My bud's 2013 trailer has a Domeic 8 cubic foot fridge without a thermostat, it's labeled as having an "Automatic refrigerator temperature control"" but it doesn't seem like a very good idea to me, the fridge kept freezing stuff while we had it out for last week.

Also, when this particular model is running on propane there's no light at all on the top panel; I'd expect it to at least have the AUTO and/or PROPANE lights lit up similar to the last 2 trailers I've owned, 1 had a Dometic, the other a Norcold.

Has anyone run across a Dometic like this? (Don't know the exact model number)

The Auto Temp Control DOES have a thermostat and thermistor....just doesn't have Temp Setting Adjustments

The Thermistor (Temp sensor) attached to FIN can be moved to adjust overall fridge temps

Move thermistor UP for colder
Move thermistor DOWN for less cold


In your 'friends' case....DOWN

In AUTO the fridge controls will select AC Power (Priority)
If AC Power becomes unavailable the fridge swaps to GAS
It will swap back to AC when AC Power is restored

If you select GAS Manually the fridge will only run on GAS ...no swapping back to AC Power

CHECK Light comes ON when GAS Fails to light off and prove a flame is present.

Several Dometic Models use the Auto Temp Control
This Manual covers some of them


Is it time for your medication or mine?

You can get one of these eyebrow boards that has the adjustable temperature. It is a direct replacement.

OK Thanks, I didn't know about the thermistor on the fin, will see if he does.
I do know how the "auto", gas, AC thing works though, but what I'm saying is none of the indicators light up like it your pic, that I've never seen before.

(... and this is regarding my 'friends' trailer BTW, mine has a Norcold with a thermostat and working indicator lights)

He is saying when you are set to propane only there are no lights.

It only turns orange when propane fails to light.

OK, that seems weird though.
We never have hookups and our fridge is always running on propane and always have lights on. (But then again I've never had a fridge without a thermostat either)

My Dometic fridge is same as you described, no lights when on propane only. We spend most of our time RVing off of the power grid thus we just set fridge to propane, plus it tends to cool better in that mode. Fin temp control can be replaced with a dial type temp control, freezing up of fridge may indicate fin temp control has failed or possibly fallen off allowing for constant cooling to occur.

We have had both brands of RV fridges, they cool pretty much the same. What's paramount is that they are properly installed, many RV builders do a poor job not allowing for enough ventilation on the rear of the unit. Many turn to residential fridges primarily do to poor performance, anything to assist air movement for proper airflow behind fridge would indeed enhance cooling prowess of the unit.

Fridge has a 'thermostat' ----ALL fridges do
That model just doesn't have a means of adjusting the temperature range

When ON propane the only display lights would be CHECK and you dont; want to see that one ON

No lights...fridge cold ...all good

*Yes there should be some indication that fridge is ON other than a fault light when it is NOT working. Stupid design!

ISTR the Dometic we had last year (since replaced) had the check light come on first, then it went out when the gas lit, which you could hear.

That fridge was acting up so flame would go out and the check light would come back on and you tried again. Lots of fun with that old fridge (from 1991)--last seen at the city dump being kicked off my truck! I did enjoy "giving it the boot" [emoticon]

Yes, that's exactly what happened. I sent the link to this thread to my bud, he said the white thing musta fallen off the fin, he didn't know where it was sposed to go. (he just got the trailer)

I added inside fans to my Norcold, just gotta make sure I
don't pack beer on the top shelf by the fan cuz the toggle switch with poke a hole in them! [emoticon]
