Question Refrigerator Conversion

We are in the process of purchasing a 2004 Intrigue Ovation 42. The current owner converted to a residential refrigerator from a two way rv type. It's a Samsung 20 cf French door. He says it won't work with the current 2000 inverter. The coach only has two 8d house batteries. I would think it would need more batteries to be able to run the refrigerator, right? Has anyone out there done this swap on a similar set-up? Any advice would be greatly appreciated.

More battery storage would be useful, but might not be the cause of the problem. What type of inverter is it? Some appliances work better with a PSW (pure sine wave) inverter instead of a MSW. (modified sine wave)

You didn't mention exactly what model of Samsung refrigerator you have, but if you Google the model number, you'll find out what it's power needs are.

Refrigerator Conversion

It has a modified sine wave inverter. From what little I've read, Samsung refrigerators should work with this type. That being said, I'll dig a little deeper. Thank you for the input!

If it's a recent Samsung it should run on a 2000W MS inverter. There are a lot of people doing it. It could be that he never wired the fridge to run off the inverter. A lot of the non total electric rigs come from the factory with the RV fridge not being connected to the inverter.

This is a guess, maybe when they installed the new Refrigerator, they used the same 110 volt circuit the old one used. That circuit doesn't go though the inverter. Try plugging the Refrigerator into a circuit that comes out of the inverter (wall plug in the kitchen) to test.

Are you seriously thinking of buying a coach when the fridge is not working with inverter power?
If the owner really wants to sell it he will do whatever he has to do to get it working.
(Maybe the reason he's selling is because he tried and can't).
BTW There are more coaches for sale than there are buyers.

We don't know the model # of the Samsung or it's power requirements, especially on start up. Could be the inverter is off, not hooked up to the outlet the fridge is on, etc. I also wouldn't buy the RV until the fridge is demonstrated working. That could be another $1800 needed to use the RV. Two batteries is minimum for using a household refrigerator, at best.

The two 8D batteries and a 2000watt inverter will run that fridge (assuming the batteries are not dead).

I agree with the comment that the existing electrical outlet for the OEM LP/Electric fridge is not wired to the inverter circuits. One way to tell is to look in the separate electrical panel with the circuit breakers that are wired to the inverter. If you don't see one that is labeled 'refrigerator,' I suspect that is your issue.

Also agree I would not purchase that coach until the existing owner fixes the issue.

Your right. I'm just speculating like everyone else. I know that non TE MADP's of the same vintage as mine came from the factory w/o the fridge connected to the inverter. As the OP stated, the original owner replaced the gas/elec fridge with a residential. It does require more effort to switch the circuit over to the sub panel to run off the inverter. I have also read on this website where some people elect to do so intentionally, because they feel it is not necessary for their situation of going from point A-B.

There is nothing wrong with the way the coach is wired, it is the way it came from the factory. Behind the refer, there is an outlet where the ice maker was plugged in. Try moving the new refer into the other side of the plug. If that doesn't work, it is a very simple task to change the wiring to run off of the inverter instead of running through the inverter like it does now. I had to do the same thing to get my Samsung to run off of the inverter.

I only have 2 8D house batteries and it runs the refer just fine. To get the refer to run from the inverter should cost no more than a couple hundred bucks if you pay someone. If you do it yourself then 20 bucks.

The Samsung will run on a modified sine wave inverter, no problem

A big thank you to all of you that provided information. As for buying an RV with a question about running the fridge on the inverter....we really like the rest of the features, and the price, so feel the fridge issue won't be a deal breaker.

I had my Samsung installed going on 3 years now,like dons2346 said just move the wiring to make it work with the inverter. I only have (4) 6-volt batteries and we did 5 days at the FMCA rally with no power, yes we had to run the gen-set about 2hrs in the morning and in the evening. This should give you an idea on what to do, this is not my install but it is the same setup.

If you feel that inverter running will be an exception vs being plugged into shore power, then yes the X's 2 8D's should cover you. Another option is to add a smaller inverter, but carefully size to handle compressor surge start up, and PSW too. That 2000W inverter is consuming more battery AH's at idle then you need... So a smaller dedicated PSW inverter could save you quite a bit of AH's overnight - IF that is important to you.

Best of luck to you on the coach,
Smitty

Samsung setup

I have a Samsung RF18 refrigerator in my 2005 inspire. I'm running it on my 2000 wat MSW inverter. You need to change the power from the 110 shore power panel to the inverter panel then all should work fine.
Good luck.
