Dometic Refrig won't start on Gas FOLLOW UP

Just went over and fixed it.......don't know what I did to fix it...but it works. I took the back cover off, and blew hard near the burner....went up and fired up one of the cook top burners..waited a few minutes and turned the refrig on AC....I had the generator and engine running.......I couldn't tell if the refrig was on or not...but the reset button didn't lite up....so I assume it was working..I next switched over to gas and it lit off. I tried it a few different times with the generator running and off, making sure it would switch from AC to gas and no problems......so if anyone needs any help fixing their refrig, just let me know, I'm an expert...NOT LOL
Thanks for all the info
