Fridgidaire Refrigerator

Has anyone paid attention to power consumption the fridge uses when on inverter power for extended periods by viewing it on the inverter remote set to the amps setting for 20-40 hours worth?

I have 520watts of solar and for the most part this fridge NEVER shuts off. I've seen it use 0amps probably 2 times for around 10minutes, and I watch it a lot.
It will use 4-5a a lot of the time, 8-11a most of the time. The second someone opens the door it will jump to 18a, then instantly back to what it running at when closed.

It likes running at 18-22a for quite a while too. I have caught it on a few occasions sucking a whooping 52amps!!
When I actually catch it at 52 I shut off the inverter to cut power to the fridge, then when I turn it back on it doesn't go back to 52amps

If I leave the fridge off for 5-10 minute the freezer temp will rise from 0F to about 20F. The fridge temp, though, will remain unchanged. It will then take 30-40 minutes for the freezer temp to get back to 0 with the unit running around 8-11amps. I see no reason for this temperature rise in such a short time.
I have even manually raised the temp, example, freezer from 0 to 4F and fridge from 36-40F...then the fridge will shut off but only for about 5 minutes. Then it turns back on to the 4-5amp draw.

If it would actually shut off like my house fridge for 20-40minutes every few hours then I wouldn't be using so much precious battery power while boondocking.

Anyone?

Hearing the real high amps, I wonder if it has a frost free feature that uses heat?

Maybe it wouldn't need to go into "frost free" if it would actually shut off once and a while.
I'm wondering if it is stuck so tightly in its little cocoon that it's getting no air circulation and it has to keep the fan running because of the heat built up behind.

The only way I could test that theory is for late fall to hit up here... If the sun is beating on the slide it must be really hot in there.
We've had 0 rain here for 2 1/2 months and temps mid 80's to high 90's.
Very unusual. It's like the desert.

Most residential frost free run 80-90% of the time it's just the nature of the beast. Your unit at home probably does exactly the same thing, but your not that close to it all day to notice like you are in the RV.

Defrost cycle is usually every 8 hours.

JMO but I don't think a residential refrigerator and boondocking are practical combination.

I have read stories of people buying a Pinnacle only to later find out it has a residential refrigerator and they would not be able to boondock as they wanted to. The salesman neglected to inform them of this drawback.

Ya..90% for sure.
I can get 2 nights and 3 days with 520watts and 2 T-105's. And that's with a couple hours of tv too.
I would get the 3rd night if I had 2 more batteries.
2 nights was what I was after.
But if I get two days of cloud then I'm done.

I knew the residential wasn't the best choice, but it is the best when I'm gone for a week with shore power and food.
I only dry camp a couple times and a couple 1 night stop overs.
I didn't think this fridge would run so often though.

Of course you have solar, but JAYCO says 16-18 hrs on two batteries for the fridge.

Mine is cooling, but I think it's acting goofy. Grumpy is probably right though, if these things are designed to run 90% of the time then that's what it doing.

I don't think anyone with 2 12v dealer supplied batteries is going to get 16 hours with the fridge. Maybe... but they surly won't be putting in the slides after, or lifting the rig back in the truck.
My 6volts are under 12v after 12 hours.
