Hi guys

I have a Daikin system , yuk!!!

Master RXYQ14M8W1B
Slave RXYQ10M8W1B

Master unit has a faulty inverter compressor (windings down to earth) , just replaced it and the inverter PCB , after 10 mins of test run got an L8 fault , reset and checked phases going to inverter all balanced but this time it faulted a lot sooner with an L5 fault didn't get a chance to check anything else while it was running , rang Daikin just told me to check gas charge going at that tomorrow. Any other ideas , I did run the system with the new inverter bypassed and the slave unit ran , didn't really perform very well tho but it's inverter didn't fault out. Any ideas ?
