I have a Trane XR90 Condensing Furnace that was installed in a newly constructed house in mid-2003. The ignitor (or "igniter, depending on who is spelling) has been a constant problem. I've had it replaced it once year. The first two times were blamed on gas supply being interruptions and the ignitor gettting heated up and cooling down repteadly. This time there has been no supply interruption. The ignitor is just "bad". I get no satisfactory explanation for this, especially when this type of ignitor (silicon nitride) is supposed to last for years.
To compound the aggrevation, this time the part is out of stock. So while I wait in the chill air of my den for Monday to roll around, I started surfing the web to see how hard the part (Trane's part number IGN00117) is to find and how much it costs. Last year I was charged $336 for the part and $99 for installation. It appears to me that the price for the part was grossly overstated. But before I go all ballistic on some hard working service tech, I'd like to know if I am right.
Anyone with any thoughts ??
