Bingo that's the exact part I was thinking of. I read that some AC systems have a variable expansion valve. If there are moving parts there is something to fail. I don't know anything about it though: is it electrical? Solinoids ? If so could be a fuse or connector or controller.

My AC wasn't working because the low side sensor wasn't completely plugged in. That was a good day when that Discovery was made.
