Residential Fridge Energy Usage

Our Norcold died a few months ago and I replaced it with a residential fridge that would fit in the hole.

I really wanted something in the 10 cubic foot area but all were too tall so I settled for a West Bend 7.4 cubic foot, still bigger than the Norcold.

https://www.amazon.com/gp/product/B0C1PL78ZH?th=1

$288 at the time.

Once installed I put a Kill-a-Watt meter on it. That was 2718 hours (113.25 days) agoi. In that time it has used 44,400 watt-hrs, so that makes an average power consumption of 16.3 watts, .13 amps at 120 VAC 0r 1.3 amps at 12 VDC.

Of course that doesn't take into account the inverter losses when boondocking or on the road, but it is way lower than I imagined. And, of course, this is also through a Florida winter. I am sure it will be much higher during the Florida summer.

So just some real world numbers for the brain trust.

Not bad price.

Mine draws .9 amps when running. I keep back of ice in freezer and really drops the draw.

That power consumption is very good. Comparable to a DC fridge.

The Amazon site says it uses 345kWhr/year
You used yours almost a third of a year (113 X 3 = 339days)
345/3 = 115kWhr in a third of a year for spec and you used 44.4kWhr in a third of a year.
You used a third of what the specs estimated, yes, pretty good!

Any idea as to how that 1.3amp/hr compares to what the Norcold may have drawn in same condition?

We really wanted Residential at the beginning, but kind of got spooked on what they did to the batteries. The only thing I don't like about our Norcold is the door swings open when making hard turns. Speed not a factor. I have yet to see a professional way to lock that door. Only solution is to not put drinks on the door which defeats the intended purpose.

I have been trying to find the largest residential fridge possible with a footprint of 27"L X 27"W or smaller. Height not a factor. It would go in the Garage to replace our 34 year old GE 24cuft that it just will not die. It runs in the garage with temp hitting 110 degrees

Remember, my numbers are average draw and through the winter - we'll see what they look like come summer.

An absorption fridge pulls about 3 to 4 amps AC when running on 120 VAC. I have no idea how that translates to average draw but I suspect the ON/OFF cycle for an absorption fridge is at a much higher percentage than a residential fridge.

I have tried to avoid a residential fridge. A friend of mine had a Fleetwood Class A DP. Whirlpool residential fridge. Compressor quit and was told by Whirlpool there was no warranty due to being in a MH. So he bit the bullet, had windshield removed so he could get it out and a new one in. Installed a LG. A year later it quit. Both the techs that came out from Whirlpool and LG claim residential refrigerators are not made for constant periods of non use. Ie; parked in driveway for weeks at a time turned off. Is this not the case?

We never turn off our RV fridges.

Some years ago I measured the electric usage of a Norcold 1200 and it was over 300 kWh per month. Adsorption refrigerators are very energy inefficient. Switched to residential and have never looked back.
