Oaks inverter air conditioner shows what F8 means

If the following can't solve your problem, you can directly find after-sales!

Faulty air conditioner? I'll tell you how to solve these failures, which should save you a lot of detours.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The press does not start, there is no problem with the temperature setting, but there is no response when the power is on? If the press does not turn the fan, you must look at the capacitor first.

The capacitor bulge needs to be replaced, and the capacitor is checked for power supply.

If there is a power supply, the overload protection of the press checker is the key.

If there is no power supply in the house, first check the connecting wires.

Secondly, it is best to look at the temperature control and replace the temperature control.

The relay is a key point, and the front drive should be judged.

If all of the above are normal, the following things will be easy to do.

Motherboard repair or replacement is subject to the user's decision.

The air conditioner is not refrigerated well or not refrigerated].

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

- Finally, I wish the work to go well, fix the air conditioner as soon as possible, live happily ——— attentively, please give an answer if you think it is good, give a good review, and wish you a better life———

Under-voltage protection, unplug it and take a look.

F9 is a general fault of the air conditioner**, on behalf of PCF protection, the general cause of the fault is loose pins, poor contact or disconnection, abnormal internal control circuit board, external control circuit board failure, main control circuit board failure.

If there is a problem with the air conditioner, it will appear**. It may be that the outdoor tube temperature sensor is faulty. Observe whether it can be started and check the power supply. Then look at whether the ventilation of the internal and external fans is good, whether the internal and external fans rotate, whether the capacitance of the fans and fans is normal, and the AC contactor.

Whether it is working properly and whether the system is poor or fluorine is excessive. If there is a problem with the air conditioner, you can take a look at the instruction manual first.

Maintenance during the start-up of the air conditioner:

After the air conditioner is turned on, the maintenance times during the air conditioner start-up process are determined by many factors such as environmental conditions, climatic conditions, number of hours of start-up, surrounding dust, air cleanliness, and whether the room is clean. The environmental conditions are not good, the weather is hot, the air conditioner is outdated, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner start-up process increases, usually once every month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, the air conditioner is turned on reasonably, and the electric fan.

Alternate use, the maintenance interval can be appropriately extended, from the air conditioner to the air conditioner shutdown maintenance 1-2 times. Maintenance should be careful and careful, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and refrigeration effect, and achieve energy saving, freshness and comfort.

The above content refers to Encyclopedia - Air Conditioning.

The main chip crashes due to reasons such as the external controller radiator touching the air guide ring of the panel (which can be restored by isolation), and the broken skin and leakage of the sensor wire.

The sensor is open or short-circuited, check the sensor resistance, generally more than 5k, if there is no resistance, the sensor is broken.

Summary. The Oaks air conditioner shows F8 indicating that the indoor coil temperature sensor is faulty, and the possible cause is that the sensor lead plug is loose. It is recommended to open the panel of the indoor unit, open the cover of the black electrical box, and replug the connector of the lead.

Because different air conditioner models, the meaning of the fault ** will be different, so it is recommended that the user consult the instruction manual to understand the specific fault content.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

Oaks air conditioner display F8 indicates that the indoor coil Bu Wangmin temperature sensor is faulty, and the possible reason is that the sensor lead plug is loose. It is recommended to open the panel of the indoor unit, open the cover of the black electrical box, and reconnect the plug of the lead wire to the lease. Because different air conditioner models, the meaning of the phenotype of the fault ** will be different, so it is recommended that the user consult the instruction manual to understand the specific fault content.

Mine is a 51 cabinet machine with two horses.

You can try to open the panel of the indoor unit, open the lid of the black electrical box, and replug the plug of the lead.

I measured it, and the two sensors were and kiloohms.

After replugging and unplugging, the power-on fault persists.

Try plugging the lead wire back in.

Still restarting.

Let's see if it's okay.

Plugging and unplugging back and forth several times, the fault is still the same, measuring the bus voltage of the external machine digging and taking the bus 305, and the two Guan Qingsan delay temperature sensors are and thousands of ohms, I don't know if this Qianyu Leou is normal? This sensor is at the bottom, and the top is thousands of ohms.

Why don't you speak? I'm at a loss now, this air conditioner Zhao Song exploded the filter wave capacitor half a year ago, and leaked a lot of electrolyte to the mold Zheng block board, and the branch answered a simple plug I don't know if there is any impact on this?

Yes, residual electrolyte can corrode the motherboard.

If you say that, it's probably a problem with the motherboard.

The ambient temperature of the two sensors is the same, I just don't know if the upper and lower tube temperature sensors of the external unit are not the same resistance!

The resistance is the same.

Summary. The Oaks air conditioner displays F8 fault, which means that the temperature sensor of the outdoor unit is faulty.

There are three reasons for the failure of Oaks air conditioner F8:

1. The sensor pins are loose or in poor contact.

2. The sensor is damaged and the resistance value is wrong.

3. The control circuit board is faulty, and the control signal cannot be received and sent.

Oaks air conditioner shows what fault the F8 is.

Oaks air conditioner display F8 fault means that the outdoor unit temperature sensor failure The reasons for the F8 failure of Oaks air conditioner are as follows: 1. The sensor pin is loose or has poor contact. 2. The sensor is damaged and the resistance value is wrong.

3. The control circuit board is faulty, and it is impossible to receive and send Zheng Shigao back to send out the control signal and shout the alarm.

Use or do not replace the driver board.

It has nothing to do with the drive.

The sensor is broken.

It would be nice to change the sensor.

It's good to change it. It is recommended that you ask the master to come and change it.

It's not very easy to change.

Okay thank you. No, you don't.

Can you give me a thumbs up?

The condenser of the external unit is dirty, high pressure protection!

Oaks air conditioner display failure**F1 generally has the following reasons, including module failure, high-voltage switch failure, automatic recovery or indoor unit thermistor disconnection and damage. Here's how to solve the problem:

1. If it is a module or high-voltage switch failure, it is recommended to contact professional after-sales or professional maintenance personnel to solve it.

2. If the thermistor of the outdoor unit is broken or damaged, you only need to buy a temperature sensor and reinstall it.

There may also be thermal protection, such as the fan not moving.
