Don't want any help or advice. Just would like an opinion or two based on your field experience relative to the following; Got 3 yr. old Gas fired Trane with a Western Digital board and a WD Silicon Nitride Igniter. No heat problem-Service Tech quickly and correctly diagnosed a failed Igniter. I've read that the typical life of an Igniter is about 3-5 yrs but you can get at least 3 plus additional years with the Silicon Nitride type. So, did the one installed in my furnace fail prematurely (non typical-infant mortality) or is the longer life a bit exaggerated and just more hype to justify the higher cost? (Have a Service/Manteca contract so cost is not a factor for me) Also, does the practice of lowering the temperature at night and then resetting it in the morning (ala programmable thermostat) in time, actually have a negative impact on the furnace hot section components? That is, because of the long(er) time components are exposed to the full blast of the furnace (as the house is brought back up to the new set temperature) their useful life can be reduced. MLD
