Why is the suction pressure low on my Haier CA0065EANR?
- S
  Stacy WalkerAug 20, 2025
  A low suction pressure in your Haier Chiller may stem from several causes. It could be due to insufficient refrigerant (adjust the charge of refrigerant), an 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 matters inside (clean up the incrustation scale), insufficient air capacity (check the fan), a short circuit in the air circuit (check the cause of short circuit and take troubleshooting), or incomplete defrosting (replace the poor 4-way valve or defrosting sensor).

How to fix high suction pressure in Haier CA0065EANR Chiller?
- P
  Paula AllenAug 22, 2025
  High suction pressure in your Haier Chiller can be caused by a few things: too high a charge of refrigerant (adjust the charge of refrigerant), high water inlet temperature at the water side (check the water temperature), or high ambient temperature of the air-side heat exchanger (check the ambient temperature).

What causes an over-current fault in a Haier Chiller compressor?
- J
  Jaclyn BarnettAug 26, 2025
  An over-current fault in your Haier Chiller's compressor could be due to high exhaust and suction pressures (refer to “High Exhaust Pressure” and “High Suction Pressure”), high or low voltage, single phase or phase imbalance (check the power supply), or a short circuit in the motor or terminal (check the terminal connections).

What causes too low exhaust pressure in Haier CA0065EANR?
- N
  Nicole GomezAug 28, 2025
  Too low exhaust pressure in your Haier Chiller can be attributed to a lack of refrigerant (adjust the charge of refrigerant), low suction pressure (refer to “Low Suction Pressure”), low ambient temperature of air-side heat exchanger (check the ambient temperature), or too low water temperature at the water side (check the water temperature).

What should I do if there is a fault in the flow switch of my Haier CA0065EANR Chiller?
- H
  Heather BrownAug 31, 2025
  A fault in the flow switch of your Haier Chiller may be due to several reasons: air found in the water system (discharge air via the exhaust valve), water-side heat exchanger scaling or foreign matters inside (clean up the incrustation scale), a poor switch (replace the target flow switch), unevenly distributed flow in water pipelines (adjust the flow in water pipelines via the shut-off valve), an out-of-service water pump (machine installation must be ganged), or insufficient types of water pumps (check it and try to fix it).

Why is my Haier CA0065EANR Chiller making abnormal noises?
- M
  Melissa HernandezSep 3, 2025
  Abnormal noise in your Haier Chiller could be caused by loose metal plate bolts (retighten bolts), liquid impact due to entry of liquid refrigerant into the compressor (adjust the charge of refrigerant or the poor throttling device), or a poor compressor (replace the compressor).

How do I troubleshoot a fault in communication of the wired controller in my Haier Chiller?
- P
  Patrick MejiaSep 5, 2025
  If you're experiencing a communication fault with the wired controller of your Haier Chiller, consider these potential causes: incorrect unit numbering (check the unit numbering, and correct it), incorrect connection of communication wires (check the order of connection of communication wires), a damaged PCB (replace the PCB), or a faulty wired controller (replace the wired controller).
S
Shawn BeckSep 8, 2025
What causes overtemperature of the exhaust temperature sensor in Haier Chiller?
- P
  Patricia Hart MDSep 8, 2025
  Overtemperature of the exhaust temperature sensor in your Haier Chiller may be caused by poor ventilation around the unit (clean up the obstacles around the unit, or add air ducts), too low ambient temperature (shut down), a dirty or clogged filter at the fluorine side (replace the filter), or incomplete frosting (for heating) or no frosting (change the frosting parameters).

What to do if there is an open circuit in the low-pressure sensor of my Haier Chiller?
- D
  Derrick ColeSep 12, 2025
  If there's an open circuit in the low-pressure sensor of your Haier Chiller, it's likely due to a damaged sensor (replace the sensor) or a poor connection of the sensor (reconnect the sensor).
M

What causes an open or short circuit in the temperature sensor of a Haier CA0065EANR Chiller?
- E
  Elaine RobinsonSep 13, 2025
  An open or short circuit in the temperature sensor of your Haier Chiller can result from a damaged sensor (replace the sensor) or a poor connection of the sensor (reconnect the sensor).
