Here is my problem.  A piece of element ohmed properly before installation.  I placed the SW element in place, used silcone caulk to keep it in place (on a piece of WEDI board) and also used the same caulk to adhere the floor covering.  After drying time, the element did not register any ohm's and will not heat up.  I removed the floor covering, pulled the element out, rechecked the ohm's and still nothing registers.  It is like the piece of material is dead.  What's wrong?
