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.
