What am I doing wrong?

[whporwil]

I have a 2017 37rb. Today I tried to figure out which breaker the fridge is on. Since what's written on the panel is not accurate I thought I could turn each breaker off one at a time while my wife watched for the light to go out, never happened. I am in a campground hooked up to shore power and I did not try the breakers on the inverter side. What am I missing???

Thanks

You do have a Norcold, correct? Your refrigerator's control circuits run on 12-volts, the 120-volt feature is just a heater that makes the absorption refrigeration process function, as does the propane flame when AC current is not available.

Robbbyr ‘s right! Switch to 12 volt (dc) only and then pull the dc fuses!

You will have a 120-volt AC breaker associated with your refrigerator feeding an outlet located in the lower outside refrigerator access area. This circuit provides current for the refrigerator's 120-volt components that operate the heating element the refrigerator can operate on and also power certain icemaker components. You may have already found out that the unit will not make ice if operating when you are not plugged in or not running the generator. This refrigerator outlet may be on a circuit with other items (outlets) also part of the same circuit.

If the refrigerator controls are on "Auto" and you are plugged into shore power, the refrigerator will be running the refrigeration process on AC. When it is working this way you could shut off the breakers one at a time, and when the correct circuit is shut off the refrigerator should switch over "LP" (propane) operation.

What Rob said or turn your control from auto to A/C and then it will show an error when you flip the breaker Les

Thanks guys! but where is the 12 volt connection to my fridge. I see two cords in back one for the fridge and one for the ice maker.

I have attached a couple of pictures depicting my fridge, your should look similar provided you still have the original Norcold unit installed.

The first picture shows the red and white small-gauge wires that are my 12-volt supply, red being positive (+) and white being the ground (-). The 120-volt AC supply wiring is a much larger white "zip cord" style wire with three conductors.

The second picture shows where that 120-volt AC cord is plugged into the receptacle mounted on the forward wall of the refrigerator compartment.

I hope that helps you identify your wiring!
