    So... What's the problem here?

    Hopefully the picture I took of the DRSA is adequate to provide all refrigerant side data.

    Problem is this:

    Dual temp single deck case would NOT hold temp in LT mode. Did a 'fair' job in MT.

    Tech#1 was out and condemned the powerhead and when that did nothing, replaced the whole TXV. When THAT didn't work, I was called in.

    Cut in a pressure tap and SG on the liquid line to confirm quality of liquid and the pic I posted gives the results. Sightglass was perfectly solid.

    So. Fire away.
