Last week, our gas oven (20+ years old, came with the house) quit working. It wouldn't heat up, and when I took the bottom cover off, it appeared that the igniter was glowing, but not bright enough (according to my internet research).
I briefly looked into a new range, something like $450 delivered and installed from Sears and the old one hauled away (shockingly, the cheapest/best option was, in fact, Sears). I checked craigslist, and found a good one for $200. I started looking into truck rentals and the best way to get rid of an old range... when I backed up.
A new igniter was $24 on Amazon and eligible for free next-day delivery. I figured that $24 was worth the chance of being able to fix it.
It arrived, and it took about 10-15 minutes of fumbling around to swap it out. Then I preheated the oven to 400F like it was nothing.
Gas ovens are incredibly simple mechanically. I had no experience before this, and it was super easy.
Additionally, we used our oven-less time as an opportunity to fire up the grill and make some excellent kebabs.
