The reset switch on the side of the furnace kills the whole unit. Sounds like you have an exhaust or ignition tube blockage (spider web, wasp nest etc) or your sail switch is faulty. Could also be the circuit board. As long as you have propane which Iím assuming youíve checked that, itís most likely one of those four things. Unfortunately they bury the furnace deep in the basement and make it almost impossible to work on without taking it out.
