Kegorator Wiring - Bypass therostat.

[Crusader-Rob]

I just go hold of a fridge, and I have an STC-1000 to fit with it, but this is fitted externally, rather than inplace of the thermostat.

I just want to bypass the existing fridge stat, and just want to confirm the if i join the brown, which is live, and loops to the light. and join with the blue/white wire, which is also joined with the orange wire, which i believe is the compressor.

Basically I want to bridge across just confirming this is correct. Can someone help me out.

Why?

If you set the fridge to as cold as it will go then your STC-1000 will switch it on whenever it needs to be. Or off if that's the case. You shouldn't need to mess with your fridge's wiring.

What Barry said. My STC-1000 is external. With fridge thermostat set to coldest it takes it down to 0 deg without any problems.

My fridge for fermenting has had the thermostat bypassed and works a treat. I know from experience some fridges wont get to lagering temps as the range of the thermostat fitted is too high. its a kegorator and a lagering fridge basically. 

Plus when i was dicking around looking to see how the fridge worked I broke the thermostat...

Anyone else want to confirm for me?

You probably need to find a pet sparky (there must be one around that would do it in exchange for beer!). Most people are not going to be able to recommend how to wire the fridge from your description. You need someone with a multimeter and a bit of knowledge to help you out...

Is it a standalone fridge or a fridge-freezer?

Others have mentioned that you could set the fridge to the lowest temp and mount the stc1000 externally which lots of people do, provided it can get cold enough. I have a fridge that wont get cold enough - though its a fridge freezer that pumps cold air from the freezer to the fridge to cool it, these ones may be more prone to such problems...

You could achieve setting the fridge to coldest electrically by wiring across the thermostat such that the fridge always runs  and then mount the stc1000 externally in an enclosure that the fridge is plugged into.  although you would have to be careful that it was only ever used with the stc 1000.

I think that what you mention in your post basically makes sense  if you want to mount the stc 1000 in the fridge itself - like in a cutout on the side (though i dont know what the colors mean or if they are standardized). Basically you want to run the live wire to the STC 1000 cooling relay and the compressor drive wire to the other pin on the cooling relay. its probably more complicated if its a frost free fridge (is it?). Not to sure what to do in this case without all the details eg full schematics.Maybe use an RCD the first time you run it just to be on the safe side.

Yeah. I wouldn't really try anything without checking the wiring diagram first.

Right, so my old mans a sparky, and before the rugby, he poped over and had a quick look, its all wired up now with the stc externally, and those wires joined together in a block.

Just as I'd thought.
