The frequency conversion module of the outdoor unit is short-circuited. 2.The data of the inverter motherboard of the outdoor unit is incorrect. 3.The temperature detection circuit of the outdoor unit is abnormal. 4.High voltage protection of the outdoor unit. 5.The compressor is abnormal.

Troubleshooting: 1. Observe whether it can be started, check whether the power supply, the ventilation of the internal and external units is good, the capacitance of the press, the quality of the press, whether the internal and external fans are turned, whether the capacitance of the fan and the fan is normal, whether the AC contactor works normally, whether the system is poor or fluorine is excessive. 2. Check the sensor again, the main control board, the fault will not exceed the scope of the machine, if you are not a professional, clean the filter screen, turn on the machine after 30 minutes of power failure, if it does not operate normally after 30 minutes, the outdoor unit will be faulty.

Galanz cabinet machine shows how to solve F9.

Hello, F9 refers to PFC frequency board protection or outdoor fan start abnormality. Scope of failure: 1

The frequency conversion module of the outdoor unit is short-circuited. 2.The data of the inverter motherboard of the outdoor unit is incorrect.

3.The temperature detection circuit of the outdoor unit is abnormal. 4.

High voltage protection of the outdoor unit. 5.The compressor is abnormal.

Troubleshooting: 1. Observe whether it can be started first, check whether the power supply is good, whether the ventilation of the internal and external units is good, whether the capacitance of the rotten voltage retarder, whether the press is good or bad, whether the internal and external fans turn or not, whether the capacitance of the fan and the fan is normal, whether the AC contactor works normally, whether the system is poor or fluorine is excessive. 2. Check the sensor again, the main control board, the fault will not exceed the scope of the machine, if it is not a professional, clean the filter screen, turn on the machine after 30 minutes of power failure, and if the stool does not operate normally after 30 minutes, the outdoor unit will be faulty.
