I keep hearing about flames blowing out on these refrigerators. When the fridge is working, try blowing it out. Auto-ignition simply re-lights it. Now turn off the gas and listen while it clicks away attempting to re-light. Long time before it gives up, right? Conclusion1: It would take a very long sustained gust to blow the flame out so that it stays out. Conclusion2: It's probably not the wind that's the problem. When I struggled with similar problems, I eventually picked out the proper Dinosaur replacement board and have had no problem since.
