What to do if Hitachi YUTAKI M RASM-5VNE Air Conditioner shows Failure of discharge gas pressure sensor?
If your Hitachi Air Conditioner displays a 'Failure of discharge gas pressure sensor', check the connectors for any looseness or breakage. The issue may be a loose, disconnected, broken, or short-circuited connector.
What to do if Hitachi 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 YUTAKI M RASM-5VNE 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 YUTAKI M RASM-5VNE 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.
What causes Abnormality of picking up circuit for protection (Outdoor unit) in Hitachi Air Conditioner?
If your Hitachi Air Conditioner displays 'Abnormality of picking up circuit for protection (Outdoor unit)', inspect indoor unit PCB and wiring. The cause can be a failure of indoor unit PCB, incorrect wiring, or connection to PCB in the indoor unit.
What to do if Hitachi YUTAKI M RASM-5VNE Air Conditioner shows Transmission error between Inverter PCB and Main PCB?
Inspect connection between Inverter PCB and Main PCB.
What does Decrease in discharge gas superheat mean for Hitachi YUTAKI M RASM-5VNE Air Conditioner?
If your Hitachi Air Conditioner displays 'Decrease in discharge gas superheat', check refrigerant charge and inspect related components. Possible causes are excessive refrigerant charge, failure of thermistor, incorrect wiring, incorrect piping connection, or expansion valve locking at opened position (disconnected connector).
How to solve RF Communication failure on Hitachi YUTAKI M RASM-5VNE?
If your Hitachi Air Conditioner shows 'RF Communication failure', check the RF communication setup. This issue occurs when there is no communication for 1 hour with one or two RF receivers which are bound to the RF-Bridge.
What causes Hitachi Air Conditioner hydraulic alarm pressure?
If your Hitachi Air Conditioner displays 'Hydraulic alarm pressure', check the system for any leaks or blockages affecting water pressure. This alarm indicates that water pressure is not detected in the hydraulic cycle.
How to fix Incorrect PCB Setting in Hitachi YUTAKI M RASM-5VNE Air Conditioner?
If your Hitachi Air Conditioner shows 'Incorrect PCB Setting', correct the DSW settings. This issue is caused by a wrong DSW setting in the case of Co041.
