On my toaster, the inner elements do not glow as brightly and therefore don't get has hot as the outer elements causing the bread to be toasted unevenly from side to side. These inner elements are designated as the 'bagel' toasting sides, but activating the 'bagel' button only causes the outer elements to go dark and does not make the inner 'bagel' elements glow any brighter. The connection to the inner elements seems solid, so I suspect a failure with the circuit board that controls the electrical flow to the elements. Any thoughts? Thanks!
