The GOOD NEWS: The furnace is fixed and Dom, Buds, and I are sitting pretty (and warm) in the house these days.
The BAD NEWS: The repair cost us 300 George Washingtons!!
The LESSON: A while back, a nice PG&E guy told us (for free) that the furnace probably needed a new ignitor. We chose not to DIY this one, because we had no clue about furnaces and just wanted it fixed already! We had someone come and test the furnace, and after a $65 half hour diagnostic, he found that the ignitor needed to be replaced....genius. after watching the guy repair it, we quickly realized this would have been a super simple fix. The part just plugs into an air switch type thingy. All you have to do is order a new ignitor and plug the hose into it! Well, the ignitor is not that cheap anyway, but you can certainly get it for less than $240 + $65.
