Kegs In Danger Of Freezing Help Needed.

[pob]

Plug the freezer into the other plug on the STC - what happens?

How have you the STC wired, pics please.

Hope ye can see this.

You need to tape the sensor to the keg!

Fold up a piece of kitchen paper, cover and tape it to the side of the keg.

Having it dangle like that gives erratic readings making it jump between heat and cool constantly

Not wired correctly

Not all STC's are the same. Plug a lamp in to the cooling socket and see what happens!

Edit: wiring looks fine👌

The display suggests that the current temp is -2.6
The 'Heat' LED is lit which suggests that the logic in the STC is telling the Heating circuit to come on.

If the fridge is running, the COLD Relay may have failed closed.

Remove ALL power - Check continuity over the Cold contacts.
If this is closed you may be able to replace the relay or the STC complete.

Did you test as above?

Also test continuity over the HOT side.

It looks like the Probe may have failed.
Have you tried using another probe?

Unfortunately i have no multimeter atm to test continuity properly and i don't have a spare probe atm.

If your using a freezer and some other heat source could it be you have plugged the heat source in to the cold socket and the cold (e.g freezer) in to the heat? I ask because I see the heat light on your STC panel from your picture.

I did think of that but no i double and triple checked and it's wired right according to the diagram on here. Just in case i pulled it from its container and rewired it from scratch using a new block connector i found. Waiting to see what will happen now.

What I meant was if you had the stc-1000 connected up to two sockets one should be wired to plug-in a heat source & the other to a cold source. It is easy to mix up which socket is for which & end up heating when your supposed to be cooling & vice versa. I am of course assuming you have two sockets being controlled by the stc controller.

wiring looks ok now
you were missing a wire on first picture

Because i have nothing to lose at this stage i am going to wire the freezer into the heater circuit and the tube heater into the chiller circuit just to rule out the stc 1000 being wrong way around.

That was because i had no tube heater connected at the time.

Now i have it all fully rewired and even with the cooler and heater indicators off(temp has bee reached) the bastard freeer is still running.

In the absence of a multimeter - get a battery, a bulb and a piece of wire.
Remove power and check for continuity.
If you do not do this you are wasting everyones time including your own.
