Hitachi RAC E14H2 Errore LD 301 10 times.
Hello friends.
The air conditioner has not been used for several years and as such the compressor parts may be stuck. The external device shows error code 10 times. I have changed the connection cable of the internal unit and the outside unit. The 45 mf/200 vot capacitor is OK. How to start without pcb control? ThanksLast edited by anesti; 07-07-2022 at 10:27 PM.

Re: Hitachi RAC E14H2 Errore LD 301 10 times.
After checking with the lens I saw that the logic PCB and the load circuit PWB were corroded by the salty coastal air. I tried to repair part of the printed circuit, I also made a bridge in the compressor load relay RL1 G4A, and the device started working, but in heat mode. It seems that in conditions without power, the reverse valve works in a heat process. Under these conditions, I installed a 220 volt solenoid coil and the system returned to cooling.I may already have a problem with the defrost process. If I need to completely replace the electronic Power PWB and Main PWB package of the external device. Can I to buy them here on the forum?
