Hourly repair call
Full health type hang-up display content fault type
After the fault is turned on, the indoor temperature is very cold and the machine still does not stop
br/> It may be that the temperature control fails and the treatment method needs to be changed.
Whether the user turns the temperature control switch to the lowest point on the far right.
The air volume at the faulty air outlet is very small and the temperature cannot be lowered
The filter may be blocked by dust.
The fan rotates slowly, replace or replace the capacitor.
The fan blade fixing screw is loose.
Fault: Some capillary tubes are too soft, causing noise due to vibration during operation
The capillary tube hits the axial flow fan blade. Carefully check whether there is any jamming or deflection. If it is intact, readjust and tie it up
Fault Loud noise and vibration
Improper installation, the fixing screw feet of the mounting bracket are not properly padded or not tightened.
Due to the deflection of the long-distance transmission mounting bolt feet, the compressor is uneven and squeezed, causing vibration and noise.
The axial flow fan blades touch the guide ring.
The capillary collides with the fan blades.
If the pipeline collides or vibrates with the shell, the bandaging needs to be readjusted.
No water flows out of the faulty water heater
The voltage is too low and the water heater keeps turning on and off. If it is turned on for a short time and stopped for a long time, the condensed water in the chassis will be blown by the axial flow blades
evaporates on the condenser.
The room is closed for a long time when the machine is turned on, causing indoor dryness, or the weather itself is dry.
Cannot operate after the fault is powered on
The contacts of the main command switch selector switch are damaged and loose.
The wiring is wrong and the wire plug is detached.
The temperature control is out of order. It is a quality problem. Replace the temperature control.
Faulty water heater leaking electricity
The user socket is not grounded, which is an induced voltage.
The live and neutral wires are mixed.
The control board is damp, and the resistance of the insulated gauging meter to the ground is less than.
The temperature control panel of the window machine is squeezed, and the protective cover is aging and deteriorating, causing leakage.
Check whether the compressor is leaking electricity.
The live wire skin is cracked or peeled off, causing leakage.
The lights on the light panel of the fault window machine do not light up or the lights light up at the same time
The fuse is blown.
The resistor and light-emitting diode are burned out
Haier cabinet fault analysis complete list
After the fault is powered on, there is no response, the light does not flash and the buzzer does not sound.
Check the indoor unit wiring board to see if there is working voltage between the positions.
Check whether the fuse is blown.
Check whether the transformer has normal output of yellow group and white group.
Check whether there is a + output. If it is too low, check whether there is leakage.
The faulty start-up operation indicator light flashes, the machine is stopped, and the display is displayed.
Displayed immediately upon booting up.
Check whether the bits in the six-core wire are connected. If there is no connection, it is an outdoor fault. You should check whether the connection of the six-core wire is reliable and whether the high-voltage protector, overcurrent protector and overheating protector are connected.
For example, bit path, it is a fault in the indoor control part.
Displayed after running for a while.
Check the running current. If the current reaches the protection level, the overcurrent protector is working.
Check the high voltage of the system. If the protection is activated when it reaches the above level, it is a pressure protection function
Specific inspection
Whether the power supply is normal, whether there is a phase loss in the live wire and the neutral wire, whether there is mixed current protection.
Is the outdoor condenser clean?
Check whether the outdoor fan is running normally and whether the fan blades are broken.
Whether the pipeline is blocked or whether there is too much fluorine.
Whether the valve is fully open.
Whether the installation location is appropriate.
After the fault is turned on, the room temperature shows zero degrees and the cooling operation cannot be performed.
Check whether the indoor temperature sensing head is broken.
Is the temperature sensing plug plugged in properly?
Check whether the resistance between the pin ends of the temperature sensing plug of the display panel is lower than this value, then the display panel is leaking electricity, just remove it

The fault is displayed after powering on or after working for a period of time.
The reason is that the evaporator is frosted and incorrectly protected.
Check whether the indoor pipe temperature head is broken.
Is the indoor temperature sensing plug plugged in properly?
Check the temperature sensing plug of the display board to see if the resistance between the pins is lower than this value. If it is lower than this value, it means there is leakage from the display board. Just remove it.

When the machine fails to start, the indoor temperature is displayed and the refrigeration unit does not stop.
Cause The indoor temperature sensor head is short-circuited.
Check
whether there is water accumulation in the temperature sensing plug, causing a water short circuit.
Is the resistance of the indoor temperature sensor head normal?
When the fault starts, the indoor and outdoor fans run, the temperature is normal, and the compressor does not start.
Check
whether the six-core wire has normal working voltage.
Whether the AC contactor is burned out.
Are the compressor capacitor and compressor normal?
If the voltage is normal when the power is turned off, but drops to less than 100 volts after the power is turned off, then the neutral line and the three live wires of the power supply are not
from the same transformer.
