Hello everybody,
i want to ask about a refrigarator candy cnf-4055a. The problem is that this refrigerator works from 16c and up outside temperature (class n). How can i make it to work at colder enviroment ex. 4c outside.
The thermostat is ranco k57-s2872.
Thanks a lot.

Are you using this machine in a storage area/garage which is unheated?

Stat details here..

If it is outside try rewiring the door switch to keep the internal light switched on. This will generate a small amount of heat and keep a load on the thermostat.

if its just a fridge it will still work at a lower ambient it should do job ok if its a fridge freezer the stat useually runs of fridge and due to low ambient it thinks its cool enough but the freezer will run warm if you fit a colder stat the fridge will be to cold /i dont supose its a twin comp model? by the way is that a 430 or a 426 in picture

if you fit a coolder stat the fridge will get to cold and start freezing the fridge the only long winded way around it is to fit a stat to the freezer and not use the fridge like brian suggested you could lock in the fridge bulb to give some heat but one day it will fail the real options is to make room warmer/ find a twin comp model or fit a freezer stat in freezer the ambient does not effect the performance much of domestic it requires a min 12dc so heat goes in fridge when you open the door and makes stat run
