Product review (5 stars): Fixed our oven ourselves
Rather than spending $100 to call out our home warranty people, we decided to try to fix our oven ourselves.  It wasn't getting hot, and some internet research told us to try replacing the igniter.  My husband did this himself using information he found online.  It was not difficult, and he's not particularly handy.  The oven works perfectly now, and it cost us less than $40 to fix it.  This was almost 2 months ago and it's still working just fine.
