Radiant elements have a limiter that allows the element to
cycle on and off, even at the HI setting. This helps to
prevent damage to the ceramic smooth top. Cycling at the
HI setting is normal and can occur if the cookware is too
small for the radiant element or if the cookware bottom is
not flat.
For efficient cooking, turn off the element several minutes
before cooking is complete. This will allow residual heat
to complete the cooking process.
Start most cooking operations on a higher setting and
then turn to a lower setting to finish cooking.
A glowing red surface heating area extending beyond the
bottom edge of the cookware indicates the cookware is
too small for the surface heating area.
The surface control knobs do not have to be set exactly
on a particular spot. Use the graphics provided as a guide
and adjust the control knob as needed. Each surface
element provides a constant amount of heat at each
setting. Refer to Table 1 for suggested power level
settings.
