Wow, so cool to finally find something online about my very problem! My Caloric lp wall oven did the EXACT same thing, doors would blow out when ignitor finally caught. Doors are on nice strong springs, though, and they would spring shut again. Eventually, I would just leave one door open a little, turn the knob up to about 350, then when it lit up (after anywhere from 2 to 10 minutes,) I would close the door for preheating. I just figured it was old, original to the house built in the fifties, so something to live with and not too inconvenient. Certainly not a worry for someone like me, who grew up with gas ovens and stovetops.
Now recently, and just in time for Thanksgiving, mind you, the oven has stopped lighting altogether. After following this thread, I am going to disassemble it and try cleaning it thoroughly, to see if that makes a difference. I have the same problem as listed above, the space it occupies now is 24" x 38", not your average size for today's models, and as it sits in a cabinet at the end of the countertop and a doorway, not easily modified.
