Dometic Trouble Shooting Guide

Last week we unplugged our '94 Tioga to go for a week long trip. The refer wouldn't fire up on propane. No click no buzz not even a whimper. Usually this is due to rust falling down the flue and landing on the sparker. Not this time. We drove about 5 miles and tried again. Bingo. It started and ran flawlessly for an entire week.

Does anyone have a link to the trouble shooting procedures so I can avoid this Chinese fire drill next time out?

thanks-
