    Why do you suspect the accumulator?

    More details about the problem and we may be able to offer some more detailed analysis to help you find a solution.

    I agree with JP on this.

    First you should verify that there is in fact a flooded condition...and not just assume flooding just because you see frost. What the suction superheat?

    Secondly, if there is a flooded condition here, the accumulator won't cure it. It's only intended to handle intermittent surges of liquid.

    Let's hear some numbers.

    x4, I had a unit with the same symptoms a couple of months ago, and it was flooding back, pumping the oil out of the compressor as well, turned out to be the wrong undersized txv. New TXV gave it full load.
