Samsung success

[lekhuset]

Our new Samsung 197 is in and working great. I will write a detailed description of install with pics soon. We will be changing location soon and I want to use the inverter plug- in. We have a modified sine wave inverter. There should not be a problem as I recall some of you also did this. I just want to verify this. We have had many new refrigerators over the years but none were appreciated as much as this Samsung! Ice within 4 hours of turning on, -2 in freezer and 38 in fridge. Beautiful!

Ours worked fine on the inverter on our first trip with it two weeks ago. It ran about 10 hours on our msw inverter, most of that while driving, and didn't seem to miss a beat.

Congrats!!! Sounds like a carbon copy of my experience!! Right down to the -2 and 38. I'm unable to work on it furthur for a couple of days but I'll be adding a few more pix and final synopsis in a few days. Right now the little beauty is in it's resting place but I need to work on the final mounting etc.
Again Congratulations!!!

Our Samsung 197 has been running on our MSW inverter for over 3,000 miles of travel and seems to be doing just fine. I've been quite pleased with the minimal battery usage while traveling.

After you have used it a bit I would be curious about your temperature settings. We find that -2/38 makes the ice cream way too hard and froze the lettuce. We're running 6/42 which sounds high but the ice cream consistency is just right. We also have plenty of ice. Has anyone else encountered this or is it just our unit?

BTW, I did find information on a Samsung website that stated that if the unit is making lots of ice it will drop the freezer temp below its actual setting. I have seen that effect on the ice cream--if you use a lot of ice and it is making a lot to replace it, the ice cream consistency will get very hard for a few hours or so.

I don't mean to focus so much on ice cream, but it is one of the major food groups and was a primary reason for getting the residential fridge.

Major food groups are important! Ice cream for me and chocolate for the wife. We already tried ice cream bars. They were frozen solid. We were without a fridge for a month so everything tastes good. Thanks for the inverter information. We will switch plug-ins. Should have done that to start with.

Swede,

As the other posts indicate, the Samsung works on the inverter without any issues. The one thing you have to watch out for is the number of devices and their power consumption that are simultaneously operating on the inverter circuit the Samsung is on. Not sure about your coach but ours has the 2000 watt MSW inverter with two 20 amp circuit breakers. One 20 amp circuit is dedicated to the microwave. The other has the Samsung and most of the coach wall outlets. Things like coffee pots, toasters, hair dryers, etc, are resistive heating and can draw from 3 to 11 amps. The Samsung is a power miser and I usually see a 1 to 2 amp increase on my Progressive HW50 display when the Samsung turns on. We just spent time at the FMCA GEAR rally and only had a 30 amp service. I watched things closely and that is how I know the Samsung current draw. I would watch the EMS and the Progressive display and monitor what happened when things turned on and off.

I just wanted you to be aware of the loads you place on the single 20 amp circuit of the inverter or you may be going outside to reset the breaker. This always seems to happen in the middle of the night when you are in your sleeping attire! I have two 110VAC cube heaters in the holding tank area and one of them was on the the inverter. After installing the Samsung I moved the heater on the curb side to the block heater circuit with the road side heater. I also installed two outlets in the bath area that I can connect directly to the 20 amp service on the pedestal. These are for when we want to use electric heaters in the winter.

We are loving the Samsung and know you will also.

Our coach was wired the same way and we changed it when we did the installation. We decided that there was no reason for the microwave to be on the inverter--if we want to run it we can turn on the generator. The circuit for the fridge hadn't been on the inverter previously (the Norcold only needed on propane and 12V) so we swapped the fridge and microwave. Now the fridge has its own 15A circuit and doesn't have to share with all the other stuff.

According to Samsung Q's and A's posted about these units they require ~11A starting current even though they only take ~100W to run. At one time (~ a year ago) Samsung seemed to have no concerns about operating them on inverters. Now they put caveats related to "making sure you have adequate peak current" available. My assumption is that some people have tried to operate them on inverters that were too small and have encoutered problems. So giving the fridge its own 15A circuit seemed like a good idea.

I would like to take our microwave off the inverter also. Without thinking I tried to use it on our trip two weeks ago (the first with the Samsung) when we stopped for lunch at a rest stop. I meant to start the generator but didn't. When I tried to start the microwave it just made a low growling noise so I shut it off quickly. Obviously not enough juice to start it.

Anyone know how I can get the outlet it uses off the inverter? Our microwave is in the curbside slide and the outlet is in the cabinet to the right of it. Our PST is the same as the PDQ models except we have one bedroom slide instead of two.

Jim,

Since the microwave is in the slide like mine, I believe the best way to tackle this would be at the inverter. There is a junction box behind the air vent for the furnace but you still have to get through the flexible cable to the fixed wall. You could run new lines from the power distribution panel to the inverter. Disconnect the private circuit from the microwave at the inverter and connect it using a junction box to the new line from the circuit breaker panel. The other end of that line is from the circuit breaker that was private to the old frig outlet (non-inverter). That will get the microwave off the inverter and on to the generator/shore power. The line that was removed from that circuit breaker is spliced to a new section of wire running to the inverter. The other end is connected to the inverter to the circuit that was previously used for the microwave. Then move the plug for the Samsung from the old inverter outlet (ice maker) to the old outlet that was non-inverter power. That outlet is now private inverter power for the Samsung. That will get the Samsung off of the mix of outlets running through out the coach.

Have fun,

Bob

We stopped using the microwave on inverter after the first few times we tried it. The microwave takes 2-3 times longer to work using power from the inverter. I suspect that's due to the modified sine wave. Now we start the generator before we get into a rest stop and leave it running till we leave. Charges the batts and give full power to run the microwave. When we leave for Texas next month we'll have a better take on how it works with the new Samsung.

Thanks, Bob. I think I understand what you are saying but will have to wait until I get it back home from my dealer's service department to look at it. They are installing a new microwave as the old one is not working right. It shuts itself off after 59 seconds whether on microwave or convection (it was doing that before I tried to run it off the inverter). The dealer said they have no one in the area who works on them so will just replace it. Get to use my service contract for this one.
