There are a couple threads on the Travato fridge - do a search for the details.
It's a 3 way fridge. To light the propane, you have to turn the knob and then hold down the switch to light it until the gauge indicates it's fired. One owner reported his fridge's flame blowing out and he had to take it in for repair under warranty. Another reported some difficulty starting it on propane.
I've had no problems. So if the point of posting this thread is to imply that Travato's are all having refrigerator problems, that is simply not the case, as reports of issues are only 2.
