Oil flushing out. Same thing will happen again. You need to look for the reason the compressor fails repeatedly. Likely a contaminated EEV from installation. Stuck open, liquid flood back washes oil and kills compressor. Also no need to change the PCB on this occasion. Also, I had that ServiceChecker fault this week. It would crash the program. I rebooted and it was fine. Maybe remove SD card and try another USB port. Hope this helps
I was thinking the same thing. I couldn’t get my service checker to work. I ended up trying a different laptop and now it works. I’m probably going to go back and hook up again.
VRV/VRF Equipment normally doesn't have a filter drier. A canister style filter drier can be added after a burnout to allow for quick filter changes to remove acid. When this is completed it should be removed from the system.

Any info bud on how to check the board to confirm that it is good.

Daikin also wants us o install a suction drier with bypass when you have a burnout.
@@desieranks not necessarily required. Depends on cause of burnout
Software issue is with a dll file, read it. Not a shield issue. Dll might be missing. Simple to fix.
The sticker on the back is so dumb. Do they really think your rep isn't going to tell you about the hidden SD card.
Does this unit not come with LL dryer?
Nope. Think of it as a big multi head Minisplit.
