OK I got a 3 way fridge out of a older rv. I turned it on while it was still in the rv and it began to get cool.  Now that it is in my garage it isnt working when I plug it into 110 volt.

Is that all that is required to make it work?

Seams wierd that it wont do anything now after it started to cool in the rv.

thanks for any insight

Takes a 12 volt supply probably hard to tell without brand and model number 

good luck

Demo, Like Clifford said, you also need to hook it to a 12V source to power the circuit board. It won't operate on 120V alone. Hope that helps, Will

Yes, it takes both, 12v is for the circuit board, won't work without it. Also, if it's a Norcold, check this link, http://www.norcoldrecall.com/ to see if there is a recall on that particular model.

I just hooked the fridge up to 12 volt and to 110. I could here it start up this time. I am going to give it a few and see what it does. Thanks for the input.

Thanks Bob. 

Can anyone tell me what kind of regulator do I need for the lp? Or are they all different?

Would the stove from the same rv take the same regulator?

I dont have access to the rv to take anymore parts off of.


Sorry for all of the stupid questions.

We just got our first Norcold 3way fridge.  So far I am not impressed.  It is an older unit.  It takes hours to get  cold.  The freezer gets really cold but the fridge part isn't all that cold.  Is this just the nature of the beast?  We use it an 12 volt or 100 volt.  We have always had an apartment size 100 fridge before.  Maybe I expect too much from the Norcold.

Don, clean the flumes Norcold will freeze the milk in the bottom when right sounds like you have a unit going bad if so I have a place in AR that makes good replacement units at good prices and they ship www.rvfridge.com Greg is great to do business with give him a call he will answer any questions on the fridge


good luck

Don't try to cool an empty frige, fill it with cold jugs of water, beer, soda, anything but air, and it will cool nicely.

A very cold freezer shows it is working but the freezer space is much smaller and easier to cool down. However, I keep one gallon of ice to put into the freezer for the first cool down when it has been off for a while.

Before leaving on a trip I always fill it with water jugs and stuff then cool it down with AC, takes just a few hours in anything but extremely hot weather. I find that cooling down with AC then switching to LP is the quickest way.

We will make sure the vents are clean.  Maybe,  I am expecting too much.  The apartment fridge is cold in about an hour once I load it with cold stuff.  It will stay cold all night turned off, but the Norcold didn't seem to be cold after being on 12 volt all night.  The freezer was still cold though.

It won't get very cold on 12 volt plug in to 110 and leave on for about a week it will start working better those fridges will last for years if they are working everyday sitting idle is the worst you can do for one

good luck

To work well they need to have the correct spacing from whatever backs up the fridge.  If you are testing it sitting in the open it won't work as well.  Needs the correct chimney effect. 

Good luck

Ir will never cool down on 12V only. It won't even stay cold on 12V even if it is cold to start with.

12V is for emergencies only or maybe during cold weather. Hot weather, forget it.

Amen.....

I thought it would be a great idea to run on 12v and save on propane when we did some 700+ mile days. I thought my fridge was bad! 12v is worthless! Propane will freeze it up but sometimes it still struggles in very hot weather. Cool your stuff ahead of time if possible.

I bought an indoor/outdoor thermometer at Walmart that has a remote sensor that I keep in the fridge. Now I know how hot the driver's area is and if the fridge is staying cool.

BarnOwl,do have a 2 stage regulator or 1 stage the 2 stage regulator are not bad about freezing unless the vent hole is turned up instead of down or if they are installed on the liquid side instead of the vapor side and fwiw not to start a war here but the regulators are supposed to have a cover  to help with that problem also

Since we don't have it hooked up to propane,  I guess we will make sure it is on the inverter for 110.  We are considering installing a small propane tank to run it in case of emergencies or when the inverter is off.

If it is the propane regulator I would guess it is a one stage. I should clarify that I can freeze the fridge if I turn it down low and don't open the door a lot, and then especially if it is cold outside.

It is a 1979 Dometic, and though not perfect and requiring me to keep tabs on it, it works. A real PIA to light and remain lit if it has been off for a while. That's where the thermometer becomes invaluable.

Can I get a two stage regulator at the hardware store? Or is it a rv surplus thing?

As Cliff says, forget about running it all the time with the inverter.  The power required is high because it is a resistance heating coil, nothing like a house frige.

LP is so efficient and cools so well, uses very little LP.
