What to Do

The combustion quality
of  burner  flames needs
to be determined visually.

Plug on cooktop is not
completely inserted in
the electrical outlet.

Gas supply is not
connected or turned ON.

A fuse may be blown or a
circuit breaker tripped.

Burner parts not replaced
correctly.

Igniter tip broken or bent.

Igniter switch defective.

Spark module defective.

Control knob is still in
the LITE position.

Be sure the knob is in
the OFF position.

Incorrect cleaning
methods being used.

Hot cooktop came into
contact with these
substances.

• Use the illustrations below to determine if the burner
flames are normal. If the burner flames look like A, see
Flame Adjustments. Normal burner flames should look
like or C, depending on the type of gas you use. With
LP gas, some yellow tipping on outer cones is normal.

A–Yellow flames                      B–Yellow tips                            C–Soft blue flames
Call for service                 on outer cones 

               Normal for natural

                                     Normal for LP gas        gas

• Make sure electrical plug is plugged into a live,
properly grounded outlet.

• See the Installation Instructions that came with the
cooktop.

• Replace the fuse or reset the circuit breaker.

• Make sure the pins in the burner head are properly
located in the burner base holes.

• Replace igniter.

• Replace igniter switches.

• Replace spark module.

• Turn the knob beyond the LITE position to the desired
setting.
• Turn the burner off and relight. If ticking is still
present, replace the igniter switches.

• Remove knob by pulling it straight off the stem and
check the bottom of the knob for any buildup of soil. If
ticking persists, replace the igniter switches.

• Use recommended cleaning procedures as described
in Use and Care manual.

 • See the Cleaning the Glass Ceramic Cooktop
section of the Use and Care manual.
