What to do if Hitachi YUTAKI M RASM-6NE Air Conditioner shows abnormal transmission between outdoor and indoor units?
If your Hitachi Air Conditioner shows 'Abnormal transmission between outdoor and indoor units', check the wiring, terminals, and PCB for faults. This issue can be caused by incorrect wiring, loose terminals, PCB failure, a tripped fuse, or the power supply being OFF.
Why does my Hitachi Air Conditioner activate safety device from excessively high discharge pressure?
If your Hitachi Air Conditioner activates the safety device due to excessively high discharge pressure, inspect the heat exchanger and refrigerant conditions. This activation can be caused by overload (obstruction of HEX, short circuit), a mixture of inert gas, or excessive refrigerant.
What causes Hitachi Air Conditioner to activate safety device from excessively low suction pressure?
If your Hitachi Air Conditioner activates the safety device from excessively low suction pressure, inspect refrigerant levels and piping for blockages. This issue is often due to a shortage or leakage of refrigerant, piping clogging, a closed expansion valve, or a locked fan motor.
How to troubleshoot Hitachi YUTAKI M RASM-6NE Air Conditioner hydraulic alarm flow and water pump malfunction?
If your Hitachi Air Conditioner displays a hydraulic alarm related to flow and water pump malfunction, check the water pump for proper operation and repair or replace it if defective. This alarm indicates that water flow is not detected in the hydraulic cycle or the pump is defective.
What to do if Hitachi Air Conditioner shows Thermostat Heater Alarm?
If your Hitachi Air Conditioner is showing a high temperature in the electric heater, check the electric heater for proper operation.
How to fix Hitachi YUTAKI M RASM-6NE Air Conditioner activation of overcurrent protection?
If your Hitachi Air Conditioner activates overcurrent protection, inspect the inverter PCB and compressor operation. This can be caused by overload, overcurrent, failure of the Inverter PCB, a clogged heat exchanger, a locked compressor, or EVI/EVO failure.
How do I fix a 'Unit Capacity setting Error' on my Hitachi Air Conditioner?
