Title: Question about temp controls on a fridge freezer.
Post by: Billythegypsy on November 15, 2013, 12:23:29 PM
Is there a way to separately control the temperatures in the fridge and freezer sections?

I'd like to have the fridge at cellar temperature and use the freezer as a fermenting chamber.

I'm thinking that I'd have to over ride the internal thermostats seeing as I cant use an stc 1000 to control the power from the plug.

Anyone have any experience with this?

You'd need to remove the internal controllers and use two ATC or STC devices wired in their place. Not for beginners.

Im open to correction - I dont think its possible on most fridges.
Because the cooling coils in the freezer compartment are usually on the same cooling circuit as the main fridge - the only difference being that there is a bigger area of cooling coils exposed to the freezer compartment relative to the volume.
I know this is definitely true for most small to medium fridges - so i suppose it depends on the fridge - in a fridge where you can control the freezer and fridge part separately it might be possible to do what eoin says - Ive never actually seen such a fridge-freezer (not saying they dont exist) - Not sure whether they would have 2 separate compressors .... My guess is if you have such a fridge - it will be too good to waste on sitting in your shed fermenting beer.

My advice assumed separate controllers
