the gas for pilot burner, and pilot burner
remains lit, then the system is working
properly.

an adequate flame during the trial for
ignition (90 seconds):

light the pilot gas before ignition control
module locks out, there may not be

to remove power and re-set the module.
Wait 5 minutes between ignition tries for
unburned gas to vent.
Manually operate pan position/down limit
switch and sparking should resume. The
module may need to be re-set several
times before ignition takes place.
