Doug, how does the board shut off the 12v to the reignitor and not the gas valve after the thermocouple senses flame. The same yellow wire feeds both 12v. Is this done on the board somehow? Thanks
Good question. Are you saying that the 12 volts on the yellow wire NEVER goes dead? I have never in 44 years had to check that voltage when diagnosing this type problem. Since the Yellow wire comes from the main control board, then the main control board controls the yellow wire. The spark electrode "may" also sense the flame and this tells the reignitor to stop sparking. NEVER had that come up. BUT the Thermocoupler DOES kill the power to the yellow wire IF there is no flame sensed. What I would do is connect my multi meter pos lead on the yellow at the reignitor and manually light the flame with a hand held lighter when asking for ignition. SEE if the reignitor still has 12 volt power(It should) or the gas valve would close. Doug
IGNITER
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-ianition
Next, remove high voltage cable from igniter. The igniter should produce a sparking sound, during trial-for-ianition. If not, replace the
igniter.
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.
