The Daikin air conditioner is turned on for ten minutes to show what is wrong with the F3

Analysis of the causes of F3 failures of Haier inverter air conditioners:

1.If the communication fails, check whether the black cable with the outdoor unit is loose. If not, look for after-sales maintenance.

2.If F3 is displayed, it is the motor stalled or the motor does not rotate fault.

It means that the air conditioner is too dirty. Turn off the main power, open the lower cover, and pull out the filter screen for cleaning; Clean the electrostatic precipitator with a brush.

The solution to the failure of Haier inverter air conditioner**F3:

1.If there is still a problem with the connection as shown in the diagram, please pay attention to observe whether the wire on the terminal block is connected incorrectly.

2.Power on: Unplug the power for a few seconds and then call it back, turn it on and try it.

3.If the signal line of the internal and external unit is broken or leakage, replace the indoor and outdoor connection signal wires and try the machine again.

4.If the circuit board is broken, replace the circuit board of the indoor unit.

The motor is overheating. Since its establishment in 1924, Daikin Group has grown and developed into a multinational enterprise active in various fields such as air conditioning, refrigeration, fluorine chemistry, electronics, hydraulic machinery, etc., especially in air conditioning and refrigeration, with as many as 5,000 kinds of products, and is the world's multinational enterprise integrating R&D, production and sales of air conditioners, refrigerants and compressors.

Especially in the field of air conditioning and refrigeration, there are as many as 5,000 kinds of products, and the market share in Japan has always been the first, and it is the only multinational enterprise in the world that integrates R&D, production and sales of air conditioners, refrigerants and compressors. Today, Daikin has more than 200 production sites and sales offices around the world, employing more than 41,000 people, and is moving forward with unprecedented globalization.

The birth of Daikin ushered in a new era of multi-unit air conditioning systems for buildings. [VRV] is an abbreviation for Variable Refrigerant Volume, ie"Variable refrigerant flow"The system realizes refrigeration or heating through the direct evaporation or condensation of the refrigerant, which effectively reduces the power required for the mobile heat of the circulating water pump and fan necessary for the traditional air conditioner, and realizes the partition independent control of the system, which has won wide recognition after being listed in 1982, and the market response is extremely enthusiastic.

Daikin Air Conditioner F3 Failure The temperature sensor of the outlet pipe of the Daikin indoor unit is faulty, and the system pressure is abnormal or the sensor is open. You can also use the power off restart trick to try before the real fault repair, it is possible to restart it, don't laugh, this trick can reduce the repair order by 30%, and it saves a lot of costs for out-of-warranty users.

Fault**: f3

Hello, Daikin Air Conditioning.

The occurrence of f3 is indicatedRefrigeration overload protection, i.e. the internal evaporator.

Freeze. Possible causes of the air conditioner showing F3 failure** are:

The air conditioner inside the machine is too dirty。Solution: Disconnect the power supply, open the lid of the inner unit, and take out the filter screen to clean; Clean the electrostatic precipitator with a brush.

The internal machine filter and evaporator are dirty and blockedSolution: You need to find a professional maintenance personnel to clean and maintain the air conditioner.

Air conditioning refrigerantMissing or leaking。Solution: You need to find a professional maintenance personnel to check the amount of refrigeration, if there is no refrigerant, add refrigerant.

If the refrigeration duct is clogged, clean the duct.

There is a problem with the connection line between the internal and external units。Solution: You need to find a professional maintenance personnel to check whether the connection cable is normal.

The air conditioner circuit board is brokenSolution: You need to find a professional repair personnel to check whether the circuit board is damaged, if you need to replace the new and old circuit motherboard.

The above is the meaning of the air conditioner display f3 fault**, its common causes and solutions, I hope mine can help you, thank you

Air conditioner failure** indicates:

F1-Indoor Unit Ring Temperature Sensing Bag Failure;

F2-Indoor unit tube temperature sensing bag failure;

F3-Outdoor unit ring temperature sensor package failure;

F4-Outdoor unit tube temperature sensor package failure;

F5-Outdoor press exhaust temperature sensor bag failure.

Acceleration in place is different, so it doesn't make much sense to detect both at idle and in place7

The battery is out of power and can't catch fire:

Cause of failure: Although many vehicles use maintenance-free batteries, it is often difficult to find out if there is a problem with the battery. When the battery voltage is insufficient during driving, the engine will not start.

There are usually two situations when the battery is out of power, the battery life is generally 2 to 3 years, and when the battery life expires, it will suddenly run out of power when it is stopped; There is also the fact that we listen to the radio for a long time, forget to turn off the headlights, and the alarm of the immobilizer for a long time, etc., which causes the battery to be out of power.

Solution: 1. Pulled and started by other vehicles.

2. Borrow the power supply of other vehicles to start.

3. Use downhill to start.

Low oil alarm light on:

Cause of failure: the red light of the oil pot is on, if it is not a sensor failure, it is generally the lack of engine oil, and continuing to drive in the absence of oil is likely to cause the piston to break the cylinder block, and the car will suddenly shut down, which is not only very dangerous, but also the next maintenance cost is also very high.

Parking inspection ant Jingxin check:

1. Some cars burn engine oil, and car owners should be very experienced and can add matching engine oil by themselves. In the open suburbs there is no other vehicle to help, and have to drive forward, and there is no oil nearby, you can temporarily go to some stalls to buy soybean stuffy wheel oil or peanut oil temporarily, and you should change the oil immediately after driving to the repair shop, otherwise it will leave a lot of charcoal. This is a last resort.

If you have other vehicles, you can borrow oil from them.

2. If you accidentally bump into the fuel tank and cause oil leakage, and there is no maintenance location nearby, we can chew the gum and paste it on the oil leakage part of the fuel tank, because after the chewing gum dries, it can tightly block the dripping oil part, which plays a good role in emergency relief.

3. If the oil circuit is damaged due to impact, don't add engine oil and ask for road assistance.

Brake light alarm on:

Cause of failure: If we encounter the brake warning light on during the long distance, it means that the brake fluid level is not enough, and the brake system may be leaking.

Special reminder: at this time do not continue to drive, must be added in time to buy brake oil, if due to environmental factors can not buy brake fluid, you can buy a high number of liquor temporarily replaced, will not affect the effect of brakes, but can not brake frequently, should be immediately driven to the repair shop after the emergency maintenance.

Before traveling, it is necessary to check whether the braking system is normal, including: the degree of wear and tear of the brake pads, and also pay attention to whether the booster oil is sufficient. Special attention should be paid to the sub-cylinder dust jacket of the braking system, because if this part breaks into the dust, it will cause the piston to fail, which will lead to the increase of the braking distance when braking; If water enters this part, brake failure will occur due to water mixed with the brake fluid.

Therefore, whether the dust jacket enters water or dust, it must be comprehensively inspected and repaired to prevent the brake from failing for long-distance driving.

I hope the subject and netizens are grateful.
