Unit running at arrival. I put measure quick on a tested operation. My suction pressure was at 111 and staying right there and the suction line temp was at 65 with a super heat of 30. I pumped the refrigerant into the condenser. With both valves close, I had no pressure on the suction side but still had 220psi on the liquid side. This with the liquid pressure not movie and high superheat and line temp told me that the TXV was not opening or closing. I replaced the TXV under warranty and tested operation
