To Next PageTo Next PageWhy is my Haier CA0035EANE making abnormal noise?
If your Haier Air Conditioner is making an abnormal noise, it could be due to loose metal plate bolts. Try retightening them. Alternatively, the noise might be caused by liquid refrigerant entering the compressor. In this case, adjust the charge of refrigerant or the throttling device.
Why is the suction pressure low in my Haier CA0035EANE Air Conditioner?
If your Haier Air Conditioner has low suction pressure, it could be due to several reasons. You might have insufficient refrigerant, in which case you should adjust the refrigerant charge. Another cause could be an undesirable low-pressure switch, which would need to be replaced. Insufficient water flow or low water inlet temperature at the water side could also cause this, requiring you to check the water flow and temperature, respectively. A scaled or obstructed water-side heat exchanger, insufficient air capacity (check the fan), a short circuit in the air circuit (find the cause and troubleshoot), or incomplete defrosting (replace the 4-way valve or defrosting sensor) are other potential causes.
How to fix fault in communication of wired controller in Haier Air Conditioner?
If there's a fault in the communication of the wired controller for your Haier Air Conditioner, the unit numbering might be incorrect; check and correct it. Also, the connection of communication wires could be incorrect; check their order. A damaged PCB could also be the problem, requiring replacement. Finally, the wired controller itself might be faulty and need replacement.
What causes too low exhaust pressure in Haier CA0035EANE?
If the exhaust pressure of your Haier Air Conditioner is too low, it could be due to a lack of refrigerant, so adjust the charge. It might also be caused by low suction pressure. Low ambient temperature of the air-side heat exchanger or too low water temperature at the water side could also be the cause; check the ambient and water temperatures respectively.
What causes high suction pressure in Haier CA0035EANE?
High suction pressure in your Haier Air Conditioner can be caused by a few things. You might have too high a charge of refrigerant; in that case, adjust the charge. Another possibility is a high water inlet temperature at the water side; check the water temperature. It could also be due to a high ambient temperature of the air-side heat exchanger; check the ambient temperature.
What to do if there is a fault in flow switch of Haier CA0035EANE Air Conditioner?
If there is a fault in the flow switch of your Haier Air Conditioner, there might be air in the water system, which can be resolved by discharging air via the exhaust valve. Alternatively, the water-side heat exchanger might have scaling or foreign matter inside, requiring you to clean the incrustation scale. The switch itself could be poor and need replacement. Unevenly distributed flow in water pipelines can also cause this issue; adjust the flow via the shut-off valve. An out-of-service water pump might be the cause, requiring machine installation. Insufficient types of water pumps could be the reason, so check and try to fix it.
What causes overtemperature of exhaust temperature sensor in Haier CA0035EANE?
If the exhaust temperature sensor of your Haier Air Conditioner is over temperature, it could be due to poor ventilation around the unit. Try cleaning up any obstacles or adding air ducts. It could also be caused by too low an ambient temperature, in which case you should shut down the unit. A dirty or clogged filter at the fluorine side could also be the cause, so replace the filter. Finally, incomplete or no frosting (for heating) could be the issue; change the frosting parameters.
What to do if Haier CA0035EANE has open or short circuit of temperature sensor?
If your Haier Air Conditioner's temperature sensor has an open or short circuit, it could be due to a damaged sensor, in which case you should replace it. Alternatively, it could be due to a poor connection of the sensor; try reconnecting it.
What causes open circuit in low-pressure sensor of Haier Air Conditioner?
If there is an open circuit in the low-pressure sensor of your Haier Air Conditioner, it might be because the sensor is damaged, and you'll need to replace it. It could also be due to a poor connection of the sensor; try reconnecting it.
