Chiller not cooling

[ndjfb00]

I had a quick look on here and whilst there are similer queries none are as per my question but I'm sure this has been asked before!

At minus 3 outside air temp chiller isn't cooling, should I enclose ( a little) the top of my open chiller to create slightly intake air? Many thanks in advance

If it isn't cooling, get it serviced by a refrigeration engineer. It's money well spent.

Ah I should have said, its fine when it's not so cold, my guess is the chiller is not designed to be in such a cold environment ( eg a shop stock room) hence the query on maybe creating a micro climate

if it's not designed to be outside at -3 there is probably the issue.
It's like not all domestic fridges or freezers are suitable to go out in a garage because of the low temperature.

Ok I'll go with my idea!!!

So just to close this down, by enclosing the air intake area above ( not airtight!) This somehow creates an air temp the chiller is happy with.....this may help someone else or maybe I'm unique in using an adapted chiller

or put a small panel heater on top of the chiller

If the temperature is -3 and its a fridge unit the thermostat is probably not switching on the cooler. Most fridges operate between 0 and 5 degrees C.
Is it not coming on at all or is the fan running?
If the fan is on its the thermostat setting.

Hi, fan was running but not the cooler, seems OK now with 'some' restrictions applied to the top, aware this shouldn't be done due to reduced air flow but I'm hoping it will warm up soon

The restriction on top is probably keeping in heat from the evaporation coil and or condenser, which fools the thermostat.
Try sticking a thermometer in it, it should be between 3 and 6 C. If your outside temp is at or about that level it won’t switch on because it doesn’t need to.
