I have a Luxaire furnace and when it works it works fine, but every other day I have to reset it because the ignitor will not ignite. I have replaced it already and it did it again last night. I get a little flame icon on my furnace. What could be causing a brand new ignitor to only occasionally not ignite?


The igniter is powered by the board so that is one possibility but if it's glowing and just not getting gas to light then that's a different issue and has a few possibilities.
