Checking the Cooktop
Problem Check
The burner lights but the
fl ame goes out when the
control knob is released Each burner gas control valve includes a thermoelectric solenoid fl ame safety valve
(FSD) that is normally closed. There is a sensor probe mounted on each burner. To light a
burner the user must push in the control knob and turn to the full on position. Pushing in
the knob overrides the safety valve and allows gas to fl ow to the burner while the knob
is pushed in. The spark ignition lights the burner and the fl ame heats the sensor probe.
When it gets hot enough the sensor produces a very low voltage electric current that
keeps the safety valve open when the control knob is released.
Try holding the knob in for longer. The FSD should hold in after a few seconds, if it does
not hold in after 10 seconds the sensor may not be getting hot enough because there is
problem with the burner head or the sensor position is incorrect.
Check the burner head is clean and the fl ame ports are clear. Check that the burner head
is sitting down correctly on the burner base
If this does not solve the problem try changing the sensor probe
The burner fl ame goes out
when the control is turned to
