• System Sentinel

all models employ a

diagnostic panel utilizing

light emitting diodes (L.E.D.),

corresponding to the number

and location of each heating

element. L.E.D.’s are

energized when the electric

elements are operating. An

unlit L.E.D. pinpoints the

exact location of a non-

functioning element, making

element operation diagnosis
