Glenn, just a reminder, the fridge doesn't cool as well on 12 v as it
does on 120VAC or propane.

Well it is cooling....it was 80 degrees inside the fridge, now down to 70 degrees with the thermostat set on 4. So we'll see how it does. Glenn

I have a 74 Eleganza SE & it has a 120v duplex plug behind the fridge just inside the outdoor access panel on the bottom left. Not sure if mine's an early or late build, but it's there.

Well no place to plug the 120 into has been found except across the hall by the water pump swithch..lol..Anyways today the freezer section was 20 degrees so it is working better than it was on the 12 volts. Will keep an eye on it and let it run a day or so and during that time try and make a connection for it under the bath sink. Anyways it's great to have a working fridge even if it has to be plugged into 120 volts, at least it is cold...lol..Thanks, Glenn

There's the rub so far...the 12 volt system, until I upgrade that then I feel it's the weak link in the system. Right now using 120 volts the freezer section is freezing in the 30 degree range and the fridge section is about 40 degrees (not as cold as I like my beer...lol ) so I turned it to the 5 setting on the thermostat and will see where it is at. I have to say the temperature in the camper is close to 90 degrees but I did turn the AC on high so should help the fridge cool. Glenn

Glenn,
You might want to take a look at the door seal on the fridge. If it is leaking, it will run a lot more than it needs to and never get really cold. My original fridge worked OK, but got progressively worse. It didn't fit in with our desire to do more dry camping, so we replaced it with a three way. I didn't see how bad the door seal was until I pulled it out of it's hole and could get a good look at the edges. I still would have replaced it, but I'm guessing it would have worked a lot better if it hadn't leaked so badly.

Hi Carl, well I checked the fridge yesterday evening and it was down to 15 degrees in freezer and 35 degrees in fridge section, so it is cooling well. I turned it down to 4.5 on thermostat but have yet to check it today. So now I have to get a 120 volt outlet put in on that side of coach. I think I can rob it from the box behind the bathroom sink area. When cleaning the fridge the seals looked ok, but will check to see if it is sweating around them. Thanks, Glenn

Glenn,
35 in the frig section is a bit cold and you will find that you will freeze your veggies at the bottom, but it does show it is working acceptably. Mine typically at the coldest set point runs about 39 in the frig and a -5 in the freezer. Ice cream needs to be a bit colder than 15 degs and it will be a bit soft. I usually run ours a 4 setting and the frig run right at 41 degs which is what most home units run at and the freezer is at -1 degs. You can put inexpensive temp indicators in your 2 compartments.

I think that your order of improvements/repairs should be to get the 12v up to snuff first with a new converter and good house batteries. Then try the frig on 12v. If it works fine then there is no need for 120 volts. But if it still does not work correctly, then there is a problem with the 12v side of the frig. You then must decide whether to fix the frig or do as Emery and others have suggested and add an inverter to run the frig on 120v. My original electric compressor style Norcold frig from a '78 drew 6.25 amps at 12volts. A 100 watt inverter should run the frig. But to make sure, measure the AC power draw with a Kill A Watt or similar device. Here is the manual for a Norcold.

Thanks, Glenn This will be the last time I pester you with this.
Do not plug it into a receptacle that could get its power from the Onan.
First, get your converter problems sorted out. Get what you got doing what it is supposed to, or replace it. Then, put the fridge on a 150 - 200 watt full wave or modified wave inverter powered from the converter/house battery. There are only two reasons not to: 1. Inverters are not free. 2. Inverters do not last forever.
Here are the reasons for doing so: 1. If the inverter is efficient, the fridge will use less power on 12VDC than the built-in chopped wave inverter (slower house battery drain). 2. When you run the Onan, even if the frequency is off, the fridge will only see 60 Hz on the inverter (will not damage the compressor). 3. It won't matter if you are driving down the road, or hooked up to shore power or dry camping on battery or running the house on Onan power, the fridge will always be running on its 120VAC input.

Plans for now are to get the 12 volt system updated to todays systems and see how the fridge operates. If it still fails to perform on the 12 volt system then I will look into repairs to the system or inverter to handle the system as suggested. The 120 volt system works and would suffice as we don't dry camp and if I used the generator it would only be to exercise it or an emergency for charging batteries and I would turn the fridge and any other newer electronics off when doing so. Haven't had time to check the output frequency of the generator but wouldn't run tv or anything with the generator operating. I appreciate all the help with this fridge since I had no experience with the dual voltage fridges. I now have a better grasp on how it works and for a 40 year old fridge it is performing as well as could be expected...lol Thanks, Glenn
