• If one Flame Sensor is dirty, clean them all. Allow
the Flame Sensor to cool and clean it with an alcohol
pad.
• Replace a Flame Sensor with damaged porcelain.
• Check for debris between the Flame Sensor tip and
burner.
• Adjust the Flame Sensor if the tip is touching
ground.
• Make sure all of the Flame Sensor connections are
tight.
Checking the Igniters
Another item to check, if the broiler is not lighting
properly, is the Igniters. It is possible for these
to get bumped during routine cleaning, causing the gap
between the electrodes to change.
• The spark gap should be 1/8″.
• Replace Igniter if the electrodes are damaged.
• Check all connections on the Ignition Module and
Igniter.
• If gas and spark are present but burner does not
light, verify proper location of the upper igniter
with regard to burner. The igniters on the the top
IR burners should be approximately 3/16" away
from the surface of the IR burner tile. The lower
igniter should be approximately 3/4″ from the lower
burner.
