Copeland Scroll makes long squeeking noise when shut off
I have heard it "squeak" a little right when it shuts down before but ignored it as another odd noise from a scroll. Today I was right in the yard and all sounded normal but when it kicked out, it made a squealing noise for about 20-30sec after shut off. I am puzzled and to add to that, I felt the line set and both liquid and vapor were cold. Liquid was sweating. The liquid usually runs a little warm..
I am wondering if this sucker indeed was running in reverse or what the heck. It is a heat pump but that should all be disabled. I know for a fact I cut the entire reversing valve out and not like these pumps are made to run in both directions.
