Regarding the stove burners, you said that they "worked fine after that". Did you mean they burned after being lit, or that the spark igniters did the job after one lighting with a lighter?
My stove in our 2008 3023 has the spark igniters. Since I turn off the gas at the tanks when I close it, it always takes several seconds before the burners will light for the first time, and then they work just fine after that.
If the burners don't light for over 15 seconds, I would open the door and wait a minute before trying again. I once lost my eyebrows after trying to light a heater in a truck camper. I had held the pilot valve open for 30 seconds or so and then used a match.
WOOSH!!! Fire shot out two feet into the air in front of the heater as the propane burned off.
Once burned, twice shy.
