Lance Squire 3000: Dometic Fridge not Lighting in Gas Mode?

The controls to the Dometic 3-way frig in my camper look different from the photo you posted, but they probably work much the same way. Have you tried to light the flame with a match? If you can't get flame, there is a problem with the gas supply. The igniter must be real close to the gas nozzle. I watched a tech bend sheet metal to make this happen. The igniter has only a single wire. Make sure it is properly attached - one time I pushed the wire back down into the cylinder, and it worked again.
