What causes indoor gas pipe temperature thermistor abnormality (THM G) in my Hitachi YUTAKI S80?
An indoor gas pipe temperature thermistor abnormality in your Hitachi Air Conditioner can be caused by a loose, disconnected, broken or short-circuited connector.
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.
How to fix Incorrect PCB Setting in Hitachi 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.
What causes unit capacity setting error in my Hitachi YUTAKI S80?
Unit capacity setting error in your Hitachi Air Conditioner is caused if there is no concordance between indoor outdoor unit capacity.
What causes compressor-top temperature thermistor abnormality in my Hitachi YUTAKI S80?
A compressor-top temperature thermistor abnormality in your Hitachi Air Conditioner can be caused by a loose, disconnected, broken or short-circuited connector.
What to do if Hitachi YUTAKI S80 shows Transistor module protection activation?
Inspect the transistor module conditions.
What causes suction pressure decrease prevention to activate in my Hitachi YUTAKI S80 Air Conditioner?
Activation of suction pressure decrease prevention in your Hitachi Air Conditioner can be caused by a shortage or leakage of refrigerant, piping clogging, a close-locked expansion valve, or a locked fan motor.
What causes RF communication failure in my Hitachi YUTAKI S80?
RF communication failure in your Hitachi Air Conditioner happens when there is no communication for 1 hour with one or two RF receivers which are bound to the RF-Bridge.
What causes outdoor protection detection circuit abnormality in my Hitachi YUTAKI S80?
Outdoor protection detection circuit abnormality in your Hitachi Air Conditioner can be caused by Outdoor PCB abnormality, or error in wiring to outdoor PCB.
Why does my Hitachi YUTAKI S80 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.
