Hi all ,


I hope this is right place to post ive got an error on a fujitsu unit that i have come to service

Inverter to PCB Comms Fail, has any one else ever come across this problem and if so if you can point me in right direction what might be wrong .

I'm assuming this is obviously the out door unit problem but as fujitsu tech help is closed for me at the min i could do with a bit of help .

Many thanks in advance .
