What s going on with the Gree air conditioner showing F6? How to solve it?

Check whether there is any contact between the connection line of the VTH PG motor and the feedback line. If the PG motor of the indoor unit is damaged, you need to replace the PG motor of the same model. If the starting capacitor of the indoor PG motor is damaged, the capacitor of the same capacity needs to be replaced.

Poor contact with circuits such as thyristors, optocouplers, or computer boards. If the chip is damaged, it needs to be replaced with a new motherboard of the same type. Because the indoor pipe temperature sensor is faulty, the first thing to check is whether the air conditioner can start normally and whether the air conditioner can work normally when the power supply is on.

Secondly, check whether the internal and external units are well ventilated. If the internal and external units are not well ventilated, it is likely to be due to machine failure. It is necessary to use professional equipment to check whether the compressor capacitance of the air conditioner is normal.

If there is a deviation, it is likely that the press is damaged. It is also possible that the AC contactor is not working properly. At this time, you need to contact professional after-sales personnel to replace the AC contactor and check whether the air conditioner has fluorine leakage.

If the fault is beyond the range of the machine, and you are not a professional, you need to turn off the power for 30 minutes before turning it on. If it still doesn't work properly, you need to ask a professional maintenance personnel to repair it.

F6 is refrigeration overload and frequency reduction, and the specific cause of the fault needs to be detected and dealt with by Gree service personnel. Please contact Gree National Customer Service**4008-365-315 for feedback on your needs and suggestions, or click here.

The air conditioner panel shows that F6 is the meaning of phase loss protection, the so-called phase loss is the normal three-phase power supply, one of the phases is broken, the original three-phase equipment will reduce the output power to make it unable to work normally or cause accidents. When the line power supply is out of phase, a negative sequence current component will be generated, and the three-phase current is unbalanced or too large, which will cause the motor to burn out. Therefore, in order to ensure the safe operation of the motor and avoid accidents, the general motor will be equipped with a phase loss protection device.

The air conditioner shows that F6 failure may be due to the following reasons: 1. Lack of phase. That is to say, one of the phases of the normal three-phase power supply is broken, and the original three-phase equipment reduces the output power to make it unable to work normally or cause an accident.

When the line power supply is out of phase, the negative sequence current component will be generated, and the three-phase current will be unbalanced or excessive, causing the motor to burn out quickly and the air conditioner will appear F6**.

Reasons why Gree air conditioner shows F6:

1. Observe whether there is contact between the PG motor connection line and the feedback line of the indoor unit.

2. If the PG motor of the indoor unit is damaged, the PG motor of the same model needs to be replaced.

3. The starting capacitor of the indoor PG motor is damaged, and the capacitor of the same capacity needs to be replaced.

4. The computer board controls the PG motor circuit failure or the computer board chip is damaged. When the PG motor circuit is repaired, it is mainly used to detect the poor contact between the thyristor and the optical combiner or other circuits or computers, and if the chip is damaged, it is necessary to replace the computer board of the same model with a new one.

The most likely cause of F6 failure in the air conditioner** is due to the following reasons:

1. The wiring of the outdoor sensor of the air conditioner falls off: when the air conditioner is installed, the wiring of the outdoor sensor is not firm, and after a period of use, the wiring part will easily fall off, resulting in the failure of the air conditioner to operate normally, and the fault of F6 will be displayed.

2. Operation overheating protection ruler: If Lingfeng does not clean the filter, condenser, and thermistor of the air conditioner for a long time, a large amount of dust will be generated, and these dirt that has not been cleaned for a long time will make the internal parts unable to dissipate heat normally, resulting in the phenomenon of overheating protection during operation.

Repair measures for the appearance of F6:

1. Check whether the wiring of each phase of the air conditioner power supply is normal.

Observe whether there is contact between the connection line of the PG motor of the indoor unit and the feedback line. (need to be plugged in again), the PG motor of the indoor unit is damaged. (Need to replace the same model of PG motor) indoor PG motor starting capacitor is damaged, (need to replace the capacitor of the same capacity), computer board control PG motor circuit failure or computer board chip damage.

When the PG motor circuit is repaired, it is mainly used to detect the poor contact between the thyristor and the optical combiner or other circuits or computers, and if the chip is damaged, it is necessary to replace the computer board of the same model with a new one.

F6 stands for fault content, outdoor coil, intermediate temperature sensor, fault or phase loss protection. The reason for the Gree air conditioner to appear F6 is the high-voltage failure of the air conditioner and the protection shutdown, the reason may be that the weather is too hot, the outdoor unit radiator is dirty and the heat cannot be dissipated, unplug the power supply and wait a few minutes to turn on the machine is because of this reason, the pressure returns to balance after the shutdown, and the machine cools down and the code trembling slag comes, so it can be started.

Gree air conditioner F6 fault solving skillsThe problem of the fan, if it can be refrigerated normally when it is just turned on, it means that the air conditioning compressor and the freon are basically normal, and the focus is on checking whether the speed of the fan is normal.

Observe whether there is contact between the PG motor connection line and the feedback line of the indoor unit, the PG motor of the indoor unit is damaged, the PG motor of the same model needs to be replaced, the starting capacitor of the indoor PG motor is damaged, the capacitor of the same capacity needs to be replaced, the computer board controls the PG motor circuit is silently faulty or the computer board chip is damaged.

F6 error** usually indicates a communication failure of the air conditioner's indoor and outdoor units. This can be caused by poor cable connection, missing cables, damaged cables, too far distance between indoor and outdoor units, or other communication issues. The construction bureau agreed to check whether the cable connection is firm, and Bu Xun asked to check whether the cable was damaged, and ensure that the distance between the indoor and outdoor units did not exceed the specified distance.

The air conditioner reports F6 fault**, which means that the outdoor unit of the air conditioner is faulty, which means that the outdoor pipe temperature sensor bridge is faulty.

Possible reasons are:

The sensor pins are loose or have poor contact, and the pins need to be reinserted or the contact corrected.

The sensor is damaged and needs to be replaced.

The circuit board is damaged, there is no output signal, and the circuit board needs to be replaced.

If your air conditioner is experiencing F6 failure**, it is recommended that you contact a professional for inspection and repair.
