Samsung resdental FR18 refrigerator

Hi
we are the new owners of a HC 331 RL.And have just finished winterizing the water system including running pink rv fluid threw the ice machine. After doing this we have discovered there is no way to turn the RF18 residential refrigerator off ? the book just says if your not going to use it for an extended period of time to unplug it ?? pulling it out to unplug it does not appear to be a simple task?
So my question is ??? once I unplug the 50 amp power supply to the fifth wheel will the refigator continue to run on the batteries until they run down ??
Thanks

1. I turned mine off using the control buttons, google the owners manual or there is a video on you tube. 2. Only if the power inverter is turned on. Turn it off to, or do it the old way, lift the positive terminal on the battery, best do that anyway cause the propane detector is always on. If your not going to be using it for some time that is.

I would suggest lifting the negative cable if you wish to remove all loads.

From the standpoint of Physics, it’s negative to positive. The particle responsible for electricity, the electron, has a negative charge. In, for example, a battery, the negative terminal has an excess of electrons and the positive terminal has a deficit. When the two terminals are connected, the electrons begin flowing from the negative to the positive (then back to the negative, internally in the battery).
From the standpoint of electronics, however, it doesn’t matter. You can imagine the electricity flowing from negative to positive or from positive to negative, and (in every case that matters to electrical engineers) you’ll get the same results every time. This is why some applications to electronics were discovered even before the charge of the electron was known, and why many electronics textbooks will talk about electricity flowing from positive to negative. Also, in electronics diagrams, things like diodes and transistors are drawn as though electricity flows from positive to negative.
When discussing positive to negative flow, electrical engineers will sometimes discuss positively charged particles flowing. In this case, they don’t mean protons or positrons: they’re talking about the flow of “space lacking electrons” or “electron holes” – gaps in space where there are no electrons even though there could be. These electron-hole “particles” are not actual particles; they’re simply a tool used to help imagine positive-to-negative flow.
As more of a physicist, I tend to think in terms of the negative-to-positive flow of electrons. However, you can just as easily imagine everything in terms of positive-to-negative electron-holes, if that makes you more comfortable.

Or just lift the positive it is what most people understand.

It only took one sentence to tell me to unhook the negative. That has worked well for me for a long time.

all good info but all I want to do is turn the refrigerator off. and leave the batteries hooked up so we can move the slides in and out a few more times for last minute projects before winter sets in

Press and hold the refrigerator and ice plus buttons at the same time for 5 seconds. This will place the refrigerator in DEMO Mode and your indicator light will say O F, or OF F. The lights inside fridge will stay on, but the unit will not cool, and freezer will not freeze. DEMO mode is basically for displaying the unit in a store, but essentially turns the unit off. Hope that is what you are looking for. Do the same button push to turn unit back on for cooling.

Just flip the circuit breaker off for the refrigerator in the beaker box and turn off inverter.

On mine there is a red switch in the battery compartment that shuts off 12V to the inverter thus shutting down the refrigerator, double checked it. Doing that and making sure everything else was off, I can leave the 12V switched (in the convenience center) on so the solar charges the battery's the only other draws are the smoke and carbon-monoxide detectors and the solar more than covers that.

if you are winterizing disconnect the batteries.


do you want to remove batteries and keep warm and charged?

If all you want to do is to completely turn off the res ref......go to the inverter and near it will be a receptacle where you're frig is plugged in....just unplug it and it's OFF. There is NO plug behind the frig on mine.
Turn OFF the inverter also by looking in the compartment where the batteries are and turn off the inline switch mounted on the wall. That's the way it is on mine , but I do not have the same unit as you. Hope this helps. When I first bought mine I had the same question and called the factory and talked to an "expert" with 35 yrs experience in RVs. He told me to "just roll it out from the wall and unplug it"!!!!! True story. Hope this helps....or neg to positive, or positive to neg?? lol

Thanks this is the info I was looking for when first posting. this is our first RV with a residential frig so I wasn't sure how all that worked. there is a plug for the frig you can see behind it but it looks they put the frig in place and then put a piece of trim under it that would need to come off before just rooling it out lol

It won't "just roll out" cause it is anchored to the wall.....otherwise that monster would tear up the whole RV before it crashed out of a wall!!!!.

miket49,
As a side note, you do not need to run the "pink stuff" through the ice maker. Blow the line out with air, separate the feed line under the slide and let the water drain. Since you already put antifreeze through your ice maker, be prepared to make pink ice for awhile next season.

As a former Aviation Electronics Technician in the Navy I understand "hole flow". But the truth behind removing the negative cable is that there is less spark potential there. Lead acid batteries vent gasses which can be explosive. Less spark, less chance of blowing something up.
Just saying.

even after taking the two anchor screws out in front the frig is will not roll out because of the molding in front which runs half way across the kitchen slide

If you leave the batteries connected you will surely drain them unless you have means to keep them charged even with the Fridge disconnected. Batteries don't just die, they get murdered.
