I have problem with inverter compressor of AJY108LALH and AJY126LALH (FUJITSU V II VRF SISTEMS).
The unit AJY108LALH is a master unit in systems with two slave also AJY108LALH. This system work 4 month, and then inverter compressor of master unit is block out. Error code on the outdor unit is 93.1 (inverter compressor start up error), and thats the only error in history mode. Slave units work properly. We changed PCB on the master unit but inverter compressor did not started.
Same problem we have on the outdor unit AJY126LALH. This unit was work only 4 days, and then inverter compresor is block out. On this unit we have same error code 93.1.
When we measured PCB and IPM board electricly all parameter's are OK.
Both system's have required amount of refrigerant, and there is no leakage of refrigerant.
Has anyone had similar problems.
