What is causing an expansion module error on the compressor which I have to power reset to start compressor back up?

With luck, you can just r/r it, maybe clean contacts if just re-seating doesn’t do it.

Failing that, check the module for obvious problems like burnt components, bad solder joints, etc.

Good luck.
