Dometic fridge shut off

[givemeaboost]

My Dometic fridge shut off for some reason when cruising down the road. We didn't notice that the check light was on til the next morning. As far as I know we lost everything that was perishable as it was about 55 degrees in there. I shut it down and restarted it on propane and it started and is still working today. All I can think of what caused it to go out was we hit three rather large bone jarring bumps on the highway. Could this cause a shutdown ?

Check Light.....Fault Code for Loss of Flame
LP System is very low pressure (11"WC -- 0.39 psi)
Propane has a narrow flammability range --- 2% to 9.5%

Disruption of fuel/air mixture

Check the spark electrode position....needs to be engulfed in the flame when ignited
Spark Electrode needs to be clean of soot/carbon....use emery cloth
Spark Electrode wire connection needs to be tight/clean at transformer on circuit board

Thanks, Old Biscuit. I will check those out.

One other thing to check
Thermocouple ....probe installed just above burner. Some models use that for flame proving vs the Spark Electrode

What Dometic Model do you have???

Sometimes wind while driving can lower the sensor temperature enough to extinguish the flame. Possibly a cross wind with high driving speeds. Some refers are more sensitive to wind than others.

Following Old-Biscuits instructions may improve results.

I just used it for four days without any problems so I'm inclined to believe that it was caused by wind. one lesson learned was to keep an eye on the fridge light.
