Dometic CFX-50 runs continuously and won't freeze.

Interesting development. It seems to be working now. We had a storm and the power flickered. Now I can see it to -8 and it gets there. Things are frozen in all parts of the cooler too. That's with a heat advisory in effect and my garage being in the 90s. Guess it just needed a power cycle?!

Did you switch it off for a day or two ?

I did not. The power clicked off and and back on almost instantly. Seems to work fine now.

Based on the behavior of both my ARB and My CFX somethingorother... 28 maybe?? You shouldn’t expect 8 L of water to freeze very quickly at all. Maybe days or weeks when set near or just below freezing. Maintaining already frozen will work, but without forced airflow, you simply can’t remove energy fast enough to accomplish frozen solid.

At -18*c or 0*f that water should freeze within 6 to 10 hours, My ARB 47L will freeze 1 litre bottles of water and soft drink in just a few hours in around 2 to 4 / 5 hours Max.

Wow !! I have to buy one of those ’fridges, maybe two !!
Seriously, something is way out of sorts with those Ah values...

Have a read of my post from back in April this year and see the two photos I posted That test was done in temps of around 18*c, and those pictures show the Ah and the Watts used in a 24hr period,

Actual Fridge Power Draws

I'm attempting to guesstimate my total power needs for our family when we move FT into our FWC and I can't figure out what a fridge will draw. Dometic states "Energy Consumption 12VDC (Ambient@90F, Internal@41F) 0.85 Ah/h" which I believed to be, on average we can expect under those conditions...
