    Sounds like plugged dryer or cap tube.

    Check for the nameplate inside the freezer, top left of the box near the front. Likely a plugged cap tube, probably killed the original compressor, and whoever replaced it overcharged to compensate. These are an easy conversion to txv.

    340 head is to high. Clean coil well, check sub cooling. If you are restricted subcool will be high
