The igniter reigniter, used on certain
Dometic
model refrigerators, operates on 12 volt current.
On gas operation the igniter senses the resis-
tance through the flame between the electrode
and burner. When there is no flame at the
burner, the resistance is high and the igniter
begins sparking to light the burner. As soon as
the flame is lit, the resistance between the
electrode and burner drops and the igniter
stops sparking. The resistance is monitored by
the igniter, and, if for any reason the flame
goes out, the igniter begins sparking until the
burner is lit. This insures that the flame will
always be lit when desired. Each time the
igniter reigniter system sparks, a light will
illuminate on the lower left front corner of the
refrigerator.
If the electrode does not spark first, make sure
the igniter is receiving 12 volts. If the igniter is
receiving 12 volts and produces no spark, it
must be checked for operation.

Turn the refrigerator off and remove the wire
between the electrode and igniter. Now turn the
refrigerator to the gas mode. If no internal
clicking sound is heard the igniter is defective.
It is important to remove the high voltage wire
that goes to the electrode from the igniter when
you are checking the igniter for operation. The
high voltage wire and the electrode can be
shorted to ground causing the igniter reigniter
to think that the flame is lit, resulting in no
spark on gas operation.

The distance between the tip of the electrode
and the burner, known as the spark gap,
should be 3/16 of an inch. A greater distance
will create a slow spark causing the light to
blink. A lesser distance will create a fast spark
that may not light the burner.
