Re: Abnormal serial communication!
It mean that indoor unit doesn't communicate with outdoor unit for some reason (burnt fuse in outdoor, faulty PCB etc...).

Re: Abnormal serial communication!
I'm gonna rule out a bad fuse because the unit does start up for about a minute then shuts itself down and the only fuse in outdoor unit will shutdown compressor when bad, I was figuring bad pcb but which one? indoor or outdoor?
I really hate to randomly replace parts,
Thanks for the speedy reply,
