Hi guys

after abit of advice....during maintenance i found that the indoor unit had no power to it. on further investigation i found that there is power from the isolator onto the outdoor unit but no power going down the comms wire to the indoor unit. im holding the outdoor pcb board as suspect, anyone know of any other things i can check before i go ordering a new board?!

thanks
