A Norcold NX641 series frig needs 1.2 amps @ 12 volts to power the control board. The control board must be active to run the frig on gas or electricity. The frig requires 3.0 amps @ 120 volts plus 1.2 amps @ 12 volts to run the frig on electricity. If you turn off 12 volt power to the coach, the frig will not work gas.
