Trouble shooting "heat tape" (flexwatt/fermwrap)
 

I got a flexwatt heater from my local homebrew store. When I plugged it into my temperature control device, it was not warm after 30 mins. I then plugged the flexwatt straight into the wall, and still no warmth after 30 minutes.

I am really at a loss what to do, since there does not seem to be a manufacturer of this item with FAQ/troubleshooting information. Furthermore I am not very electrically savvy so I am not really sure what to be checking.

Any help would be greatly appreciated since my saison is sitting at 68 instead of 80 right now!
