I would like to ask why the internal fan of the Gree air conditioner does not work when heating, but

Gree air conditioner. The internal machine does not rotate during heating, but it can rotate during refrigeration, which is a problem with mode setting.

1. When the indoor unit of the air conditioner actually operates, the output point of the indoor unit is the same whether it is cooling or heating mode.

2. The air conditioner can be turned when it is refrigerated, which proves that the fan motor is okay and the motor is normal.

3. The air conditioner can be turned when it is refrigerated, which proves that the output circuit of the computer version is also normal.

According to the above analysis, it is only related to the setting mode.

Solution: 1. Turn on the air conditioner.

2. Adjust the mode of the remote control to the heating mode.

3. Adjust the wind speed again (adjust the wind speed to solve the problem).

4. Adjust the wind speed and hot air.

The internal unit does not rotate when the Gree air conditioner is heating, but it can rotate when cooling, which is a problem with the mode setting.

Whether it's hot or cold, what's inside is working.

1. Reason 1: The main control switch of the air conditioner is not in good contact, resulting in the air conditioner fan not being able to operate normally.

Maintenance method: Use a multimeter to test the resistance of the main control switch contact, if the resistance is too large or zero, then the main control switch should be repaired or replaced.

2. Reason 2: The pressure protection switch in the air conditioner is faulty.

Maintenance method: When the pressure protection switch of the air conditioner fails, we first need to measure whether the voltage on the pressure protection switch is normal, and whether its circuit is short-circuited, and then repair or replace the switch according to the measured results.

3. Reason 3: The motor coil of the air conditioning fan is damaged.

Maintenance method: Use a multimeter to measure whether the resistance of the fan coil is normal, if the coil of the air conditioning fan does have a problem, then you can ask a special maintenance master to repair and replace the coil when repairing.

4. Reason 4: Too much refrigerant in the air conditioner causes the protective shutdown of the air conditioner.

Maintenance method: the air conditioner also has an automatic protection function during operation, we don't think that the more refrigerant is added to the air conditioner, the better, too much air conditioning refrigerant will also cause the air conditioning fan not to rotate, at this time we need to take out the excess refrigerant from the air conditioner when repairing.

5. Reason 5: The fixing screw between the motor and the blade of the air conditioner fan is loose.

Maintenance method: If the air conditioner fan does not rotate due to loose screws, we only need to re-tighten the screws on the air conditioner fan.

6. Reason 6: Air conditioning fan capacitor short circuit or open circuit.

Maintenance method: If there is a short circuit or open circuit in the air conditioning fan, what we need to check is that there is a problem with the capacitor of the air conditioner, and then we need to replace the capacitor of the same specification.

If the Gree air conditioner turns on the refrigeration unit and the fan does not rotate, it should be that the fuse on the main board of the internal unit is burned.

Reasons and solutions for the fan not turning in the air conditioner.

1. Connect the power supply, turn the transfer switch to the windshield, and the fan will stop rotating. There are two reasons for this failure: one is that the fan does not move and there is no sound.

Second, the fan does not move, but it makes a "buzzing" sound. Before repairing, check whether the lead wire of the motor is falling off, and then check according to the following steps: if the motor does not move, it will not sound.

First of all, measure whether the four wires of the motor are broken or short-circuited, and then measure whether the sum of several resistances is equal to the rated resistance value, which is generally equal. If the motor is not faulty, the function transfer switch should be checked, the contacts should be turned on when the wind is strong, and the contacts should be turned on when the wind is weak. The fan does not rotate, but it makes a "buzzing" sound.

Observe whether the centrifugal fan is stuck, turn on the indoor unit, gently toggle the fan with your hand, the fan blades should have good inertia when running, if the fan is stuck, it should be adjusted first, and then check whether the capacitor C1 is damaged. When the function transfer switch is dialed to the "windshield" gear, although the fan rotates, it rotates slowly, and it cannot achieve the desired air conditioning effect, which may be that the fan is stuck, but it is not completely stuck, which needs to be adjusted.

When the ambient temperature is lower than the WDJ set temperature and the function transfer switch is turned to the "hot" mode, the air conditioner cannot heat up. There are also two reasons for such a failure: one is that the relay does not operate, and the other is that the relay does not operate, but there is no heating.

First, measure whether there is voltage at both ends of coil C, if there is no voltage, measure the two points of the function switch 1 and 2, the two ends of RU and the end and the hot end of WDJ are energized, under normal circumstances, their DC resistance is zero; If there is a voltage, measure whether the two points of the function switch 1 and 2, the two ends of the RU and the common and hot ends of the WDJ are unobstructed respectively. If the relay is in action and the air conditioner cannot heat, it is generally an electric heating wire with R2 open circuit, and it is not excluded that the relay contact is not in good contact. If the relay makes a screeching sound when it is operating, it is mostly due to a short circuit between the contacts of the relay during operation.

Most of the internal fans are controlled with thyristors. After turning on the power, use a tool to push the internal fan to observe whether the internal fan can start normally, if so. This indicates that there is a problem with the inner disk, and it can be speculated that the internal starting capacitor of the fan is damaged, if it is not started, it means that there may be a problem with the internal fan or the inner panel.

If it is confirmed that it is the inner board or the fan, the inner board can be removed and re-energized, and then the two feet opposite the thyristor drive can be shortened with the multimeter needle to observe whether the internal machine can rotate normally. If it works normally, it means that there is a problem with the inner disk, and if it does not rotate, it means that the inner motor is broken.

Questions. The power supply of the fan is not enough!

You can try the above methods to solve it, if it really doesn't work, it is recommended to go to the maintenance department for maintenance, you can refer to it, I hope it will help you.

The air conditioner turns on the refrigeration, the internal fan does not rotate, the internal fan does not rotate, and the words are the system in it, which may mean that it cannot be touched, and this should be the maintenance to take a look.

The reasons why the internal fan does not work when the Gree air conditioner is heating may be the following:

In the heating mode, the inner and lower fans do not need to work: in the heating mode, the internal fans do not need to work, because the heat needs to be absorbed from the outside to the indoor, and the internal temperature is high enough.

Internal fan failure: The internal fan is faulty, resulting in failure to work properly and needs to be repaired or replaced.

Control panel failure: The control panel of the air conditioner is faulty, resulting in the internal fan not working properly and needs to be repaired or replaced.

It should be noted that different models of Gree air conditioners may have different working principles and designs, so you need to refer to the instruction manual of the air conditioner or contact a cleaning professional for processing.

Dear, hello, here for you to query the information for the following reasons: the internal components of the outdoor unit are damaged maintenance method: the internal components of the air conditioner outside the unit are damaged will cause the air conditioner to not work normally, the air conditioning compressor is in the outside unit, if the starting capacitor in the air conditioning compressor is faulty, it will lead to the air conditioning outside the unit does not rotate, we need to check and repair the air conditioning compressor when repairing, if the compressor is seriously damaged, the compressor needs to be replaced, When the fan of the outdoor unit of the air conditioner is damaged and cannot be rotated, then the fan of the outdoor unit needs to be replaced in time.

Reason 2: Failure of the connection line of the air conditioner or the outside of the air conditioner maintenance method: the connection of the air conditioner or the outside unit of the circuit is short-circuited or broken, which will also lead to the air conditioner rushing to the outside unit does not turn, when encountering such a problem, we need to first check the line of the air conditioner, then we need to use the universal meter, in the check of which line has a problem, then you can repair it in time to ensure that the air conditioner can run normally.

Summary. 1.The bearing is jammed.

If you find that there is nothing wrong with the other parts of the air conditioner, then it should be that the bearing of the fan is stuck.

2.Air conditioner defrosting.

When the heating mode is turned on, there will be frost outside, and the air conditioning system will automatically enter the defrost mode. At this time, the external fan will stop running temporarily, but the compressor will continue to run and will automatically start heating when the defrosting is completed.

3.The set temperature is reached.

In automatic mode, when the room temperature reaches the set temperature, the fan stops running and the system is in standby mode.

4.The fan motor is damaged.

If the compressor is working properly and the fan is not turning, then it is possible that the fan motor is broken.

5.Start-up capacitor failure.

If the fan does not rotate, it may also be due to the faulty starting capacitor, check whether the starting capacitor is faulty.

The teacher recommends that you find a master to repair it.

Gree air conditioner can cool down, but there is no reason why the outside wind does not move when heating.

Please wait patiently for 5 minutes, we are sorting it out, and we will answer you immediately, and please do not end the consultation.

Dear, thank you for your patience 1The bearing is jammed. If you find that there is nothing wrong with the other parts of the air conditioner, then it should be that the bearing of the fan is stuck.

2.Air conditioner defrosting. When the heating mode is turned on, there will be frost outside, and the air conditioning system will automatically enter the defrost mode.

At this time, the fan will temporarily stop running, but the compressor will continue to run, and it will automatically start heating after the defrosting is completed. 3.The set temperature is reached.

In automatic mode, when the room temperature reaches the set temperature, the fan stops running and the system is in standby mode. 4.The fan motor is damaged.

If the compressor is working properly and the fan is not turning, then it is possible that the fan motor is broken. 5.Start-up capacitor failure.

If the fan does not rotate, it may also be due to the failure of the starting capacitor, check whether the starting capacitor is faulty. The teacher recommends that you find a master to repair it.

It can be moved when it is refrigerated.

The compressor is running.

Does it have anything to do with the motherboard?

Dear, this still has to be taken apart and looked at so that we can find the answer accurately, and this is also related.

It needs to be detected with equipment.

The bearings are good, I checked it, but there is no fan power supply.

Then check if the motherboard is a wiring problem.
