Hey guys!

I have a question. I just finished building my new rack after I sold the old one. I just got the heat tape wired yesterday and the new Herpstat 1 hooked up. However, I have a problem!

I know that flexwatt can vary between shelves. All heat tape strips are wired in parallel and soldered on directly to wires. My problem is that one shelf is highly variably compared to others. Its significantly lower than the rest, about 11 degrees on average. It doesnt even seem as if its working at 83 degrees where the rest are at 95-- where they should be. Its also in the middle of the rack, so I'm not sure whats up with that.

Can you guys help me troubleshoot? Maybe you've had similar circumstances in the past?

Thanks guys! All help is greatly appreciated!!
