Starving expansion valve/valves causing evap oil logging? freezers are great for that, then when restarted or after defrost termination, TXV is wide open and now warmed oil returns. Wrong viscosity oil? box temp running extremely low, or simply a compressor running/starting problem and subsequent shut-down causing Sentronic time-out trip. Evaporator oil logging likely when all else is eliminated, check or set superheat, sensing bulb tightness/insulation? or new TXV. heat reclaim valve fault?
its basic and simple but can help to the other who is not familiar

Nice video a digital manifold gauge set would allow a more accurate pressure comparison.
