Hi guys
help needed. I have a daikin vrv system running on r22 not sure of model but I keep getting a LC fault every 1 to 2 weeks . At this stage I have swapped over every pcb board on the unit with the unit next to it to eliminate which pcb boards at fault .the only thing I haven't changed is the noise filter board.fault came back today and also on a totally different unit .does anyone reckon it might be there power supply dropping a phase every now and again.or am I missing something .these are very old units but any help would be great.
cheers
