Thermostat switch

Yes there is from Jaycar KC5476 $33.00 Tempmaster fridge/freezer control unit, works well use one for a Waeco CR80 fridge which had a faulty mechanical thermostat. It could be used to switch a fan on/off. Cheers Daryl

I wanna know the same thing, i want to install one inside fridge to blow cool air around, but would like it to turn on and off at certain temps.

Cant find anything of the sort.

Thanks dbish...
Seems that it's a kit that I'd have to build meself... EEEKKkk...

Glad you have one (did you build it yourself..??) cos now I can ask you questions:
How hard/easy was it to build..?
Once built - Is it easy enough to set the controls re on/off temps..??
Can it be programmed to "on" at 5deg and "off" at 2deg - or is it more crude than that?
Thanks for the info

Jedo_03, Yes it is a kit requring a hand full of components fitted to a printed circuit board requiring soldering, The fulldescription & construction is in a magazine Silicon Chip (may be on line) Feb 2009 issue, it is adjustable temp by a variable resistor (trim pot) The cutin/cutout (diferential temp) as per orig circuit was to narrow 1deg, Changed 10M resistor betwean P1 & P3 on the integrated circuit (IC) to 2.2M this gives 3Deg cutin/out range. Daryl Un fortunately not member of this site so cant post pictures.

Please be aware that the danfoss 12v feed is a max of 500Ma continuous, a higher current is allowed for a max of 2seconds during start otherwise you will get fan overload cut out error of 2flashes on the led. If its a Waeco Fridge freezer it already has a fan & internal globe running of it. If you disconected the internal lamp you may ba able to run another fan .These figures are from the Danfoss compressor data sheet. Daryl

Joc and dbish...

Ummm - well I'm not really game to start dismantling the Waeco..
But thanks anyway
