Replacing Norcold with RR fridge

How do you run a Residential fridge off the whole house inverter when the inverter didn't power the 2 way Norcold in AC mode. Can I just hook it into the ac feed to the microwave? The inverter feeds that when turned on. Or how to convert the ac plugin behind the fridge to get AC when the inverter is on. That ac plug is hot when plugged into shore power but not hot when inverter is powering the RV.

    If the inverter didn't work on the 300W draw of the absorption fridge, it's doubtful that it will meet the start up draw of a residential compressor fridge. You may have been referencing the way things are wired and not the "didn't work" aspect of power demand.

    Yes, you could use the circuit for the microwave. You would have to change the circuit wiring in the load center to operate off the microwave circuit.

    An alternative is to add a second transfer switch into the load center, this additional transfer switch would power up the refrigerator receptacle's circuit.

    Finally, using an extension cord to power the fridge may be the easiest solution.


    It was designed not to have ac power at the fridge when in inverter mode since no one would want to run a 2-way gas/elc fridge on electric.

  • Unless it a huge micro and already stressing the size of that circuit, that will work fine.
