Issue with heat tape temps in rack...

[amsmtf]

Possibly a useless question, but are all the cords the same length? It could possibly be a cord resistance difference (though, a couple inches doesn't really do much). It just seems odd that the 3rd shelf down has the heating issue (or maybe that square of tape has faulty wires inside?).

I'll check that when I get home. I'll need to take temps again though, because now I'm thinking that there is possibly a fluctuation between spots on each heat mat AND random fluctuation overall between 88~97 on each mat. So when I took the temp on one mat and then took the temp on another, I could have just happened to measure different spots, if you know what I mean.

When I measured yesterday, it was 94 at random points on other mats too (but still overall less hot than the 3rd mat), so now I'm not so sure if it's always just the 3rd mat.
