OK,, one other thing,,,,before I replace the blown controller, I need to ohm out the 4 pin grunert compressor. I can't find anywhere info on what my pin to pin readings should be. Anybody?

James, thanks for the manual,,,Will be calling AER tomorrow to see what the windings should ohm out

windings should ohm out

You should also check the windings to ground. Sometimes called "Megging".
The compressor housing should be well grounded.
A winding bleed to ground will pop the fuse.
