My 12 year old Keeprite furnace is heating the place OK but its cycling
without firing up intermittently. Sorry for the non-technical
description but here goes: when I listen to it fire up normally, I hear
a click followed by the flue fan (draft inducer) motor coming on and
then the gas ignition and heat. But recently, it has started doing all
of these without the gas ignition and heat. It sounds like its trying
to fire up but failing for soem reason. Anyone got any suggestions
before I call in a tech.

Thanks.
