911 Fridge issue on cross country trip. Gas mode does nada

When the gas valve clicks on, try lighting it manually. If it lites, then it maybe just needs a new igniter/flame sensor.
If all else fails, and you need to run it on gas, just hot wire 12v to the gas valve, manually lite it. If it won't lite, the gas valve is bad ??? If it lites, let it burn several hrs till stuff get very cold, then un hook 12v.
You don't need to burn at nite, just fire it once or twice during the day for several hrs.
