Gary,
Robert is correct.
You will have an open thermal fuse.
To replace these is relatively simple.
I use a SK876, available from Andrews/Tritronics for a couple of bucks.
DONT be tempted just to bridge the terminals or use a standard fuse in its
place.
With the price of the thermals there is no excuse to take a chance like
that.

That most likely has a thermal fuse wrapped inside the transformer.
try measuring from either side of AC cord to primary of transformer you will
find where it connects and can solder in a fuse for testing.
