Did you get any joy on manuals for this?? Did you get any joy with this I have one here at the mo that just runs the fan inside! sits at room temp!

ย 

I have one too, and same as m109a3uk, it sits at room temp just circulating the air in side. I thought it was the controller so I swapped that out but still the compressor does not kick in when a lower temp is set. Any insight gratefully received.

Same as yours, turned on with the circulation fan running and displayed the ambient temperature. After much investigation of the controllersย menu system I concluded that it had either been locked or was so old/damaged that it needed replacement.

I have built control panels for breweries and itโ€™s a very simple wiring circuit inside so it was a simple install of a cheep replacement. Works a treat now!

would a photo / wiring diagram help?

m109a3ukย it doesnโ€™t sound like your compressor is being triggered. The air circulation fan is on all the time and wired to the on/off switch.ย the chiller blower is on a separate circuit controlled directly by the temp controller (PID) so if this isnโ€™t kicking in and not getting coldย then there is no signal from it to the blower or the compressor. Therefore (same as me) I suggest getting a new controller and experiment with that..

No need to get anything more expensive for a number of reasons. First they are cheep at ยฃ15 and have all the functions / features needed.ย no point in spending 40 or 50 quid on something and finding itโ€™s the actual fridge thatโ€™s broken, you can always by a more expensive one later.

also, these STC 1000s have a 10amp relay, to cope with any surge,ย theyย have a heating function, and are compatible with the basic NTC temp probe already installed in the fridge.

Just wire up as per my photos below -ย terminal block used as a temporary solution.

Thatโ€™s great news! I reckon the controllers, or some of them, are locked.

Any way good to hear yours is now working. What temperature have you managed to get down too? Iโ€™ve only achieved 2 degrees...

also, are you using a female circular power connector? If soย what is the part number and manufacturerย please?

cheers
