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.
