    panasonic cu-re12jkx-1 error h11 ,no communication



    Hi ,i have a problem with this unit ,i suspect it is outdoor pcb .Is there some component that could the problem and it is replacable ? The whole pcb is expensive and would be better to buy a new unit .I have checked few resistors and capacitors on the com terminal 3 but couldnt find anything wrong .I hear a lot of this units have this problem .
    In one machine like this a had a problem with power module on outdoor pcb and manage to repair it .Maybe someone has a solution?

    Found this:
    If all connections are good, than measure beteeen them on the DC range, and it should be fluctuating between 20 and 50 V DC

    If it is, than it may be a faulty indoor PCB, if it is not, than disconnect number 3 at the outdoor unit, and measure what comes out of the PCB on 3, in reference to number 2,it should be about 20 - 70 Vdc
    If this voltage is not there, than the outdoor PCB may be faulty
