I have not come across this before.
walk in cooler with 3 evaporators. I'm getting what looks to be a huge pressure drop across the liquid line solenoid valve.
slightly warm on one side frozen on the other. Could it be that the llsv is not opening fully and acting as a metering device ?
I did not do much with the unit because it was over 100 degrees here friday and it was off on head pressure. I removed the 3 shopping bags from the condenser got it running and rushed off to the next call.
