Found Reach-In Cooler temp control contacts stuck open so the condensing unit wouldn’t run. I jumped it out and condensing unit started but the cabinet temp was struggling to get cooler. The expansion valve is bad and is restricting refrigerant flow. Per Corey they would like the parts qwp (expedited freight). 02/03/21 Replaced TXV, filter drier and T-stat. Pressure tested with 200 psi of nitrogen for 15 minutes. Pressure held. Released nitrogen and puked deep vacuum. Turned on unit and observed temp dropping. It not quickly. Adjusted TXV and unit slowly started coming down to temp. Would have liked to see high side pressure a bit higher than what it is, but that’s all I can get out of it. Unit did come down to 34° and shut off. Observed a second cycle. Unit is running good at this time.
