More often than not, the reason for your knob light showing an unusual color or not turning off is because the power is not the correct polarity. If fixing this does not resolve the problem, then you should contact your local service center or Furrion directly for assistance.
When it comes to choosing the number of burners on your camper propane stove, there is no better option - only what is right for your RV or camper. You should take into consideration factors such as how big your counter space is, how big your family is, and how often you cook. 2 burner stoves are ideal for smaller families, those strapped for space, or those who only cook occasionally. Alternatively, 4 burner stoves are ideal for bigger families, larger or luxury RVs, and those who plan to cook a lot while on the road. 3 burner stoves sit somewhere in the middle and are a good compromise for those who straddle these two groups.
