Suburban SF-30F furnace won't turn on
My Suburban SF-30F furnace won't turn on. It will only click once. Has a Dometic Duo-Therm thermostat. A/C still comes on when moved to A/C but furnace won't come on. Can anybody help?

A newer model will not start the blower if the sail switch is stuck closed.
Chris is pretty much dead bang on, on his guesses. Sail switches do go bad and/or attract lint/dog hair/etc... stopping them from working.
