Last week, when I turned on my Hitachi AC, I observed that the red light was flashing four times and it wasn’t working. So I reached out to my AC technician to fix it. He outlined several potential causes, such as faulty wiring connections, damaged wires, or issues with the outdoor unit, along with other factors that result in the red light blinking. I have shared all the reasons for the Hitachi AC red light blinking 4 times below.
Why is the Hitachi Inverter AC Timer Light Blinking 4 Times?
Here are the reasons the AC technician informed me about this issue.
He said the red light blinking 4 times means the unit is waiting for the outdoor part of the air conditioner to turn on. Like, the indoor fan won't run in heating mode until enough pressure and heat have built up.
The cable between the indoor and outdoor units may be faulty. It is what happens in my Hitachi AC.
It can also happen because of the damaged wiring inside the indoor unit.
A loose connection might exist at the terminal block.
There is an issue with the control board of your AC.
I hope this will help you.
