my Norcold wont stay lit ?

[Kenvb]

I just bought a 1990 Glendale Royal Sterling from original owner whose son pulled it out of the garage and left it outside in the weather.
63,000 kms. 351 motor. $1000 cant go wrong. drove it home 25 miles.tires all cracked , new ones next week.

issue is the 3 way Norcold N51X Fridge. it works great on 110 and 12 volt. but only stays lit for 30 seconds on propane.. I cleaned it all out.blew out the lines. propane is at least 8 yrs old..but stove lights good with nice blue flame.pilot light on fridge is blue.but only for 30 seconds.. get a F code light on fridge..means lack of propane?
any ideas.

'F' Fault Code is 'No Flame' detected.
Spark Electrode provides the high voltage spark to ignite the gas AND is also used for 'flame sensing'. Flame creates an AC current which gets rectified into a DC current which circuit board is looking for....this milliamp signal is used as proof that gas has ignited/stayed ignited.


Spark Electrod gap should be 3/16" and centered over burner slots so it is engulfed in flame when ignited.
Spark electrode needs to be claen of soot/carbon so milliamp signal is not inhibited (clean with emery cloth)


Troubleshooting steps/tests can be found on pg 19 of this service manual
