I just bought a new home w/ lots of fixups... Now, the refrigerator stopped working. I'm somewhat mechancically inclined so I ripped into it. The compressor for the Freezer seems to kick on and work well, but the refrigerator compressor doesn't kick on at anypoint while rotating the control knob from OFF to 10. I can get about 45 degrees from it, but I think it's cooling from the cold freezer (through the wall). Any thoughts on where to start troubleshooting? Ie, which controls, switches, etc to start with? Thanks - Dan
