If the Haier Chiller's compressor has an over-current fault, it could be due to high exhaust and suction pressures (refer to "High Exhaust Pressure” and "High Suction Pressure”), high or low voltage, single-phase operation, or phase imbalance (check the power supply). It could also be caused by a short circuit in the motor or terminal (check the terminal connections).
What causes low suction pressure in my Haier Air Conditioner?
Low suction pressure in your Haier Air Conditioner may occur due to: * Insufficient refrigerant: Adjust the charge of refrigerant. * Undesirable low-pressure switch: Replace the low-pressure switch. * Insufficient water flow: Check the water flow. * Low water inlet temperature at the water side: Check the water temperature. * Water-side heat exchanger scaling or foreign matter inside: Clean up the incrustation scale. * Insufficient air capacity: Check the fan. * Short circuit in the air circuit: Check the cause of the short circuit and troubleshoot. * Incomplete defrosting: Replace the poor 4-way valve or defrosting sensor.
How to fix abnormal noise in Haier Air Conditioner?
Abnormal noise in your Haier Air Conditioner can be caused by: * Loose metal plate bolts: Retighten the bolts. * Liquid impact due to entry of liquid refrigerant into the compressor: Adjust the charge of refrigerant or the poor throttling device. * Poor compressor: Replace the compressor.
What to do if the exhaust pressure is too low on my Haier Air Conditioner?
Too low exhaust pressure in your Haier Air Conditioner can be caused by: * Lack of refrigerant: Adjust the charge of refrigerant. * Low suction pressure: Refer to “Low Suction Pressure”. * Low ambient temperature of the air-side heat exchanger: Check the ambient temperature. * Too low water temperature at the water side: Check the water temperature.
What causes an over-current fault in the compressor of a Haier Air Conditioner?
An over-current fault in the compressor of your Haier Air Conditioner may be due to: * High exhaust pressure and high suction pressure: Refer to “High Exhaust Pressure” and “High Suction Pressure”. * High or low voltage, single phase or phase imbalance: Check the power supply. * Short circuit in motor or terminal: Check the terminal connections.
What causes too high exhaust pressure in a Haier Air Conditioner?
Too high exhaust pressure in your Haier Air Conditioner may be due to several reasons: * Air or non-condensable gas in the system: Discharge and empty the non-condensable gas if necessary. * High suction pressure: Refer to “High Suction Pressure”. * Undesirable high-pressure switch: Replace the high-pressure switch. * Dirty or clogged condenser fin: Clean the air-side heat exchanger. * Insufficient air capacity or faulty condenser fan: Check the fan. * High refrigerant charge: Adjust the refrigerant charge. * High ambient temperature: Inspect the ambient temperature. * Insufficient water flow: Check the water flow. * Water-side heat exchanger scaling or foreign matter inside: Clean up the incrustation scale. * High outlet temperature of the water-side heat exchanger: C...
What causes an open circuit in the low-pressure sensor of a Haier CA0035EAND?
If the low-pressure sensor in the Haier Chiller has an open circuit, it could be due to a damaged sensor (replace the sensor) or a poor connection of the sensor (reconnect the sensor).
What causes an open or short circuit of the temperature sensor in Haier CA0035EAND Chiller?
If the temperature sensor in your Haier Chiller has an open or short circuit, it is likely due to a damaged sensor (replace it) or a poor connection of the sensor (reconnect it).
Why is the Haier CA0035EAND Chiller exhaust temperature sensor showing overtemperature?
If the Haier Chiller's exhaust temperature sensor shows overtemperature, it might be caused by poor ventilation around the unit (clean obstacles or add air ducts), too low ambient temperature (shut down the unit), a dirty or clogged filter on the fluorine side (replace the filter), or incomplete frosting (for heating) or no frosting (change the frosting parameters).
What to do if my Haier CA0035EAND has low suction pressure?
If your Haier Chiller has low suction pressure, it could be due to insufficient refrigerant (adjust the charge), a faulty low-pressure switch (replace it), insufficient water flow (check the water flow), low water inlet temperature at the water side (check the water temperature), scaling or foreign matter inside the water-side heat exchanger (clean up the incrustation scale), insufficient air capacity (check the fan), a short circuit in the air circuit (check the cause and troubleshoot), or incomplete defrosting (replace the poor 4-way valve or defrosting sensor).
