RESIDENTIAL REPLACEMENT RECOMMENDATION FOR 4 DOOR NORCOLD

Recommended Posts

Has anyone replaced a 4 door Norcold fridge with a residential fridge and would like to share the brand and model of the residential fridge along with the approximate cost for the entire job including the new fridge -- would appreciate any input and info as I'm getting estimates from $3,000 to $21,000 which seems to me to be very unusual.

Thanks, Gary

Gary,

Suspect part of the wide range of estimates is that in many cases the battery and electrical system must be upgraded to accommodate the residential refrigerator.

So, let's start by your telling us:

Battery bank size (in amp-hrs @ 12 VDC).

What inverter or inverter/charger do you have?  Is it MSW or True Sine Wave?

Another cost variable is what cabinet modification is needed to accommodate the new refrigerator.  This may include closure of the outside access door area.

Also, one of the other cost variables is how you will get the old refrigerator out/new one in-- removing a windshield, for example is more expensive than if it will go through the door.

So, until more detail is known, I would expect a wide range of quotes.

What type inverter do you have and how many watts? The newer coaches usually come with a pure sine wave (PSW) inverter and older ones came with a modified sine wave (MSW) inverter. Many of the residential fridges will not work well, if at all with a MSW, hence this is an important question. I currently am using a Samsung with a MSW and it works very well. In preparing for a residential you will need to find a fridge that will fit into the space that the old no-cool is in, or with any modification necessary to make that happen. Another must is to look for a fridge that will require as few amps as possible to work for you, this is because the higher the amps required, the larger inverter and the larger the battery bank you will need. I know that some of this is redundant to Brett's post, but I was typing while he was posting.

This is not a plug for homedepot, but this is the newest updated version of the fridge that I am using. https://www.homedepot.com/p/Samsung-33-in-W-17-5-cu-ft-French-Door-Refrigerator-in-Stainless-Steel-and-Counter-Depth-RF18HFENBSR-2/302577277

As has been stated. Size on all fronts.

Measure your opening, height, width an depth. Then find a unit that fits within those measurements. I would suggest looking at a Samsung since they work on both pure and modified sine wave inverters and draw very little amps.

Next check the size of your inverter. You will need a 2,000 watt min. 

Then check the available amps in your battery.

As I said it's all about size.

Good luck and ask if you need more help.

If in fact you need all the work necessary for the higher quotes, or even the $3000 quote, you might consider replacing the current fridge with a 12vdc/120vac compressor fridge. My experience is that they work well, can fit into the opening left by removing your 3-way, and cost less than the $3000 you're being quoted. A couple of companies make really nice 12vdc/120vac units, including Vitrifrigo, Nova Kook, and even Norcold. If you already have the necessary electrical upgrades to run the residential fridge, than all this wouldn't necessarily apply, but if you are looking at having to upgrade battery bank, inverter, etc. then I'd suggest at least taking a look.
