Daikin is a collection of air conditioners.Refrigerant.Compressor development.Production.Sales.Service as a professional multinational enterprise.From home.Office buildings.Shops and other everyday spaces, to domed stadiums.Large facilities such as airports and special environments such as hospitals.Here's a look at Daikin air conditioners.

Daikin Air Conditioner Repair

The following code applies to FTY223C, FTY353C, FTY453C, FTY603C and other models, the machine to achieve automatic diagnosis of the fault function is: when press the air conditioner to select the mode of operation, then press the time key for more than 3 seconds, the air conditioner automatically enter the fault diagnosis test state, and then press the abnormal signal detection key, if there is a fault, the fault code will appear on thetemperature display of the LCD board
A6 Fan system fault, fan motor is faulty
C4 outdoor tube temperature thermistor is faulty
C9 faulty outdoor breeze thermistor
U4 indoor unit and outdoor control line contact is bad or connected wrong
U5 Poor contact between indoor unit and remote control
E5 Overload can overload the compressor
E3 high pressure is too high to make the pressure relay open to protect
H3 High pressure controller itself is faulty
H9 Outdoor temperature sensor itself is faulty
J6 Faulty thermostat sensor in heat exchanger
P3 Faulty thermostat in the electrical box

How about Daikin air conditioner

Case: Daikin KFR-120LWD type air conditioner, no response when the power is turned on
Fault phenomenon: After the power is turned on, the machine does not start, the power indicator does not light up, and the machine does not respond.
Failure analysis: the machine does not respond, the power indicator does not light, this failure is mostly due to abnormalities in the power supply circuit, should start here to detect.
Troubleshooting
1. determine the approximate location of the fault
(1) visual inspection, found that the circuit board voltage sensitive resistor and fuse has been damaged due to overvoltage.
(2) check the power supply voltage, using a multimeter to measure the single-phase 220V. three-phase 380V voltage is basically normal.
(3) the damaged varistor and fuse for new parts after the power supply test, found that the fan motor of the indoor unit basically does not rotate, while in the rotation of the moment appeared la.La. la sound.
(4) Then check the single-phase voltage, it was found that the voltage oscillates constantly between 220V and 100V.It is inferred that the fault may be in the user's power supply, and it is likely that the fault is caused by the disconnection of one phase of the power supply.
(5) The user is using a three-phase power supply, and further inspection of the user's switchboard results in a disconnection of its zero line.
2. Troubleshooting
After reconnecting the zero line, turn on the power and try the machine, the air conditioner starts to run normally, the fault is eliminated.
Tip: Some faults of the air conditioner are caused by poor power lines at the user.Inspection should take note of this point, such as checking the air conditioner itself is not found to be faulty, it should be considered whether the user power supply line failure.
