Fridge OFF But Still Cold?!

Howdy,

I was at my 2019 Sport 22FB today and noticed that while the 'Fridge is certainly off it is a bit cool.

Plus I'm in AZ and we have had plenty of 90+ days since I'm sure it was off. I had left it on for a while but sure it's been off for at least 3-4 weeks.

I noticed my battery was down to 40% too (I have factory solar).

I turned off the power with the switch and will see next time I visit but is there some sort of parasitic charge via the Fridge?

Thanks,

Rounder44

The heating of the ammonia in the cooling unit is what creates the cooling of the refrigerator. When I lived in Phoenix the freezer walls were cold during the summer from the heat on the cooling unit. My thinking is that the heat is causing the refrigerator to cool.

That's pretty crazy!

It has been warm but not summertime hot.

In fact a lot of cool days and in the 70's-80's recently But I suppose even a few hours could activate it if this is the cause.

Thanks,

So you are saying that only the hot ambient air temp is "causing" the fridge to "cool" ???



This would be a first in modern physics IMO!

Fridge off and it is cooling correctly?

Everyone should post actual air and fridge/freezer temps -- this chain of causation may have a few weak links! [IMO]

Are you saying in effect that everyone who has an AS fridge in a hot climate only has to turn the thing off to enjoy free cooling?

Most Airstreams have an absorber refrigerator. Although it might seem logical that heat can't cause cooling, here is a definition that counters that logic:
"An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process."

Sounds like it's time for some cool science experiments!

As long as the refrigerant has some source of heat, it will cool the fridge. I would be surprised if the ambient heat is enough to cool the fridge a great deal, but not surprised if there was some measurable difference.

I'd guess it was ~60 +/-.

Freezer fins were cooler....

Weird...

Of course I understand the physics, but look at the fine print of what the heat source is usually:

"solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems"

NO WAY that ambient heat alone in any location will cool a fridge down to anything below the ambient temp !!!!

Unless Merlin comes along to create thermal energy from nowhere, it just ain't gonna happen!

The fins felt cooler to the touch because that metal absorbs the heat from your skin faster than the hot ambient air, thus your mistaken perception of the metal being cooler.

GIGO!

Get a temp reading of the fins, and you will see that everything is about the same temp as the ambient air temp inside the fridge/freezer!

No heat source . . . no cooling . . .

The mind is a powerful deceiver!

Like what, 5 degrees Fahrenheit maybe? So if the ambient temp is 60 F per recent post, then the fridge/freezer will "cool down" to 55 F?

If you want to call that cooling, be my guest, but maybe the fridge would be better off making warm tea instead of iced tea!

How is Airstream planning on fixing a fridge which is turned off?

Maybe...

BUT that doesn't explain how the inside ambient temp is lower as well too! How the plastic is cooler!

I also had a friend with me and we both noticed this.

Hey maybe the fridge is just incredibly well insulated and sealed! BUT....I'm sure it has been in the 90's for at least a few days since I turned it off and it was downright uncomfortable inside on several occasions when I visited.

Past 2 -3 weeks have been cooler temps over all though... It's AZ We've been in the 50's and 90's the past month! Nights as low as 40's but averaging ~55 to 80....

Weird...

The fridge is a well-insulated cooler of sorts, and will maintain cool nighttime interior ambient temps, even if the trailer interior ambient temp goes up 30 degrees or so during the day. Put a good store-bought cooler in the trailer as a parallel test, with no ice in it.

Please measure things carefully, and keep a log. It is highly likely that you are perceiving cause-and-effect relationships where none exist IMO. The added cooler without ice should confirm the same patterns from the AS fridge.

The mind plays tricks like this all the time.

No need to belabor the general point. Without accurate temp readings, we have reached the end of the road.

Good luck,

Peter

Please read the entire thread, Tom. The owner turned the fridge off! That is why the fridge does not work, because the act of turning the thing off was intentional.

Not a fixable problem. In fact there is no problem at all !!!

The question directed at the Airstream rep was to see if they are paying attention, or just blindly replying to some random post.

Ye Gads!
