Diag/ system not cooling (middle unit). Found compressor trying to c9me on but can’t due to failed capacitor. Replaced 80/5 cap but found evaporator is starting to freeze a bit and pressures look low (70/240 45 SH). Showed customer and he would like to add refrigerant to get system cooling properly. Preformed preliminary electronic leak search but did not find any leaks where I checked today, need to follow up to install permanent capacitor and finish preforming leak search. Let customer know we may need to add dye if I can’t find it at that time. Customer would like to have that scheduled for 2 weeks from now so they can see how the pressures hold, currently at 110/295 with SH 16 / SC 9. MN- 50ZHB060—30TP SN- 2910X95797 9/29 - Returned and put on permanent Turbo200X capacitor and followed up and checked pressures and they have held up pretty well since we added refrigerant so customer would like to hold off on adding dye at this time.
