STC1000 Throws Breaker...

[MetalMan2004]

So I am wondering if anyone can tell me why my STC1000 is throwing the breaker. I wired it up using a video I found on here so I believe that part is right.

It is the 110V STC1000 with 2 single that are 110V. I am using this freezer: http://www.homedepot.com/p/GE-7-0-c...CM7SUWW/203547578?N=5yc1vZc3nr#specifications

I am very confused because I plugged it in and it worked until the freezer got cool enough to shut off the cooling feature. As soon as the cooling feature cut off the breaker threw. Tried it again and got the same thing. I am confused because I would think the breaker would throw while the cooler was running, not when it was off.

Any suggestions anyone?

Just spitballing as I don't think it would cause the issue you are experiencing but did you remember to break the connector tab between the switched side of the outlet that the cooling and heating circuits are connected to?

I actually used 2 separate single outlets so they are wired separately. Thanks for the spitball though. Any attempts at helping me fix it are appreciated!

Wired improperly, dead shorts when cooling relay opens?

I'll go back and recheck my wiring again. You may be right, but I used a video on this forum and followed step by step. Doesn't mean I didn't miss something though.

Also not a EE but wouldn't the 10 amp fuse blow first before the 20 or 30 amp breaker? (assuming you added a fuse)

Which video did you use? Can you link to it?

Also, I would disconnect your freezer and see if it works...then try disconnecting your heat source....you can maybe pinpoint the issue that way? Of if you have a voltage meter you could use that (probably not necessary though if you don't own one).

Start with disconnecting and removing all of the wire for the second "heat" outlet.

Post a clear photo of the wiring.

My first thought was the same.

But when first plugged in, the cooling relay coil won't energize until the ASC delay times out. Thus the initial condition is "Not Cooling Yet", so that theoretical wiring error would manifest itself immediately.

Need to think about this tomorrow

But a good picture of the wiring would probably solve this mystery...

Cheers!
