    strange defrost procedure !!



    Hi
    how r u
    Samsung floor standing split ac
    classic non inverter
    R22
    29000 BTU
    220 volt

    here the temperature reached -2 C
    in heating mode
    normally unit go in defrost to melt ice on the outdoor unit
    what i know is
    when the thermistor in outdoor unit senses low temp its call for defrost

    what must happen
    just indoor fan and outdoor fan turn off and then 4 way valves revesre to cooling mode while compressor keeps work
    until ice melt then 4 way valve energized to heating while compressor keeps work

    in my case
    what happen here
    when ice severely collected on the outdoor unit
    the compressor off
    after many seconds 4 way valve reverse cycle in to cooling mode
    then compressor then run
    after ice melted compressor go off then after seconds 4 way valve revers to heating mode
    now why compressor go off for a while
    instead of continuous work as in other split ac unit
    best regards

    Some units do stop the compressor on changeover.
