Norcold fridge troubleshooting

Trying to determine if my dead fridge issue is as simple as the thermostat control located inside the fridge.

I think I need to close 3 circuits:

The Thermistor
The On/Off switch
The temp dial

Thermistor is easy, other 2 are my concern.

Which combination of Brown, Black, Yellow and Red do I jump?

Thanks in advance.
