Has anybody installed or had any experience with a marine style 12 volt refrigerator? I’m proposing installing on in my GMC

We looked at them, too.

We use a 120v 3.1 cu ft mini fridge. They are 190 bucks at either the Orange or Blue home improvement store.

We already had the inverter, so even if the only last a couple of years, they are 1/5 the price.

If the Xantrex inverter had not been in the parts coach, I likely would have put in this:

Although there are a lot of Danfoss compressor driven truck the nits out there now at attractive prices.

FWIW, the 2.8amp draw at 12v is about 1/4 what the inverter draws to power the cheap fridge.

Peter,

Before the depression, I quoted the installations of several of those. Novacool and another that slips my mind. The best I could do through my suppliers was still not enough to sell any of the jobs no matter how much the owner wanted them. The more attractive package were the separate evaporator and condenser and I should remember the manufacturer, but it is late. Sailboats are hard pressed for room and those had an advantage as they could be retro-fitted to an existing ice chest.

The power consumption was still an issue.

When our No(r)cold went bad, we bought a dorn reefer (two door) the same volume as the original and a cheap inverter. The power drain in only a little higher than the Nocold, but the the cost for the inverter and the two door with real freezer (makes ice over night) was enough lower so we could still buy the new tires.

I am interested in several aspects of this as well. We would like to do something about fridge in our coach. We still have the original Norcold 12v/120v fridge. But it no longer works on 12 volts. I do not currently have an inverter on the coach. For lots of reasons, I do not want a propane fridge.

I could probably find other things to use an inverter for, but... We rarely dry camp. I would like to be able to have the fridge running while driving, and possibly for an hour or two while stopped for dinner, etc.

For lots of reasons, I do not want a propane fridge.

I have read several posts about people using the small ac only dorm refrigerators. Some posters have been more forthcoming about the type/size inverters they are using. Are people using true sine wave inverters more satisfied with their ac only fridges?

How big an inverter do you need to start these fridges? Do you need a bigger inverter if you are using a MSW vs. a true sine wave inverter?

As for me, I am considering either a 12 volt only fridge, or the apartment fridge with an inverter. I have pretty much decided that if I go the inverter route, it will only be with a true sine wave inverter. But then the question becomes how big is big enough? The 12 volt fridge is expensive but efficient; the true sine wave inverters are not cheap other, but may have more utility for other appliances.

I have read Rob Allen's write up about the original fridge, and agree with most of his reasoning. One thing that has changed since he wrote that, is I see a lot more of the dorm size fridges with yellow hang tags less than his 262 KWh rating these days.

Lots of questions, but mainly interested in what type inverters those who have ac only fridges are using?

Thanks,

Ah Paul,

You were the one that might need an inverter.....
Get me off-net at matt(numbers seven-three two-three)tze at gmail dot com and we can go around or even schedule phone time and I can save you a world of missteps (assuming I can still remember all of those we made).

Paul,
I lost the magic smoke from my original Norcold. I will NOT have any more
propane refrigerators. I decided to fix what I had.
I started by purchasing a 400 watt invertors. I did get a pure sine wave
unit, not because I needed it, but because I wanted it.
Then I bought a 120 to 24 volt transformer and a $2 relay from Radio shack
with a 120 volt coil. The relay normally sends 12
volts to the inverter, but if 120 volts is available it switched to that.
The 120/24 volt transformer takes either power source and
supplies the reefer. I even whacked the old wires off the old power unit so
I could easily trace back what I had done. So far I've
never had to. The whole deal seemed too simple, so I showed my wiring
diagram to Ken Henderson and asked "What have I
dome wrong?" He said if it works and gives no problems, you're good to go.
Oh yes, the inverter has an extra outlet that I can plug my TV into when dry
camping at Camp Wal-Mart. JWID

Get a small cheap modified sine wave inverter (100 - 300W). Take the 12V wire off the fridge to feed the inverter, and plug the 110V cord of the fridge into the inverter. Get another 30 years out of it.

The Norcold must have been low of Freon if it failed to cool, prompting you to call it a "Nocold". I am sure you considered bypassing the thermostat to prove that the thermostat was not the problem.

My 1970s vintage Norcold dual voltage will just keep dropping the temp in the box until the thermostat tells it to quit. When the fridge wasn't getting cold, the thermostat was shutting off the compressor too soon.

When I started messing with it, the thermostat wouldn't let me set the fridge compartment any lower than 42F or so until I modified it to go lower. Now I can set it so the fridge stays between 37 and 38F with the freezer around 13 - 15F.

And nobody sells door gaskets for it, so I had to putz with the one that was on it (using the CFO's hair dryer to heat and flex it) until I got a decent seal.

I installed a Norcold DE-0061 AC/DC. Fit right in the original opening. Works great. We have had it for about 6 months. No problems at all. It had been reported that they are noisy, not this one. Great warranty also.
