Anyone know what the normal resistance is when testing the heating element? Should it be a complete short (0 ohms)?
I would think that means element is broke. Should show resistance.
I recall reading on another thread that it should be around 29 to 32 ohms. If you are getting 0 welcome to the bad element club. Call Bradley and get a replacement - hopefully you are under warranty.
0 ohms is a dead short. Not likely to happen. Your ohm meter may not have the resolution at lower resistances to give an accurate reading. If it was really 0 ohms, the main fuse and/or the temp controller would fail immediately after turn-on. An open reading would indicate a bad element. The resistance would read infinity, not zero.
Brian posted that the resistance should be 27 - 32 ohms.
0 ohms is an open as the conductor has opened
Beefman I'm sorry to say thatis incorrect. As a technician for 25 years +, 0 ohms is full continuity, here is a good video I have found to demonstrate how to use an ohmmeter: http://www.youtube.com/watch?v=ocvaqGzvE2I
In my line of work, a 0 ohm reading on a copper phone line is considered a dead/hard short. Meaning your practically on it. We do have other equipment that will tell you the exact footage to a ground fault and short. But before the fancy equipment, we would take the ohms reading and multiply by a number depending on the gauge of the copper pair and it would give you the distance. Just my two cents. :)

Here's a thread I posted on the subject this past summer: Checking for Bad Element with Multimeter (http://forum.bradleysmoker.com/index.php?topic=22989.msg276965;topicseen#msg276965)
Yep just like a fuse.
