Where to mount a fridge fan thermo switch

  • #1

Hi,

I’ve got a fridge fan fitted to the top vent, and wanting to make it thermostatically controlled. My question is, whereby is the best place to mount the thermo switch (like these), and what temp switch is the best to buy?

You are reading: Where to mount a fridge fan thermo switch

Should I mount it on the top tube nearest to the flue and go for a 60 deg switch or mount it at the opposite end to the flue and go for a 50 deg switch? Hoping someone has been down this path before….

Hi Andrew, just had look at these switches and they are normally closed so when temp is reached they open, this is the reverse of what you need. At least from what I can make out, they are for thermal overload not activation. I am also curious on how to connect thermal switch.

Cheers

If you do another search of jaycar with “thermal switch” it shows normally open versions as well.

I bought one of these probably 4 years ago, still haven’t got around to fitting it yet!!

I followed the info here, needed to move the thermostat around a bit till I found a spot thru trial and error whereby the fan was not constantly on. Hope the link helps

Great post Mike, thanks. From the wiring diagram it looks like the inside fan remains on constant, is this directly?

Cheers.

Is it easier to get the manufacturers kit or is there a big saving? They are also available from plumbing supplies, they are quite often used in gas heaters. Tradelink have 65 & 70 deg switches

i have fitted the same setup as shown in the above link. The 70 deg thermo switch. I will get a picture of where i have mounted it and post it for you. I think at the current time it is to close to the burner. I have to check the temperature on the tube further down as i think it is cutting in to early. will do some more checks and let you know. Other than that it writings very well just switching on and off. Did not do internal fan though.

G’Day Burnsy,

Sorry for the late reply, have been busy as anything. mate I didnt do the internal fan mod, only the outside one which has made a significant difference to the fridges operation in hot weather.

Cheers

hello, ive heard that you can fit computor fans to the rear of the fridge to get heat away and this makes them work better has anyone done this ?

Hi,

this thread is a good place to start:

http://www.expandasdownunder.com/threads/quiet-fridge-fan.9619/

If your fridge vents are on the off-side of the van, you might as well want to investigate adding a shade cloth to keep the sun of the vents to keep the incoming air cooler.

If you have any questions or want more information, I am happy to under the name ofsist. I have added a fan to my Penguin in the past month or so.

typeest regards

If you browse thru this thread under the name of well you should find pics and details http://www.expandasdownunder.com/threads/drovers-/

I have fitted about 6 vans up but have progressed to just sticking the fans to the inside of the top vent with Sikaflex which writings a treat, a 70 deg thremo switch mounted on a spring clip which just slips onto the fins is about the best way to fit them but if you have to go out and buy all the gear you will probably better off just to buy the kits which are about $65.

Hi,

I’ve got a fridge fan fitted to the top vent, and wanting to make it thermostatically controlled. My question is, where is the best place to mount the thermo switch (like these), and what temp switch is the best to buy?

Should I mount it on the upper tube nearest to the flue and go for a 60 deg switch or mount it at the opposite end to the flue and go for a 50 deg switch? Hoping someone has been down this path before….

hello, im just getting it right here …the fan is pulling heat away from the tubes ,eg pushing hot air outside and writing a flow from the bottom..Yes ? .also i saw an article where they made plastic shelves or bins for the fridge so it held the temp better when the door was opened i thought that was a good idea

Here is a photo of my fridge fan installation. I purchased a 55 degree Celsius normally open (NO) thermal switch. I usaged 2 stainless steel tool clips purchased from Bunnings to mount it to the pipe. Works great.

Hi,
I wrote about the plastic trays we usage in Dometic RM2350 in this thread:

http://www.expandasdownunder.com/threads/our-new-jayco-penguin.9593/#post-

The trays have extremely helped with the temperature recovery time after the door is opened, especially around lunch time on hot days.

We found a plastic storage box from KMart ($5) who made a perfect crisper draw for the bottom shelf.
The only mod was to cut away the four dimples (feet) on the bottom so it was the correct height to fit in the space.
The added advantage is that we can fill this tray with all our vegetables in the kitchen and slot it straight into the fridge in the van.

regards

Mike

I am going to do this mod to ours before we head up north. Just out of interest does it help the fridge when running on gas or only power?

@Rockape, cover the gap between the upper of your fridge and the cupboard the hot air will flow into the gaps beside the insulation and thru the cables runs, if you look down the bottom you will probably find open cable runs, give them a squirt of canned foam, not only will the air flow be misdirected dust will get in also…………………

@Hubble80 , the fans will make the fridge run more efficient on all kinds of fuel but the rear of the fridge must be fitted correctly, many are not. A good read of the fitting instructions make it very clear how to instal, can’t understand why the builders can’t follow the directions.

Another gurusan sir. (May under the name of well strike while iron is hot)

What the best stuff to deflect the heat to the vent at the top of the fridge? Will a automobile windscreen defector type of material be ok?

and do you just remove the vent and put it in so who any air access to cupboards is stopped up?
