Baz maybe the Vitrifigo has the Triple core/Small type Condenser with the 120mm Cooling Fan I think it is, whereas our 13 yr old Waeco has a Full Length External Condenser from the Top to the Bottom exactly like all the Old Household fridges used to have before Cleanskins came into being.
Apparently, the motor in the fan is what is called 'brushless' with three wires - those types of motors are almost universally used by model aircraft enthusiasts.
Anyway, I ignored the yellow wire and connecting the red and black to positive and negative but it fails to run the fan.
Applying the multimeter to everywhere shows that 12-Volts is going where it is supposed to, even into the fan leads.
So, is it possible to run a three wire electric motor on just two wires?
As I have cut the wires on the fan and soldered a two pin plug onto it I am unable to return it to Jaycar. If there is no way of making it run on two wires it looks like I'll have to buy another fan - say Jaycar's YX2522.
I am heading to Geelong on Saturday and was hoping to have the installation finished before then. By the way - Geelong are forecast to have a maximum temperature of 40-degrees on Friday - that would be a good test for how well the fan works. Luckily the temperatures are supposed to drop to the high twenties for the next week.

Hi Murray,
If the fan is not working connected red/+ve and black/-ve I would say that more than likely that the unit is faulty. I have fitted/replaced quite a few of these over the last 13 yrs and that has always been the correct connection colours.
Cheers Kev.

Just a check, entry can be deleted by the Mod.
I thought if a new entry on an old post "Grave digging" was made it would resurface to the most recent page??
Longweekend was having some issues with his fan mod install and required help but needed to start a new thread, this will test if it is required!

Hi All
Just found this on ebay. Maybe this will help those having problems with fridges not cooling. Lots of good feed back from another site but no personal comments
Yep you are right Kev, it does.
I bought all the components listed in the site www.dreampod.net/boroma/fridgefan.html but the fan does not work with the wiring as shown.
