problems with a trane furnace!!!

[newguy9898]

hello everybody, im in a bit of a rut i was wondering if someone can help me. i have a trane xr80 and it gave out about two weeks ago. it jus started blowing out cold air. so i went down to check it out and the led light signaled that the problem was with the ignitor. so i went to the store for the ignitor and i replaced it and it worked fine. 5 days later it gave out again, so i called one of my friends and asked him if he saw a problem with it and he said it was the ignitor and that the store may have given me a lemon so i went and bought another ignitor. again it worked for about five days and it went out again. i need somebodys help to diagnose this problem please. the furnace is about 6 yrs old but i wanna also think that the problem lies within the control board.

thank you all!

With some igniters you must careful not to touch the filament, much like halogen bulbs. Also, check to be sure the input voltage to the igniter is not too high and causing premature burnout.
