How Cold Can Your Fridge Go?

[KJRitchie]

Hello,

How cold have you measured your refrigerator. We just acquired a 2008 Classic 25 with the 7 cu/ft freezer. My fridge displays the temperature on the outside. So far the best I've seen is about 32 deg F on setting 5 and it seems accurate when compared with thermometers I've put in the main compartment. The trailer was in covered storage, on electricity, level and the ambient temperature was in the 70s. My 4 cu/ft Casita fridge could get down to about 25 deg F. I would prefer to have my fridge be colder at the highest setting so I could lower the setting to 3 or 4 and have a little leeway for summer travel. I have the thermistor located in the middle of the fin..

What is the coldest you've measured your fridge?

On 4, I'm at 34 degrees. Haven't measured on 5, but have frozen stuff in the crisper bins.

As long as the Shiner Bock is cold, I don't care.

Depending on how good the engineer who designed that board was, it could just be that that it's smart enough not to drive the main compartment down below freezing. I realize that's giving Dometic a lot of credit, but it's worth a shot.. have you left it to its own devices at 4 and at 3 to see what temperature that gives you? And is the rear fan on or off?

Never been able to get ours any lower than 48.

Mine's a Nova Kool 12vDC/120vAC that does not use ammonia or run on propane. This past weekend, I discovered that setting 3.5 was too cold because it partially froze the T-bone I intended to grill for dinner. Had to defrost the steak before putting it on the grill, so it ended up being the next day's lunch instead. Setting 3.0 is about right on mine, for this time of year. Later, come summer, I may have to set it to 3.5 again, or even 4.0 to keep the fridge at an ideal 40°F.

Thing is, how cold the fridge gets depends on two things: what you set the thermostat to, and what the outside temperature is. The hotter it is outside the box, the warmer it will be inside the box, for the same thermostat setting. Thermodynamics in action. That's one reason why the dial has number 1~5 and not degrees printed on it, because the same setting doesn't always produce the same temperature inside the box.

I have had difficulty getting my frig to get cold when the temp out side was warm. It is a new replacement. I removed the upper cabinet to find the installation was not done properly. The frig was not venting properly to the roof vent. After correcting the air flow and installing a solar fan in the vent cover, wala, fixed!

Sorry to hear your fridge is junk.

The max safe temp for a fridge is 40*F,that is NOT the ideal temp it is the max safe temp(according to several sources).

If I am not careful mine will turn into a freezer. I have had it down to 20 degrees F before I noticed. Not bad for a 40 year old frig that only works on electric.

That's the ideal temperature to serve American beer, though!

Could you please share with us where you got your solar vent and possibly a photo of it installed?

Thanks, Dan

Don't know what kind Airsdreamers used, but Marinco makes pretty good solar vents under the Nicro brand: [URL="http://www.marinco.com/product/3-stainless-steel-minivent-1000"]

The fan I installed in the vent cover can be found on EBay, Item number:
350699422239. I bought mine at a yard sale and it looks exactly like the EBay one. The one I bought had a brand name on it but I can not remember it. I am sure the EBay one is a knock off but if it works. I wish is was MADE IN THE USA! It has a switch on the unit. I bypassed the switch and wired another switch into the upper cabinet so I could turn it on and off as needed.

I will supply a picture of the installation as soon as I am able to get a ladder etc..

This the finished product, very similar to the fan Protagonist mentioned earlier.

If you highlight the part number for EBay fan in my earlier post, it comes up in goggle then EBay
