Re: Liquid Pump Low Dif
As far as I remember nobody mention that this issue happen when compressor turn off. Even when it off, it takes time to cool oil in the oil cooler. So it will take time for liquid to fill up the return line.
I believe in sudden change of the load. It can happen if several evaporators off or make up solenoid close.
