ITC1000 fried?

[odie]

Was wiring a new Inkbird and as soon as I plugged in the cooler I heard and smelled it fry. But no tripped breaker.

I’m pretty sure I had the wires correct. Plus all my other units, if I got something wrong it would either throw an error or trip the GFI breaker. But never fry.

I have an ITC2000 I tried and I get errors or trip breaker , but it won’t fry.

Defective unit??? I had another ITC1000 on this cooler that’s now on a freezer. So this cooler was working before with an inkbird.

Wiring diagram?

Tapped into constant Power and neutral from the GDM cabinet light and fan to terminal 1&2 on the stc. Just one of the pink thermostat wires into the cold load terminals. Plugged gdm into wall and poof.

STC? I thought it was an Inkbird? Which make and model is this thing, actually?
And what is this "pink thermostat wire" you're trying to use?

Let's try this again: an actual wiring diagram showing the actual controller and how you're actually trying to use it...

Cheers!

My bad. ITC. On the GDMs there are two pink wires going to the thermostat in the top of the cabinet. One is constantly hot.
There is also a constant hot black wire in the same location that feeds the display light switch and fan. And a white neutral that grounds the fan and light.
I’ll have to draw something up. But what is strange is when I had it wired before if I got something wrong it would just trip the breaker or give an error. For some reason this unit fried instead.

Tripping breakers is bad, especially if the breaker has a trip rating higher than, say, the relays in your controller.
There must be something fundamentally wrong to be tripping breakers and smoking relays...

original wiring. Evaporator fan runs constantly

how I “think “ I had the Inkbird wired before. Fan only running when compressor is on.

I did have an ITC1000 hooked up before and it ran fine for months. I should have never removed it :/

Does my wiring diagram even make sense ?

Ok. I’m officially an idiot. The new ITC1000 I bought is 12v and not 120v.

Got the new 110v one installed. Just like the schematic I posted. Works perfectly
