If you encounter an error while using your Hitachi product, then you might encounter error code E9 on your device’s screen. To fix this error, you need to try a few solutions.
The first solution you can try is to replace the fan motor of your AC unit. The fan motor is located in the back of your AC unit and it is usually a heavy part. You can get help from your technician or technician friend to remove the unit cover.
You need to open the cover by removing all screws that are holding it in place. After you remove all the screws, you need to take out the fan motor. You can get help from your technician or technician friend to replace it.
If you are not able to replace the fan motor, then you need to contact your technician or technician friend so that they can help you replace it for you.
The second solution that you can try is to check for high or low pressure in your unit. High pressure can cause many problems such as damage and leakages on your unit and low pressure can cause issues with the operation of your unit such as freezing of compressors, low power, etc.
The third solution that you can try is to restart the operation of your AC unit. You can restart your AC unit by turning it off and then turning it on again. You need to turn off the power first before turning on the power again.
The fourth solution that you can try is to replace any faulty temperature sensor in your AC unit. This can help you to fix any problem with your air conditioner. The temperature sensor of your air conditioner detects if there is a high or low temperature in the room where you are using it.
The fifth solution that you can try is to change the filter of your air conditioner unit so that dust particles do not accumulate in it and block its cooling system from working properly. You need to change this filter once every six months.
An AC filter needs cleaning more often than other types of filters.
