Funny thing, most modern refrigerators use DC motors for their compressors so that they can run at variable speeds, so there's likely an inverter that you could bypass if you know the appropriate voltage. The DC ones for RVs are the same internals, just without the inverter.

Correction: they still use AC motors, but those motors don't use line AC. It goes line AC > rectifier > DC > inverter board > variable frequency AC to run the compressor motor.

Most RV fridges just use DC motors, but there are some that use VFDs and AC motors.

Have we moved to BLDCs yet?

No they don't...they use AC motors and a VFD to control the speed.

I mean it's probably labeled, right? How hard could it be?

Exactly. Find a hole that's black and a hole that's red, and stick some wires in there. How hard could it be?
