Fridge

[Legacy Posts]

Hi All
On my last trip out I hit very hot weather(38C)90plusF.
My fridge would not perform properly.I remembered a post here on fans removing heat from back of fridge.I was lucky and had a small 110 volt fan and tried it.Worked like a charm,Fridge back to normal.
On way home I bought 2 --12volt fans and will be installing same.1st fan draws 0.43amps and little fan draws 0.23amp .

Big fan will be used at back of fridge and small fan will be placed in fridge and tested to see if air circulation inside will improve performance.

Somewhere I read that a RV Fridge is considered to be working well if it keeps the interior of the fridge 40 degrees cooler that outside.
What happens if the outside temp hits 100??:conf

Owen,

I just got back from a campout and the temps outside were closing in on 100*. I only had it turned up about 1/3 of the way, it was stuffed full and the butter was very, very hard. Had I wanted to freeze everything in there, I have no doubt at all that I could have done so if I cranked up. Since mine is only a two way, I ran it on propane.

Of course the A/C was on in the trailer and I never left the door open for very long, but I've had equal success at home when the A/C wasn't on and I was getting ready for a trip.

My 14 year old Dometic keeps things as cold as I would like. Colder, if I'm not careful.

Owen, I can attest to that! We just made two crossings of the Mojave desert, the first with temperatures ranging from 100 to 125 degrees. And that 125 was for several hours. We keep a remote thermo in the refrig, and 40 degrees below ambient in the trailer is about the best it could do. I'm not implying that the refrig ever got up to 85 degrees, simply because of the time factor, but it did register close to 60 degrees. Meanwhile the freezer was always solid, well below freezing. The obvious answer to me is to install an inside fan like Ches is suggesting to move the air around in the refrig. and also will install one of the little computer-style pancake fans at the outside vents, also as Ches suggests. Ches, do you plan to mount those on the high or low vent, and blowing which direction?

Also that desert heat probably contributed to two of our ''beloved'' Carlisles blowing out on this trip! But that's a whole 'nother story.

Hi!

The 40 degrees is what a small electric cooler like Koolatron that you can put in the car can supply. I don't think that we can apply this rule to a RV refrigerator.

Here is what I found on the Koolatron web page:

A Koolatron cooler can maintain its contents at a temperature approximately 40 to 45 Fahrenheit (22 to 25 Celcius) degrees lower than the temperature of the surrounding air. It is best to load pre-cooled food or drinks into the cooler. As a rule of thumb, it takes about one hour per pound of material loaded into the cooler to bring it from room temperature down to maximum cold.

At a temperature of 80 deg.F (27 deg.C.) the contents of the cooler can be maintained at approximately 38 deg.F (3 deg.C) (Normal household refrigerators are usually maintained at 45 to 48 deg.F. (7 to 9 deg.C).

At a temperature of 90 deg.F (32 deg.C.) the contents of the cooler can be maintained at approximately 48 deg.F (9 deg.C).

Hi All
I have now placed the bigger fan at the top end of fridge area to blow out hot air and hopefull draw in cool air from bottom.This bigger fan moves lots of air and cost me about $10.00 CDN

I tried this on holidays with a small 110volt fan and fridge really improved.

My freezer was also ice cold and my meat was frozen solid.My butter was real soft.My wife suggested removing freezer door and let cold air into fridge area.I thought I would wait on this one and see how my ideas work.I THINK little fan circulating around should really help.:wave

The ''Fridgemate'' fan (#F110 at www.camperschoice.com) might be helpful for the interior of the refer. They claim it will run for 30 days on 2 D-cells. Same source has a 12 v. refrigerator coil fan which is thermostatically controlled to go on at 110 degrees F (part #F152.)

Also, www.Jameco.com has 12 v. computer-type fans with built-in thermoswitches that might be useful--two of them are rated for 40 degrees C and 50 degrees C, respectively, which is probably in the correct range for the back of the fridge compartment. (They're only about 1/3 of the cost of the Camperschoice fan.) See part #166959CP.

Hi George! Welcome home.

I want to thank you again for giving me the idea of running down the road with a remote-temperature-sensor in my refrigerator!

(By the by, I forgot to tell you when we met up in Colorado that Pam threw the remote sensor out the Suburban window, somewhere in Kansas.)

Joyce discovered she had lots in common with Pam at that meeting. (But not going so far as tossing the thermometer.) I made her reach into the back seat all the way across the Mojave desert to keep checking the thermometer---the sensor just didn't react when it was up on the dashboard, even with fresh batteries. Probably because the back of the SUV was so jammed with stuff!

But I think I still need those fans----many of our trips are to, or through, really hot parts of the country.

Chester - I have been looking for a fan like the larger one you show in your picture. Where did you find it? I have looked at the local RV parts place and Radio shack with no luck.
Help!

Sam, try this link to Jameco Electronics, look under DC Brushless fans.

Hi All
As you all know I put a fan in back of my fridge to remove hot air.I have now put in a baffle to direct all incoming air to go right to and over cooling fins at top.With fan and baffle this should really add improvement to cooling.:wave

Just curious-- Why don't RV fridges have noisy compressors like home fridges?:conf

[Legacy Posts]

Because they won't run on LP gas.:lol

Kitty ... home refrigerators use a power-hungry compressor to move the refrigerant through the system.

RV refrigerators use heat (propane or ac/dc heating element) to vaporize and move the refrigerant through the system. (Also feature absolutely no moving parts!)
