IGNITER
The igniter is an electronic device that produces high
voltage to create a spark at the burner, only on gas
mode.
First verify proper voltage at the positive (+) and ground
(–) terminals of the ignitor. The reading should be within
one volt of incoming voltage at the main terminal block
during trial-for-ignition (approximately 45 seconds). A
voltage drop of more than one volt would indicate a
loose connection or a circuit board problem.
Next, disconnect DC power at the refrigerator terminal
block. Remove high voltage cable from igniter. Recon-
nect DC power – the igniter should produce a sparking
sound, during trial-for-ignition (approximately 45 sec-
onds). If not, replace the igniter. If sparking sound, the
igniter is good.
The igniter installed on the refrigerators as original
equipment is part number 2931132019 (RV Gas Model
679). This igniter is rated 50 MA. This igniter may also
be used on any other model.
DO NOT install the Channel Mark 6, Model 12E igniter
(shown below) as a service replacement part.

Installing the Channel Mark 6, Model 12E, rated 25 MA
can result in failure to ignite on gas if the DC power
supply is below 12.5 volts DC. The igniter will see low
voltage and not produce a spark, resulting in flame
failure lockout.
Installation of the Channel Products, Inc., Gasliter Mark
6, Model 12E, will VOID the Warranty on the refrigerator.

HIGH VOLTAGE CABLE

Disconnect DC power at the refrigerator terminal block.
Disconnect high voltage cable from electrode. Recon-
nect DC power. If sparking starts during trial-for ignition,
the cable is good. If there is no sparking during trial-for-
ignition, disconnect DC power and disconnect high
voltage cable at the igniter. Reconnect DC power. If
there is a sparking sound from the igniter during trial-for-
ignition, then replace high voltage cable.
ELECTRODE
First, do a visual check for cracks or breaks on the
ceramic insulator. Verify the
mounting bracket is
attached properly to the
above is found, replace the electrode. The spark gap
must be set at three sixteenths (3/16") of an inch and tip
of electrode above the slots in the burner.
If igniter and high voltage cable are good and there is no
spark at the tip of the electrode, replace the electrode.
