Norcold 3 way fridge

[chrismct]

I have a new to me 1999 Holiday Rambler vacationer with the stock Norcold fridge. The fridge should run on AC when hooked up to shore power or the gennies running correct? I get error codes of F and A, checked the fuse and is good.....kinda stumped at this point.

They were able to operate on propane, 120v or 12v. The heaters were 12v and there was step-down transformer to run them on 120v power.

NO RV 3 way absorbsion fridge has a step down transformer. They have a 120 element for 120 operation and a 12 volt element for 12 volt operation. They still make 3 way RV refers, they are used in small B and B+ vans. And some Truck Campers.

They still make 3 way fridges. https://thenorcoldguy.com/n3150-5-3-cubic-ft/

Can you find the model of the refrigerator, I think the identification label is inside the refrigerator door. With the model we can probably get you some better ideas what to check.

definitely pull the outside panel off and take a look. Just use a nickel or quarter to turn the latches 90 degrees and pull out. There should be a 120v household style outlet behind the door. Make sure the refrigerator is plugged into this outlet.


The refrigerator requires 12v DC for both AC and DC operation so check all the fuses in the breaker panel as well as on the back of the refrigerator. If the refrigerator is plugged into the RV check the outlet for power or try unplugging it and running a separate extension cord from the house to the refrigerator.

The 12v power is needed to make the control board work. Without it, nothing will work.

Interesting. MY 3 year old truck camper has a Dometic 3 way in it. Propane, 12 volt or 110 volt and no transformer. The boiler has a 12 volt Mullion Heater and a 120 volt Mullion heater.

Of course it's coming out this year and getting replaced with a Marine Dometic compressor fridge.

Tired of the inefficient gas fridge.

IMO just run your fridge on propane.

F is no pilot light or no gas to system. ensure you have gas and also that you have either the Button on Auto or Electric. Post back, will find you a troubleshoot chart in a sec.

The A is no AC to the unit. Ensure it is plug in. Take the panel off the back on the Outside and ensure it is plug in. Also you will have to bleed the air out of the system to get it to light the first time. Turn on a cook top burner and light it and at lease two more and let them run for a few minutes. Post back

Do you have 110 volts to the rest of the RV. TV, Microwave.
