The sail switch is a small switch with an arm sticking into the circulation portion of the furnace. It is activated by the fan during start up. The switch statys operated during furnace operation.
If the sail switch does not activate the igntion system will not operate.
It has a very small operator on the switch. A small spec or so of debris can prevent it from operating.
Thanks, I'll have to take a look at that. However, I never hear the fan start up at all, but I might have slept through that I suppose. At this point I'm willing to try anything that someone can come up with.
