SOLENOID VALVE
When the refrigerator selects LP gas operation, DC volts
are sent to the solenoid coil which opens the internal
valve.
Check the solenoid coil with a properly calibrated ohm
meter. Remove the connector from the solenoid and
measure the resistance across the terminals. The proper
reading would be 49 ohms with tolerance range of ten
percent.
Next, hook up a manometer at the test port. Then check
for DC volts at gas valve terminals while the unit is in
trial-for-ignition (approximately 45 seconds). If DC volts
are present and pressure is low, replace the valve. If DC
volts are not present at the valve while the unit is in trial-
for-ignition (approximately 45 seconds), verify that the
wire at Plug 3, Terminal 2 on lower circuit board have
DC volts (9 or more). If the valve chatters, check for low
input voltage to the valve (below 9 volts DC).
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 refrigerator terminal block.
Remove high voltage cable
from igniter. Reconnect DC
power – the igniter should
produce a sparking sound, during trial-for-ignition
(approximately 45 seconds). 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.
