Hi im new to this forum so I will start by saying hi to everyone.
In have Refered to this forum many a time for info so I thought I would take the leap and join up.
A few weeks ago while I was off sick another engineer from my company was called out to one of my sites to an R22 k series daikin vrv he diagnosed that the compressor was faulty and also that the inverter board had blown.
Fast forward to last week and I change the compressor and inverter board and when I've come to run it up I got an L0 fault after looking at this thread http://www.refrigeration-engineer.com/forums/showthread.php?8742-daikin-L0-inverter-problem&highlight=daikin+l0+fault and doing the checks with the help of daikin tech I condemmed the main pcb and ordered a replacement.
Today I fit the replacement pcb and it came up with an E1 Outdoor PCB defect fault:(
then Daikin have said that i must have been sent a defective board and had to order a new one.
I then replaced the new board with the old one so that I could leave the system on emergency mode until the new board arrives and i am now getting a u9 fault.
By this time i could no longer speak to tech and called it a day.
Has any one got any ideas on what may be causing the u9 fault.
Thanks.
